INSTALLATION INSTRUCTIONS

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.

Floating Installation

  1. Roll out underlayment rubber side up and parallel to the wall, in the opposite direction the floor covering will be installed.
  2. Trim the underlayment to fit the sub-floor, leaving a 1/4” gap at each wall.
  3. Roll out the next section of underlayment in the same manner making sure the seams are butted together but not overlapping, and close the seams using the attacked lip and tape system.
  4. Install the floor covering according to the manufacturer’s guidelines.

Nail-Down Installation

  1. Roll out underlayment rubber side up and parallel to the wall in the opposite direction the floor covering will be installed.
  2. Trim the underlayment to fit the sub-floor leaving a 1/4” gap at each wall.
  3. Roll out the next section of underlayment in the same manner making sure the seams are butted together but not overlapping and close the seams using the attached lip and tape system.
  1. Install the floor covering according to the manufacturer‘s guidelines.
