Potassium Silicate S32-MR

Potassium Silicate S32-MR coating is the most compatible paint for any masonry surface. Use on concrete, brick, limestone, brownstone, sandstone, and terra cotta. When applied directly to bare masonry, it delivers 92 % vapor permeability. This allows the substrate to breathe naturally while remaining completely colorfast. Unlike latex and acrylic coatings, this true mineral paint chemically bonds with the masonry at a molecular level for exceptional adhesion and longevity. This bonds prevents peeling, unlike paint. It combines the time-tested advantages of traditional silicate/mineral paints with the superior water-repellent properties of silicone technology, creating a durable finish that withstands extreme climate conditions and actively repels water. Dilute with Liquid Silicate and use as a mortar stain!  Note: While this coating can be applied over existing latex or acrylic paints, doing so may reduce its breathability and overall performance. Similar potassium silicate coatings have been trusted across Europe for over 160 years and are now being produced for the first time in North America.
