Advanced Anti Condensation Thermal Coating For Problem Walls

ACS Hydrobar AntiCon TBC is an advanced anti condensation thermal paint formulated to address surface condensation where standard emulsions repeatedly fail. Combining modern polymer chemistry with carefully selected mineral fillers, it manages surface temperature at the paint to air interface so that internal moisture is less likely to condense. Conventional coatings sit directly on cold substrates, allowing vapour to condense whenever the surface drops below dew point. Hydrobar AntiCon TBC incorporates an active mineral system that reduces water uptake and provides a genuine insulating layer, helping to keep the surface a few degrees warmer than untreated substrates. This delay in condensation onset gives normal heating and ventilation time to disperse moisture before it turns into water on walls or ceilings.

 

Low Odour, Moisture Resistant Finish For Occupied Interiors

The formulation is based on a waterborne acrylated vinyl acetate binder combined with non toxic pigments and natural earth minerals, resulting in a low odour, easy to apply coating suitable for occupied buildings. Once cured, the film is tough, slightly elastic and resistant to intermittent moisture from activities such as cooking and showering. Its fine textured matt finish helps to disguise minor surface imperfections and softens reflected light, creating a clean, understated look appropriate for both domestic and commercial interiors. Because the texture is subtle rather than coarse, ACS Hydrobar AntiCon TBC can be used in most standard living and working spaces without appearing industrial.

 

Primer Or Finish System For Flexible Condensation Control

ACS Hydrobar AntiCon TBC has been developed to function effectively in two complementary roles. Used as a primer, it can be applied directly to the prepared substrate to form a thermally efficient basecoat beneath a suitable decorative topcoat. In this configuration it raises surface temperature, improves resistance to condensation and reduces the risk of cold bridge staining beneath the final colour coat. Alternatively, it can be specified as a finish system in its own right, providing a durable, fine textured matt surface that actively resists condensation without additional paint layers. This flexibility allows specifiers and contractors to tailor the build up to the appearance, cleaning and performance requirements of each project while maintaining robust condensation control.

 

Biocidal Protection For Demanding Humid Environments

The coating also contains an in can biocide that protects the dry film from fungal growth, offering added reassurance in areas prone to damp and intermittent high humidity. When used as part of a sensible condensation management strategy, alongside appropriate ventilation, background heating and good housekeeping, ACS Hydrobar AntiCon TBC helps to extend repainting intervals, reduce spoilage of finishes and contents, and improve perceived comfort in challenging environments. Typical applications include domestic kitchens and bathrooms, hospitals, schools, food and drink production areas, animal housing, offices and factories where surface condensation has been difficult to control with standard emulsion paints.

Health & Safety Recommendations

ACS Hydrobar AntiCon TBC is a specialist anti-condensation thermal paint, so it should be handled with the same care as any professional coating. Always read the product label and safety data sheet in full before starting work. Ensure good ventilation during application and drying, particularly in small bathrooms, shower rooms or plant areas where humidity may already be high. Avoid breathing spray mist if airless or conventional spray is used; in such cases, suitable respiratory protection may be required.

Wear appropriate personal protective equipment, including gloves, eye protection and suitable work clothing to avoid skin and eye contact. Wash splashes from skin promptly with soap and water and rinse eyes immediately with clean water if accidental contact occurs. Do not eat, drink or smoke while using the product, and keep containers tightly closed and out of the reach of children when not in use. Any residual mould or fungal contamination should be treated with ACS Mould Wash Concentrate in line with the manufacturer’s safety advice, since Hydrobar AntiCon TBC is designed to prevent recurrence rather than to act as a primary surface steriliser.

 

 

Substrate Suitability

ACS Hydrobar AntiCon TBC is suitable for use on a wide variety of interior substrates commonly found in domestic, commercial and industrial buildings. Typical backgrounds include previously painted plaster, cementitious surfaces, brickwork, blockwork, concrete soffits, drylined partitions and sound textured finishes such as Artex or similar decorative plasters. It may also be applied over primed non-ferrous and ferrous metals, subject to correct priming, and over compatible sealers on porous masonry.

In bathrooms, shower rooms, food preparation areas and other spaces subject to high humidity, Hydrobar AntiCon TBC is particularly effective when applied over a suitable acrylic surface sealer that consolidates porous substrates and reduces suction. On highly absorbent or friable backgrounds, a compatible masonry sealer should be used first to avoid excessive soak-in and to help the anti-condensation coating build its required film thickness. The product is intended primarily for internal ceilings and upper wall areas; use on walls subject to frequent impact or aggressive cleaning should be considered carefully, as this is a relatively hard but not heavy-duty scrubbable finish.

 

 

Surface Preparation

Careful surface preparation is essential for long-term performance of any anti-condensation paint. All surfaces must be clean, dry and free from dust, oil, grease, wax, loose or flaking coatings and any other contaminants that could impair adhesion. Remove failing paint or wallpaper back to a firm, sound edge and make good cracks, holes and surface imperfections with a suitable interior filler or decorators’ caulk. Once cured, sand these areas to a smooth, feathered profile and remove all sanding dust.

Glossy or hard oil-based finishes should be lightly abraded with aluminium-oxide paper to provide a key, then washed with a mild detergent solution, rinsed thoroughly with clean water and allowed to dry. Once clean and dull, they should be primed with a good quality high-adhesion acrylic primer in accordance with the manufacturer’s instructions before applying Hydrobar AntiCon TBC.

