THICKNESS CONTROL™ SPACER TECHNOLOGY
Vapor-Lock™ contains Bostik’s patent-pending Thickness Control™ Spacer Technology. This proprietary feature helps ensure proper membrane thickness is maintained between the hardwood flooring and substrate. Installers can use rubber mallets to engage the tongue and groove or even walk on their work during the installation process without significant reduction in the film thickness that could compromise moisture protection and sound control.
ULTIMATE VERSATILITY
VaporLock™'s high performance formulation may be used to adhere engineered, solid, bamboo, cork, and parquet hardwood, and cork or rubber underlayments. Vapor-Lock™ has no restrictions on board width or length. It may be used over all properly prepared substrates common to hardwood flooring installations including; concrete, plywood, OSB, well bonded vinyl/VCT and ceramic tile, cement backer board, gypsum underlayments (dry, above grade), cement patch/underlayments, radiant-heat flooring, properly prepared terrazzo, and recycled rubber underlayments. This adhesive can also be used to install plywood as described, as well as ceramic tile, marble, and stone inlays for light commercial and/or residential applications.
MOISTURE PROTECTION
Vapor-Lock™ has very low moisture vapor permeability and is not adversely affected by moisture vapor. As a result, it will reduce moisture vapor transmission through the concrete. When applied as directed as a moisture vapor membrane, it will prevent damages caused by high subfloor moisture vapor. As a result, costly and time-consuming concrete moisture testing is not required for solid or engineered hardwood flooring when the slab is properly prepared, dry to the touch, and fully cured. For bamboo flooring, Vapor-Lock™ may be used for concrete slabs with elevated moisture levels up to 15 lbs. per 1,000 square feet per 24 hours (using an anhydrous calcium chloride test kit according to ASTM F-1869 test method), and up to 87% RH (tested in accordance with ASTM F-2170). For bamboo flooring on substrates that have an MVER of greater than 15 lbs or 87% RH, use Bostik MVP4® prior to the application of Vapor-Lock™, or use Bostik Ultra-Set® SingleStep2™ or GreenForce® for unlimited moisture vapor protection.
