Stop Condensation at the Source

Wykamol ThermalDry Anti Condensation Coating is engineered to tackle one of the most common causes of internal damp: warm, moisture-laden air meeting cold surfaces and dropping below its dew point. By raising the temperature of the paint film itself, the coating delays dew-point reach on walls and ceilings, providing an immediate barrier to surface wetting and the damage it triggers. Laboratory and field experience indicate it can take up to 60% longer for condensation to occur on treated surfaces compared with standard paints, delivering a measurable improvement in day-to-day comfort and finish longevity.

 

Microsphere Technology for Thermal Performance

At the core of ThermalDry is a dense matrix of hollow glass microspheres suspended in a durable styrene-acrylic binder—functioning like a microscopic thermal flask. This structure reduces thermal conductivity at the coating, reflects radiant heat back into the room and elevates the wall’s surface temperature. The result is a genuine dew-point shift that helps interiors feel warmer to the touch, curbs cyclical wetting and drying, and protects decorative finishes from premature deterioration.

 

Breathable, Water-Repellent Protection

Once cured, the coating is water-repellent to liquid moisture while remaining vapour-permeable enough for typical internal substrates, helping spaces stay drier without trapping damp within the fabric of the building. Its antibacterial formulation resists colonisation, supporting hygiene in everyday use, while the water-based, low-odour chemistry enables rapid return to service in occupied properties and integrates cleanly with standard maintenance regimes.

 

Targeted Defence for Cold Bridges and Humid Rooms

ThermalDry is purpose-built for problem areas where cold bridges and high humidity combine: exterior-facing masonry walls, concrete lintels above windows and doors, corners, ceiling perimeters and under-insulated rooms. In kitchens, bathrooms and utility spaces—where steam generation is frequent—the coating reduces bead formation on paint films and helps protect grout lines, plastered walls and previously decorated surfaces from recurrent condensation.

 

Refurbishment-Ready and Versatile Across Sectors

Designed for domestic, commercial and industrial environments alike, the coating integrates seamlessly into refurbishment programmes; once dry, it can be over-painted with standard emulsion or finished with wallpaper without sacrificing thermal performance. For landlords, housing associations, facilities managers and homeowners seeking an effective anti-condensation paint, thermal insulating paint or mould-resistant wall coating, Wykamol ThermalDry offers a practical, long-term specification choice that reduces maintenance cycles and, when paired with sensible ventilation and moisture management, helps prevent black mould while improving occupant comfort.

 

 

Signs of Condensation Dampness & Black Mould

  • Water Beading on Cold Surfaces: Visible droplets forming on painted walls, ceilings, windows reveals and lintels—especially in mornings or after cooking/showering—indicate the surface temperature has dropped below the dew point. Persistent wetting raises the risk of decorative failure, peeling paint, and microbial growth.

  • Black Mould Spots and Staining: Clusters of dark specks or velvety patches at external corners, behind furniture, around window heads and on ceiling-wall junctions are typical of condensation-related mould. Left unchecked, this can undermine air quality, aggravate asthma and allergies, and degrade plaster and finishes.

  • Musty Odours and Poor Air Quality: A stale smell in bedrooms, bathrooms or kitchens often accompanies intermittent condensation. Prolonged exposure increases health risks for vulnerable occupants and signals a need for anti-condensation measures and improved ventilation.

  • Peeling Paint, Blistering and Wallpaper Lifting: Repeated wetting weakens adhesion; paint can blister, and wallpaper seams may curl or disbond. This invites further moisture ingress, accelerates substrate deterioration and leads to costly redecorations.

  • Cold-to-Touch External Walls and Lintels: Areas that feel notably colder than the rest of the room (thermal bridges) are prime locations for dew formation. Without intervention, these cold spots drive recurring condensation and mould cycles.

  • Persistent Window Reveals and Sill Damp Patches: Damp margins around frames and sills point to surface temperature differentials and high local humidity, increasing the risk of mould colonisation and damage to sealants and finishes.

 

 

Product Benefits

  • Thermally Insulating, Dew-Point Shift: The hollow glass bead micro-technology raises surface temperature and shifts the dew point away from the paint film, significantly reducing condensation risk on cold walls and ceilings.

  • Proven Anti-Condensation Performance: Treated surfaces can take up to 60% longer to develop condensation compared with standard paint, providing a wider margin of safety during peak humidity events in bathrooms, kitchens and utility rooms.

  • Water-Repellent, Warm-Touch Finish: Once dry, the coating is waterproof to liquid water yet feels warm to the touch, discouraging condensation beading and improving comfort in everyday use.

  • Helps Prevent Black Mould: By limiting surface wetting and incorporating antibacterial properties, the coating disrupts the conditions that allow mould and fungi to establish, supporting healthier indoor environments.

  • Compatible with All Decorative Finishes: May be over-painted with conventional emulsions or finished with wallpaper without diminishing thermal or anti-condensation performance, simplifying refurbishment and colour changes.

  • Extends Life of Paint and Wallpaper: Reduced wetting/drying cycles and improved surface temperature stability help paints and wallcoverings last longer, lowering maintenance and redecoration frequency.

  • Eco-Friendly, Water-Based Formulation: Low odour and easy clean-up support use in occupied properties, while the water-based styrene-acrylic binder and durable microspheres deliver long-term performance with minimal disruption.

  • Ideal for Cold-Bridge Hotspots: Particularly effective over lintels, window and door reveals, external wall perimeters and uninsulated or partially insulated substrates where thermal bridging drives condensation.

  • Simple, Practical Upgrade: Applies like a standard emulsion with Brush or Roller, enabling rapid anti-condensation upgrades without the complexity, thickness or cost of internal insulation boards.

Health & Safety Recommendations

Read the label and safety data sheet in full before use. Ensure good ventilation during application and drying, particularly in kitchens, bathrooms and utility rooms where humidity is high.

Wear suitable PPE including gloves and eye protection; avoid inhalation of mist and prolonged skin contact. Do not ingest. In case of contact with eyes, rinse immediately with clean water and seek medical advice if irritation persists. Keep out of reach of children and pets. Do not apply near open flames or hot surfaces. Dispose of waste paint, contaminated wash water and empty containers in accordance with local regulations.

As a water-based, low-odour product, Wykamol ThermalDry Anti Condensation Coating is suitable for occupied properties when normal hygiene and ventilation practices are followed.

 

 

Substrate Suitability

ThermalDry is designed for interior mineral substrates such as plaster, skim coat, plasterboard, cement render and sound, previously painted walls and ceilings.

It is especially effective on exterior-facing walls, lintels, window and door reveals, ceiling perimeters and other thermal bridge areas prone to condensation damp and black mould. Where the substrate is plastic, metal or other non-masonry material, consult the manufacturer’s data for a compatible primer or contact our technical support for guidance.