Bare ferrous metals must be free from rust and millscale, ideally prepared to at least an SA 2.5-equivalent standard. Apply one full coat of a suitable zinc phosphate or similar anti-corrosive metal primer and allow it to dry thoroughly, inspecting for flash rusting; if any corrosion reappears, abrade and spot prime again before overcoating. Non-ferrous metals should be primed with a compatible metal primer as recommended by the primer manufacturer.

Porous masonry and new plaster should be allowed to dry fully and be free from surface laitance. In bathrooms, shower rooms and areas of high humidity, apply one coat of a suitable acrylic surface sealer and allow to dry. In other less critical areas, apply one or two coats of a compatible acrylic masonry sealer, depending on porosity, to bind loose surface particles and balance suction. This sealer approach is also appropriate for unpainted textured finishes such as Artex so that Hydrobar AntiCon TBC can form a continuous thermal film.

Any existing mould growth must be eradicated before painting. Treat affected areas with ACS Mould Wash Concentrate diluted with clean water, following the manufacturer’s dwell time and rinsing instructions. Allow surfaces to dry thoroughly after treatment. Hydrobar AntiCon TBC contains an in-film preservative to help resist future mould colonisation, but it must always be applied to clean, decontaminated surfaces for best results.

 

 

Application Method

ACS Hydrobar AntiCon TBC is supplied ready for use and should not be thinned. Before opening, ensure the container has been stored in a frost-free environment at an appropriate temperature. Gently stir the paint with a clean stirrer to redisperse any settled solids, taking care not to entrain excessive air.

The coating can be applied by brush, medium-nap roller or spray. For brush and roller work, lightly dampen the tool with clean water, remove excess, then load generously and apply a liberal, even coat. Lay off in a consistent direction to achieve a uniform texture and avoid over-spreading, as this reduces the film build that provides the anti-condensation performance. Always work to a wet edge, completing one panel or section at a time to avoid visible lap marks, particularly on ceilings and large uninterrupted walls.

For spray application, consult your spray equipment supplier for tip size and pressure guidance suitable for medium-build waterborne coatings. Maintain a consistent gun distance and overlap passes by around one third to ensure uniform coverage. Mask off adjacent surfaces, fixtures and fittings, and protect floors with suitable sheeting. Regardless of application method, avoid working over areas that have begun to dry, as this can create patchiness and uneven texture.

A minimum of two full coats of Hydrobar AntiCon TBC is required to achieve the correct combined film thickness and thermal performance; three coats are recommended in areas of very high humidity or persistent condensation. Allow the first coat to dry fully before applying subsequent coats.

Coverage

Typical coverage for ACS Hydrobar AntiCon TBC is 4m² - 6m² per litre per coat, depending on surface profile and porosity. Two to three coats are recommended. On smooth, well-sealed surfaces, expect coverage nearer the upper end of the range, while rough or absorbent substrates will tend towards the lower end.

As a practical guide, a 2.5L container will typically cover approximately 5m² - 7.5m² with two coats, or around 3.3m² - 5m² with three coats. A 5L container will usually cover roughly 10–15m² with two coats, or about 6.7m² - 10m² with three coats.

These figures provide an indicative finished area for planning purposes; exact usage will depend on application technique, surface condition and the desired texture. Always ensure sufficient material is available to complete all planned coats on a given area without interruption.

 

 

Drying Time

At around 20°C with good ventilation and moderate humidity, Hydrobar AntiCon TBC is typically touch-dry in about one hour. The coating will usually reach a hard dry condition within 2–3 hours, allowing light handling or masking removal. Recoating can normally take place after 2–3 hours, provided the underlying film is dry and firm to the touch.

Full cure and readiness for return to service, particularly in high humidity environments such as bathrooms or shower rooms, is achieved after approximately 24 hours under standard conditions. Drying and curing times are strongly influenced by temperature, relative humidity and air movement. Cooler conditions, high humidity or poor ventilation will extend these times, so always allow additional drying in marginal conditions before exposing the surface to condensation or regular use.

 

 

Cleaning

Hydrobar AntiCon TBC is a waterborne coating, so tools and equipment should be cleaned as soon as possible after use with clean water. Rinse brushes and rollers thoroughly until the water runs clear and then allow them to dry naturally. Avoid washing large quantities of waste paint into drains; instead, wipe excess material from tools onto absorbent paper and dispose of this in line with local regulations.

Once cured, the coating can be cleaned periodically to maintain appearance. For routine surface cleaning, use warm water with a mild detergent or a diluted specialist mould-wash cleaner recommended for use with anti-mould and anti-condensation coatings. Avoid aggressive chemical cleaners, bleach solutions such as strong sodium hypochlorite, or abrasive pads, as these may damage the film and compromise both the appearance and the in-film biocide protection. Always test any cleaning regime on a small, inconspicuous area first.

 

 

Limitations

ACS Hydrobar AntiCon TBC is designed as an interior anti-condensation and thermal bridge reduction coating. It is not normally recommended for exterior use and should not be used where the surface will be exposed to persistent weathering or direct sunlight. The product must not be applied directly to bare ferrous metal; such surfaces require preparation and priming with a suitable zinc phosphate or comparable anti-corrosive primer prior to sealing and overcoating.

