Ultracure Damp Proof Cream - 1 Litre Cartridge Kits

Health & Safety Recommendations

Read the product label and Safety Data Sheet before use and follow all local site safety rules. Wear suitable gloves, eye protection and workwear, and avoid prolonged skin contact. Use suitable dust extraction or respiratory protection when drilling, as mortar and masonry dust can be harmful. Ensure safe access along the full length of the wall and keep the work area clear of trip hazards, trailing cables and debris. If working externally, check for services and maintain safe working distances from openings, neighbouring boundaries and public areas.

Ultracure is designed to be installed into masonry at low pressure using a cartridge gun. Do not inject into live electrical areas or unknown voids. If the wall is structurally unsound, heavily cracked, or at risk of collapse, rectify this before treatment. Where there is any doubt about structural stability, service routes, or the cause of dampness, seek competent professional advice before starting.

Substrate Suitability

Ultracure Damp Proof Cream is intended for injection into masonry to control rising damp, typically via a mortar bed. It is suitable for most common masonry types, including brickwork, blockwork and many stone constructions, provided a practical drilling pattern can be formed to create continuity across the chosen course.

Cavity walls can be treated either by treating each leaf as a separate wall or by drilling in a way that allows a continuous injection process across the cavity into the outer leaf, but only if the cavity is clear and the drilling plan is appropriate. Random stone and rubble-filled walls require particular care, as the mortar line can be irregular and some stones may be porous. In walls thicker than 350mm, drilling from both sides at a corresponding height is typically required to achieve coverage through the full thickness.

Drilling Preparation

Start by confirming that rising damp is the problem being addressed and remove or reduce any external sources of water that can mimic rising damp. Check and repair rainwater goods, gutters, downpipes and drains, and ensure surface water is directed away from the building. Confirm that external ground levels are not bridging the damp proof course. As a general rule the DPC line should be at least 150mm above external ground level wherever possible.

Internally, remove skirtings, fixings and finishes that obstruct access to the chosen mortar bed. Salt-contaminated plaster should be removed from the area to be treated to at least 300mm above the highest visible level of damp staining, or higher if contamination is extensive. If internal floors are below external ground level, you may need to lower external ground locally, or install the DPC higher and tank the internal wall below the DPC to prevent lateral moisture and salt migration.

Check timbers at low level for signs of fungal decay and address any timber defects as part of the overall remediation. For cavity walls, ensure the cavity is clear of debris at the intended DPC level, as bridging within the cavity can compromise performance. Where ground levels change or where walls adjoin untreated structures, plan vertical DPC continuity to isolate and connect treated areas as required.

Drill Hole Size, Depth And Spacing

Drill 12mm diameter holes horizontally in the selected mortar bed. Keep hole centres no greater than 120mm apart. The target hole depth is typically around 90% of the wall thickness, adjusted pro rata for intermediate thicknesses.

As a practical guide for common wall thicknesses, drill to approximately 100mm for 115mm walls, 210mm for 230mm walls, 320mm for 345mm walls, and 430mm for 460mm walls. In irregular masonry, ensure the drilling pattern targets the base of all perpends along the chosen course so that continuity is maintained across the wall.

Where drilling holes become blocked, re-drill immediately prior to injection or drill an additional hole nearby to ensure the correct volume of cream is introduced. Keep the drill line consistent and level, and aim to maintain the correct DPC height relative to external ground and internal floor levels.

Application Method

Load the Ultracure 1L cartridge into the Cox Powerflow Cartridge Gun, pierce the thin metal film at the top of the 1 Litre Cartridge and fit the brass DPC nozzle securely, ensuring the cartridge is seated correctly and the drive mechanism engages smoothly.

Insert the brass nozzle to the full depth of the drilled hole. Begin dispensing and steadily backfill as you withdraw the nozzle, aiming to fill the hole fully to within approximately 10mm of the face. This method helps prevent voids and ensures the cream is placed from the rear of the hole outwards for consistent distribution.