The coating requires a firm, clean surface to key to; highly polished, friable or powdery surfaces must be suitably prepared or primed before use. Do not apply to surfaces exhibiting active mould or fungal growth until they have been treated.

 

 

Surface Preparation

Remove surface mould and fungus thoroughly using Wykamol MCS1 Mould Clear Solution, following the product instructions, and allow the area to dry. Strip away loose or flaking paint, degraded wallpaper, grease, oil and other contaminants that may impair adhesion.

Fill cracks and defects with a suitable Crack Filler, allow to set fully, then sand smooth. Check for existing coatings, sealers or low-energy finishes that may inhibit adhesion; lightly abrade glossy paints to provide a key and vacuum off all dust. For plastics, metals or other specialist substrates, follow the primer advice from the substrate manufacturer.

Ensure the surface is dry, clean and free from condensation at the time of application. Where persistent moisture is present, improve ventilation and heating to bring the substrate temperature at least 3°C above dew point prior to painting.

 

 

Mixing

Open the tin carefully and gently stir by hand with a flat paddle to re-disperse the hollow glass beads uniformly through the paint.

Do not use a mechanical stirrer or vigorous shaking as this may fracture the beads and reduce thermal performance. Do not thin; product is supplied ready for use.

 

 

Application Method

Apply by Brush or Roller in two full coats. Cut in edges and details first, then roll the main areas, maintaining a wet edge and working methodically to achieve an even film. Aim for consistent coverage rather than over-brushing; excessive pressure can drive the beads into the substrate and reduce insulating effect.

Allow 2–4 hours between coats at 20°C and 60% RH. Apply the second coat perpendicular to the first where practical to improve uniformity. Do not apply below 5°C or above 30°C, and avoid painting if the substrate is cold to the touch, if condensation is present, or if high humidity or poor air movement will impede drying.

In bathrooms and kitchens, keep extraction running during and after application to remove excess moisture. Spraying is not recommended due to the microbead technology and risk of equipment abrasion.

 

 

Coverage

Coverage depends on surface profile and porosity. As a guide, a 2.5 L bucket covers approximately 5 – 6.25 m² after two coats, and a 5 L bucket covers approximately 10–12 m² after two coats.

This equates to a total applied rate of roughly 0.4–0.5 L per m² for two coats (around 0.2–0.25 L per m² per coat). Highly textured or absorbent substrates will reduce coverage; plan allowances accordingly.

 

 

Drying Time

At normal room conditions (approximately 20°C, 60% RH) each coat dries in 2–4 hours. Lower temperatures, higher humidity and poor ventilation will extend drying times; higher temperatures and good airflow will shorten them.

Do not force dry with unvented heaters that add moisture to the air. Ensure the coating is touch-dry before recoating and allow the second coat to dry for 2–4 hours before finishing.

 

 

Finishing

Once the second coat has dried for 2–4 hours, ThermalDry may be over-painted with standard interior emulsions or finished with wallpaper without reducing its effectiveness. Where possible, select quality decorative finishes and adhesives appropriate to the room’s moisture load.

In rooms with chronic humidity, pair the coating with effective background ventilation and mechanical extraction to maximise anti-condensation performance. Avoid heavy sanding of the finished film; any nibs should be de-nibbed lightly to preserve the integrity of the hollow glass bead layer.

 

 

Cleaning

Clean brushes and rollers immediately after use with clean water. Do not allow washings to enter watercourses or drains; dispose of in line with local authority guidance.

Any splashes on adjacent surfaces should be wiped away promptly with a damp cloth. Once dry, residues are more difficult to remove and may require gentle mechanical action.

 

 

Other Information

ThermalDry is a water-based, styrene-acrylic, copolymer dispersion incorporating micro-technology in the form of hollow glass beads of approximately 50 μm diameter with a crush strength around 500 psi.

The coating is water-repellent when dry and produces a warmer-to-the-touch surface, delaying the onset of condensation—tests indicate it can take up to 60% longer for condensation to form compared with conventional paint. Two coats are necessary for optimum performance. Apply only between 5°C and 30°C.

The product density is approximately 0.77 kg/L. Store the container upright in a cool, dry place, protected from frost and direct sunlight, and keep the lid tightly closed when not in use.

ThermalDry is intended as part of a holistic condensation control strategy; combine with adequate heating, controlled ventilation and moisture management for best results. For unusual substrates or site conditions, or if in doubt about primers and compatibility, consult our technical services before proceeding.

Q) What is Wykamol ThermalDry Anti Condensation Coating and what problem does it solve?

A) Wykamol ThermalDry Anti Condensation Coating is a water-based, styrene-acrylic interior paint engineered to combat condensation and the black mould that follows. It contains 50 µm hollow glass beads dispersed through a durable binder, creating a low-conductivity, warm-to-the-touch film that raises surface temperature at the wall face. By lifting the surface above the dew point, ThermalDry delays the moment when airborne moisture condenses into droplets, meaning damp patches and bead formation are far less likely during daily peaks in humidity. Once dry it is water-repellent to liquid water yet practical for typical interior substrates, so rooms feel drier and finishes last longer. The coating is low odour, eco-friendly and antibacterial, which makes it suitable for occupied properties and sensitive areas. It is purpose-built for cold external walls, lintels and other thermal bridges in homes and commercial buildings where persistent condensation undermines decoration and indoor air quality.

 

Q) How does Wykamol ThermalDry Anti Condensation Coating work to reduce condensation and mould?

A) Wykamol ThermalDry Anti Condensation Coating works by altering the thermal and moisture behaviour at the paint film. The hollow glass beads act like microscopic thermal flasks, reducing heat loss through the coating and reflecting radiant warmth back into the room, which raises the measured surface temperature. When the surface stays warmer, the dew point is effectively shifted away from the wall face, so humid air must cool further before water condenses. Laboratory and field experience indicate treated surfaces can take up to 60% longer to develop visible condensation compared with standard emulsions under comparable conditions. Because the dry film is water-repellent, occasional moisture beads do not soak in, which helps the area dry quickly and discourages fungal colonisation. The antibacterial formulation adds an extra layer of hygiene by resisting microbial growth on the paint film. Together, these effects cut the wetting–drying cycles that drive black mould and decorative failure.

 

Q) Where should Wykamol ThermalDry Anti Condensation Coating be used for best results?

A) Wykamol ThermalDry Anti Condensation Coating is most effective on interior surfaces that run cold or see frequent humidity. Priorities include exterior-facing masonry walls, window and door reveals, concrete or steel lintels and ceiling perimeters where thermal bridging is common. Kitchens, bathrooms and utility rooms benefit due to repeated steam generation, as do north-facing or under-heated bedrooms that struggle to stay above dew point overnight. In social housing, HMOs and rental portfolios, it offers a quick-return upgrade that helps reduce mould complaints and redecoration cycles. Offices, welfare areas and plant-adjacent rooms with intermittent heating also gain more stable surface conditions. The coating integrates neatly into refurbishment programmes because it applies like a standard emulsion, allows rapid return to service, and provides a warmer, water-shedding surface that extends the life of subsequent decorative finishes.

