SIMIRON MVB is a 100% solids, two-component, epoxy primer designed for concrete floors with severe moisture vapor transmission (MVT) problems. SIMIRON MVB can control emission rates up to 20lb/24hr/1000 square feet. This primer is designed to be used as a moisture vapor barrier under SIMIRON decorative floor coatings along with other flooring systems.

Use either a flat or notched rubber squeegee and spread material to uniform thickness. As material is being spread, another applicator should immediately back-roll material with a 3/8” shed-resistant woven roller cover. DO NOT BACK-ROLL MATERIAL AFTER IT BEGINS TO TACK-UP.
