Roberts understands installing a new flooring can be challenging. Here are some key product usage and product info points to help projects flow a bit smoother. 1407 acrylic wood flooring adhesive is also available in 30oz cartridge size which may help install tight spots. The 1407 is specifically designed for use with engineered wood floor up to 5" wide and 1/2" thick. Always prepare the subfloor to be structurally sound, dry, flat (≤ 3/16" within 10') and free of excess moisture/alkali and all substances (oil, debris, dust, paint, oil based sealers, adhesive residue, etc.) that may inhibit the bond of the adhesive or the performance of the flooring after installation. Ensure 100% transfer of the adhesive occurs to the back of the wood planks. Observe the appropriate amount of open time prudent to the installation conditions and trowel size (minimum size trowel= 1/8"). Always follow the floor manufacturer's specific installation guidelines. - Customer Care