 

Q) Which substrates are suitable for Wykamol ThermalDry Anti Condensation Coating and which need special attention?

A) Wykamol ThermalDry Anti Condensation Coating is intended for interior mineral surfaces such as plaster, skim coat, plasterboard, cement render and sound, previously painted walls and ceilings. It adheres well when the base is clean, firm and dry, making it ideal for typical domestic and commercial interiors. Highly polished, friable or chalky surfaces require appropriate preparation or priming to provide a reliable key. Plastics, metals and other non-masonry materials may need a compatible primer—check the substrate manufacturer’s guidance or seek technical advice before proceeding. Do not apply over active mould; treat microbial growth first, allow to dry, then paint. Avoid surfaces with ongoing liquid water ingress or structural dampness that would defeat any anti-condensation coating; those issues should be resolved at source. When in doubt, a small adhesion and appearance trial is sensible before full application.

 

Q) Can Wykamol ThermalDry Anti Condensation Coating be over-painted or wallpapered without losing its effect?

A) Yes. Wykamol ThermalDry Anti Condensation Coating is designed to accept conventional decorative finishes without compromising its thermal and anti-condensation function. Once the second coat has dried, you can apply standard interior emulsions to achieve your chosen colour scheme, or hang wallpaper using suitable adhesives for the room’s moisture load. The hollow glass bead matrix remains embedded within the film, so over-coating does not negate the dew-point shift or warm-touch benefits. Where heavy wallcoverings are planned, ensure joints are well bonded and surfaces are smooth to avoid localised cold spots at lapped edges. In higher-humidity rooms, pair the coating with reliable extraction and background ventilation so the whole system—paint plus environment—works together. If future colour changes are expected, ThermalDry provides a long-term base layer that continues to protect against condensation cycles beneath new finishes.

 

Q) How does Wykamol ThermalDry Anti Condensation Coating compare with normal emulsion paint?

A) Compared with conventional emulsions, Wykamol ThermalDry Anti Condensation Coating offers measurable thermal and moisture-management advantages at the coating interface. The micro-spheres reduce thermal conductivity and reflect radiant heat, so the film runs warmer and feels less clammy to the touch on cold days. Treated areas typically take much longer to reach visible condensation, especially during spikes after showering or cooking, which helps keep surfaces drier over 24-hour cycles. The dry film’s water-repellency means occasional moisture beads are less likely to soak in and cause blistering, peeling or staining. Ordinary emulsions lack this combination of micro-insulation and water-shedding, so they tend to wet and dry repeatedly, inviting mould and premature decorative failure. Because ThermalDry is water-based and low odour, it applies like a quality emulsion, yet it delivers a functional upgrade that extends maintenance intervals and improves perceived comfort in problem rooms.

 

Q) What coverage should I expect from Wykamol ThermalDry Anti Condensation Coating?

A) Coverage depends on surface texture and porosity, but practical planning figures are well established. A 2.5 litre pack of Wykamol ThermalDry Anti Condensation Coating typically covers about 5–6.25 m² after two full coats, while a 5 litre pack covers roughly 10–12 m² after two coats. That equates to an overall application rate in the region of 0.4–0.5 litres per square metre for the full system, or 0.2–0.25 litres per square metre per coat. Textured finishes, open-grained plaster or previously degraded areas will consume more material, so include sensible allowances when ordering. Aim for a consistent, even film rather than chasing maximum spread, because uniform bead distribution underpins the thermal effect. If you are treating only thermal bridges such as lintels and reveals, measure those lengths and widths carefully; spot treatments should feather into adjacent areas to avoid visible banding.

 

Q) How should I prepare surfaces before applying Wykamol ThermalDry Anti Condensation Coating?

A) Proper preparation ensures long-term adhesion and full thermal benefit. Begin by removing all visible mould and mildew with an appropriate biocidal cleaner such as Wykamol MCS1 Mould Clear Solution, following label instructions, then allow the surface to dry. Scrape away loose or flaking paint, lift failing wallpaper, and clean off grease or contamination that would interfere with bonding. Fill cracks and minor defects, allow to set and sand smooth, then lightly abrade glossy paints to create a key. Vacuum or wipe down to remove dust. Ensure the substrate is dry and at least a few degrees above dew point at the time of painting; if surfaces are cold to the touch or showing condensation, improve heating and ventilation first. For plastics, metals or other low-energy surfaces, apply a suitable primer as specified by the substrate manufacturer before using ThermalDry.

 

Q) Do I need to stir Wykamol ThermalDry Anti Condensation Coating and can it be thinned?

A) Wykamol ThermalDry Anti Condensation Coating should be gently stirred by hand with a flat paddle before use to re-disperse the hollow glass beads uniformly throughout the paint. Avoid mechanical mixers and vigorous shaking, which can fracture the beads and diminish the insulating effect. The product is supplied ready for use and should not be thinned unless the manufacturer has given specific guidance for unusual conditions. Maintaining the designed solids content helps you achieve the correct dry film thickness and bead packing, both of which are central to performance. If the material has been stored in a cool place, allow it to come to room temperature before stirring so the viscosity is consistent. Reseal the lid between coats and during breaks to prevent skinning and moisture uptake, which can affect application feel and coverage.

 

Q) What is the recommended application method for Wykamol ThermalDry Anti Condensation Coating?

A) Apply Wykamol ThermalDry Anti Condensation Coating by brush or roller in two full coats for a uniform, functional film. Cut in edges and details with a brush, then roll the main fields, working methodically and maintaining a wet edge. Use light, even pressure; over-brushing or pressing too hard can drive beads into the substrate and reduce the micro-insulation at the surface. Where practical, apply the second coat perpendicular to the first to promote even coverage and bead distribution. Spraying is not recommended because the bead technology can abrade equipment and may not lay down the optimal film structure. Keep extraction running in kitchens and bathrooms during and after painting to remove moisture and aid drying. Avoid painting if condensation is present or the substrate feels cold; the finish should be formed under stable, room-like conditions for best results.

 

Q) How long does Wykamol ThermalDry Anti Condensation Coating take to dry and when can I recoat?

A) In typical room conditions around 20°C and 60% relative humidity, each coat of Wykamol ThermalDry Anti Condensation Coating dries within approximately 2–4 hours. You can recoat as soon as the first application is touch-dry and firm, usually within that window. Cooler temperatures, higher humidity and poor air movement will slow the process, while warmer, well-ventilated rooms will shorten it. Do not force-dry with unvented heaters that add moisture to the air, as this can prolong drying and compromise appearance. After the second coat, allow another 2–4 hours before over-painting with standard emulsion or proceeding with wallpaper. As with any functional coating, final performance depends on achieving the correct film build, so resist the temptation to rush recoats on marginally dry surfaces.

