Bostik's TKO® is a one-part, trowel applied, moisture-cure urethane adhesive; this advanced scientifically formulated adhesive does NOT contain any water. Once cured, Bostik’s TKO 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. Bostik’s TKO elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor. When applied as directed for moisture vapor membrane, Bostik’s TKO will reduce moderate amounts of moisture vapor transmission from the subfloor and prevent damages to engineered wood flooring caused by subfloor moisture.Information provided by Bostik |
