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 smaller the tile size, the more grout you will have. If you installed 1 tile, you're in for a lot of grout sealing; if it's 12 or 16 tile, not so much. This matters because using the brush or roller sealer applicators on an entire roomful of 1 sized tile can take up a whole weekend. In this case, try the spray on type of grout sealer.
