Ultracure Damp Proof Cream - 380ml Cartridge Kits

Health & Safety Recommendations

Ultracure Damp Proof Cream – 380ml Cartridge Kits must be used with appropriate personal protective equipment. Always wear the supplied green nitrile gauntlets, suitable eye protection and, where drilling produces dust, a suitable dust mask. Ensure good ventilation in all work areas, particularly in confined spaces, basements and cellars. Avoid skin and eye contact with the cream and avoid breathing dust when drilling into masonry.

Before starting work, read the product label and safety data sheet in full. Keep the cartridges, drill bits and applicator gun away from children and pets. Do not eat, drink or smoke while handling the product. In case of accidental contact with skin, wash immediately with soap and water. If the cream contacts eyes, rinse with plenty of clean water and seek medical advice if irritation persists. If ingested, rinse the mouth with water, do not induce vomiting and obtain medical advice promptly.

Substrate Suitability

Ultracure Damp Proof Cream is suitable for most common masonry types, including solid brick, cavity brick, blockwork and many stone walls, where a rising damp problem has been correctly diagnosed. It is designed specifically for injection into a selected horizontal mortar bed to form a chemical damp proof course and can be used in both internal and external walls, provided the wall is structurally sound.

Walls with severe salt contamination, friable or crumbling mortar, or extensive structural defects should be assessed and repaired as necessary before treatment. In all cases, the cream should be used as part of a complete rising damp treatment specification, including salt resistant replastering such as Wykamol Renovation Plaster or Wykamol Renderproof to isolate hygroscopic salts from the new decorative surface. Where walls incorporate random stone or rubble infill, drilling patterns may need to be adapted to ensure full coverage of the mortar bed and perpends.

Drilling Preparation

Begin by addressing obvious sources of moisture. Check and service rainwater goods, ensuring gutters, downpipes and gullies are sound, clean and free flowing. Repair or provide suitable drainage to carry surface water away from the building. Where internal floor levels are below external ground levels, it may be necessary to form external trenches or lower ground where practicable; if this cannot be done, the new DPC will usually be installed at least 150mm above external ground level and the wall tanked or membrane-lined below that point to prevent lateral moisture migration.

Internally, remove skirting boards, fixtures, and any render or plaster necessary to expose the chosen mortar course for drilling. Salt contaminated plaster should be removed to at least 300mm above the highest visible signs of rising damp. Inspect timber joists and plates bearing into the wall for signs of fungal decay and specify repair or replacement where needed. Check wall cavities and clear debris, particularly at the level where the new DPC will be installed, to prevent bridging across the new damp proof course.

DPC height should, wherever possible, be at least 150mm above external ground level and as close to internal finished floor level as practicable for solid floors. For cavity walls, either treat each leaf separately or adopt a through–drill method while ensuring the cavity is clean and that both leaves are fully injected. In thicker random stone or rubble walls above about 350mm, drilling from both sides at corresponding heights is often required to ensure complete coverage.

Application Method

Using the supplied 12mm x 260mm SDS drill bit, drill a series of horizontal holes into the selected mortar bed at centres not exceeding 120mm. Hole depth should be approximately 90% of the wall thickness, with typical drill depths shown in the drilling table on the product page. Aim to follow a continuous mortar course and ensure holes intersect the base of vertical perpends so that the entire bed is treated. Remove drilling dust from each hole with a blow pump or vacuum to improve contact between the cream and the mortar.

Insert a 380ml Ultracure cartridge into the C4 Economy Skeleton Gun and fit the extension nozzle firmly. Starting with the nozzle fully inserted at the back of the hole, slowly squeeze the trigger and withdraw the nozzle as the hole fills, ensuring the bore is filled uniformly to about 10mm from the surface. Maintain a steady pace to avoid air gaps. Repeat for each hole along the treatment line, checking that all holes are fully backfilled. On cavity walls treated from one side, ensure that the drill pattern and injection fully treat both leaves as per your chosen method, and that cavities are clean beforehand.

