Potassium Methyl Siliconate-1

SiSiB® WR0777 Water Repellent is a water-dilutable solution of potassium methyl siliconate (Potassium siliconate) developed to impart water repellency to a wide variety of natural stone and masonry surfaces. The siliconate reacts with carbon dioxide in the air to form an insoluble repellent surface and reduce water absorption within 24 hours.


This siliconate sealer for concrete is suitable for the surface of natural stone, like sandstone, limestone, and red brick, gray brick, granite, ceramics etc.; it is not suitable for polished or glazed surfaces.
