Moisture and vapor barriers protect flooring installations from subfloor moisture and water-vapor transmission. Whether you need a liquid moisture-vapor barrier for concrete slabs, a roll-on primer, or 6-mil polyethylene sheeting under laminate and floating floors, this collection has professional-grade options for Honolulu and across Hawaii.

A vapor barrier (also called a moisture barrier) controls the movement of water vapor through floors and walls, protecting against mold, rot, and adhesive failure. Installed over concrete slabs or beneath floating floors, a high-quality moisture vapor barrier is an essential part of any subfloor moisture-control strategy.
