Vapor Prime is a specially formulated water-based epoxy primer designed to provide superior adhesion over concrete with high levels of moisture vapor emissions. When used in conjunction with the companion finish coating, 100% solids Vapor Prime, the result is a system that reduces moisture vapor emissions to acceptable levels and maintains its bond under continuously moist, alkaline conditions. In this situation, the system is suitable for concrete substrates indicating up to 99% RH when tested in accordance with ASTM F2170.
The product may be applied at temperatures between 40°-100°F. Vapor Prime has been formulated for low viscosity and excellent substrate wetting capabilities to promote penetration and adhesion. The special curing agent allows for adhesion to damp concrete. Vapor Prime is available in a fast cure version when faster turnaround is necessary. The product may be applied at temperatures between 40°-100°F.