Continue hole by hole along the selected mortar bed, maintaining the same fill level. On cavity walls, ensure that holes in each leaf are filled fully where each leaf is being treated separately. Keep the nozzle clean and work methodically to avoid missing holes, particularly around corners, reveals, chimney breasts and changes in wall thickness where continuity is most at risk.

Wipe up spills immediately and dispose of contaminated wipes appropriately. If Ultracure contacts non-target surfaces such as paving or masonry faces, it will often dry clear, but cleaning straight away is still best practice to maintain a tidy finish.

Coverage

Coverage varies depending on wall thickness, drill spacing, hole depth and substrate type. Use the coverage table below for accurate planning and ordering, and ensure it reflects the 1L cartridge format and typical drilling centres of up to 120mm.

If the masonry is unusually porous, irregular, or thicker than expected, allow additional material and consider drilling from both sides where required.

Curing Time

Ultracure forms its hydrophobic barrier as it migrates and cures within the masonry. Final cure typically takes 2 to 6 weeks, depending on wall thickness, substrate porosity and site conditions. Walls may remain damp for a period after installation, particularly where hygroscopic salts are present or where the wall has been saturated for a long time.

For best results, allow injected walls to dry for as long as practical before replastering. A minimum waiting period of 14 days is commonly recommended before commencing salt management and replastering, but longer drying times are beneficial where programme allows. Good ventilation and stable background heat will support drying.

Finishing

Externally, drill holes can be finished by re-pointing with a matching sand and cement mortar to blend with existing masonry. Alternatively, you can use Universal DPC Injection Plugs to close and tidy the holes neatly, selecting the closest colour to suit the wall finish.

Internally, holes can be left open if the replastering specification is designed to stop short of the DPC line, or they can be filled as part of making good prior to finishing, depending on your chosen detailing. Ensure any finishing method does not bridge the DPC line, and keep the DPC level visible and consistent during the making good stage.

Decoration

Decoration should only take place after the wall has had sufficient time to dry and after salt-contaminated plaster has been addressed correctly. If salts remain in place, staining and finish failure can occur even when the DPC is functioning. Where replastering is required, use an appropriate salt-resistant system such as Wykamol Renovation Plaster or Wykamol Renderproof in line with a suitable specification.

Do not redecorate too early. Allow new plaster systems to cure and dry as instructed by the plaster manufacturer, and use breathable finishes where specified. Avoid impermeable wall coverings or coatings that can trap residual moisture unless the wall system has been designed for that purpose.

Cleaning

Clean spillages immediately. Wash contaminated surfaces promptly with warm soapy water. Keep tools and the outside of the nozzle clean during use to avoid build-up. Once cured, residues are difficult to remove and may require mechanical removal from tools or surfaces.

Limitations

Ultracure is designed to control rising damp by forming a chemical DPC barrier, but it does not resolve other damp mechanisms such as penetrating damp, leaks, condensation, or lateral moisture ingress below ground level. Bridging of the DPC by external ground, internal floor screeds, render, debris in cavities, or plaster taken below DPC level can compromise performance and must be addressed.

Walls heavily contaminated with hygroscopic salts often require removal and replacement of affected plaster. Without proper salt management, staining and damp appearance can persist even after the DPC is installed. In very thick walls, highly irregular masonry, or where access is only possible from one side, drilling strategy may need adjustment and in some cases drilling from both sides is necessary.

Other Information

Plan the full treatment line before drilling, including corners, party walls, changes in ground level, and any adjoining structures. Provide vertical DPC continuity where required to connect horizontal DPC lines and isolate untreated wall sections. Always keep the DPC height at least 150mm above external ground level wherever feasible, and as close to internal floor level as practical where solid floors are present.

If you are unsure whether the wall construction is solid, cavity, rubble-filled, or unusually thick, establish this before treatment so that hole depths and drilling strategy are correct. Rising damp control works best as part of a complete remedial package that includes moisture source control, correct DPC placement, salt management, and appropriate replastering and decoration.

