A damp proof cream kit is usually the best option if you want the cream and key application equipment together in one purchase. Instead of buying the DPC cream, applicator, nozzle and drill bits separately, a complete damp proof cream kit helps make the job simpler, especially for DIY rising damp treatment, renovation work and first-time chemical DPC installation.

If you already have the correct damp proof cream applicator, 12mm SDS masonry drill bit and injection equipment, you may only need to buy the damp proof cream cartridge or tub on its own. However, if you are starting from scratch, a DPC cream kit can save time, reduce the chance of ordering the wrong accessories and help you begin the job with the correct basic setup.

For smaller domestic repairs, 380ml damp proof cream cartridge kits are a practical choice. They are well suited to short wall runs, localised rising damp problems and smaller masonry treatments where controlled hand application is preferred. These kits are ideal for homeowners, landlords and maintenance users who want a simple chemical damp proof course treatment without buying professional pump equipment.

For larger wall runs or repeated domestic work, 1L damp proof cream cartridge kits are usually more efficient. The larger cartridge size means fewer changes during application, while the correct DPC nozzle and drilling setup helps deliver the cream into 12mm mortar-bed holes more consistently. This makes 1L DPC cream kits a strong option for full-room treatments, renovation projects and longer sections of damp wall.

For trade users, multiple rooms, long wall runs or repeat damp proofing jobs, 5L damp proof cream kits are usually the most efficient option. These kits are designed for larger-scale rising damp treatment and are typically used with a suitable DPC injection pump or applicator system, helping deliver controlled, consistent injection across larger areas of brick, block or stone masonry.

A complete damp proof cream kit is especially useful if you are treating rising damp for the first time, working on a property renovation, or want to avoid missing essential installation items. For a proper job, you will still need to measure the wall, remove defective or salt-contaminated plaster where required, drill the correct pattern of holes, inject the cream at the right depth and re-plaster afterwards with a suitable salt-resistant plastering system.

To install damp proof cream correctly, you will need the right applicator, drill bit and finishing accessories. Chemical DPC cream is injected into a line of drilled holes in the mortar bed, so using suitable damp proofing tools helps keep the application cleaner, easier and more consistent.

For 380ml damp proof cream cartridges, a C4 Cartridge Gun is usually the simplest option. This setup is ideal for small domestic rising damp repairs, short wall runs and DIY damp proof course installation where controlled hand application is required.

For 1L damp proof cream cartridges, a suitable 1L cartridge gun and DPC injection nozzle should be used. A professional setup such as a Cox Powerflow Cartridge Gun with a brass DPC nozzle is ideal for longer wall runs, repeat remedial work and cleaner injection into drilled masonry.

For 5L damp proof cream tubs or larger trade jobs, a DPC injection pump is normally the better choice. Pump applicators such as the Osatu Tango 7 or Selecta 7 are suited to larger rising damp treatment projects, full-room applications and regular professional damp proofing work where speed and consistent dosing are important.

You will also need a 12mm SDS masonry drill bit to create the injection holes in brickwork, blockwork or stone masonry. The correct drill bit length will depend on the wall thickness, but 12mm SDS Plus drill bits are commonly used for damp proof cream injection because they create the correct hole size for most DPC cream systems.

Once the damp proof cream has been injected, DPC injection plugs can be used to seal the drilled holes. These help close the injection points after treatment and leave the wall neater once the injection stage has been completed.

If you are unsure whether to buy everything separately, a complete damp proof cream kit may be easier. DPC cream kits are designed to include the cream and key application equipment together, helping you avoid missing essential tools before starting your rising damp treatment.

Salt treatment and re-plastering are important parts of many rising damp repairs. A chemical damp proof course helps control rising moisture in the masonry, but old plaster can still contain hygroscopic ground salts that have been carried up through the wall over time. If these salts are left behind in defective plaster, they can continue to attract moisture, cause staining, damage decorations and lead to recurring damp patches on the internal wall surface.

Before injecting damp proof cream, defective or salt-contaminated plaster should normally be removed from the affected area where required. This helps expose the correct injection line, removes plaster affected by hygroscopic salts and allows the wall to be prepared properly before the new chemical damp proof course is installed.

Once the DPC cream has been injected, the masonry can then be treated with a suitable salt neutraliser where required, before being re-plastered with a salt-resistant renovation plaster or render system. This helps protect the new decorative finish and gives the wall a better chance of drying down correctly.

Wykamol Salt Neutraliser is a useful treatment for mineral building surfaces affected by salts caused by rising damp. It is designed to help neutralise salts absorbed into masonry and internal plaster, making it a practical add-on product when carrying out damp proofing repairs in older properties, renovations and remedial building work.

For re-plastering after DPC cream injection, Wykamol Renovation Plaster is a strong option where a breathable, salt-resistant finish is required. It is designed for use after damp-proofing work and helps reduce the risk of efflorescence, salt contamination and further damage to internal plaster finishes.

Where a sand and cement render system is preferred, Wykamol RenderProof can be added to cement renders to improve water resistance and help block residual ground salts. This makes it suitable for internal and external masonry following the insertion of a damp proof course, especially where a tougher render backing is needed before finishing.
For best results, always treat the full damp proofing job as a system rather than just injecting the cream. Damp proof cream, correct preparation, salt treatment and suitable re-plastering products work together to help reduce rising damp symptoms, protect internal walls and create a longer-lasting finish ready for decoration.

Damp proof cream is designed for treating rising damp in masonry walls. Rising damp usually starts low down on the wall and is caused by ground moisture moving upwards through brickwork, blockwork, stone or mortar. If your damp problem is linked to a missing, failed or bridged damp proof course, a chemical DPC cream can be used to form a new water-repellent barrier within the wall.

Damp proof cream is not the right treatment for every damp problem. If rainwater is soaking through external brickwork, stonework or render, the issue may be penetrating damp rather than rising damp. In this case, an external masonry water repellent or masonry waterproofing cream may be more suitable, helping protect porous walls from wind-driven rain while still allowing the surface to breathe.

If the internal wall surface is affected by ongoing damp, salt contamination or uneven masonry, a damp proof membrane system may be required before plastering or dry lining. Damp proof membranes create a barrier between the damp wall and the new internal finish, making them a useful option where the wall needs extra protection after damp proofing work.

If the issue is on floors, below-ground areas, retaining walls or surfaces where water pressure may be present, a liquid-applied damp proofing paint, tanking product or waterproof membrane may be a better choice than DPC cream alone. These products are designed for resisting water penetration on suitable walls and floors, depending on the structure and the level of moisture involved.

If the problem is black mould, streaming windows, musty air or damp patches on cold wall surfaces, the cause may be condensation rather than rising damp. In this case, anti-mould paints, anti-condensation coatings, ventilation products or moisture control solutions may be more suitable than a chemical damp proof course.

Before buying damp proof cream, check the pattern of moisture carefully. DPC cream is best used where there is clear evidence of rising damp at low level. For other damp problems, consider masonry water repellents, damp proof membranes, damp proofing paints, tanking systems, moisture meters or anti-condensation products to make sure you choose the correct damp proofing treatment for the job.
