BK-AquaPhobe is a colorless hydrophobic impregnation based on silane and siloxane, intended for both outdoor and indoor use. It can be applied as a finish or as an additive to cement mixtures to enhance the hydrophobic properties of the material. It is recommended for impregnation of mineral and synthetic facade renders, bricks, tiles, natural stone, concrete surfaces, grout compounds, and similar materials. This product is designed to protect mineral surfaces from excessive water absorption and aggressive airborne chemicals that can damage and degrade the appearance of buildings and monuments. It also reduces the occurrence of efflorescence on mineral surfaces and minimizes the likelihood of microorganisms and moss developing on shaded areas of facades.
