Masonry Aquashield WB is a water borne silane / siloxane solution used to impregnate masonry to make it water-repellent. Limited water repellence will develop within 24 hours. Maximum water repellence will be achieved within 3 – 7 days of treatment. Masonry treated with Masonry Aquashield WB will be protected from moisture absorption and the resulting damage that can occur as a result of dirt retention, the growth of fungi, algae, moss and lichen. The pores in the treated masonry remain open allowing high permeability or "breathability". As Masonry Aquashield WB is a treatment, not a film, the appearance of the treated masonry remains unchanged, without any surface residue. Masonry Aquashield WB is NOT suitable for use on limestone, rather, it is recommended that Limestone Aquashield WB be used.
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.
