Sikagard®-790 All-in-One Protect is a protective impregnation designed to protect ALL types of porous mineral substrates from the penetration of water-based liquids and oils, and to prevent or significantly reduce the stains caused by them. Sikagard®-790 All-in-One Protect does not create a film on the surface and is therefore completely invisible. Sikagard®-790 All-in-One Protect allows vapor diffusion in both directions, resulting in treated surfaces maintaining their usual, healthy, hygrothermal behavior. Sikagard®-790 All-in-One Protect also makes it easier to remove graffiti sprayed on the surface (using appropriate cleaners).
