Controlling Moisture Vapor in Concrete Prior to Gluing Down Wood Flooring

Monday, July 13, 2009
All concrete surfaces regardless of age or grade level will release some level of moisture vapor. Vapor retarders such as Bostik's MVP4 Moisture Vapor Protection has been extremely effective in controlling the rate of vapor transmission from the subfloor when used in conjunction with any approved Bostik Urethane Adhesive. Bostik’s MVP4, being the first one-part, polyurethane product in the market, currently is the only vapor protection product that does not require moisture testing prior to use and also does not have an upper limit! Once your concrete substrate is properly prepared, MVP4 is easily troweled on using a 3/16" x 5/32" V-Notch trowel and has virtually no odor. After a short cure time of 12 hours, you can begin installing solid or engineered wood flooring using Bostik's Best, TKO, BSTurethane or EFA+.