During application, wear the supplied nitrile gauntlets and keep a cloth to wipe any small excess from the masonry face. Avoid injecting into loose or crumbling mortar; if holes collapse or block, re-drill adjacent holes at the same level to ensure sufficient volume of Ultracure is delivered. Once the full run has been treated, visually confirm that all injection points are filled to the correct level and rectify any short-filled holes immediately.

Coverage

Coverage for Ultracure depends on wall thickness, construction type and the number of holes drilled at 120mm centres. A single 380ml cartridge will typically treat a limited run of wall at standard thickness, and longer walls will require multiple cartridges.

To plan the number of cartridges required for your project, refer to the Ultracure coverage table below, which sets out approximate treated lengths per 380ml cartridge for common wall thicknesses in both single leaf and cavity constructions. Always add a margin for wastage and for variations in wall construction.

Curing Time

Once injected, Ultracure Damp Proof Cream begins to migrate into the surrounding mortar and masonry immediately. The cream gradually reverts to a liquid phase, diffuses into the pore structure and then chemically reacts to form a continuous hydrophobic damp proof course. In typical conditions, the barrier is effectively established within several days, but full drying of the wall fabric takes longer.

Final cure and full performance against rising damp can take between 2 and 6 weeks depending on wall thickness, initial moisture content, temperature and ventilation. Heavily saturated or thick masonry may take longer to dry, and visible damp staining can persist until salts have been managed through appropriate replastering. It is advisable to allow at least 14 days after injection before undertaking replastering or other finishing work, wherever programme allows.

Finishing

Externally, drilled injection holes can be made good once the cream has been installed. Many installers choose to plug the holes with Universal DPC Injection Plugs, which are available in different colours to blend with common brickwork and provide a neat, consistent finish along the treatment line. Alternatively, holes may be pointed up with a compatible sand and cement mortar matched to the existing joint profile and colour.

Internally, injection holes are usually left open, with the new salt-resistant plaster or renovation system finished slightly above the level of the DPC so that the treatment line remains visible for future inspection. Ensure any making good respects the damp proof course position and does not bridge the newly formed barrier.

Decoration

After Ultracure treatment, all salt-contaminated plaster and finishes in the damp zone should be stripped and replaced using an appropriate Wykamol replastering system such as Wykamol Renovation Plaster or Wykamol Renderproof. These are formulated to resist hygroscopic salts left behind by rising damp and to prevent future staining through otherwise sound new finishes.

Once the new plaster has fully cured and the wall has had adequate time to dry down, it can be decorated with breathable paints or other compatible finishes. Avoid impervious wall coverings or vinyl wallpapers that could trap residual moisture. Always follow the plaster manufacturer’s guidance on drying times and decoration, and delay redecoration if there is any visible dampness remaining.

Cleaning

Any Ultracure cream spilled during application should be wiped up immediately with a damp cloth before it begins to cure. Contaminated surfaces that are not part of the treatment area should be washed with warm soapy water as soon as possible. Once fully cured within the wall, Ultracure is not intended to be removed; if small cured residues remain on exposed surfaces, they may require gentle mechanical removal, taking care not to damage the substrate.

After use, release the pressure on the C4 Economy Skeleton Gun, remove the partially used cartridge if necessary and cap it securely following the manufacturer’s instructions so it can be reused within its shelf life. Clean the exterior of the gun and any reusable extension nozzles to prevent build-up of cured material that could restrict future flow.

Limitations

Ultracure Damp Proof Cream – 380ml Cartridge Kits are designed specifically for treating rising damp by forming a new damp proof course. They are not a general solution for penetrating damp, plumbing leaks, condensation or structural waterproofing failures, which must be diagnosed and remedied separately. The system relies on correct diagnosis of rising damp, appropriate drilling, complete injection and proper management of salt-contaminated plaster.

Walls with exceptionally high moisture levels, highly irregular construction, rubble-filled cores or severe structural defects may require additional measures or alternative approaches. Always ensure wall cavities are free of debris to avoid bridging. The cream should not be injected into frozen masonry or where temperatures are too low for curing. As with any chemical DPC, results will be compromised if bridging occurs from internal screeds, external renders, raised ground levels or debris-filled cavities that bypass the new barrier.

