Product Description

HydroBlock WB is an alkali-resistant, modified silane-siloxane based, impregnating agent that penetrates well into the substrate. High “water-pearling” effect. Allows water vapour coming from inside the structure to pass through. Reduces salts moving to the surface of the structure. Does not form a superficial film. Reduces the growth of algae and green discolouration. Prevents frost damages. HydroBlock WB is used on façades, floors in e.g. warehouses, roofs of fibre cement, concrete and clay, paving stones and other materials of mineral origin, such as bricks, sand-lime bricks, mortar, sandstone, granite, and mineral plaster/render.
