SHOP / PRIMER / 100% SOLIDS MOISTURE VAPOR BARRIER PRIMER
Our Moisture Vapor Barrier Primer is a two-part, 100% solids primer that seals damp or moisture-prone concrete before you coat, so moisture rising through the slab can't push up and delaminate your floor down the road. It's the insurance coat for basements, newer slabs, and any ground-level concrete where moisture is a question mark. Roll it on first, then build your epoxy or polyaspartic system on top. Each 2 gal kit covers approximately 300 SF.
