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.
Now I suggest to people to NOT SEAL grout. If you use Stain Solver, a Certified organic oxygen bleach, it will remove any stain from grout in minutes. After the grout is dry (three to five days), seal the grout with a silicone grout sealer. These products are available at your tile supplier. Be careful not to get these products on the tub or shower floor, as they are very slippery. The grout needs to be sealed, as it can and will absorb water.