 

Q) What environmental conditions are best for applying Wykamol ThermalDry Anti Condensation Coating?

A) Aim to apply Wykamol ThermalDry Anti Condensation Coating between 5°C and 30°C with moderate humidity and good air movement. The substrate should be dry and at least about 3°C above dew point to prevent moisture condensing on the film during application. In bathrooms and kitchens, run extraction continuously while painting and for several hours after to purge humidity. On cold days, gently pre-warm rooms so walls and ceilings are comfortably above the condensation threshold before you start. Avoid direct heat on the surface, hot pipes or strong sunlight that could skin the film too quickly and disrupt bead distribution. If conditions are variable across a property, schedule rooms so you always work in stable areas, returning to trickier spaces when temperature and ventilation can be controlled.

 

Q) What practical tips will improve results with Wykamol ThermalDry Anti Condensation Coating?

A) Success with Wykamol ThermalDry Anti Condensation Coating rests on even bead distribution and sound site practice. Stir gently before each session, decant manageable amounts into a scuttle, and reseal the main container promptly. Use medium-nap rollers that hold sufficient paint without excessive pressure, and focus on steady, overlapping passes to lay down a consistent film. Treat mould first and address moisture sources; pairing the coating with working extraction fans and background ventilation dramatically improves long-term outcomes. Feather treatments beyond the obvious cold patch to avoid a visual edge and to ensure continuity of thermal effect. After drying, avoid heavy sanding of the finished film; if needed, de-nib gently so you preserve the micro-sphere layer. Finally, educate occupants to ventilate during high-humidity activities—paint can delay condensation, but good habits keep conditions within its design envelope.

 

Q) Are there limitations to what Wykamol ThermalDry Anti Condensation Coating can achieve?

A) Wykamol ThermalDry Anti Condensation Coating is a powerful tool against surface condensation, but it is not a cure-all for moisture problems. It cannot compensate for structural dampness, liquid water ingress, or significant thermal defects that keep surfaces persistently cold. It is not intended for exterior use or for continuous wet areas inside shower enclosures where direct water impact is severe. Spraying is discouraged due to the risk of damaging the micro-beads and the difficulty of controlling film structure. The product relies on correct preparation and adequate film build; very thin or patchy application will reduce its effect. It should not be applied over active mould or to contaminated, friable or glossy surfaces without proper treatment and keying. Best performance is achieved as part of a wider strategy that includes sensible heating, moisture control and ventilation upgrades.

 

Q) Is Wykamol ThermalDry Anti Condensation Coating safe to use in occupied homes and how should I handle it?

A) Wykamol ThermalDry Anti Condensation Coating is water-based, low odour and suitable for use in occupied properties when normal hygiene and ventilation practices are followed. Provide adequate fresh air during application and drying, particularly in smaller bathrooms and kitchens, and avoid inhaling mists. Wear suitable gloves and eye protection, and wash hands after use. In the event of eye contact, rinse immediately with clean water and seek medical advice if irritation persists. Keep the product out of reach of children and pets, and do not ingest. Dispose of waste paint, wash water and empty containers responsibly in accordance with local regulations. The coating’s antibacterial nature supports better hygiene on the finished surface, but standard cleaning and ventilation remain essential to maintaining healthy indoor conditions.

 

Q) What technical data define Wykamol ThermalDry Anti Condensation Coating’s performance?

A) Wykamol ThermalDry Anti Condensation Coating is a styrene-acrylic copolymer dispersion loaded with approximately 50 µm hollow glass beads that have a crush strength around 500 psi, ensuring they survive application and service. The product density is roughly 0.77 kg per litre, reflecting the micro-sphere content and contributing to the warm-touch feel at the surface. Once fully dry, the film is water-repellent to liquid water yet practical for typical interior substrates, supporting a drier surface profile during humidity spikes. Under comparable conditions, treated areas can take up to 60% longer to show visible condensation than standard paint, indicating a meaningful dew-point margin. Recommended application temperature is 5–30°C with two full coats for performance, at a total usage of around 0.4–0.5 litres per square metre. These characteristics combine to produce a durable, functional finish that integrates seamlessly with standard decorative systems.

 

Q) How long will the benefits of Wykamol ThermalDry Anti Condensation Coating last and how should I maintain it?

A) The benefits of Wykamol ThermalDry Anti Condensation Coating are inherent to the dry film and persist for the life of the coating when applied at the correct thickness and used under normal service conditions. Because it reduces wetting cycles and sheds liquid water, it also helps protect subsequent decorative finishes, extending the time between redecorations. Routine maintenance is simple: clean with a lightly dampened cloth and mild detergent as needed, avoiding aggressive scouring that could thin the functional layer. If redecorating, over-paint with quality interior emulsion; the micro-insulation remains active beneath. Longevity is enhanced when the broader environment supports it—use extraction in wet rooms, manage indoor humidity and avoid blocking airflow behind large furniture. When these measures accompany the coating, users typically report more stable comfort and fewer mould-related call-outs over the long term.

 

Q) Can Wykamol ThermalDry Anti Condensation Coating be used in commercial or light industrial settings?

A) Yes. Wykamol ThermalDry Anti Condensation Coating is suitable for commercial and light industrial interiors where intermittent heating, process humidity or cold bridges drive recurring condensation. Offices, welfare areas, plant rooms, corridors and ancillary spaces benefit from the warmer surface temperature and water-shedding film, which reduces staining and maintenance disruptions. Because the coating is low odour and water-based, it can be applied with minimal downtime and quick return to service. In facilities management programmes, it provides a targeted, cost-effective upgrade for known cold-spot zones without the thickness or complexity of internal insulation boards. When specifying, ensure substrate preparation standards are met across varied finishes, and pair the coating with sensible ventilation policies to keep conditions within range. Its compatibility with over-painting allows future colour changes without losing functional performance.

 

Q) How should Wykamol ThermalDry Anti Condensation Coating be stored and handled before application?

A) Store Wykamol ThermalDry Anti Condensation Coating upright in a cool, dry place, protected from frost and direct sunlight to preserve viscosity and bead integrity. Keep the lid tightly closed when not in use to prevent skinning and contamination. If the product has been chilled, allow it to reach room temperature before stirring and application so it rolls out evenly. Do not leave the open can in steamy rooms for long periods; decant what you need into a tray and reseal the main container. Avoid stacking heavy items on the lid, which could compromise the seal. Observe shelf-life guidance on the label and rotate stock so older containers are used first. Good storage practice ensures the micro-technology is intact when you are ready to paint, delivering the expected anti-condensation performance.