Other Information

Ultracure Damp Proof Cream is supported by BBA Certification (Certificate No. 02/3961), confirming that, when installed in accordance with the manufacturer’s instructions and relevant British Standards such as BS6576:2005, it provides durable protection against rising damp for at least 20 years. The 380ml cartridge kit format brings this performance into a compact, convenient package suitable for both professional damp-proofing contractors and competent DIY users working to a recognised specification.

Store cartridges, drill bits and accessories in a cool, dry place, upright where possible, and protect from extreme temperatures and direct sunlight. Always follow Wykamol’s latest technical guidance for diagnosis of damp, installation of chemical DPCs and replastering specifications, and consult a qualified surveyor if the cause of damp is uncertain or if structural issues are suspected.

Q) What is Ultracure Damp Proof Cream – 380ml Cartridge Kits and what are they designed to do?

A) Ultracure Damp Proof Cream – 380ml Cartridge Kits are complete rising damp treatment packages built around Wykamol’s BBA-certified Ultracure Damp Proof Cream. Each kit is designed to let you install a new chemical damp proof course using standard tools rather than high-pressure injection equipment. The silane-based cream is injected into a line of 12mm holes drilled along a selected mortar bed at DPC level. Once in the wall, the Ultracure cream diffuses into the mortar and adjacent masonry and cures to form a continuous hydrophobic barrier that blocks rising damp while still allowing the wall to breathe. The kits are suitable for treating rising damp in brick, block and many stone walls in domestic, commercial and even historic buildings, provided the walls are structurally sound and replastering is carried out with a suitable salt-resistant system. With correct installation they provide an in-situ damp proof course that is effective for at least 20 years, offering a clean, low-disruption alternative to physically cutting in a new DPC.

Q) How does the Ultracure Damp Proof Cream from the 380ml Cartridge Kits stop rising damp inside the wall?

A) The Ultracure Damp Proof Cream in the 380ml Cartridge Kits uses proven silane chemistry to control rising damp. After drilling 12mm diameter holes along the chosen mortar joint, the cream is injected with the supplied skeleton gun and extension nozzle. Because the product is thixotropic, it remains in the bore of the hole instead of running out, then gradually reverts to a liquid phase and diffuses sideways and vertically into the fine capillaries of the mortar and brick or stone. As it reacts with the mineral substrate, the silane forms a long-lasting hydrophobic zone that lines the pores and capillaries. This zone repels liquid water rising from the ground via capillary action but still allows water vapour to move, so the wall can dry down naturally. Over time, the moisture above the new chemical DPC reduces, and, with appropriate replastering to deal with salts, internal finishes can remain sound and dry.

Q) What is included in an Ultracure Damp Proof Cream – 380ml Cartridge Kit and why is that useful?

A) Each Ultracure Damp Proof Cream – 380ml Cartridge Kit is supplied as a ready-to-use package that brings together the key components needed for installation. You receive several 380ml Ultracure cartridges appropriate to the kit size, a C4 Economy Skeleton Gun sized for these cartridges, a pair of green nitrile gauntlets for safe handling, and one or more 12mm x 260mm SDS drill bits matched to the recommended hole diameter and depth. The cartridges provide the silane cream that forms the chemical DPC, the skeleton gun ensures controlled, low-pressure injection, and the extension nozzle fits into the drilled holes to reach the back of the wall. The SDS drill bit is long enough for typical UK wall thicknesses and ensures you achieve the correct 12mm bore. This all-in-one approach saves time sourcing compatible tools, reduces the risk of using the wrong drill size or gun, and makes the kits particularly convenient for smaller contractors and competent DIY users who want a well thought-out damp proofing solution.

Q) In what types of properties and situations should Ultracure Damp Proof Cream – 380ml Cartridge Kits be used?

