The Color Sealer is an Acrylic Resin that has a chemical reaction with the grout that hardens in the pores and dries to a natural look and feel. The constant acting mildicides provide a sanitary grout line surface. It colors and seals in 1 bottle. Easily wipes off tile surface when applying.
The cloth can be dampened with warm water to remove dried sealant. Unlike liquid grout sealers, spray grout sealers can be removed right after application. Make sure that you never apply grout sealer to the surface of an unglazed tile. It will never come out of the tile.