Application conditions are critical. Do not apply the coating if the relative humidity exceeds 85% or if the substrate temperature is less than 3°C above the prevailing dewpoint, as this may result in condensation forming on the wet film, leading to defects. The product should not be thinned, as dilution may reduce its insulating properties and the level of in-film protection. Hydrobar AntiCon TBC is relatively hard once cured but is not intended for substrates subject to heavy wear, frequent scrubbing or mechanical abuse; in such areas, consider complementary protective finishes.

It is important to understand that Hydrobar AntiCon TBC delays the onset of condensation by helping the treated surface remain warmer relative to the surrounding air. If the surface cools to at or below the dewpoint because of severe conditions or inadequate overall heating and ventilation, condensation may still occur. The coating should therefore be viewed as part of a broader strategy that also addresses heating, ventilation and moisture load within the building.

 

 

Other Information

For optimal long-term performance, Hydrobar AntiCon TBC must be stored and used correctly. Store containers in dry, frost-free conditions, ideally between 5°C and 25°C, and keep the lid tightly closed when not in use. Do not allow the product to freeze. If stored for extended periods, stir thoroughly before use to ensure uniform consistency.

Hydrobar AntiCon TBC may be over-painted with ACS Anti Mould & Anti Bacterial Paint Emulsion where enhanced antimicrobial performance is required, creating a combined system that addresses both condensation and mould spore growth. It may also be overcoated with conventional decorative paints, provided a small trial area is tested first for compatibility and adhesion. However, if a conventional topcoat is used, the full moisture-managing and biocidal benefits of Hydrobar AntiCon TBC at the surface may be reduced.

The coating should be fully dry before the area is returned to normal service. In shower rooms and similar spaces, it is good practice to avoid using showers or generating heavy steam for at least 24 hours after final application. Beyond coating works, building owners should implement basic condensation-control measures such as maintaining some background heat, ensuring adequate natural or mechanical ventilation, venting tumble driers externally, using lids on pans during cooking and closing doors to wet rooms while moisture is being generated.

When combined with such good practice, ACS Hydrobar AntiCon TBC provides an effective, durable tool for managing condensation risk on ceilings and walls, helping to protect surfaces from recurrent dampness and the appearance of mould in both residential and commercial properties.

Q) What is ACS Hydrobar AntiCon TBC – Anti Condensation Thermal Paint and what is it designed to do?

A) ACS Hydrobar AntiCon TBC – Anti Condensation Thermal Paint is a single-pack, waterborne coating developed to reduce surface condensation on internal walls and ceilings in homes, commercial buildings and industrial premises. It uses advanced acrylated vinyl acetate resins combined with natural earth minerals and non-toxic pigments to form a fine textured, insulating matt film. This film helps keep surfaces warmer and drier for longer than standard emulsion, delaying the point at which moisture in the air condenses. ACS Hydrobar AntiCon TBC can be used as a thermal primer or as a durable finish coat, helping to manage condensation, discourage mould and protect sensitive areas.

 

Q) How does ACS Hydrobar AntiCon TBC actually reduce condensation on walls and ceilings?

A) ACS Hydrobar AntiCon TBC reduces condensation by improving the thermal behaviour of the painted surface. Standard emulsions sit directly on cold substrates, so when room air reaches dew point, moisture condenses quickly on the paint film. Hydrobar AntiCon TBC incorporates an active mineral system that lowers water uptake and adds genuine insulation, keeping the surface temperature a few degrees higher than untreated backgrounds. This delay gives normal heating and ventilation more time to remove moisture from the air, reducing visible condensation, drips and streaks. The slightly insulating film also helps cold-bridge areas, cutting the sharp temperature differences that typically generate persistent wet patches.

 

Q) Where is ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint most suitable for use?

A) ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is ideal wherever surface condensation has been a persistent problem. Typical domestic areas include bathroom and shower ceilings, kitchen and utility walls, cold external walls in bedrooms and living rooms, and vulnerable corners or window reveals. In commercial and institutional settings it suits corridors, stairwells, welfare areas, plant rooms, changing rooms, clinics, hospital circulation areas, canteens and staff kitchens. In industrial and food-related environments it is often used on ceilings and soffits above production lines or packing areas where warm, humid air condenses on cold surfaces and may drip onto stock, equipment or finishes.

 

Q) Can ACS Hydrobar AntiCon TBC be used as both a thermal primer and a finished topcoat?

A) Yes, ACS Hydrobar AntiCon TBC has been designed to work flexibly either as a dedicated thermal primer or as a fine textured finish in its own right. As a primer, it is applied directly to the prepared substrate to build an insulating, condensation-resistant base layer, which can then be overcoated with a compatible decorative topcoat if a particular colour or sheen is required. As a finish system, two to three coats of ACS Hydrobar AntiCon TBC provide a durable, fine textured matt surface that actively resists condensation without further overcoating. This dual role allows specifiers to balance performance, aesthetics and cleaning requirements on each project.

 

Q) On which substrates is ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint suitable to apply?

A) ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is suitable for most internal mineral and previously painted surfaces that are sound, clean and dry. This includes plaster, plasterboard, cement renders, brickwork, blockwork, concrete soffits, drylined partitions and many textured finishes such as Artex once sealed. It can also be applied over correctly primed ferrous and non-ferrous metals using appropriate metal primers, and over acrylic sealers on porous masonry. In high humidity locations, sealing very absorbent surfaces beforehand improves film build and performance. It is intended primarily for ceilings and wall areas susceptible to condensation, rather than for floors or heavy-duty impact zones.

