SurfiSeal is a brick or masonry sealant that is an emulsion of siloxane. This product comes ready to use, and penetrates into concrete to provide long-term protection, lasting many times longer than conventional coatings. The invisible film that forms will “bead” loose water and provide protection against de-icing salts and chloride ions. For added safety SurfiSeal will not change traction or skid resistance of a surface.