 

Q) What common mistakes should be avoided when using Wykamol ThermalDry Anti Condensation Coating?

A) The most frequent pitfalls are inadequate preparation, poor environmental control and over-working the film. Skipping mould treatment or painting over damp, glossy or dusty surfaces undermines adhesion and performance, so complete those steps thoroughly. Painting onto a surface at or below dew point can trap moisture or cause early bloom; warm and ventilate the room so the substrate is safely above dew point before starting. Do not use mechanical mixers or aggressive stirring that could crush the beads, and avoid thinning unless instructed, as this reduces film build and thermal benefit. Heavy pressure with a roller can drive beads into the substrate; apply a generous, even coat with steady passes instead. Finally, do not rely on paint alone to solve structural or ventilation issues—pair Wykamol ThermalDry with extraction, background airflow and sensible heating for the best and most durable outcome.

Stop Condensation at the Source

Wykamol ThermalDry Anti Condensation Coating is engineered to tackle one of the most common causes of internal damp: warm, moisture-laden air meeting cold surfaces and dropping below its dew point. By raising the temperature of the paint film itself, the coating delays dew-point reach on walls and ceilings, providing an immediate barrier to surface wetting and the damage it triggers. Laboratory and field experience indicate it can take up to 60% longer for condensation to occur on treated surfaces compared with standard paints, delivering a measurable improvement in day-to-day comfort and finish longevity.

 

Microsphere Technology for Thermal Performance

At the core of ThermalDry is a dense matrix of hollow glass microspheres suspended in a durable styrene-acrylic binder—functioning like a microscopic thermal flask. This structure reduces thermal conductivity at the coating, reflects radiant heat back into the room and elevates the wall’s surface temperature. The result is a genuine dew-point shift that helps interiors feel warmer to the touch, curbs cyclical wetting and drying, and protects decorative finishes from premature deterioration.

 

Breathable, Water-Repellent Protection

Once cured, the coating is water-repellent to liquid moisture while remaining vapour-permeable enough for typical internal substrates, helping spaces stay drier without trapping damp within the fabric of the building. Its antibacterial formulation resists colonisation, supporting hygiene in everyday use, while the water-based, low-odour chemistry enables rapid return to service in occupied properties and integrates cleanly with standard maintenance regimes.

 

Targeted Defence for Cold Bridges and Humid Rooms

ThermalDry is purpose-built for problem areas where cold bridges and high humidity combine: exterior-facing masonry walls, concrete lintels above windows and doors, corners, ceiling perimeters and under-insulated rooms. In kitchens, bathrooms and utility spaces—where steam generation is frequent—the coating reduces bead formation on paint films and helps protect grout lines, plastered walls and previously decorated surfaces from recurrent condensation.

 

Refurbishment-Ready and Versatile Across Sectors

Designed for domestic, commercial and industrial environments alike, the coating integrates seamlessly into refurbishment programmes; once dry, it can be over-painted with standard emulsion or finished with wallpaper without sacrificing thermal performance. For landlords, housing associations, facilities managers and homeowners seeking an effective anti-condensation paint, thermal insulating paint or mould-resistant wall coating, Wykamol ThermalDry offers a practical, long-term specification choice that reduces maintenance cycles and, when paired with sensible ventilation and moisture management, helps prevent black mould while improving occupant comfort.

 

 

Signs of Condensation Dampness & Black Mould

  • Water Beading on Cold Surfaces: Visible droplets forming on painted walls, ceilings, windows reveals and lintels—especially in mornings or after cooking/showering—indicate the surface temperature has dropped below the dew point. Persistent wetting raises the risk of decorative failure, peeling paint, and microbial growth.

  • Black Mould Spots and Staining: Clusters of dark specks or velvety patches at external corners, behind furniture, around window heads and on ceiling-wall junctions are typical of condensation-related mould. Left unchecked, this can undermine air quality, aggravate asthma and allergies, and degrade plaster and finishes.

  • Musty Odours and Poor Air Quality: A stale smell in bedrooms, bathrooms or kitchens often accompanies intermittent condensation. Prolonged exposure increases health risks for vulnerable occupants and signals a need for anti-condensation measures and improved ventilation.

  • Peeling Paint, Blistering and Wallpaper Lifting: Repeated wetting weakens adhesion; paint can blister, and wallpaper seams may curl or disbond. This invites further moisture ingress, accelerates substrate deterioration and leads to costly redecorations.

  • Cold-to-Touch External Walls and Lintels: Areas that feel notably colder than the rest of the room (thermal bridges) are prime locations for dew formation. Without intervention, these cold spots drive recurring condensation and mould cycles.

  • Persistent Window Reveals and Sill Damp Patches: Damp margins around frames and sills point to surface temperature differentials and high local humidity, increasing the risk of mould colonisation and damage to sealants and finishes.

Health & Safety Recommendations

Read the label and safety data sheet in full before use. Ensure good ventilation during application and drying, particularly in kitchens, bathrooms and utility rooms where humidity is high.

Wear suitable PPE including gloves and eye protection; avoid inhalation of mist and prolonged skin contact. Do not ingest. In case of contact with eyes, rinse immediately with clean water and seek medical advice if irritation persists. Keep out of reach of children and pets. Do not apply near open flames or hot surfaces. Dispose of waste paint, contaminated wash water and empty containers in accordance with local regulations.

As a water-based, low-odour product, Wykamol ThermalDry Anti Condensation Coating is suitable for occupied properties when normal hygiene and ventilation practices are followed.

 

 

Substrate Suitability

ThermalDry is designed for interior mineral substrates such as plaster, skim coat, plasterboard, cement render and sound, previously painted walls and ceilings.

It is especially effective on exterior-facing walls, lintels, window and door reveals, ceiling perimeters and other thermal bridge areas prone to condensation damp and black mould. Where the substrate is plastic, metal or other non-masonry material, consult the manufacturer’s data for a compatible primer or contact our technical support for guidance.

The coating requires a firm, clean surface to key to; highly polished, friable or powdery surfaces must be suitably prepared or primed before use. Do not apply to surfaces exhibiting active mould or fungal growth until they have been treated.

 

 

Surface Preparation

Remove surface mould and fungus thoroughly using Wykamol MCS1 Mould Clear Solution, following the product instructions, and allow the area to dry. Strip away loose or flaking paint, degraded wallpaper, grease, oil and other contaminants that may impair adhesion.

Fill cracks and defects with a suitable Crack Filler, allow to set fully, then sand smooth. Check for existing coatings, sealers or low-energy finishes that may inhibit adhesion; lightly abrade glossy paints to provide a key and vacuum off all dust. For plastics, metals or other specialist substrates, follow the primer advice from the substrate manufacturer.

