Vapor 3-in-1 Silver Underlayment Installation

This is a great product for a multiple array of benefits. Sound reduction, vapor barrier and insulation are all perks of this underlayment. Use this underlayment with laminate, vinyl and engineered wood over both concrete and wood subfloors.

Gather all of your tools and supplies needed for both the underlayment.

• Vapor 3-in-1 Underlayment
• Broom or ShopVac
• Tape (packaging tape works fine)
• Utility Knife/Scissors

Step 1: Do a Sub-Floor Double Check

To start any installation, you need to have repaired, inspected and cleaned the subfloor. Double check if you completed this list for wood or concrete subfloors before you begin!

Step 2: Time to Begin!

Position the underlayment roll with the silver side down, facing the subfloor. The overlapping side should be towards the open room, and the tape strip should be next to the wall.

Step 3: Install Parallel to the Wall

The underlayment will be positioned parallel to the wall and installed the same direction of your flooring.

Step 4: Add Temporary Tape

Cut the underlayment so it lays flat next to the end wall. To help hold the underlayment down, you can use some tape to prevent it from shifting.

Step 5: Add your Flooring

After installing the first row of underlayment, you can begin to install your first row of flooring (this is why you may want to temporarily tape the underlayment in place). Following the manufacturer’s installation instructions, begin to lay the first row of flooring. Once your flooring is about a foot away from the edge of the underlayment, it’s time to add another row of Silver 3-in-1.

Step 6: Start a New Row of Underlayment

Roll out the second roll, measure and cut. Line up the second row, overlapping the silver film from the previous row. Remove any temporary tape you had down.

Step 10: Placing the Edges

The seams should be close together, but not overlapping.

Step 11: Remove the Adhesive

Lift the second row and begin to remove the adhesive. Use the tape to adhere the seams, once again, double checking that the underlayment isn’t overlapping.

Step 12: Tape if Needed

If the adhesive doesn’t seem to be secure, you may tape over the seams to ensure a tight barrier.

Step 13: Finish the Installation
