Floor Prep
Sub-floor must be level, clean and dry with no protruding nails or staples. Concrete sub-floor moisture emission rate may not exceed 3 lbs. / 1,000 sq. ft. / 24 hrs in accordance with ASTM F1869. If moisture emissions exceed this level an additional moisture barrier may be required.
ACCLIMATE UNDERLAYMENT FOR A MINIMUM OF 24 HRS. PRIOR TO INSTALLATION.

- Install the floor covering according to the manufacturer’s guidelines.