 

Q) How should surfaces be prepared before applying ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint?

A) Preparation for ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint follows good trade practice but needs extra care in problem areas. Remove all loose or flaking paint, failing coatings and wallpaper, then fill cracks and defects with a compatible filler and sand smooth. Wash down greasy or contaminated surfaces with a mild detergent, rinse and allow to dry. Glossy or oil-based coatings should be abraded to give a key and primed with a high-adhesion acrylic primer. Porous masonry and new plaster benefit from an acrylic surface sealer or masonry sealer to control suction. Any existing mould must be treated with ACS Mould Wash Concentrate and fully removed before painting.

 

Q) What is the correct application method for ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint?

A) ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is supplied ready to use and should be stirred thoroughly before application without thinning. It can be applied by brush, medium-nap roller or spray. When brushing or rolling, load the tool generously and apply a liberal, even coat, laying off in one direction to achieve a uniform fine texture and avoiding over-spreading, as film thickness is critical for thermal performance. Always maintain a wet edge and complete each wall or ceiling section in one pass to prevent lap marks. For spray use, select equipment suitable for medium-build waterborne coatings and apply cross passes for even coverage, masking adjacent surfaces carefully.

 

Q) How much coverage can I expect from ACS Hydrobar AntiCon TBC and how many coats are needed?

A) ACS Hydrobar AntiCon TBC typically covers around 4–6m² per litre per coat, depending on surface texture and porosity. Because the anti condensation effect depends on a sufficient insulating film thickness, a minimum of two full coats is required, and three coats are recommended in very high humidity or severe condensation areas. As a practical guide, a 2.5 litre tin will generally provide two coats over about 5–7.5m², while a 5 litre tin will cover roughly 10–15m² with two coats. Rough or highly absorbent backgrounds may reduce these figures. It is important to ensure enough material is available to complete all planned coats on each area.

 

Q) What are the drying and curing times for ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint?

A) In typical indoor conditions of around 20°C with reasonable ventilation, ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is usually touch dry in about one hour and hard dry within two to three hours. Recoating is normally possible after two to three hours, provided the first coat is dry and firm. Full cure, when the coating achieves its designed mechanical strength and condensation resistance, is reached after roughly 24 hours. Cooler temperatures, high humidity or poor air movement extend these times, so bathrooms, shower rooms and plant areas may need longer before being returned to heavy use. Avoid exposing freshly painted surfaces to heavy condensation during early curing.

 

Q) Can ACS Hydrobar AntiCon TBC be overcoated with other paints such as standard emulsions or anti mould products?

A) ACS Hydrobar AntiCon TBC can be overcoated with compatible waterborne decorative paints once fully dry, although doing so will interpose another film between the room environment and the thermal coating. In many cases it is best left exposed as the finish. Where enhanced mould control is required, ACS Hydrobar AntiCon TBC may be overpainted with ACS Anti Mould & Anti Bacterial Paint Emulsion, creating a combined system that tackles both condensation and surface microbiological growth. If standard emulsions are used, a test area should always be carried out first to confirm adhesion and appearance, and to ensure the decorative coat does not compromise the underlying performance.

 

Q) What are the main advantages of ACS Hydrobar AntiCon TBC over normal emulsion paint?

A) ACS Hydrobar AntiCon TBC offers several advantages over normal emulsion paints in condensation-prone environments. Its mineral-loaded formulation provides genuine thermal resistance at the surface, helping to keep walls and ceilings warmer and reducing condensation and drips. The active mineral system also limits water uptake into the film, so damp patches dry more quickly. The coating’s fine textured matt finish disguises minor defects better than many smooth emulsions, while the tough, slightly elastic film resists microcracking under normal movement. In addition, ACS Hydrobar AntiCon TBC contains an in-film preservative to help protect against fungal attack, making it more robust in humid areas than standard decorative coatings.

 

Q) Are there any limitations or situations where ACS Hydrobar AntiCon TBC should not be used?

A) ACS Hydrobar AntiCon TBC is designed for interior use and is not generally suitable for exterior façades or areas subject to continuous direct weathering or strong UV exposure. It should not be applied directly to bare ferrous metal without prior priming, nor to floors or surfaces exposed to heavy mechanical wear or frequent harsh scrubbing. Application should be avoided where relative humidity exceeds about 85% or where the substrate temperature is close to dew point, as condensation on the wet film can cause defects. The product must not be thinned, and it should not be used as a substitute for correcting structural damp, leaks or serious moisture ingress.

 

Q) Is ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint safe to use in occupied homes and sensitive environments?

A) ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is waterborne, low odour and based on acrylated vinyl acetate resins with non-toxic pigments and natural earth minerals, making it suitable for use in occupied homes, offices, schools and many sensitive environments. As with any professional coating, standard precautions apply: ensure good ventilation during application and drying, avoid skin and eye contact, and wear suitable gloves, eye protection and work clothing. Once fully dry, the coating forms an inert, stable film. The in-can biocide is present to protect the wet product and dried film from fungal attack and is used within regulatory limits, provided the product is used strictly as directed.

 

Q) How should ACS Hydrobar AntiCon TBC coated surfaces be cleaned and maintained?

