Chem-Proof – Moisture Vapor Barrier Epoxy Coating (3 Gallon Kit)

Chem-Proof is a professional-grade, two-component 100% solids epoxy moisture vapor barrier engineered specifically for concrete floors with elevated moisture levels and high pH. Its low-viscosity formulation penetrates deeply into the concrete substrate — delivering superior adhesion and a more effective moisture seal than conventional epoxy flooring products in a single coat.

Suitable for both new and existing concrete floors, Chem-Proof is the critical first step in any floor coating system where moisture vapor transmission is a concern.

One-Coat Moisture Vapor Barrier

Chem-Proof is formulated as a one-coat moisture vapor barrier, simplifying the preparation stage of floor coating projects. A single application at the recommended thickness seals and blocks moisture vapor transmission — creating a stable, dry substrate for epoxy, polyaspartic, or polyurethane topcoat systems.

Low Viscosity for Deep Concrete Penetration

The low-viscosity formula flows into the pores and capillaries of the concrete substrate, achieving deeper penetration and stronger mechanical adhesion than higher-viscosity alternatives. This enhanced penetration is critical for long-term coating performance on slabs with elevated moisture or high pH readings.
