Actual coverage will vary depending on the substrate and application. For estimation purposes, a 1/8” x 1/8” x 1/8” square notched trowel will yield 90 sq.ft./US-gallon. 
* Trowel size is suggested to maximize coverage of adhesive. 100% coverage is required for all flooring. An uneven subfloor may require a leveling/patching material or a larger notched trowel for proper coverage of adhesive
