Colourless water repellent coating, water-based, natural and ecological, suitable to protect absorbent surfaces such as bricks, stoned, cement, etc... from wind driven rain infiltration.  It does not alter the colour of the masonry, it protects from ice, it blocks damp, it allows the evaporation of water and it can be used also on slightly wet materials.  Compared to traditional solvent-based solutions, our concrete sealer is a completely water based product, not dangerous for environment and health, both during application and curing.