A) Ultracure Damp Proof Cream – 380ml Cartridge Kits are designed for situations where rising damp has been correctly diagnosed and a new damp proof course is required without major structural disturbance. Typical properties include older houses without an effective original DPC, traditional solid-wall buildings, cavity brick homes where the physical DPC has failed or been bridged, and ground floor rooms showing tide marks, powdery plaster and salt deposits. The kits are also suitable for individual damp-affected walls in commercial premises, small offices, schools and public buildings where localised rising damp is causing damage. Because the system is quiet, low odour and requires only a drill and the supplied injection gun, it is particularly suited to occupied dwellings where disruption must be kept to a minimum. Ultracure Damp Proof Cream – 380ml Cartridge Kits are not a solution for condensation or penetrating damp, but they are highly effective when used specifically for rising damp in sound masonry.

Q) What masonry and wall constructions can be treated with Ultracure Damp Proof Cream – 380ml Cartridge Kits?

A) Ultracure Damp Proof Cream – 380ml Cartridge Kits are suitable for most standard masonry constructions found in UK buildings. They can be used in solid brick walls, cavity brick walls, blockwork and many traditional stone walls. In solid walls, a continuous row of 12mm holes is drilled along a selected mortar bed, usually just above internal floor level and at least 150mm above external ground level where possible. In cavity walls, each leaf must be treated either by drilling and injecting both leaves separately or by using a through-drilling method while ensuring that the cavity is clear of debris. Random stone and rubble-infill walls can also be treated, but drilling patterns may need to be adapted so that the chosen course and perpends are thoroughly injected; drilling from both sides is often necessary on thicker walls. As with any chemical DPC, the substrate must be reasonably sound, and severely crumbling mortar or very unusual constructions should be assessed by a damp specialist before relying solely on Ultracure.

Q) How should I prepare the wall and choose the correct DPC height before using the Ultracure 380ml Cartridge Kits?

A) Proper preparation is critical before using Ultracure Damp Proof Cream – 380ml Cartridge Kits. First, address obvious external defects: repair leaking gutters and downpipes, clear blocked gullies and ensure external ground and paving fall away from the building. Next, decide on the height of the new chemical DPC. Ideally this will be at the same level as the original DPC if present, or at least 150mm above external ground level where there is no physical DPC. Internally, remove skirting boards and sufficient plaster to expose the chosen mortar bed; salt-contaminated plaster is normally removed to at least 300mm above the highest visible signs of rising damp. Inspect timber joists and wall plates bearing into the wall for signs of decay and arrange appropriate repairs. In cavity walls, clear debris at DPC level to avoid bridging. Only once the wall has been prepared and the mortar joint fully exposed should you mark out the drill line at the selected DPC height and proceed with drilling.

Q) What drilling pattern and hole depth should I use with Ultracure Damp Proof Cream – 380ml Cartridge Kits?

A) When using Ultracure Damp Proof Cream – 380ml Cartridge Kits, you should follow the standard Ultracure drilling pattern. Use the supplied 12mm x 260mm SDS drill bit to form horizontal holes along the selected mortar bed at centres not exceeding 120mm. Holes should be drilled to a depth of roughly 90% of the wall thickness, so around 100mm for a 115mm wall, approximately 210mm for a 230mm wall, about 320mm for a 345mm wall and around 430mm for a 460mm wall. For intermediate wall thicknesses, depth is calculated on a pro-rata basis. In thicker walls above about 350mm, drilling from both sides at matching heights is often recommended to ensure full penetration of the silane cream through the section. During drilling, keep the bit level so that holes follow the same course, and remove all dust from each hole using a blow pump or vacuum. Clean holes help the Ultracure cream make good contact with the mortar and maximise diffusion.

Q) How do I inject Ultracure Damp Proof Cream using the C4 Economy Skeleton Gun supplied in the kit?

