Dow Tub, Tile & Ceramic silicone sealant (formerly Dow Corning Tub, Tile & Ceramic silicone sealant) is a one-part, acetoxy-cure, RTV silicone that cures to 100% silicone rubber. This fast cure, high strength silicone caulk is ideal for non-porous surface applications requiring a silicone sealer that is mildew-resistant after it becomes cured. Dow Tub, Tile & Ceramic silicone sealant can be used as an adhesive, sealant, and grout for ceramic tile and provides for a watertight seal of bathtubs, shower enclosures, vanities, counter tops, lavatories, faucets, saunas, hot tubs, plumbing fixtures, drains, piping, shower enclosures, and other nonporous surfaces. This silicone caulk becomes tack-free in 15 - 20 minutes, keeps its flexibility for very long periods and will not become brittle, crack or shrink like some of the store bought caulk brands. This excellent silicone sealant is perfect for applications in bathrooms and kitchens where moisture prevails.
