SILACAST BES is a non-hazardous polymer emulsion designed to enhance and create a wet look to porous concrete surfaces such as concrete pavers, roof tiles, barrel tiles and natural stones. Unlike topical acrylic sealers SILACAST BES penetrates deep into the substrate enhancing the natural colors of the material. Topical sealers produce a film that reflects sunlight from the surface only appearing to enhance. Topical acrylic sealers are susceptible to UV Rays and can turn yellow and peel away from the surface. Topical sealers also require harsh chemicals to remove after a year or so before applying a new coat. SILACAST BES does not require stripping.
