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.