Ensure the surface is dry, clean and free from condensation at the time of application. Where persistent moisture is present, improve ventilation and heating to bring the substrate temperature at least 3°C above dew point prior to painting.

 

 

Mixing

Open the tin carefully and gently stir by hand with a flat paddle to re-disperse the hollow glass beads uniformly through the paint.

Do not use a mechanical stirrer or vigorous shaking as this may fracture the beads and reduce thermal performance. Do not thin; product is supplied ready for use.

 

 

Application Method

Apply by Brush or Roller in two full coats. Cut in edges and details first, then roll the main areas, maintaining a wet edge and working methodically to achieve an even film. Aim for consistent coverage rather than over-brushing; excessive pressure can drive the beads into the substrate and reduce insulating effect.

Allow 2–4 hours between coats at 20°C and 60% RH. Apply the second coat perpendicular to the first where practical to improve uniformity. Do not apply below 5°C or above 30°C, and avoid painting if the substrate is cold to the touch, if condensation is present, or if high humidity or poor air movement will impede drying.

In bathrooms and kitchens, keep extraction running during and after application to remove excess moisture. Spraying is not recommended due to the microbead technology and risk of equipment abrasion.

 

 

Coverage

Coverage depends on surface profile and porosity. As a guide, a 2.5 L bucket covers approximately 5 – 6.25 m² after two coats, and a 5 L bucket covers approximately 10–12 m² after two coats.

This equates to a total applied rate of roughly 0.4–0.5 L per m² for two coats (around 0.2–0.25 L per m² per coat). Highly textured or absorbent substrates will reduce coverage; plan allowances accordingly.

 

 

Drying Time

At normal room conditions (approximately 20°C, 60% RH) each coat dries in 2–4 hours. Lower temperatures, higher humidity and poor ventilation will extend drying times; higher temperatures and good airflow will shorten them.

Do not force dry with unvented heaters that add moisture to the air. Ensure the coating is touch-dry before recoating and allow the second coat to dry for 2–4 hours before finishing.

 

 

Finishing

Once the second coat has dried for 2–4 hours, ThermalDry may be over-painted with standard interior emulsions or finished with wallpaper without reducing its effectiveness. Where possible, select quality decorative finishes and adhesives appropriate to the room’s moisture load.

In rooms with chronic humidity, pair the coating with effective background ventilation and mechanical extraction to maximise anti-condensation performance. Avoid heavy sanding of the finished film; any nibs should be de-nibbed lightly to preserve the integrity of the hollow glass bead layer.

 

 

Cleaning

Clean brushes and rollers immediately after use with clean water. Do not allow washings to enter watercourses or drains; dispose of in line with local authority guidance.

Any splashes on adjacent surfaces should be wiped away promptly with a damp cloth. Once dry, residues are more difficult to remove and may require gentle mechanical action.

 

 

Other Information

ThermalDry is a water-based, styrene-acrylic, copolymer dispersion incorporating micro-technology in the form of hollow glass beads of approximately 50 μm diameter with a crush strength around 500 psi.

The coating is water-repellent when dry and produces a warmer-to-the-touch surface, delaying the onset of condensation—tests indicate it can take up to 60% longer for condensation to form compared with conventional paint. Two coats are necessary for optimum performance. Apply only between 5°C and 30°C.

The product density is approximately 0.77 kg/L. Store the container upright in a cool, dry place, protected from frost and direct sunlight, and keep the lid tightly closed when not in use.

ThermalDry is intended as part of a holistic condensation control strategy; combine with adequate heating, controlled ventilation and moisture management for best results. For unusual substrates or site conditions, or if in doubt about primers and compatibility, consult our technical services before proceeding.

Q) What is Wykamol ThermalDry Anti Condensation Coating and what problem does it solve?

A) Wykamol ThermalDry Anti Condensation Coating is a water-based, styrene-acrylic interior paint engineered to combat condensation and the black mould that follows. It contains 50 µm hollow glass beads dispersed through a durable binder, creating a low-conductivity, warm-to-the-touch film that raises surface temperature at the wall face. By lifting the surface above the dew point, ThermalDry delays the moment when airborne moisture condenses into droplets, meaning damp patches and bead formation are far less likely during daily peaks in humidity. Once dry it is water-repellent to liquid water yet practical for typical interior substrates, so rooms feel drier and finishes last longer. The coating is low odour, eco-friendly and antibacterial, which makes it suitable for occupied properties and sensitive areas. It is purpose-built for cold external walls, lintels and other thermal bridges in homes and commercial buildings where persistent condensation undermines decoration and indoor air quality.

 

Q) How does Wykamol ThermalDry Anti Condensation Coating work to reduce condensation and mould?

A) Wykamol ThermalDry Anti Condensation Coating works by altering the thermal and moisture behaviour at the paint film. The hollow glass beads act like microscopic thermal flasks, reducing heat loss through the coating and reflecting radiant warmth back into the room, which raises the measured surface temperature. When the surface stays warmer, the dew point is effectively shifted away from the wall face, so humid air must cool further before water condenses. Laboratory and field experience indicate treated surfaces can take up to 60% longer to develop visible condensation compared with standard emulsions under comparable conditions. Because the dry film is water-repellent, occasional moisture beads do not soak in, which helps the area dry quickly and discourages fungal colonisation. The antibacterial formulation adds an extra layer of hygiene by resisting microbial growth on the paint film. Together, these effects cut the wetting–drying cycles that drive black mould and decorative failure.

 

Q) Where should Wykamol ThermalDry Anti Condensation Coating be used for best results?

A) Wykamol ThermalDry Anti Condensation Coating is most effective on interior surfaces that run cold or see frequent humidity. Priorities include exterior-facing masonry walls, window and door reveals, concrete or steel lintels and ceiling perimeters where thermal bridging is common. Kitchens, bathrooms and utility rooms benefit due to repeated steam generation, as do north-facing or under-heated bedrooms that struggle to stay above dew point overnight. In social housing, HMOs and rental portfolios, it offers a quick-return upgrade that helps reduce mould complaints and redecoration cycles. Offices, welfare areas and plant-adjacent rooms with intermittent heating also gain more stable surface conditions. The coating integrates neatly into refurbishment programmes because it applies like a standard emulsion, allows rapid return to service, and provides a warmer, water-shedding surface that extends the life of subsequent decorative finishes.

 

Q) Which substrates are suitable for Wykamol ThermalDry Anti Condensation Coating and which need special attention?

A) Wykamol ThermalDry Anti Condensation Coating is intended for interior mineral surfaces such as plaster, skim coat, plasterboard, cement render and sound, previously painted walls and ceilings. It adheres well when the base is clean, firm and dry, making it ideal for typical domestic and commercial interiors. Highly polished, friable or chalky surfaces require appropriate preparation or priming to provide a reliable key. Plastics, metals and other non-masonry materials may need a compatible primer—check the substrate manufacturer’s guidance or seek technical advice before proceeding. Do not apply over active mould; treat microbial growth first, allow to dry, then paint. Avoid surfaces with ongoing liquid water ingress or structural dampness that would defeat any anti-condensation coating; those issues should be resolved at source. When in doubt, a small adhesion and appearance trial is sensible before full application.

