Richard's Bond-Crete Silicone/Acrylic Concrete Stain is a durable pigmented masonry waterproofing stain designed to penetrate into unpainted and/or unsealed cementitious surfaces. Its special formulation of solvents, acrylic resin, silicone and color pigments add long lasting beauty to the surface. It helps to seal the surface fully protecting it from powdering, staining and moisture penetration. It dries fast, has a low sheen to minimize slipping, provides excellent weather resistance, wear resistance and offers superior color retention. It may be applied to surface areas coated with a similar concrete stain type product, but is not recommended for application over any other existing paint coatings. Available in 500 White Canvas; 500-DB Deep Base; 500-AC Accent Base; and 10 stock colors. For exterior use.
