Installing Engineered Flooring on a Concrete Slab
When gluing prefinished engineered flooring to concrete, detailing the prep and ensuring a careful layout are key
Part of FHB‘s Master Craftsman series, this article is a detailed look at the process of gluing engineered flooring to a slab. Installer Kevin Ward begins with a thorough look at the preparation of the slab, which must be flat, clean, and smooth. Using a 10-ft. straightedge, he checks the floor for high and low spots, marks them, and either fills them with a patching compound or grinds them down. After sweeping the floor, he next applies a sealer to the concrete. To install the flooring, Ward snaps a chalkline as a guide, then applies the urethane glue with a notched trowel. Working in increments of three to four board widths, he spreads the glue, then puts the flooring down along the chalkline. Buckets filled with sand are used to weight the flooring down in place until the glue dries. The article also features techniques used for scribing flooring into doorways and walls.