A) Once ACS Hydrobar AntiCon TBC has fully cured, surfaces can be cleaned periodically to maintain appearance and hygiene. For routine cleaning, use warm water with a mild detergent and a soft cloth or sponge, working gently to avoid damaging the fine textured surface. Avoid aggressive chemical cleaners, strong bleach solutions and abrasive pads, as these can erode or burnish the film and potentially reduce its functional performance. Always test any new cleaning method on a small, inconspicuous area first. Good housekeeping, including prompt wiping of occasional splashes and controlling excess moisture, will help the anti condensation coating perform at its best over the long term.

 

Q) How does ACS Hydrobar AntiCon TBC fit into a wider strategy for controlling condensation and mould?

A) ACS Hydrobar AntiCon TBC should be viewed as a key part of a broader condensation and mould control strategy rather than a complete solution on its own. By raising surface temperatures and reducing water uptake, it significantly lowers the likelihood and severity of condensation on problem ceilings and walls. However, building owners and occupants should still address underlying issues such as inadequate ventilation, intermittent or insufficient heating, high internal moisture loads and structural defects. Using ACS Hydrobar AntiCon TBC alongside sensible measures like extractor fans, trickle vents, background heating and prompt repair of leaks provides a more reliable, long-term defence against condensation damage and mould formation.

Health & Safety Recommendations

ACS Hydrobar AntiCon TBC is a specialist anti-condensation thermal paint, so it should be handled with the same care as any professional coating. Always read the product label and safety data sheet in full before starting work. Ensure good ventilation during application and drying, particularly in small bathrooms, shower rooms or plant areas where humidity may already be high. Avoid breathing spray mist if airless or conventional spray is used; in such cases, suitable respiratory protection may be required.

Wear appropriate personal protective equipment, including gloves, eye protection and suitable work clothing to avoid skin and eye contact. Wash splashes from skin promptly with soap and water and rinse eyes immediately with clean water if accidental contact occurs. Do not eat, drink or smoke while using the product, and keep containers tightly closed and out of the reach of children when not in use. Any residual mould or fungal contamination should be treated with ACS Mould Wash Concentrate in line with the manufacturer’s safety advice, since Hydrobar AntiCon TBC is designed to prevent recurrence rather than to act as a primary surface steriliser.

 

 

Substrate Suitability

ACS Hydrobar AntiCon TBC is suitable for use on a wide variety of interior substrates commonly found in domestic, commercial and industrial buildings. Typical backgrounds include previously painted plaster, cementitious surfaces, brickwork, blockwork, concrete soffits, drylined partitions and sound textured finishes such as Artex or similar decorative plasters. It may also be applied over primed non-ferrous and ferrous metals, subject to correct priming, and over compatible sealers on porous masonry.

In bathrooms, shower rooms, food preparation areas and other spaces subject to high humidity, Hydrobar AntiCon TBC is particularly effective when applied over a suitable acrylic surface sealer that consolidates porous substrates and reduces suction. On highly absorbent or friable backgrounds, a compatible masonry sealer should be used first to avoid excessive soak-in and to help the anti-condensation coating build its required film thickness. The product is intended primarily for internal ceilings and upper wall areas; use on walls subject to frequent impact or aggressive cleaning should be considered carefully, as this is a relatively hard but not heavy-duty scrubbable finish.

 

 

Surface Preparation

Careful surface preparation is essential for long-term performance of any anti-condensation paint. All surfaces must be clean, dry and free from dust, oil, grease, wax, loose or flaking coatings and any other contaminants that could impair adhesion. Remove failing paint or wallpaper back to a firm, sound edge and make good cracks, holes and surface imperfections with a suitable interior filler or decorators’ caulk. Once cured, sand these areas to a smooth, feathered profile and remove all sanding dust.

Glossy or hard oil-based finishes should be lightly abraded with aluminium-oxide paper to provide a key, then washed with a mild detergent solution, rinsed thoroughly with clean water and allowed to dry. Once clean and dull, they should be primed with a good quality high-adhesion acrylic primer in accordance with the manufacturer’s instructions before applying Hydrobar AntiCon TBC.

Bare ferrous metals must be free from rust and millscale, ideally prepared to at least an SA 2.5-equivalent standard. Apply one full coat of a suitable zinc phosphate or similar anti-corrosive metal primer and allow it to dry thoroughly, inspecting for flash rusting; if any corrosion reappears, abrade and spot prime again before overcoating. Non-ferrous metals should be primed with a compatible metal primer as recommended by the primer manufacturer.

Porous masonry and new plaster should be allowed to dry fully and be free from surface laitance. In bathrooms, shower rooms and areas of high humidity, apply one coat of a suitable acrylic surface sealer and allow to dry. In other less critical areas, apply one or two coats of a compatible acrylic masonry sealer, depending on porosity, to bind loose surface particles and balance suction. This sealer approach is also appropriate for unpainted textured finishes such as Artex so that Hydrobar AntiCon TBC can form a continuous thermal film.

Any existing mould growth must be eradicated before painting. Treat affected areas with ACS Mould Wash Concentrate diluted with clean water, following the manufacturer’s dwell time and rinsing instructions. Allow surfaces to dry thoroughly after treatment. Hydrobar AntiCon TBC contains an in-film preservative to help resist future mould colonisation, but it must always be applied to clean, decontaminated surfaces for best results.