 

Q) Can Wykamol ThermalDry Anti Condensation Coating be over-painted or wallpapered without losing its effect?

A) Yes. Wykamol ThermalDry Anti Condensation Coating is designed to accept conventional decorative finishes without compromising its thermal and anti-condensation function. Once the second coat has dried, you can apply standard interior emulsions to achieve your chosen colour scheme, or hang wallpaper using suitable adhesives for the room’s moisture load. The hollow glass bead matrix remains embedded within the film, so over-coating does not negate the dew-point shift or warm-touch benefits. Where heavy wallcoverings are planned, ensure joints are well bonded and surfaces are smooth to avoid localised cold spots at lapped edges. In higher-humidity rooms, pair the coating with reliable extraction and background ventilation so the whole system—paint plus environment—works together. If future colour changes are expected, ThermalDry provides a long-term base layer that continues to protect against condensation cycles beneath new finishes.

 

Q) How does Wykamol ThermalDry Anti Condensation Coating compare with normal emulsion paint?

A) Compared with conventional emulsions, Wykamol ThermalDry Anti Condensation Coating offers measurable thermal and moisture-management advantages at the coating interface. The micro-spheres reduce thermal conductivity and reflect radiant heat, so the film runs warmer and feels less clammy to the touch on cold days. Treated areas typically take much longer to reach visible condensation, especially during spikes after showering or cooking, which helps keep surfaces drier over 24-hour cycles. The dry film’s water-repellency means occasional moisture beads are less likely to soak in and cause blistering, peeling or staining. Ordinary emulsions lack this combination of micro-insulation and water-shedding, so they tend to wet and dry repeatedly, inviting mould and premature decorative failure. Because ThermalDry is water-based and low odour, it applies like a quality emulsion, yet it delivers a functional upgrade that extends maintenance intervals and improves perceived comfort in problem rooms.

 

Q) What coverage should I expect from Wykamol ThermalDry Anti Condensation Coating?

A) Coverage depends on surface texture and porosity, but practical planning figures are well established. A 2.5 litre pack of Wykamol ThermalDry Anti Condensation Coating typically covers about 5–6.25 m² after two full coats, while a 5 litre pack covers roughly 10–12 m² after two coats. That equates to an overall application rate in the region of 0.4–0.5 litres per square metre for the full system, or 0.2–0.25 litres per square metre per coat. Textured finishes, open-grained plaster or previously degraded areas will consume more material, so include sensible allowances when ordering. Aim for a consistent, even film rather than chasing maximum spread, because uniform bead distribution underpins the thermal effect. If you are treating only thermal bridges such as lintels and reveals, measure those lengths and widths carefully; spot treatments should feather into adjacent areas to avoid visible banding.

 

Q) How should I prepare surfaces before applying Wykamol ThermalDry Anti Condensation Coating?

A) Proper preparation ensures long-term adhesion and full thermal benefit. Begin by removing all visible mould and mildew with an appropriate biocidal cleaner such as Wykamol MCS1 Mould Clear Solution, following label instructions, then allow the surface to dry. Scrape away loose or flaking paint, lift failing wallpaper, and clean off grease or contamination that would interfere with bonding. Fill cracks and minor defects, allow to set and sand smooth, then lightly abrade glossy paints to create a key. Vacuum or wipe down to remove dust. Ensure the substrate is dry and at least a few degrees above dew point at the time of painting; if surfaces are cold to the touch or showing condensation, improve heating and ventilation first. For plastics, metals or other low-energy surfaces, apply a suitable primer as specified by the substrate manufacturer before using ThermalDry.

 

Q) Do I need to stir Wykamol ThermalDry Anti Condensation Coating and can it be thinned?

A) Wykamol ThermalDry Anti Condensation Coating should be gently stirred by hand with a flat paddle before use to re-disperse the hollow glass beads uniformly throughout the paint. Avoid mechanical mixers and vigorous shaking, which can fracture the beads and diminish the insulating effect. The product is supplied ready for use and should not be thinned unless the manufacturer has given specific guidance for unusual conditions. Maintaining the designed solids content helps you achieve the correct dry film thickness and bead packing, both of which are central to performance. If the material has been stored in a cool place, allow it to come to room temperature before stirring so the viscosity is consistent. Reseal the lid between coats and during breaks to prevent skinning and moisture uptake, which can affect application feel and coverage.

 

Q) What is the recommended application method for Wykamol ThermalDry Anti Condensation Coating?

A) Apply Wykamol ThermalDry Anti Condensation Coating by brush or roller in two full coats for a uniform, functional film. Cut in edges and details with a brush, then roll the main fields, working methodically and maintaining a wet edge. Use light, even pressure; over-brushing or pressing too hard can drive beads into the substrate and reduce the micro-insulation at the surface. Where practical, apply the second coat perpendicular to the first to promote even coverage and bead distribution. Spraying is not recommended because the bead technology can abrade equipment and may not lay down the optimal film structure. Keep extraction running in kitchens and bathrooms during and after painting to remove moisture and aid drying. Avoid painting if condensation is present or the substrate feels cold; the finish should be formed under stable, room-like conditions for best results.

 

Q) How long does Wykamol ThermalDry Anti Condensation Coating take to dry and when can I recoat?

A) In typical room conditions around 20°C and 60% relative humidity, each coat of Wykamol ThermalDry Anti Condensation Coating dries within approximately 2–4 hours. You can recoat as soon as the first application is touch-dry and firm, usually within that window. Cooler temperatures, higher humidity and poor air movement will slow the process, while warmer, well-ventilated rooms will shorten it. Do not force-dry with unvented heaters that add moisture to the air, as this can prolong drying and compromise appearance. After the second coat, allow another 2–4 hours before over-painting with standard emulsion or proceeding with wallpaper. As with any functional coating, final performance depends on achieving the correct film build, so resist the temptation to rush recoats on marginally dry surfaces.

 

Q) What environmental conditions are best for applying Wykamol ThermalDry Anti Condensation Coating?

A) Aim to apply Wykamol ThermalDry Anti Condensation Coating between 5°C and 30°C with moderate humidity and good air movement. The substrate should be dry and at least about 3°C above dew point to prevent moisture condensing on the film during application. In bathrooms and kitchens, run extraction continuously while painting and for several hours after to purge humidity. On cold days, gently pre-warm rooms so walls and ceilings are comfortably above the condensation threshold before you start. Avoid direct heat on the surface, hot pipes or strong sunlight that could skin the film too quickly and disrupt bead distribution. If conditions are variable across a property, schedule rooms so you always work in stable areas, returning to trickier spaces when temperature and ventilation can be controlled.

