A user-friendly wood flooring adhesive formulated with advanced MS Polymer technology. It cure on exposure to atmospheric moisture, develops superior early strength for immediate grab, and quickly forms a tenacious but elastic bonding for wood flooring and wall decorative materials. When cured, it is waterproof and is not adversely affected by exposure to moisture or water. When the adhesive is applied as a moisture vapor membrane with the proper trowel, it will reduce moderate amounts of moisture vapor transmission from the subfloor, thus protecting the wood floor from warping. Its elastic characteristic allows the wood floor to expand and contract without cracking, and deaden floor sound induced by foot traffic.
