Dow Corning ® 777 Water Repellent is a water-dilutable solution of
potassium methyl siliconate designed to impart water repellency to a wide variety of surfaces. Supplied at a concentration of 40 percent in water, Dow Corning 777 Water Repellent is usually diluted to a concentration of 3 percent or less before application. The siliconate reacts with carbon dioxide in the air to form an insoluble water- resistant treatment within 24 hours.
Water repellent for masonry surfaces
