EFA Elastomeric Flooring Adhesive is a one-part, trowel-applied, moisture-cure urethane adhesive; this adhesive does NOT contain any water. Once cured, EFA is waterproof and is not adversely affected by exposure to moisture or water. When applied as directed for a moisture vapor membrane, EFA will reduce moderate amounts of moisture vapor transmission from the subfloor and prevent damages to engineered wood flooring caused by subfloor moisture.
EFA Elastomeric Flooring Adhesive may be used to adhere all engineered, solid (adhesive only), bamboo (adhesive only), cork, and parquet (adhesive only) designed and recommended in writing by the hardwood flooring manufacturer for glue-down applications. 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.
Bostik’s EFA is recommended as a moisture membrane beneath dimensionally stable, engineered wood flooring only.
EFA Elastomeric Flooring Adhesive may be used over all properly prepared substrates common to hardwood flooring installations including: concrete, plywood, particle or chipboard (underlayment grade), well-bonded vinyl/VCT and ceramic tile, cement backer board, gypsum underlayments (dry, above-grade), cement patch/underlayments, radiant-heat flooring, and properly prepared terrazzo.
