FX-409 Moisture Vapor Barrier Epoxy Coating – USA
FlexRock FX-409 Moisture Vapor Barrier Epoxy Coating is a high-performance, two-part epoxy sealant designed to control excessive moisture vapor emissions in concrete substrates. This 100% solids epoxy system effectively reduces vapor emission rates up to 20 lb/24 hr/1000 ft², making it ideal for preparing floors ahead of the installation of vinyl sheets, VCT tiles, cementitious overlays, terrazzo, carpet, wood veneers, or resinous flooring systems.
FX-409 is formulated to meet ASTM F3010 requirements for vapor permeance when applied at the recommended thickness, ensuring long-term durability and compliance with industry standards.
Perfect for use on interior horizontal concrete surfaces in commercial, industrial, and institutional settings, this barrier prevents moisture-related failures in flooring systems and enhances coating adhesion.
Proudly manufactured in the USA and available for nationwide distribution.
