Sika Water Seal 5L Solvent Based Masonry Waterproofer

Buy the Sika Water Seal 5L from Wow Tools for long-lasting, professional protection against rain, damp, and frost on external masonry. This solvent based liquid waterproofer penetrates deep into the surface, lining the pores with a water-repellent coating while allowing the wall to breathe naturally. It provides durable protection without significantly changing the appearance of brickwork, stone, or concrete.

Designed specifically for vertical surfaces, Sika Water Seal penetrates to a depth of up to 5mm, helping to prevent water ingress, frost damage, efflorescence, and surface spalling. By reducing rain and damp penetration, it also helps preserve the natural heat-insulating properties of the wall. In urban and industrial environments, it offers added protection against acidic atmospheric conditions and smoke-related discolouration, keeping masonry cleaner for longer. When applied correctly, protection can remain effective for up to 10 years, depending on substrate and exposure.
