Sodium Methyl Siliconate

SiSiB® WR0772 Siliconate is a nonflammable, water-dilutable solution of sodium methyl siliconate (Sodium 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 penetrating sealer 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.