A) To inject Ultracure Damp Proof Cream with the C4 Economy Skeleton Gun supplied in the 380ml Cartridge Kits, first load a 380ml cartridge into the gun and fit the extension nozzle firmly. Cut the nozzle tip to suit the 12mm drill hole and ensure it can reach near the back of the hole. Insert the nozzle fully to the rear of the drilled hole and begin squeezing the gun trigger to extrude the cream. As the hole fills, steadily withdraw the nozzle while maintaining consistent pressure on the trigger so that the bore is filled evenly from back to front. Aim to fill each hole to within about 10mm of the surface; this gives room for minor expansion and eliminates surface spillage. Move methodically along the treatment line, ensuring that no holes are missed and that each is properly backfilled. If a hole appears to take unusually little product, check for blockages or collapsed mortar and, if necessary, re-drill nearby to achieve the required volume of Ultracure cream.

Q) How many metres of wall can one Ultracure Damp Proof Cream – 380ml Cartridge treat and how do I estimate coverage?

A) The coverage of a single 380ml Ultracure Damp Proof Cream cartridge depends on wall thickness and the number of 12mm diameter holes drilled at 120mm centres. Thicker walls require deeper holes, which obviously consume more cream per metre. As a simple way to estimate, calculate how many holes will be drilled over the total wall length (length in millimetres divided by 120mm, rounded up), then multiply by the approximate hole volume based on the 12mm diameter and 90% wall thickness. This total volume, converted to millilitres, tells you how many 380ml cartridges are required for that run of wall. In practice, installers often refer to Wykamol’s coverage tables, which give indicative treated lengths per cartridge for common wall thicknesses. Whatever method you use, it is wise to add a margin for wastage, re-drilling and small variations in wall depth, especially on older properties where masonry is less regular than modern blockwork.

Q) How long does Ultracure Damp Proof Cream from the 380ml Cartridge Kits take to work and when will my walls start to feel dry?

A) After injection with the Ultracure Damp Proof Cream – 380ml Cartridge Kits, the silane cream begins diffusing into the mortar and masonry almost immediately. The chemical damp proof course itself is usually formed within a period of roughly 2–6 weeks, depending on the wall’s thickness, porosity, moisture content and the ambient temperature and ventilation. However, the wall above the new DPC will not dry out overnight. Existing moisture and salts held in the masonry and plaster must migrate and evaporate over time. In a typical solid brick wall with moderate dampness, noticeable improvements can be seen within a few months, but complete drying may take six to twelve months, especially where walls were heavily saturated. Good background heating, regular ventilation and appropriate salt-resistant replastering are essential to support the drying process. During this period, avoid applying impervious finishes that could trap moisture behind the surface.

Q) Why is salt-resistant replastering important after using Ultracure Damp Proof Cream – 380ml Cartridge Kits?

A) Installing Ultracure Damp Proof Cream with the 380ml Cartridge Kits stops additional ground moisture from rising, but it does not remove the hygroscopic salts that have accumulated in the masonry and plaster during years of dampness. These salts, such as nitrates and chlorides, can continue to absorb moisture from the air and cause local damp patches or surface staining even when the wall itself is drying out. For this reason, it is standard practice to remove salt-contaminated plaster to at least 300mm above the highest visible damp mark and then reinstate with a specifically designed salt-resistant plaster system such as Wykamol Renovation Plaster or Renderproof. These systems isolate residual salts from the finished surface and allow moisture to disperse safely, preventing recurrence of staining and blistering. Without salt-resistant replastering, the effectiveness of Ultracure Damp Proof Cream in restoring a reliable decorative finish will be seriously compromised.

Q) Can Ultracure Damp Proof Cream – 380ml Cartridge Kits be used in basements and below-ground walls?

A) Ultracure Damp Proof Cream – 380ml Cartridge Kits can certainly be used to control rising damp in basement and lower ground level walls, but they should not be seen as a complete below-ground waterproofing system. In basements, moisture often enters laterally through retaining walls as well as via capillary rise from below. The Ultracure chemical DPC will address the vertical moisture pathway caused by rising damp, but any lateral ingress due to hydrostatic pressure requires additional measures, such as cementitious tanking or cavity drainage membranes designed to BS 8102 standards. In many refurbishment projects, the best approach is to combine Ultracure injection at or near floor level with an internal membrane system and appropriate drainage and ventilation. Before using the 380ml Cartridge Kits in a basement, it is advisable to obtain a professional damp and waterproofing survey so that rising damp is properly separated from other forms of moisture and the Ultracure system is integrated into a wider, robust design.

