A one-component wood flooring adhesive formulated with advanced MS Polymer technology. It 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. It also reduces moisture vapor transmission from the subfloor, help protecting the wood floors from warping. Its elastic characteristic allows the wood floor to expand and contract without cracking, and deaden floor sound induced by foot traffic. The non-slump formula enables notched trowel ridges hold firm, bridging gaps between wood flooring and sub floor and reduces floor hollowness problem. Since there is no water or solvent present in the content, it will not cause dimensional changes to wood floor. It is also human and environmentally safe.
