Description
A liquid silicate that hydrolyzes to form a colorless, transparent film of Silica. For application, ethyl silicate is dissolved in an anhydrous ethanol solution. Small amounts of water will cause the solution to gel. Once applied, moisture from the atmosphere initiates irreversible hydrolyzation producing a solid silica film in less than an hour. Ethyl silicate was introduced as a paint vehicle in England in 1931 for painting outdoor murals. It is used with Alkali and Acid resistant Fresco pigments. The silicate colors are durable and resistant to weathering. More recently, ethyl silicate has been used for consolidating, strengthening and weatherproofing Stone, mortars, and cements.
