70-025 Qep Unison Underlayment

The width of a row of Roberts Unison™ Underlayment is comprised of 48 inches of underlayment plus a 3-inch overlap flap.
The overlap flap with a peel-and-stick strip connects each row of underlayment and protects the new floor from any moisture that could be carried up through open seams.

Installation Steps

  1. Always follow the flooring manufacturers’ installation instructions with respect to preparing and leveling the sub-floor. Make sure the subfloor is level, clean and dry.
  2. The 3 inch overlap flap is not used for the first row of underlayment installed. Trim off the overlap flap prior to installing the first row. This material should be used later to properly seal adjoining rolls of underlayment and to repair cuts or tears that may occur during installation.
  3. Start in the corner of the room by rolling out the underlayment with the logo side facing up. Run the underlayment 2 inches up both the starting end wall and the side wall (See Fig. A). This 2 inch perimeter running up the wall provides a moisture-proof enclosure for the flooring.ROBERTS 70-025 Qep Unison Underlayment - Fig 1
  4. Lay a second row of underlayment alongside the first, with the overlap flap facing the first row. Allow for the ends to wrap up the end wall to maintain the 2 inch perimeter of underlayment around the room.
  5. Fold back the overlap fiap to expose the peel and stick strip. Remove the protective cover from the adhesive strip (See Fig. B), and lay the overlap flap across the first row of underlayment. Press into place (See Fig. C). Repeat Steps 4 and 5, row by row until the entire floor area is covered.ROBERTS 70-025 Qep Unison Underlayment - Fig 2ROBERTS 70-025 Qep Unison Underlayment - Fig 3
  6. After the flooring is installed, trim the excess underlayment back to the height of the finished floor. Do this prior to installing base or molding (Gee Fig. D).ROBERTS 70-025 Qep Unison Underlayment - Fig 4
