MVP4® Moisture Vapor Protection
MVP4® is a one-part, trowel-applied moisture-cure urethane membrane that protects glue-down wood flooring installations from subfloor moisture. It also reduces sound transmission and bridges substrate cracks up to 1/8″.
MVP4® Features:
- Unlimited moisture vapor protection
- Noise reduction comparable to 1/4″ cork*
- Enables visual inspection before flooring install
MVP4® Applications:
- Under engineered, solid, and bamboo hardwood flooring
