CCS™ Coating, MVR Primer is a versatile high-performance, two-component, solvent free, epoxy designed for prime coating dry and damp slab on grade concrete floors where moisture vapor transmission rates exceed 32lbs./1000ft. over a 24 hr. period as measured by ASTMF1869. Typical applications include preparing for the installation of impervious floor coatings and coverings both above and below grade. MVR Primer reduces excessive moisture vapor transmission rates of up to 15 lbs./1000 ft. over a 24 hr. period to below 3 lbs. to meet the requirements of impervious flooring manufacturers.