 

 

Application Method

ACS Hydrobar AntiCon TBC is supplied ready for use and should not be thinned. Before opening, ensure the container has been stored in a frost-free environment at an appropriate temperature. Gently stir the paint with a clean stirrer to redisperse any settled solids, taking care not to entrain excessive air.

The coating can be applied by brush, medium-nap roller or spray. For brush and roller work, lightly dampen the tool with clean water, remove excess, then load generously and apply a liberal, even coat. Lay off in a consistent direction to achieve a uniform texture and avoid over-spreading, as this reduces the film build that provides the anti-condensation performance. Always work to a wet edge, completing one panel or section at a time to avoid visible lap marks, particularly on ceilings and large uninterrupted walls.

For spray application, consult your spray equipment supplier for tip size and pressure guidance suitable for medium-build waterborne coatings. Maintain a consistent gun distance and overlap passes by around one third to ensure uniform coverage. Mask off adjacent surfaces, fixtures and fittings, and protect floors with suitable sheeting. Regardless of application method, avoid working over areas that have begun to dry, as this can create patchiness and uneven texture.

A minimum of two full coats of Hydrobar AntiCon TBC is required to achieve the correct combined film thickness and thermal performance; three coats are recommended in areas of very high humidity or persistent condensation. Allow the first coat to dry fully before applying subsequent coats.

Coverage

Typical coverage for ACS Hydrobar AntiCon TBC is 4m² - 6m² per litre per coat, depending on surface profile and porosity. Two to three coats are recommended. On smooth, well-sealed surfaces, expect coverage nearer the upper end of the range, while rough or absorbent substrates will tend towards the lower end.

As a practical guide, a 2.5L container will typically cover approximately 5m² - 7.5m² with two coats, or around 3.3m² - 5m² with three coats. A 5L container will usually cover roughly 10–15m² with two coats, or about 6.7m² - 10m² with three coats.

These figures provide an indicative finished area for planning purposes; exact usage will depend on application technique, surface condition and the desired texture. Always ensure sufficient material is available to complete all planned coats on a given area without interruption.

 

 

Drying Time

At around 20°C with good ventilation and moderate humidity, Hydrobar AntiCon TBC is typically touch-dry in about one hour. The coating will usually reach a hard dry condition within 2–3 hours, allowing light handling or masking removal. Recoating can normally take place after 2–3 hours, provided the underlying film is dry and firm to the touch.

Full cure and readiness for return to service, particularly in high humidity environments such as bathrooms or shower rooms, is achieved after approximately 24 hours under standard conditions. Drying and curing times are strongly influenced by temperature, relative humidity and air movement. Cooler conditions, high humidity or poor ventilation will extend these times, so always allow additional drying in marginal conditions before exposing the surface to condensation or regular use.

 

 

Cleaning

Hydrobar AntiCon TBC is a waterborne coating, so tools and equipment should be cleaned as soon as possible after use with clean water. Rinse brushes and rollers thoroughly until the water runs clear and then allow them to dry naturally. Avoid washing large quantities of waste paint into drains; instead, wipe excess material from tools onto absorbent paper and dispose of this in line with local regulations.

Once cured, the coating can be cleaned periodically to maintain appearance. For routine surface cleaning, use warm water with a mild detergent or a diluted specialist mould-wash cleaner recommended for use with anti-mould and anti-condensation coatings. Avoid aggressive chemical cleaners, bleach solutions such as strong sodium hypochlorite, or abrasive pads, as these may damage the film and compromise both the appearance and the in-film biocide protection. Always test any cleaning regime on a small, inconspicuous area first.

 

 

Limitations

ACS Hydrobar AntiCon TBC is designed as an interior anti-condensation and thermal bridge reduction coating. It is not normally recommended for exterior use and should not be used where the surface will be exposed to persistent weathering or direct sunlight. The product must not be applied directly to bare ferrous metal; such surfaces require preparation and priming with a suitable zinc phosphate or comparable anti-corrosive primer prior to sealing and overcoating.

Application conditions are critical. Do not apply the coating if the relative humidity exceeds 85% or if the substrate temperature is less than 3°C above the prevailing dewpoint, as this may result in condensation forming on the wet film, leading to defects. The product should not be thinned, as dilution may reduce its insulating properties and the level of in-film protection. Hydrobar AntiCon TBC is relatively hard once cured but is not intended for substrates subject to heavy wear, frequent scrubbing or mechanical abuse; in such areas, consider complementary protective finishes.

It is important to understand that Hydrobar AntiCon TBC delays the onset of condensation by helping the treated surface remain warmer relative to the surrounding air. If the surface cools to at or below the dewpoint because of severe conditions or inadequate overall heating and ventilation, condensation may still occur. The coating should therefore be viewed as part of a broader strategy that also addresses heating, ventilation and moisture load within the building.

 

 

Other Information

For optimal long-term performance, Hydrobar AntiCon TBC must be stored and used correctly. Store containers in dry, frost-free conditions, ideally between 5°C and 25°C, and keep the lid tightly closed when not in use. Do not allow the product to freeze. If stored for extended periods, stir thoroughly before use to ensure uniform consistency.

