FP MOISTURE VAPOR BARRIER SLOW CURE 803

Moisture Vapor Barrier 803 SC is a two-component, slow-curing epoxy primer designed to reduce moisture vapor transmission through porous concrete. Its low-viscosity formula penetrates the substrate to promote strong adhesion while creating a durable barrier beneath moisture-sensitive flooring systems.

The extended working time makes 803 SC well suited for larger installations where contractors need additional time for mixing and application. It can be used beneath epoxy, polyaspartic, polyurethane, terrazzo, carpet, vinyl tile, wood flooring, and other compatible floor systems.
