EZ-Floor Foam Underlayment Instructions Jobsite Conditions

  • 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.
Subfloor Preparation
  • 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.
  • EZ-Floor LVT underlayment must be installed perpendicular to the length of the plank being installed and the moisture barrier must be facing down towards the subfloor.
  • Determine the layout, noting that the seams of the underlay are at least 4” away form the seams of the material being installed.
  • Cut the underlayment to the desired length and position it in the space to be covered.
  • A 1/4” space needs to be maintained between the material and any walls or fixed objects for expansion and contraction.
  • Cut the second sheet of underlay to length and position it with seam butted tightly to the first sheet.
  • Secure the sheets with tape.
  • Proceed to cover the entire room, making sure the sheets are tightly butted together, without gaps.
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.

    What is the STC rating on this underlayment? I am putting luxury vinyl plank on it and it has a STC of 53. The condo board is requesting a 70 STC.


    Our EZ-Floor Foam Underlayment has a STC rating of 66. We do have two other underlayments that have STC ratings above 70. They are our Silent Silver and our Sound Blocker underlays.

    Dry back, glue down vinyl planks can be glued directly to our EZ Floor Underlayment. Interlocking vinyl planks should not be glued.
