This Sika Water Seal is a sealant that stops water wear on brickwork, stone masonry, concrete, pebbledash and other exterior walls. The formula is solvent-free, making it more environmentally friendly by reducing pollution. Use it after clearing walls of any build-up of dirt or moss to achieve an effective and protective seal.
It can be applied with a garden spray, making it quick and easy to use. It even performs on damp surfaces so you don't need to wait for dry weather. The product is clear and translucent, ensuring that it won't change the colour of your home's exterior finish. It also has improved water-beading compared to solvent sealants, which stops run-off and creates an evenly-coated seal. The hydrophobic formula will resist rain and moisture leaks, preventing it from entering the wall and wearing the surface.
