  • Patent number: 8479472
    Abstract: A method and composition for reconditioning the inner surfaces of a facility. After removing loose material, corrosion and rust by abrading the surface, repairs are made to the surface. Gaps, cracks, and pits are filled and transitions from one surface material to another are smoothed with putties; holes and complex areas of the surface are filled with expanding foams and shaped to contour; and sheet metal is added where corrosion and rust have left extensive weakened areas in the surface. A corrosion inhibitor such as aluminum flakes or micaceous iron oxide is applied to the shaped surface followed by a structural coating of polyurea or elastomeric urethane and top coat of moisture cured urethane or polyaspartic acid that adds an additional water barrier and increases that surface shaping to shed water. The combination of these layers results in a surface with improved robustness against frequent cleaning.
