This company introduces Bostik EFA, Engineered Flooring Adhesive, a high-quality, engineered flooring urethane adhesive. Through the use of all-new polymer technology, EFA is the first engineered flooring urethane adhesive that performs like a urethane, yet is priced like a latex. The product is a single-component, moisture-cure urethane specifically designed for engineered wood and parquet floor installations. It is specially formulated for high bond strength and flexibility, but when taken up, tears away much easier than other urethane adhesives, according to the manufacturer.