Hydrobar AntiCon TBC may be over-painted with ACS Anti Mould & Anti Bacterial Paint Emulsion where enhanced antimicrobial performance is required, creating a combined system that addresses both condensation and mould spore growth. It may also be overcoated with conventional decorative paints, provided a small trial area is tested first for compatibility and adhesion. However, if a conventional topcoat is used, the full moisture-managing and biocidal benefits of Hydrobar AntiCon TBC at the surface may be reduced.

The coating should be fully dry before the area is returned to normal service. In shower rooms and similar spaces, it is good practice to avoid using showers or generating heavy steam for at least 24 hours after final application. Beyond coating works, building owners should implement basic condensation-control measures such as maintaining some background heat, ensuring adequate natural or mechanical ventilation, venting tumble driers externally, using lids on pans during cooking and closing doors to wet rooms while moisture is being generated.

When combined with such good practice, ACS Hydrobar AntiCon TBC provides an effective, durable tool for managing condensation risk on ceilings and walls, helping to protect surfaces from recurrent dampness and the appearance of mould in both residential and commercial properties.

Q) What is ACS Hydrobar AntiCon TBC – Anti Condensation Thermal Paint and what is it designed to do?

A) ACS Hydrobar AntiCon TBC – Anti Condensation Thermal Paint is a single-pack, waterborne coating developed to reduce surface condensation on internal walls and ceilings in homes, commercial buildings and industrial premises. It uses advanced acrylated vinyl acetate resins combined with natural earth minerals and non-toxic pigments to form a fine textured, insulating matt film. This film helps keep surfaces warmer and drier for longer than standard emulsion, delaying the point at which moisture in the air condenses. ACS Hydrobar AntiCon TBC can be used as a thermal primer or as a durable finish coat, helping to manage condensation, discourage mould and protect sensitive areas.

 

Q) How does ACS Hydrobar AntiCon TBC actually reduce condensation on walls and ceilings?

A) ACS Hydrobar AntiCon TBC reduces condensation by improving the thermal behaviour of the painted surface. Standard emulsions sit directly on cold substrates, so when room air reaches dew point, moisture condenses quickly on the paint film. Hydrobar AntiCon TBC incorporates an active mineral system that lowers water uptake and adds genuine insulation, keeping the surface temperature a few degrees higher than untreated backgrounds. This delay gives normal heating and ventilation more time to remove moisture from the air, reducing visible condensation, drips and streaks. The slightly insulating film also helps cold-bridge areas, cutting the sharp temperature differences that typically generate persistent wet patches.

 

Q) Where is ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint most suitable for use?

A) ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is ideal wherever surface condensation has been a persistent problem. Typical domestic areas include bathroom and shower ceilings, kitchen and utility walls, cold external walls in bedrooms and living rooms, and vulnerable corners or window reveals. In commercial and institutional settings it suits corridors, stairwells, welfare areas, plant rooms, changing rooms, clinics, hospital circulation areas, canteens and staff kitchens. In industrial and food-related environments it is often used on ceilings and soffits above production lines or packing areas where warm, humid air condenses on cold surfaces and may drip onto stock, equipment or finishes.

 

Q) Can ACS Hydrobar AntiCon TBC be used as both a thermal primer and a finished topcoat?

A) Yes, ACS Hydrobar AntiCon TBC has been designed to work flexibly either as a dedicated thermal primer or as a fine textured finish in its own right. As a primer, it is applied directly to the prepared substrate to build an insulating, condensation-resistant base layer, which can then be overcoated with a compatible decorative topcoat if a particular colour or sheen is required. As a finish system, two to three coats of ACS Hydrobar AntiCon TBC provide a durable, fine textured matt surface that actively resists condensation without further overcoating. This dual role allows specifiers to balance performance, aesthetics and cleaning requirements on each project.

 

Q) On which substrates is ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint suitable to apply?

A) ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is suitable for most internal mineral and previously painted surfaces that are sound, clean and dry. This includes plaster, plasterboard, cement renders, brickwork, blockwork, concrete soffits, drylined partitions and many textured finishes such as Artex once sealed. It can also be applied over correctly primed ferrous and non-ferrous metals using appropriate metal primers, and over acrylic sealers on porous masonry. In high humidity locations, sealing very absorbent surfaces beforehand improves film build and performance. It is intended primarily for ceilings and wall areas susceptible to condensation, rather than for floors or heavy-duty impact zones.

 

Q) How should surfaces be prepared before applying ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint?

A) Preparation for ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint follows good trade practice but needs extra care in problem areas. Remove all loose or flaking paint, failing coatings and wallpaper, then fill cracks and defects with a compatible filler and sand smooth. Wash down greasy or contaminated surfaces with a mild detergent, rinse and allow to dry. Glossy or oil-based coatings should be abraded to give a key and primed with a high-adhesion acrylic primer. Porous masonry and new plaster benefit from an acrylic surface sealer or masonry sealer to control suction. Any existing mould must be treated with ACS Mould Wash Concentrate and fully removed before painting.

 

Q) What is the correct application method for ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint?

A) ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is supplied ready to use and should be stirred thoroughly before application without thinning. It can be applied by brush, medium-nap roller or spray. When brushing or rolling, load the tool generously and apply a liberal, even coat, laying off in one direction to achieve a uniform fine texture and avoiding over-spreading, as film thickness is critical for thermal performance. Always maintain a wet edge and complete each wall or ceiling section in one pass to prevent lap marks. For spray use, select equipment suitable for medium-build waterborne coatings and apply cross passes for even coverage, masking adjacent surfaces carefully.

