Floorensics Inc. provides a complete line of concrete slab preparation services for the installation of hard surface flooring.
Flooring should always be protected from substrate moisture!
From the National Wood Flooring Association:
“Installation constitutes acceptance of flooring material, subfloor/substrate, the jobsite itself including the ambient temperature and relative humidity at the time of installation, and all impacting variables that may affect a wood floor.”
“For glue-down installations and installations using mechanical fasteners of less than 1-1/2”, the subfloor should be flat to within 3/16” in 10 feet or 1/8” in 6 feet.”
“Concrete slabs must meet a moisture specification when tested in accordance with the prescribed procedures, at the time of installation of the flooring, and also at any future date. The moisture specification shall be that the emission of moisture vapor from the floor shall not exceed 3 pounds per 1,000 square feet per 24 hours.”
