CMS moisture vapor reduction admixture was developed by a dedicated group of chemical engineers, concrete quality control professionals, and flooring experts to facilitate owners, architects, general contractors, and the entire project team to eliminate costly, inefficient, flawed moisture vapor emission testing and unnecessary topical moisture mitigation applications. To maintain demanding project schedules and to remain on budget. The product, CMS MVRA works in normal as well as lightweight concrete by restricting the integral capillary system and eliminating the route of moisture vapor emission movement out of the concrete.

As an admixture, it is integral to the concrete, not surface applied, it will not interfere with the bonding of adhesives suitable for non-porous substrates, resinous coatings roofing membranes or cementitious underlayments. In short…if it sticks to low porosity concrete, it sticks to CMS MVRA dosed concrete!
