FP MOISTURE VAPOR BARRIER FAST CURE 801

Moisture Vapor Barrier 801 FC is a fast-curing, two-component epoxy primer designed to reduce moisture vapor transmission through porous concrete. Its low-viscosity formula penetrates deeply into the substrate, promoting superior adhesion while creating a durable moisture-blocking barrier.

Ideal for concrete with elevated moisture levels, 801 FC controls moisture vapor emissions up to 25 lbs. per 1,000 sq. ft. per 24 hours and up to 99% relative humidity. It can be used beneath epoxy, polyaspartic, polyurethane, terrazzo, carpet, vinyl tile, wood flooring, and other moisture-sensitive flooring systems.
