Sika Damp Proofing Slurry is a polymer modified cement-based waterproof coating designed for damp-proofing and tanking applications on concrete and masonry substrates. Supplied as a single component powder, it is mixed with water on site to produce a brushable, trowelable, or spray-applied slurry suitable for internal and external use.
The product is formulated to protect structures against water ingress, rising damp, and moisture penetration. It is commonly used in cellar tanking and below ground waterproofing systems, including retaining walls, lift pits, and floor slabs where a continuous barrier is required.
Sika Damp Proofing Slurry is suitable for cellar walls, foundation walls, retaining structures, and concrete floor slabs where protection against moisture is required. It can also be used in water-retaining structures such as tanks and planters when applied in accordance with installation guidance.
The slurry is mixed with clean water to achieve the required consistency depending on the application method. Surfaces should be clean, sound, and dampened before application. It is typically applied in two coats, with each coat worked in opposing directions to ensure full and consistent coverage.
When applied correctly, the coating forms a dense, continuous waterproof barrier that resists moisture penetration. Coverage will vary depending on substrate condition and method of application, with multiple coats required to achieve full performance.
Suitable for domestic and commercial construction, Sika Damp Proofing Slurry provides a durable solution for cellar tanking and below ground waterproofing. It is designed to form a continuous protective layer when installed correctly, supporting long-term resistance to damp and water ingress.
