Moisture Vapor Protection, Anti-fracture and Noise Reduction Membrane. 5 gallon pail.
MVP4® Moisture Vapor Protection is a one-part, trowel applied, elastomeric, moisture cure urethane membrane designed to be used beneath glue-down installations of engineered, solid and bamboo hardwood flooring with Bostik’s Best®, BSTTM, EFA+TM, or TKO® adhesives. MVP4 is designed to reduce moisture vapor transmission from the subfloor, create a noise reduction barrier over the substrate, and establish an anti-fracture membrane that can bridge cracks that can occur in the substrate prior to or after installation (up to 1/8″).
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, gypsum concrete and terrazzo.
MVP4 contains Bostik’s BLOCKADETM 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.
MVP4 independently tested in a controlled laboratory environment to measure the IIC (Impact Insulation Class) according to ASTM E492-04 and E989-89 and STC (Sound Transmission Class) according to ASTM E90-04 and E413-04 standards installed with 9/16″ thick engineered wood flooring over a 6″ concrete sub floor with a 5/8″ suspended gypsum ceiling, achieved an IIC = 62 and a STC = 61, with no suspended ceiling, IIC = 49 and STC = 52.
