Premium Felt Underlayment Instructions
- The room, underlayment, flooring materials and adhesives must be maintained at 65 to 85 degrees F and the relative humidity below 60% for 48 hours prior to, during and after the installation.
- All subfloor work should be structurally sound, clean and level. The moisture content of the subfloor should not be more than 10 lbs. Per 1000 s/f 24rs as measured via a Calcium Chloride test, before the underlayment is applied.
- Start in the corner of the room and unroll the underlayment over the subfloor with the vapor barrier film down, touching the subfloor.
- Be sure that the tape strip side is next to the wall and that the overlapping lip is facing towards the middle of the room.
- Roll out your next row in the same fashion, this time butting the felt up against the first row and covering the overlapping moisture barrier lip. Do no overlap the felt itself.
- Remove the tape liner to secure the overlapping moisture barrier to the adjacent roll barrier. Continue in the same manner with the remaining installation.
- When finished, seal all of your open seams with an adhesive plastic tape.
Note: Gaps in the underlayment may “telegraph” through some resilient floors, so the underlayment should be installed as smoothly and as well seamed as possible.