 

Q) How much coverage can I expect from ACS Hydrobar AntiCon TBC and how many coats are needed?

A) ACS Hydrobar AntiCon TBC typically covers around 4–6m² per litre per coat, depending on surface texture and porosity. Because the anti condensation effect depends on a sufficient insulating film thickness, a minimum of two full coats is required, and three coats are recommended in very high humidity or severe condensation areas. As a practical guide, a 2.5 litre tin will generally provide two coats over about 5–7.5m², while a 5 litre tin will cover roughly 10–15m² with two coats. Rough or highly absorbent backgrounds may reduce these figures. It is important to ensure enough material is available to complete all planned coats on each area.

 

Q) What are the drying and curing times for ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint?

A) In typical indoor conditions of around 20°C with reasonable ventilation, ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is usually touch dry in about one hour and hard dry within two to three hours. Recoating is normally possible after two to three hours, provided the first coat is dry and firm. Full cure, when the coating achieves its designed mechanical strength and condensation resistance, is reached after roughly 24 hours. Cooler temperatures, high humidity or poor air movement extend these times, so bathrooms, shower rooms and plant areas may need longer before being returned to heavy use. Avoid exposing freshly painted surfaces to heavy condensation during early curing.

 

Q) Can ACS Hydrobar AntiCon TBC be overcoated with other paints such as standard emulsions or anti mould products?

A) ACS Hydrobar AntiCon TBC can be overcoated with compatible waterborne decorative paints once fully dry, although doing so will interpose another film between the room environment and the thermal coating. In many cases it is best left exposed as the finish. Where enhanced mould control is required, ACS Hydrobar AntiCon TBC may be overpainted with ACS Anti Mould & Anti Bacterial Paint Emulsion, creating a combined system that tackles both condensation and surface microbiological growth. If standard emulsions are used, a test area should always be carried out first to confirm adhesion and appearance, and to ensure the decorative coat does not compromise the underlying performance.

 

Q) What are the main advantages of ACS Hydrobar AntiCon TBC over normal emulsion paint?

A) ACS Hydrobar AntiCon TBC offers several advantages over normal emulsion paints in condensation-prone environments. Its mineral-loaded formulation provides genuine thermal resistance at the surface, helping to keep walls and ceilings warmer and reducing condensation and drips. The active mineral system also limits water uptake into the film, so damp patches dry more quickly. The coating’s fine textured matt finish disguises minor defects better than many smooth emulsions, while the tough, slightly elastic film resists microcracking under normal movement. In addition, ACS Hydrobar AntiCon TBC contains an in-film preservative to help protect against fungal attack, making it more robust in humid areas than standard decorative coatings.

 

Q) Are there any limitations or situations where ACS Hydrobar AntiCon TBC should not be used?

A) ACS Hydrobar AntiCon TBC is designed for interior use and is not generally suitable for exterior façades or areas subject to continuous direct weathering or strong UV exposure. It should not be applied directly to bare ferrous metal without prior priming, nor to floors or surfaces exposed to heavy mechanical wear or frequent harsh scrubbing. Application should be avoided where relative humidity exceeds about 85% or where the substrate temperature is close to dew point, as condensation on the wet film can cause defects. The product must not be thinned, and it should not be used as a substitute for correcting structural damp, leaks or serious moisture ingress.

 

Q) Is ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint safe to use in occupied homes and sensitive environments?

A) ACS Hydrobar AntiCon TBC Anti Condensation Thermal Paint is waterborne, low odour and based on acrylated vinyl acetate resins with non-toxic pigments and natural earth minerals, making it suitable for use in occupied homes, offices, schools and many sensitive environments. As with any professional coating, standard precautions apply: ensure good ventilation during application and drying, avoid skin and eye contact, and wear suitable gloves, eye protection and work clothing. Once fully dry, the coating forms an inert, stable film. The in-can biocide is present to protect the wet product and dried film from fungal attack and is used within regulatory limits, provided the product is used strictly as directed.

 

Q) How should ACS Hydrobar AntiCon TBC coated surfaces be cleaned and maintained?

A) Once ACS Hydrobar AntiCon TBC has fully cured, surfaces can be cleaned periodically to maintain appearance and hygiene. For routine cleaning, use warm water with a mild detergent and a soft cloth or sponge, working gently to avoid damaging the fine textured surface. Avoid aggressive chemical cleaners, strong bleach solutions and abrasive pads, as these can erode or burnish the film and potentially reduce its functional performance. Always test any new cleaning method on a small, inconspicuous area first. Good housekeeping, including prompt wiping of occasional splashes and controlling excess moisture, will help the anti condensation coating perform at its best over the long term.

 

Q) How does ACS Hydrobar AntiCon TBC fit into a wider strategy for controlling condensation and mould?

A) ACS Hydrobar AntiCon TBC should be viewed as a key part of a broader condensation and mould control strategy rather than a complete solution on its own. By raising surface temperatures and reducing water uptake, it significantly lowers the likelihood and severity of condensation on problem ceilings and walls. However, building owners and occupants should still address underlying issues such as inadequate ventilation, intermittent or insufficient heating, high internal moisture loads and structural defects. Using ACS Hydrobar AntiCon TBC alongside sensible measures like extractor fans, trickle vents, background heating and prompt repair of leaks provides a more reliable, long-term defence against condensation damage and mould formation.
