Vapor-LockTM is a one-part, trowel-applied, rapid tacking, low permeability, moisture-cure, urethane adhesive and vapor retarding membrane. This scientifically formulated adhesive/membrane does NOT contain any water, is virtually odorless, and has zero VOC’s per SCAQMD 1168. 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″). Vapor-Lock contains Bostik’s patent pending Thickness ControlTM Spacer Technology to ensure proper membrane thickness between hardwood flooring and the substrate.
Vapor-Lock may be used to adhere all engineered, parquet, solid and bamboo flooring that is designed and recommended in writing by the hardwood flooring manufacturer for glue-down applications.
This product 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.
Vapor-Lock’s zero VOC formulation contains 1% recycled rubber material and therefore may contribute to the qualification of a project for LEED NC V3 certification under the following Indoor Environmental Quality credits for low emitting materials; EQ 4.1 Adhesives & Sealants, as well as USGBC LEED credits MR 4.1 & 4.2 for recycled content.
Vapor-Lock may be used over all properly prepared substrates common to hardwood flooring installations, Including: concrete, plywood, particle or chip board (underlayment grade), well bonded vinyl/VCT and ceramic tile, cement backer board, gypsum underlayments (dry, above grade), cement patch/underlayments, radiant heat flooring, and properly prepared terrazzo and ceramic tile.
