Novel formulations of inorganic, chemically bonded, phosphate alumino silicate sprayable coatings are disclosed. The disclosed coatings retain all the positive attributes of similar coatings disclosed in recent patents on corrosion and fire protection, and in addition, provide, superior surface toughness and smoothness, better abrasion and acid resistance, less erosion and longer durability with zero flame-spread coatings on wood surfaces. Being pore-free, water cannot penetrate into these coatings. Unlike the previous inorganic oxide-based phosphate coatings, the glassy phase in these coatings provides a translucent and dense surface. The component pastes are smoother to pump, do not settle or harden during storage and transport, and in addition, do not exhibit pozzalinic properties.
