  Two-component coating system

The two-component coating system from Madewell Products Corp. consists of a high-build restoration mortar and a 100 percent solids epoxy corrosion barrier coating that is ideal in repairing and protecting concrete and brick sewer structures. First, the mortar is shot onto a damp substrate, using the water on the surface to achieve a strong bond. Then an epoxy topcoat is applied while the mortar is still soft, and the two materials cure together. The final product results in a strong and highly corrosion-resistant monolithic lining that provides a continuous surface. The mortar and topcoat are tightly bonded to the substrate and each other. This system saves time and labor costs because it eliminates the need to dry the structure prior to mortar application. The need for a second mobilization to apply the epoxy after the mortar has cured is also eliminated because the two materials cure simultaneously. 800/741-8199; www.madewell.net.
