MVP Moisture Vapor Protection
MVP4® Moisture Vapor Protection is a one-part, trowel applied, elastomeric, moisture cure urethane membrane designed to:
1) Reduce moisture vapor transmission from the subfloor;
2) Create a noise reduction barrier over the substrate;
3) establish an anti-fracture membrane that can bridge cracks that can occur in the substrate prior to or after installation (up to 1/8"); prior to the installation of engineered and solid hardwood flooring with Bostik’s Best®, BST®, EFA®, Ultra-Set® Hardwood or Fast Tack® adhesives. MVP4 may be used over all substrates common to hardwood flooring installations including: concrete, plywood, particle or chip board (underlayment grade), well bonded vinyl, ceramic tile, cement backer board, cement patch/underlayments, radiant heat flooring, and terrazzo.
4) MVP4 contains Bostik BLOCKADE™ antimicrobial protection which inhibits the growth of bacteria, mold or mildew on the surface of the dried membrane; the dried membrane resists stains caused by mold.