Q) Are Ultracure Damp Proof Cream – 380ml Cartridge Kits suitable for DIY users, or should installation be left to professionals?

A) Ultracure Damp Proof Cream – 380ml Cartridge Kits are intentionally designed to be accessible for both professional contractors and competent DIY users. Because they rely on a simple drilling pattern, standard SDS drill, and a manual C4 skeleton gun, there is no need for high-pressure pumps or specialist machinery. A careful homeowner or facilities manager who is comfortable with drilling masonry and following technical instructions can often install Ultracure successfully on straightforward wall runs. However, the key challenge is not the physical injection but the correct diagnosis of rising damp, the identification of all affected areas, and the integration of salt-resistant replastering. For complex buildings, mixed wall constructions, basements or where the source of damp is uncertain, engaging a qualified damp surveyor or specialist contractor is strongly recommended. Even where DIY installation of Ultracure is chosen, many users still prefer professional help with replastering and final diagnostics to ensure a lasting outcome.

Q) What health and safety precautions should I follow when using Ultracure Damp Proof Cream – 380ml Cartridge Kits?

A) When using Ultracure Damp Proof Cream – 380ml Cartridge Kits, you should follow standard damp-proofing safety practice. Wear the supplied green nitrile gauntlets to protect your hands from spills and irritants. Always use eye protection when drilling and injecting, as brick dust and small splashes can cause irritation. A suitable dust mask is strongly recommended while drilling 12mm holes, especially in older masonry where dust levels may be high. Ensure that the work area is well ventilated, particularly in confined spaces such as cellars or small rooms. Avoid eating, drinking or smoking during application, and wash hands thoroughly after handling cartridges or tools. If Ultracure cream contacts skin, wash it off promptly with soap and water; if it reaches the eyes, irrigate immediately with clean water and seek medical advice if discomfort continues. Keep all kit components out of the reach of children and dispose of waste materials responsibly in accordance with local regulations.

Q) Can the Ultracure 380ml cartridges be resealed and reused, and how should I look after the gun and drill bits?

A) Ultracure Damp Proof Cream – 380ml cartridges can usually be resealed and reused provided the nozzle is capped carefully and the cartridge is stored correctly between jobs. After finishing a run, release the pressure on the C4 Economy Skeleton Gun and remove the cartridge if it will not be used for some time. Wipe any cream from the nozzle and either fit the original cap or seal it with a tight-fitting plug to minimise air contact, then store it upright in a cool, dry place. For the skeleton gun, clean off external residues and ensure the plunger moves freely; there is no need for solvent flushing, as the cream does not cure inside the closed cartridge body. The supplied 12mm x 260mm SDS drill bit should be brushed clean after use, checked for wear and stored dry to prevent corrosion. If a nozzle or bit becomes badly clogged or worn, it should be replaced, as accurate drilling and smooth extrusion are key to consistent Ultracure dosing.

Q) What are the main advantages of Ultracure Damp Proof Cream – 380ml Cartridge Kits over traditional liquid injection pumps?

A) Ultracure Damp Proof Cream – 380ml Cartridge Kits offer several clear advantages over older liquid injection systems that rely on high-pressure pumps. Because Ultracure is supplied as a thixotropic cream, it stays in the 12mm hole instead of running down voids or into cavities, which reduces mess and ensures the active silane is concentrated where it is needed. Cartridge application with the C4 skeleton gun is low pressure and highly controllable, which minimises leakage and allows precise dosing at each injection point. There is no requirement for pump hire, assembly, priming, flushing or pump cleaning between jobs, which saves time and reduces the risk of contamination. The kits are compact and easy to transport, making them ideal for small remedial projects, isolated walls and work in occupied dwellings. The virtually odourless, low-hazard nature of Ultracure cream also offers a more pleasant working environment compared with some solvent-heavy liquid systems.

