They are resistant to Acid Rain and provide a degree of Water and Stain resistance. Furthermore, as silicates are alkaline, they are natural biocides. Because silicate-based coatings chemically bond to the surface, they help fill the pores of stone and cement materials providing a weatherproof surface and allows many years before recoating is necessary. Zaclon LLC produces several grades of Potassium Silicate. Typically, we recommend our Zacsil 30 Grade, a 2.5 weight ratio Potassium Silicate for use in masonry coatings. In addition, Zaclon LLC represents our Swiss based partners, van Baerles Inocot series of modified Potassium Silicates. The Inocot series of products provide enhanced stability and formulating flexibility. The use of silicate
