Water repellent for masonry surfaces
XIAMETER™ OFS-0777 Siliconate 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, XIAMETER™ OFS-0777 Siliconate 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.
