Terra Cotta Glaze is a non-yellowing, water-based, acrylic coating that highlights the natural color of masonry by providing a clear, semi-gloss sheen. The treatment does not alter the natural texture of the surface, nor significantly affect the vapor transmission qualities of the substrate. Terra Cotta Glaze provides a durable finish to terra cotta and masonry surfaces. See full details here.
Cathedral Stone Products has developed a Potassium Silicate Coating for use on all masonry (mineral surfaces). Similar coatings have been used in Europe for over 160 years and are now produced in North America. Cathedral Stone’s Potassium Silicate Coating combines the advantages of silicate/mineral and silicone coatings. Unlike latex and acrylic coatings, Potassium Silicate Coating forms a molecular bond with the masonry substrate. See full details here.