 

Q) What practical tips will improve results with Wykamol ThermalDry Anti Condensation Coating?

A) Success with Wykamol ThermalDry Anti Condensation Coating rests on even bead distribution and sound site practice. Stir gently before each session, decant manageable amounts into a scuttle, and reseal the main container promptly. Use medium-nap rollers that hold sufficient paint without excessive pressure, and focus on steady, overlapping passes to lay down a consistent film. Treat mould first and address moisture sources; pairing the coating with working extraction fans and background ventilation dramatically improves long-term outcomes. Feather treatments beyond the obvious cold patch to avoid a visual edge and to ensure continuity of thermal effect. After drying, avoid heavy sanding of the finished film; if needed, de-nib gently so you preserve the micro-sphere layer. Finally, educate occupants to ventilate during high-humidity activities—paint can delay condensation, but good habits keep conditions within its design envelope.

 

Q) Are there limitations to what Wykamol ThermalDry Anti Condensation Coating can achieve?

A) Wykamol ThermalDry Anti Condensation Coating is a powerful tool against surface condensation, but it is not a cure-all for moisture problems. It cannot compensate for structural dampness, liquid water ingress, or significant thermal defects that keep surfaces persistently cold. It is not intended for exterior use or for continuous wet areas inside shower enclosures where direct water impact is severe. Spraying is discouraged due to the risk of damaging the micro-beads and the difficulty of controlling film structure. The product relies on correct preparation and adequate film build; very thin or patchy application will reduce its effect. It should not be applied over active mould or to contaminated, friable or glossy surfaces without proper treatment and keying. Best performance is achieved as part of a wider strategy that includes sensible heating, moisture control and ventilation upgrades.

 

Q) Is Wykamol ThermalDry Anti Condensation Coating safe to use in occupied homes and how should I handle it?

A) Wykamol ThermalDry Anti Condensation Coating is water-based, low odour and suitable for use in occupied properties when normal hygiene and ventilation practices are followed. Provide adequate fresh air during application and drying, particularly in smaller bathrooms and kitchens, and avoid inhaling mists. Wear suitable gloves and eye protection, and wash hands after use. In the event of eye contact, rinse immediately with clean water and seek medical advice if irritation persists. Keep the product out of reach of children and pets, and do not ingest. Dispose of waste paint, wash water and empty containers responsibly in accordance with local regulations. The coating’s antibacterial nature supports better hygiene on the finished surface, but standard cleaning and ventilation remain essential to maintaining healthy indoor conditions.

 

Q) What technical data define Wykamol ThermalDry Anti Condensation Coating’s performance?

A) Wykamol ThermalDry Anti Condensation Coating is a styrene-acrylic copolymer dispersion loaded with approximately 50 µm hollow glass beads that have a crush strength around 500 psi, ensuring they survive application and service. The product density is roughly 0.77 kg per litre, reflecting the micro-sphere content and contributing to the warm-touch feel at the surface. Once fully dry, the film is water-repellent to liquid water yet practical for typical interior substrates, supporting a drier surface profile during humidity spikes. Under comparable conditions, treated areas can take up to 60% longer to show visible condensation than standard paint, indicating a meaningful dew-point margin. Recommended application temperature is 5–30°C with two full coats for performance, at a total usage of around 0.4–0.5 litres per square metre. These characteristics combine to produce a durable, functional finish that integrates seamlessly with standard decorative systems.

 

Q) How long will the benefits of Wykamol ThermalDry Anti Condensation Coating last and how should I maintain it?

A) The benefits of Wykamol ThermalDry Anti Condensation Coating are inherent to the dry film and persist for the life of the coating when applied at the correct thickness and used under normal service conditions. Because it reduces wetting cycles and sheds liquid water, it also helps protect subsequent decorative finishes, extending the time between redecorations. Routine maintenance is simple: clean with a lightly dampened cloth and mild detergent as needed, avoiding aggressive scouring that could thin the functional layer. If redecorating, over-paint with quality interior emulsion; the micro-insulation remains active beneath. Longevity is enhanced when the broader environment supports it—use extraction in wet rooms, manage indoor humidity and avoid blocking airflow behind large furniture. When these measures accompany the coating, users typically report more stable comfort and fewer mould-related call-outs over the long term.

 

Q) Can Wykamol ThermalDry Anti Condensation Coating be used in commercial or light industrial settings?

A) Yes. Wykamol ThermalDry Anti Condensation Coating is suitable for commercial and light industrial interiors where intermittent heating, process humidity or cold bridges drive recurring condensation. Offices, welfare areas, plant rooms, corridors and ancillary spaces benefit from the warmer surface temperature and water-shedding film, which reduces staining and maintenance disruptions. Because the coating is low odour and water-based, it can be applied with minimal downtime and quick return to service. In facilities management programmes, it provides a targeted, cost-effective upgrade for known cold-spot zones without the thickness or complexity of internal insulation boards. When specifying, ensure substrate preparation standards are met across varied finishes, and pair the coating with sensible ventilation policies to keep conditions within range. Its compatibility with over-painting allows future colour changes without losing functional performance.

 

Q) How should Wykamol ThermalDry Anti Condensation Coating be stored and handled before application?

A) Store Wykamol ThermalDry Anti Condensation Coating upright in a cool, dry place, protected from frost and direct sunlight to preserve viscosity and bead integrity. Keep the lid tightly closed when not in use to prevent skinning and contamination. If the product has been chilled, allow it to reach room temperature before stirring and application so it rolls out evenly. Do not leave the open can in steamy rooms for long periods; decant what you need into a tray and reseal the main container. Avoid stacking heavy items on the lid, which could compromise the seal. Observe shelf-life guidance on the label and rotate stock so older containers are used first. Good storage practice ensures the micro-technology is intact when you are ready to paint, delivering the expected anti-condensation performance.

 

Q) What common mistakes should be avoided when using Wykamol ThermalDry Anti Condensation Coating?

A) The most frequent pitfalls are inadequate preparation, poor environmental control and over-working the film. Skipping mould treatment or painting over damp, glossy or dusty surfaces undermines adhesion and performance, so complete those steps thoroughly. Painting onto a surface at or below dew point can trap moisture or cause early bloom; warm and ventilate the room so the substrate is safely above dew point before starting. Do not use mechanical mixers or aggressive stirring that could crush the beads, and avoid thinning unless instructed, as this reduces film build and thermal benefit. Heavy pressure with a roller can drive beads into the substrate; apply a generous, even coat with steady passes instead. Finally, do not rely on paint alone to solve structural or ventilation issues—pair Wykamol ThermalDry with extraction, background airflow and sensible heating for the best and most durable outcome.
