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 temperature of the tile and grout you are sealing must be between 50Â°F and 80Â°F (10Â°C to 26.6Â°C) at the time of application. Use grout sealer in a well-ventilated area. (If you are using an epoxy based sealer, then this will not be necessary.) Always wear gloves and use eye protection.
