Impervitite is a strong epoxy floor patch that has four times the compressive strength of concrete. It provides excellent protection against steel-wheeled traffic and offers chemical resistance to oil, water and solvents even at a thin featheredge. Because it is solvent-free, Impervitite has no strong odors or flammability hazards that are common problems with other conventional epoxy patches. To use, simply mix the two components together, apply and trowel smooth. Impervitite dries quickly and smoothly in just 4-6 hours for regular traffic. Each unit covers 50 sq. ft. at 1/8-in. thickness.