Q) What is Ultracure Damp Proof Cream – 1 Litre Cartridge Kits and what are they designed to do?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are professional rising damp treatment systems that package Wykamol Ultracure silane-based cream with contractor grade application hardware. Each kit combines high capacity 1 litre Ultracure cartridges with a robust Cox Powerflow Cartridge Gun, a brass DPC injection nozzle and 12mm x 260mm SDS drill bits. The idea is to give installers a repeat use set up for injecting Ultracure cream into 12mm holes drilled along a selected mortar course at damp proof course level. Once injected, the cream migrates through the mortar and masonry pore structure and cures to form an in situ hydrophobic chemical damp proof course. This barrier stops further capillary rise of ground moisture while still allowing water vapour to diffuse, so the wall can dry out over time. When used as part of a full rising damp specification, including salt resistant replastering where required, Ultracure Damp Proof Cream – 1 Litre Cartridge Kits provide a long term, BBA certified solution for controlling rising damp in brick, block and many stone walls.

Q) How does the Ultracure Damp Proof Cream in the 1 Litre Cartridge Kits actually stop rising damp in masonry walls?

A) The Ultracure Damp Proof Cream in the 1 Litre Cartridge Kits uses silane chemistry to create a water repellent zone inside the wall. After you drill 12mm diameter holes at regular centres along the chosen mortar bed, the cream is injected with the Cox Powerflow gun and brass nozzle so that each hole is filled from the back to within about 10mm of the face. The cream stays in place within the bore due to its thixotropic nature, then gradually reverts towards a liquid phase and diffuses into the capillaries of the mortar and adjacent brick or stone. As it reacts with the mineral substrate, it bonds to the pore walls and forms a continuous hydrophobic band that repels liquid water. This prevents further capillary rise of groundwater while still allowing water vapour to escape, which is important so that the wall fabric can dry progressively rather than remaining sealed and saturated. Over time, moisture levels above the new chemical damp proof course fall and the symptoms of rising damp reduce, provided salts are managed correctly with appropriate replastering.

Q) What exactly is included in an Ultracure Damp Proof Cream – 1 Litre Cartridge Kit and how do the components work together?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are assembled so that contractors and competent DIY users receive a complete rising damp injection set up rather than just loose cartridges. Each kit includes one or more 1 litre Ultracure cartridges, a Cox Powerflow Cartridge Gun designed for repeated site use and a brass DPC injection nozzle that gives rigidity and reach into the drilled holes. To support proper drilling, the kit also contains 12mm x 260mm SDS drill bit or bits, which match the standard hole diameter and are long enough to reach the required depth in typical UK wall thicknesses. The Ultracure cartridge contains the silane cream that forms the damp proof course. The Powerflow gun extrudes the cream at a controlled rate, which is important with the higher capacity cartridges. The brass nozzle allows full depth insertion into each hole so they can be filled from the back outwards. The SDS drill bits ensure that holes are the correct size and depth for effective diffusion. Together, these components create a practical system that can be used again and again across multiple rising damp projects.

Q) In what types of buildings and situations should Ultracure Damp Proof Cream – 1 Litre Cartridge Kits be used?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are intended for use wherever rising damp has been correctly identified and a new chemical damp proof course is required as part of a planned remedial scheme. Typical projects include older brick and block homes that lack an effective original damp proof course, properties where the existing DPC has failed or become bridged by raised ground, screeds or renders, and traditional solid wall buildings that exhibit tide marks, flaking paint, blistered plaster and salt deposits near floor level. The higher capacity cartridges and contractor grade applicator make the kits particularly well suited to repeated remedial work, multi property programmes, long wall runs and commercial or social housing projects where efficiency matters. They can be used in both internal and external walls, provided the chosen DPC height is correct in relation to external ground and internal floor levels. Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are not designed to deal with condensation, penetrating damp, roof leaks or plumbing leaks, which must be addressed separately.

