STONE SEAL is a stain proof product for compact natural stones, marbles, granites, Agglomerates honed or polished both for interior and for exterior. The product does not leave any film on the surface and keeps the natural permeability and colour of the stone unchanged. It protects floorings, coverings, kitchen tops, vanity tops, tables etc. from dirt, stains of oil, coffee, beverages, markers, paint, etc. STONE SEAL is a penetrating product; therefore it does not increase the resistance of marbles or stones containing carbonate against the acid aggression of wine, vinegar, lemon juice, tomato juice, cleaners, etc.
