Instructions / Details

1. Apply the Acoustic Sealant around the entire perimeter of the room. Seal all cracks and holes.

2. Make sure the sub-floor surface is clean, dry and free of obstructions.

3. Start in a corner. Unroll the Step Above® flooring underlayment over the sub-floor with the vapor barrier film side down. Be sure the tape side is next to the wall and the overlapping lip is toward the open room.

4. Roll out the next row in the same manner. Butt the underlayment close to the first row. Be sure to overlap the vapor barrier lip and not the underlayment material.

5. Remove the tape liner from the bottom of the underlayment and secure it to the vapor barrier lip of the adjoining piece. Seal all open seams with an aggressive adhesive plastic tape.

6. Install the flooring per manufacturers instruction

Note: For increased performance add Quiet Batt® Soundproofing Insulation between the floor joists.
