Thank you very much for taking the time to submit this great review on Sydney. All subfloors must be clean, flat, dry and structurally sound. The correct preparation of the subfloor is a major part of a
successful installation. Subfloor must be flat – 3/16" in 10' or 1/8" in 6'. Use cementitious patching and leveling compounds that meet or exceed maximum moisture level and pH requirements. Use of gypsum-based patching and/or leveling compounds which contain Portland or high alumina cement and meet or exceed the compressive strength of 3,000 psi are acceptable. It is recommended that you roll the flooring immediately after installation with a 100 lbs. 3‐section roller. Thank you again for the great review and the wonderful advise to our future readers.