Q) What masonry types and wall constructions are suitable for treatment with Ultracure Damp Proof Cream – 1 Litre Cartridge Kits?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are suitable for most common masonry constructions where a horizontal damp proof course can be formed by drilling the mortar bed. These include solid brick walls, cavity brick walls, blockwork and many stone walls. In solid walls you drill a continuous line of 12mm holes along a chosen mortar joint, usually just above the internal floor finish and at least 150mm above external ground level wherever possible. In cavity walls you can either treat each leaf separately, drilling into the inner and outer leaves in turn, or drill through the inner leaf, across the cavity and into the outer leaf, provided the cavity is clear of debris and the method matches the specification. Random stone and rubble filled walls can also be treated, but they require careful survey and drilling so that the silane cream reaches a continuous course across the full thickness. In walls thicker than about 350mm it is often best to drill from both sides at corresponding heights. Where masonry is severely friable or structurally unsound, structural repairs or alternative approaches may be required in addition to Ultracure.

Q) How should I prepare the wall and select the correct DPC height before using Ultracure 1 Litre Cartridge Kits?

A) Preparation and correct DPC positioning are critical when using Ultracure Damp Proof Cream – 1 Litre Cartridge Kits. First, confirm that rising damp is the primary defect by ruling out leaking pipes, overflowing gutters, bridged cavities and obvious penetrating damp. Put right any external maintenance issues so that water is controlled at source. Next, choose the height for the new damp proof course. This should normally be at least 150mm above external ground level where practical and as close as possible to the internal finished floor level on solid floors. On suspended timber floors, the DPC is often positioned in line with or just below the joist ends bearing into the wall. Internally, remove skirting boards and plaster as necessary to expose the chosen mortar bed, stripping salt contaminated plaster to at least 300mm above the highest visible sign of damp. Check for embedded timbers at low level and specify repairs if decay is present. For cavity walls, ensure the cavity at DPC level is clear of debris to avoid bridging. Once these steps are complete, mark the drill line along the selected bed so that you maintain a consistent DPC level around corners and through changes in wall thickness.

Q) What drilling pattern, hole depth and spacing should I use with Ultracure Damp Proof Cream – 1 Litre Cartridge Kits?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are designed to follow the standard Ultracure drilling pattern. Using the supplied 12mm x 260mm SDS drill bit, drill horizontal holes into the selected mortar bed at centres not exceeding 120mm. The depth of each hole should be approximately 90 percent of the wall thickness. For a typical 115mm half brick wall you drill to about 100mm. For a 230mm solid brick wall the drill depth is around 210mm. For walls about 345mm thick, drill to roughly 320mm, and for walls around 460mm thick, drill to about 430mm. Where the thickness falls between these values, calculate the depth on a simple proportional basis. In very thick or irregular walls, drilling from both sides is often necessary to ensure complete coverage through the section. Keep the drill line level and continuous, and ensure that holes intersect the base of vertical perpends so that the barrier extends through the joints. Remove dust from each hole with a blow pump or vacuum before injection, because clean bores improve contact between the Ultracure cream and the mortar.

Q) How do I apply Ultracure Damp Proof Cream from the 1 Litre cartridges using the Cox Powerflow gun and brass nozzle?

A) Applying Ultracure Damp Proof Cream with the 1 Litre Cartridge Kits is straightforward once the drilling is complete. Load a 1 litre Ultracure cartridge into the Cox Powerflow Cartridge Gun, ensuring it is seated correctly and the drive rod engages fully. Pierce the metal film at the top of the of the Ultracure cartridge and screw the brass DPC injection nozzle securely to the cartridge. Insert the brass nozzle fully to the back of the drilled hole so that it reaches the correct depth. Begin squeezing the trigger to start extrusion, then slowly withdraw the nozzle while maintaining a steady trigger pressure so that the bore fills from the rear towards the face. Aim to fill each hole to within about 10mm of the surface, leaving a small void at the front. This technique helps to avoid air pockets and ensures that the Ultracure cream is placed where it can diffuse effectively into the mortar and masonry. Work systematically along the treatment line, checking visually that each hole is filled to a consistent level. If any holes appear under filled, top them up immediately rather than leaving gaps in the damp proof course.

Q) How can I estimate coverage and the number of Ultracure Damp Proof Cream – 1 Litre cartridges needed for a project?

