But Before You Begin…

One of the easiest ways to ensure you have a successful project is to prepare before you begin. With all of the necessary supplies, tools, and materials on hand your project can complete your project in a fraction of the time.

Supply List:

  • Enough Vapor 3-in-1 Silver Underlayment
  • Flooring
  • Broom or a Shop Vacuum
  • Tape
  • Utility Knife

Step 1: Clean Away All Debris From the Subfloor

Before you lay the first section of underlayment, you need to clear away all debris, dirt and objects from the subfloor. Using a shop vacuum is best. If you don’t have a shop vacuum available, you can also use a broom. Give your floors a good cleaning. This will ensure that your project is a success!

Step 2: Do a Sub-Floor Double Check

Damage to your subfloor might be subtle but it can have a tremendous impact on your project’s success. Look over every detail of your subfloor to make sure that there is no damage. If you notice any cracks, holes, protruding objects, or sections that are not level, stop. You’ll need to repair these damages before you can continue.

Step 3: Time to Begin!

Once the subfloor is clean and well-inspected, you’re ready to begin. Get started by rolling out the underlayment with the silver side facing down. The tape strip should be flush up against the wall. Leave the overlapping section on the side that goes out toward the room. You’ll need this section later as you continue to unroll your underlayment.

Step 4: Do a Side Check

Double check that the flooring you just unrolled is facing the correct sides. The tape strip should be next to the wall, and the overlapping film must open toward the room. If this is backwards, it is important to fix it now or your floor will not be installed correctly.

Step 5: Install Parallel to the Wall

Make sure your underlayment is installed parallel to the wall. This is the best way to ensure your underlayment works the way it should.

Step 6: Cut and Paste

Once you’re sure that your underlayment is facing the right direction and is parallel with the wall, you can cut it. Cut the underlayment using a utility knife for the most exact results.

Step 7: Add Temporary Tape

At this point, you might want to add tape to the underlayment to keep it in place temporarily. This helps prevent the underlayment from shifting while you work.

Step 8: Add your flooring

With the first row of underlayment down, it’s time to install a small section of your flooring. Follow the directions from the manufacturer to make sure you install your flooring on top of the underlayment correctly.

Butt the edges of the underlayment together. Make sure that you only overlap the silver film.

Step 12: Tape if Needed

If the underlayment does not seem to be secure, you might need to add extra tape. Put this tape over the seam to avoid the two layers from slipping away from each other.

    Hi Rod, thanks for the question. I would trim so you still have tape, or you will just need to use tape of some sort instead. It won’t matter as far as the underlayment usage which you cut.

    When I am laying the underpayment and my next row is narrower than the roll it comes in. Do I trim the side away with the sliver side or do I trim so I still have the tape side?

    Hi Brian, thanks for the question. I believe they state this to make sure seams are not lining up (underlayment seam with floor seam), meaning there is no opportunity for there to be gaps between the underlayment and floor locking system. I do not believe it will make a difference, however, if you do install the other direction.

    The underlayment manufacturer states to roll out the underlayment PERPENDICULAR to the way I’m going to lay the flooring. Never heard of this. Is there a reason ? Does it really matter ?

    This was very helpful. There are no clear instructions on the package the underlayment comes in. Easy to install much easier after looking at these steps.
