Patent ID: 8313809

Claim:
A process for providing a multi-layered structure which comprises the steps of: a) providing a substrate; b) coating said substrate with a first layer, said first layer comprising an aqueous dispersion of a coating material selected from the group consisting of: epoxy polymer coatings, polyurea polymer coatings, and urethane polymer coatings; c) coating said first layer with a second layer, said second layer being compositionally different from said first layer, and comprising an aqueous dispersion of a coating material selected from the group consisting of: epoxy polymer coatings, polyaspartic polyurea polymer coatings, polyurea polymer coatings, urethane polymer coatings and urethane-modified acrylic polymer coatings; and d) coating said second layer with a top layer material, said top layer material comprising an aqueous dispersion of a coating material selected from the group consisting of: polyaspartic polyurea polymer coatings, polyurea polymer coatings, urethane polymer coatings, and urethane-modified acrylic polymer coatings, said substrate being a concrete surface, and wherein said top layer is sufficiently cured to enable passage of a motorized vehicle over said substrate within twenty-four hours of initial application of said first layer to said substrate, said multi-layered structure not being damaged by such passage of said motorized vehicle over said substrate.