A) The coverage of each Ultracure Damp Proof Cream – 1 Litre cartridge depends mainly on wall thickness, hole spacing and the depth of the drilled holes. To make a project specific estimate, first determine the total length of wall to be treated and calculate the number of holes required at a maximum spacing of 120mm. Next, determine the drill depth from the wall thickness, usually around 90 percent of the section. You can then approximate the volume of each hole from the 12mm diameter and the depth and multiply by the number of holes to find the total injected volume. Divide that figure by 1,000 millilitres to estimate how many 1 litre cartridges are required. In practice, most contractors rely on Wykamol’s published coverage data, which gives indicative treated metre lengths per litre for standard wall thicknesses. Whatever method you use, always allow extra capacity for wastage, variations in wall construction and any re drilling that might be needed if holes collapse or become blocked. Having sufficient Ultracure on site from the outset helps avoid breaks in the injection line and ensures continuity of the new chemical damp proof course.

Q) How long does Ultracure Damp Proof Cream from the 1 Litre Cartridge Kits take to cure and when will the wall start to dry out?

A) After injection from the Ultracure Damp Proof Cream – 1 Litre Cartridge Kits, the silane cream begins to migrate and react within the masonry almost immediately. The formation of the hydrophobic zone takes place over several days, with typical full cure in the range of two to six weeks depending on wall thickness, porosity, dampness and environmental conditions. However, this curing period is only the first stage. Drying of the wall fabric above the new chemical damp proof course takes longer because existing moisture and salts must be redistributed and evaporated. In moderately damp solid walls, visible improvement may be noted after a few months, although complete drying can take six to twelve months or more, especially if walls have been heavily saturated for years. During this period, good ventilation and background heating are important, as they help move moisture to the room air rather than trapping it in the structure. Decorations and plaster should be chosen to suit the drying regime and should not be applied until the replastering system has cured and the wall shows steady improvement.

Q) Why is salt resistant replastering so important after installing Ultracure Damp Proof Cream – 1 Litre Cartridge Kits?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits stop additional water rising through capillary action, but they do not remove the hygroscopic salts that have accumulated in the masonry and plaster as a result of long term dampness. These salts can attract moisture from the atmosphere even when the masonry below is drying out, leading to persistent staining, paint blistering and surface damp patches. To prevent this, salt contaminated plaster and render must be removed to at least 300mm above the highest visible tide mark and replaced with a salt resistant replastering system. Wykamol Renovation Plaster or Wykamol Renderproof are examples that are formulated to isolate residual salts from the internal finish while still allowing controlled moisture movement. If this step is omitted and ordinary plaster is applied directly over contaminated areas, it is very likely that the new finish will fail despite the Ultracure damp proof course functioning correctly. Salt management is therefore an integral part of any rising damp treatment specification rather than an optional extra.

Q) Can Ultracure Damp Proof Cream – 1 Litre Cartridge Kits be used effectively in basements and lower ground floor areas?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits can be used to control rising damp in basement and lower ground floor walls, but they should be integrated carefully into a wider waterproofing strategy. Rising damp is only one moisture pathway in these environments. Lateral penetration of groundwater through retaining walls and floor slabs is also common and is not solved by a horizontal chemical damp proof course alone. In many basement projects Ultracure is installed at, or just above, floor level to deal with capillary rise, while separate tanking systems or cavity drain membranes are used to address lateral ingress in line with BS 8102 guidance. The DPC line still has to be located at least 150mm above external ground level where possible, or combined with internal tanking where external levels are fixed. Before using Ultracure Damp Proof Cream – 1 Litre Cartridge Kits in a basement, it is sensible to obtain a professional survey so that the causes of damp are correctly identified and the chemical DPC is integrated into a complete, robust design.

