Basic Installation Instruction:

  1. Before you start the installation process, be sure to check for protruding nails and defects in the subfloor along with any dust or debris.
  2. Scuba thermo underlayment must be installed with the barrier (i.e., vapor or silver thermo foil barrier) facedown on subflooring. If underlayment has a barrier on either side then the silver thermo foil barrier will be faced up and the other barrier (i.e. vapor barrier) will be facedown.
  3. Install one roll of Scuba Thermo underlayment parallel to the wall and in the opposite direction you plan to install the flooring planks to reduce seams. Next, you will need to cut the underlayment with a utility knife leaving at least 2” going up the wall. Now you should install the planks but while doing this, please be sure that you are able to see the edges of the underlayment so that you can accurately line up the next roll. (Install the surface flooring according to the flooring manufacturer’s written installation instructions.)
  4. Now by butting the seams together tightly, install the next roll of Scuba Thermo underlayment. Do not allow peaking or overlapping of seams. Scuba Thermo underlayment comes standard with an overlap and tape. Make sure there are no penetrations through underlayment. If any, seal all tears or penetrations using duct tape or other utility grade polycoated cloth backed tape with an aggressive adhesive.
  5. As in step 3, please continue to install the underlayment and planks in the remainder of the room. The final 2” of the underlayment that you left on the wall will be covered by the trim or moldings.

The crew worked hard, arrived on time and committed to our project until it was finished! I would highly recommend Ellegant Home Design to redo your hardwood floors, painting and/or both!

I used ElleGant for a kitchen remodel project. The ordering process was simple and I was always told exactly where and when my material would arrive. I also used them for the installation.
