Vapor-Lock™ Wood Flooring Urethane Adhesive/Vapor-Retarding Membrane
Vapor-Lock™ is a new and improved one-part, trowel-applied, rapid tacking, very low permeability moisture-cure urethane adhesive and vapor retarding membrane. This scientifically formulated adhesive/membrane does NOT contain water, is virtually odorless, and has 0%-VOC's.

Vapor-Lock offers a tenacious waterproof bond to a variety or substrates and is not adversely affected by exposure to moisture, water, or alkalinity; it can also create a vapor-retarding membrane designed to reduce moderate amounts of moisture vapor transmission from the subfloor and bridge cracks that can occur in the substrate prior to or after installation (up to 1/8”).