Q) Are Ultracure Damp Proof Cream – 1 Litre Cartridge Kits suitable for competent DIY users or should they be reserved for professional contractors?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are primarily aimed at professional contractors and regular damp proofing teams because of the larger cartridge size and durable Cox Powerflow gun, although competent DIY users can also use them where they have the necessary tools and understanding. The physical tasks involved drilling 12mm holes in a straight line, handling a heavy duty cartridge gun, and injecting the cream are straightforward for someone comfortable with masonry work. The more challenging aspects are accurate diagnosis of rising damp, correct positioning of the new chemical DPC, appropriate drilling patterns for complex or mixed wall constructions and the specification of salt resistant replastering. For simple, clearly defined rising damp problems in standard brick walls, an experienced DIY user following the manufacturer’s instructions can often use Ultracure successfully. In more complex situations, or where the property owner is unsure of the cause or extent of dampness, advice from a qualified damp and timber surveyor or a specialist contractor is strongly recommended.

Q) What health and safety precautions should I follow when using Ultracure Damp Proof Cream – 1 Litre Cartridge Kits?

A) When using Ultracure Damp Proof Cream – 1 Litre Cartridge Kits you should follow normal construction site safety procedures as well as the product specific guidance. Always read the label and Safety Data Sheet before starting work. Wear suitable gloves, such as nitrile gauntlets, to protect your hands from the cream and from dust and sharp masonry edges. Use appropriate eye protection when drilling and injecting, since there is a risk of debris or splashes. A dust mask or suitable respiratory protection is important when drilling into brick or mortar, particularly in confined spaces, as masonry dust can be harmful if inhaled. Keep the work area tidy and free from trailing leads or loose rubble so that you can move safely along the treatment line. Ensure good ventilation, especially in basements and small rooms. Avoid eating, drinking or smoking while handling the product and wash hands thoroughly after use. If cream contacts skin, wash off promptly with soap and water. If it contacts eyes, rinse with clean water and seek medical advice if irritation continues. Keep cartridges and tools out of the reach of children and store them safely when not in use.

Q) How should I store Ultracure 1 Litre cartridges and look after the Cox Powerflow gun and brass nozzle between jobs?

A) Proper storage and maintenance help ensure that Ultracure Damp Proof Cream – 1 Litre Cartridge Kits remain reliable over multiple projects. Store 1 litre cartridges in a cool, dry place away from frost and direct sunlight, ideally upright and within the temperature range specified on the packaging. Avoid leaving cartridges in very hot vehicles or damp conditions. After use, release the pressure on the Cox Powerflow Cartridge Gun so that the drive rod is not left under load and wipe off any excess cream from the gun and brass nozzle. If a cartridge is only partly used, leave the nozzle attached or fit an appropriate cap to limit air ingress and store the cartridge upright for later use within its shelf life. The brass nozzle should be kept as clean as possible externally, since any hardened residue on the outside can affect insertion into the holes. The supplied 12mm x 260mm SDS drill bit should be brushed free of dust and stored dry to minimise corrosion. Periodic checks on the gun mechanism, especially the trigger and plunger, will ensure smooth operation and consistent extrusion on future jobs.

Q) What advantages do Ultracure Damp Proof Cream – 1 Litre Cartridge Kits offer compared with smaller cartridges or pump based systems?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits offer several advantages in terms of productivity and control. The larger 1 litre cartridge format means longer runs between reloads, which is particularly useful on extended walls and multi room projects where frequent changing of cartridges would slow progress. The Cox Powerflow gun is designed for high thrust and smooth extrusion, so even as the cartridge empties you can maintain consistent flow without excessive effort. The brass injection nozzle gives superior rigidity and reach compared with plastic nozzles, which helps with accurate full depth backfilling of holes and reduces the risk of bending or misplacement in harder mortar beds. Compared with liquid pump systems, the cartridge and gun method avoids high pressure, reduces mess, eliminates the need for pump flushing and is easier to set up for smaller or repeated jobs. At the same time, the Ultracure silane cream technology still provides performance comparable with traditional chemical DPC injection when installed correctly, supported by BBA certification.

