A process for forming a protective layer on a rigid surface, such as a metal or wood surface, to provide protection against abrasion, corrosion, heat and fire. The process comprises first preparing the surface of the article. On metal articles, the surface can be prepared by cleaning the surface and then exposing the surface to concentrated phosphoric acid. On wood, the surface can be prepared by thoroughly cleaning the surface with hot water and detergent only. Preferably, the surface is prepared such that a uniform, continuous layer of liquid can be formed thereon. After the surface is prepared, a 10-16% (v/v) silicate-containing solution is then applied for 20 seconds and allowed to dry completely at 305.degree. F. to form a layer of silicate material over the surface. During the drying process, at least a portion of the sodium silicate is converted into silicon dioxide. An acid is then applied to the surface to form the protective layer on the surface.

Process for protecting a surface using silicate compounds

A process for forming a protective barrier on metallic or wood surfaces to provide protection against abrasion, corrosion, heat, and fire. The process is begun by first forming a fixed surface on the metallic or wood article. On metallic articles, the fixed surface is formed by cleaning the surface and then exposing the surface to concentrated phosphoric acid. On wood, the fixed surface is formed by thoroughly cleaning the surface with hot water and detergent only. After the fixed surface is prepared, it is then exposed to a 10-16% silicate salt for at least one minute and then allowed to dry completely at 305 degrees Fahrenheit to form a first layer of silicate salt over the fixed surface. During the drying process, a portion of the sodium silicate is converted into silicon dioxide. A plurality of sodium silicate layers are then formed over the first layer of sodium silicate. After the last layer of sodium silicate is formed, it is then exposed to concentrated phosphoric acid to form a bi-layer thereon comprised of an inner layer of sodium silicate and an outer layer of silicon dioxide. In an alternative method, each sodium silicate layer is exposed to concentrated phosphoric acid to create a plurality of bi-layers over the fixed surface.
