Bostik Vapor-Lock

Product Overview

Vapor-Lock™ is a one-part, trowel-applied, rapid tacking, low permeability, moisture-cure, urethane adhesive and vapor retarding membrane. When applied as designed and cured, Vapor-Lock offers a tenacious waterproof bond to a variety of 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″).