Q) What limitations should I be aware of when specifying or using Ultracure Damp Proof Cream – 1 Litre Cartridge Kits?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are highly effective for rising damp control, but they are not a universal solution for all damp problems. They are specifically intended to form a horizontal chemical damp proof course in masonry. They do not address penetrating damp from rain soaked walls, defective roofs or gutters, plumbing leaks, or condensation caused by lifestyle and ventilation issues. Their performance also depends on correct drilling depth, spacing and continuity. If holes are omitted, misaligned or too shallow, sections of wall may remain untreated and rising damp can bypass the barrier. Bridging above or around the new damp proof course by external renders, internal screeds, debris filled cavities or very high external ground levels can also compromise their effectiveness. In very thick, random rubble or unusually constructed walls, diffusion of the cream can be more complex and may need special drilling strategies or supplementary measures such as internal membranes. Finally, Ultracure does not remove salts already present. Without salt resistant replastering or other salt management, staining and decorative failure can still occur on internal finishes.

Q) How do Ultracure Damp Proof Cream – 1 Litre Cartridge Kits integrate with damp proof membranes and other Wykamol systems?

A) Ultracure Damp Proof Cream – 1 Litre Cartridge Kits are designed to work alongside other Wykamol damp control and waterproofing systems to create a complete remedial package. In a typical rising damp project, the Ultracure chemical DPC is installed first at the correct height in the wall. Salt contaminated plaster is then removed and replaced with a salt resistant replastering system such as Wykamol Renovation Plaster or Renderproof to control residual salts and provide a stable base for decoration. In more challenging situations, for example where walls are very contaminated or where there is a risk of lateral damp as well as rising damp, a studded damp proof membrane can be fixed to the internal face of the wall after injection. This creates a physical barrier and a cavity into which moisture can dissipate, with plasterboard or plaster applied over the membrane to create the final finish. In basements, Ultracure injection may be combined with cavity drain membranes and sump systems to meet BS 8102 requirements. The key principle is that Ultracure tackles the rising water pathway while membranes and replastering manage salts and lateral moisture and provide a dry internal surface.

Q) What certification and service life does Ultracure Damp Proof Cream used in the 1 Litre Cartridge Kits offer?

A) The Ultracure Damp Proof Cream used in the 1 Litre Cartridge Kits is supported by BBA Certification, specifically Certificate No. 02/3961. This certification confirms that Ultracure has been independently assessed and found suitable for use as a remedial chemical damp proof course when installed in accordance with the manufacturer’s instructions and relevant British Standards such as BS6576. One of the key aspects of this certification is the stated long term performance. Ultracure is designed to remain effective for at least 20 years under normal service conditions once it has cured within the masonry. This aligns with typical expectations for refurbishment and provides reassurance to surveyors, landlords, local authorities and property owners that it is an appropriate long term remedy for rising damp. Of course, ongoing effectiveness also depends on good maintenance practice, including control of external ground levels, sound rainwater goods, unbridged cavities and appropriate internal finishes.

Q) What general best practice should I follow when planning a rising damp project with Ultracure Damp Proof Cream – 1 Litre Cartridge Kits?

A) When planning a rising damp project with Ultracure Damp Proof Cream – 1 Litre Cartridge Kits, start with a proper damp diagnosis so that rising damp is clearly distinguished from other moisture sources. Once rising damp is confirmed, plan the damp proof course position so that it is at least 150mm above external ground level and correctly related to internal floor levels, and ensure continuity around corners and through changes in level. Prepare the wall by addressing external defects, removing skirtings and salt contaminated plaster and checking low level timbers. Drill 12mm diameter holes at no more than 120mm centres to approximately 90 percent of wall thickness, using the supplied SDS bits, and keep the drill pattern consistent. Use the Cox Powerflow gun and brass nozzle to backfill each hole from the rear, filling to about 10mm from the face. Allow injected walls as long as practical to dry before replastering, then reinstate finishes using appropriate salt resistant plaster systems. Throughout, follow BS6576 guidance and Wykamol’s technical literature and seek specialist advice where construction is complex or the source of damp is uncertain. When these best practice steps are observed, Ultracure Damp Proof Cream – 1 Litre Cartridge Kits provide a reliable and efficient method for controlling rising damp in a wide range of masonry buildings.