Q) What limitations should I be aware of when using Ultracure Damp Proof Cream – 380ml Cartridge Kits?

A) While Ultracure Damp Proof Cream – 380ml Cartridge Kits are highly effective for treating rising damp, they do have limitations. They are not designed to deal with penetrating damp, defective roofing, plumbing leaks or condensation, which all require separate investigation and remedial measures. Their performance depends on correct drilling at the specified spacing and depth; if holes are too shallow, too widely spaced or omitted in areas of changing levels, the chemical DPC may have gaps. In walls with rubble cores, heavily voided cavities or severe structural defects, diffusion of the cream may be uneven and a combined approach using membranes and other systems may be necessary. Ultracure must not be injected into frozen masonry or extremely saturated conditions where curing could be delayed. Finally, the system will not prevent damp bridging caused by internal screeds, external renders, debris-filled cavities or raised ground levels that bypass the newly formed DPC, so these issues must be resolved as part of a comprehensive damp management plan.

Q) How do Ultracure Damp Proof Cream – 380ml Cartridge Kits work with Wykamol membranes and other damp proofing products?

A) Ultracure Damp Proof Cream – 380ml Cartridge Kits are designed to integrate smoothly with other Wykamol damp proofing and waterproofing products. In many projects, the Ultracure cream is installed first to deal with rising damp, forming a new chemical DPC at or near floor level. Above this line, salt-contaminated plaster is removed and replaced with Wykamol Renovation Plaster or Renderproof to manage salts, or with a studded damp-proof mesh membrane where a physical barrier and dry lining surface are required. The mesh membranes can be fixed over the treated wall to create a ventilated or drained cavity, with plasterboard or plaster applied over the mesh to create a new decorative surface. In basements, Ultracure injection may be combined with cavity drain membranes and sump systems as part of a BS 8102 compliant waterproofing design. By using Ultracure alongside compatible Wykamol systems, you can create a layered defence against both rising damp and lateral moisture, tailored to the complexity of the building.

Q) How long will the chemical DPC created with Ultracure Damp Proof Cream – 380ml Cartridge Kits last and is it certified?

A) The chemical damp proof course formed by Ultracure Damp Proof Cream – 380ml Cartridge Kits is designed to provide long-term protection against rising damp. The silane-based hydrophobic zone created within the mortar and masonry is expected to remain effective for at least 20 years under normal conditions when installed in accordance with the manufacturer’s instructions and relevant British Standards. This performance is supported by BBA Certification (Certificate No. 02/3961), which provides independent verification of the product’s effectiveness, durability and suitability for use as a remedial DPC system. For landlords, surveyors and property owners, this certification and stated service life give reassurance that Ultracure is an appropriate long-term remediation measure. As with any damp proofing work, continued effectiveness also relies on good building maintenance, including control of external ground levels, sound rainwater goods and adequate ventilation.

Q) How should Ultracure Damp Proof Cream – 380ml Cartridge Kits be stored and handled between jobs?

A) Ultracure Damp Proof Cream – 380ml Cartridge Kits should be stored and handled with the same care as other professional damp proofing products. Keep cartridges, the C4 Economy Skeleton Gun, nitrile gauntlets and drill bits in a cool, dry place, protected from frost and direct sunlight. Ideally, store cartridges upright at moderate temperatures within the range specified on the packaging to preserve their shelf life and maintain consistent extrusion characteristics. Avoid leaving kits in very hot vehicles or damp conditions for long periods. Between jobs, ensure cartridge nozzles are sealed securely, the gun is clean and functional, and the SDS drill bit is free from rust and debris. When transporting Ultracure Damp Proof Cream – 380ml Cartridge Kits to site, secure them so that cartridges and tools are not damaged in transit. Following these simple storage and handling steps helps ensure that the cream remains in good condition and ready to provide reliable rising damp treatment whenever it is needed.
