Masonry Stainshield WB combines the excellent durability of a premium acrylic emulsion with the water repellence of silicone, to provide a UV stable treatment for both interior and exterior use. Masonry Stainshield WB will protect a variety of inorganic substrates such as mineral building materials from moisture absorption, dirt retention, and common household stains. As Masonry Stainshield WB contains an active biocide, it will afford additional protection against fungi, moss, algae and lichen. It will also provide some binding properties to friable substrates, and dries to a matt or low sheen finish depending on the substrate porosity and the film build applied. Masonry Stainshield WB will provide excellent protection from most household and food stains, and is highly recommended for protecting concrete driveways from grease and oil staining.
