Great for laminate and engineered hardwoods, Vapor Barrier 2-in-1 Underlayment provides the cushion of underlayment with an additional vapor barrier to protect your floors from any moisture that may come from the subfloor. This can be recommended for either wood or concrete subfloors. If you are installing flooring with an underlayment pad attached, use the Visqueen Film Vapor Barrier instead.
Before starting the installation, be sure you have all necessary tools and supplies ready. Read the manufacturer instructions before beginning and understand the process. Good organization will save your time and energy!

Step 1: Properly Prepared Subfloor
Have you leveled, repaired and cleaned your subfloor? The subfloor must be free of dirt and debris. Get specific instructions for preparing wood and concrete subfloors.
Step 2: Roll the First Row
Begin by placing the roll on the ground with the film side down, facing the subfloor. Measure the length of the room and cut a piece accordingly. Due to the size of the roll, you will not be able to roll it to the wall and get an accurate measurement.
Step 3: Direction
This specific underlayment comes with an overlap of film. This overlap should be positioned towards the open room and the foam will face the wall. Lay the underlayment out in the first row following this direction.
Step 4: Begin Your First Row of Flooring
Follow the manufacturer’s directions and begin your first row of flooring. Depending on the flooring width, you will be able to install a few rows. When you reach 1 foot away from the underlayment, stop the installation and roll out a second row of underlayment.
Step 5: Second Row of Underlayment
Begin unrolling or pre-cutting (Step 2) the underlayment and place the foam side over top of the the film overlap from the previous row. Butt the edges together, creating a nice seam, but not overlapping.
Step 6: Tape the Seams
Using any industrial tape, adhere the seams together to create a flat, even surface.
Step 7: Continue the Flooring Installation
Continue installing the flooring, following the previous steps. The flooring and underlayment should be installed in sections.
