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.

One side of the polyethylene film extends beyond one edge of the polyethylene foam sheet. The laminate composition is installed in a free floating manner on the concrete subflooring, with the polyethylene film or the polyethylene foam sheet contacting the surface of the concrete subflooring. The laminate composition is usually in long strips, so when it is installed one edge of one strip overlies the extended portion of the polyethylene film of an adjacent strip. Then the laminate wood finish flooring, in plank form, is installed on top of the laminate composition in a free floating manner. The laminate wood planks fit together in a tongue-in-groove manner and are glued together.
