Red Devil’s 100% Silicone Shield Kitchen & Bath Sealant is a premium quality spec-compliant sealant formulated for kitchen & bath applications that can be exposed to water in 1 hour. Use on Sinks, Tubs, Showers, Toilets, Backsplashes, Countertops, Vanities & Fixtures, and even makes a great adhesive for loose tiles. The sealant is non-corrosive and will not crack, peel or shrink. For best application, remove any old caulk first with a razor blade, as silicone doesn’t adhere to itself or other sealants; clean and dry the surface before applying the sealant for a tight adhesion. Cut the nozzle/spout at a 45-degree angle for desired bead size. Please note that the silicone sealant is not paintable, so be sure to complete the painting of the surface prior to sealant application.
