Durabond® D-332™ Premium Wood Flooring Urethane Adhesive is a one-part, trowel applied, tacking, moisture-cure urethane adhesive; this advanced scientifically formulated adhesive does NOT contain any water. Once cured, D-332 is waterproof and is not adversely affected by exposure to moisture or water; its superior properties provide a tough, flexible, tenacious bond to a variety of surfaces. D-332's elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor.

Durabond® D-321™ Moisture Cure Urethane Adhesive Wood Flooring Adhesive is a one-part, trowel applied, scientifically formulated adhesive that does NOT contain any water. Once cured, D-321 is waterproof and is not adversely affected by exposure to moisture, water, or alkalinity. D-321’s elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor. D-321 is easier to spread, holds a better ridge, and cleans up faster when still wet, than most moisture cure urethane wood flooring adhesives.

Durabond® D-317™ Engineered Wood Flooring Adhesive is a one-part, trowel applied, moisture-cure urethane adhesive; this advanced scientifically formulated adhesive does NOT contain any water. Once cured, D-317 is waterproof and is not adversely affected by exposure to moisture or water; its superior properties provide a tough, flexible, tenacious bond to a variety of surfaces. D-317’s elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor.

D-288 Moisture Vapor Protection is a one-part, trowel applied, elastomeric, moisture cure urethane membrane designed to reduce moisture vapor transmission from the subfloor; create a noise reduction barrier over the substrate; establish an anti-fracture membrane that can bridge cracks that can occur in the substrate prior to or after installation (up to 1/8”); prior to the installation of engineered and solid hardwood flooring with D-332 and D-317 adhesives. D-288 may be used over all substrates common to hardwood flooring installations including: concrete, plywood, particle or chip board (underlayment grade), well bonded vinyl, ceramic tile, cement backer board, cement patch/underlayments, radiant heat flooring, and terrazzo.D-288 contains Bostik’s BLOCKADE™ 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.

Bostik’s EFA Engineered Flooring Adhesive is a high-quality, single component, moisture cure urethane adhesive designed for dimensionally stable wood flooring such as engineered wood and 5/16” parquet floor installations. It is specially formulated for high bond strength and flexibility, but when taken up with a pry bar, tears away much easier than any other urethane; a feature that greatly reduces labor charges. EFA contains no water or chlorinated solvents, and will not cup or end lift even the most sensitive hardwood flooring products.

MVP4® Moisture Vapor Protection is a one-part, trowel applied, elastomeric, moisture cure urethane membrane designed to 1reduce moisture vapor transmission from the subfloor; 2create a noise reduction barrier over the substrate; 3establish an anti-fracture membrane that can bridge cracks that can occur in the substrate prior to or after installation (up to 1/8"); prior to the installation of engineered and solid hardwood flooring with Bostik’s Best®, BST®, EFA®, Ultra-Set® Hardwood or Fast Tack® adhesives.
