Underpads are thin layers of foam or rubber that go under your floors to provide cushioning, sound absorption, and insulation. They are especially useful for laminate and vinyl floors, which can be hard and noisy without them. Installing an underpad is not hard, but it does require some preparation and attention to detail. Here are five simple steps to follow:
Step 1: Remove Old Flooring and Underpad
Before you can install new underpad, you need to remove any existing flooring and underpad from your subfloor. This may involve pulling up carpet, tiles, planks, or sheets of flooring material. You will also need to remove any nails, staples, glue, or debris that may be left behind. Use a pry bar, hammer, utility knife, and pliers as needed. Be careful not to damage the subfloor as you work.
Step 2: Prepare Your Subfloor
Once you have a clean and smooth subfloor, you need to make sure it is level and dry. Use a long level or a straight edge to check for any dips or bumps in the subfloor. If you find any, you can use a self-leveling compound or shims to even them out. You also need to measure the moisture level of the subfloor using a moisture meter. If it is too high, you may need to install a vapor barrier or wait for it to dry before proceeding.
Step 3: Unroll the Underpad
Next, you need to unroll the underpad and lay it over the subfloor. Underpad usually comes in rolls of 6 feet wide, so you may need more than one piece to cover the entire floor area. Start from one wall and unroll the underpad parallel to the direction of your flooring planks. Leave a gap of about half an inch between the underpad and the wall. Do not overlap the underpad pieces; instead, join them together at the edges.
Step 4: Tape or Staple the Underpad
To secure the underpad in place, you can either use tape or staples depending on your subfloor material. If you have a wood subfloor, you can use a staple gun to staple the underpad around the perimeter and along the seams every 8 inches. Make sure the staples are flush with the underpad surface and do not stick out. If you have a concrete subfloor, you can use duct tape or special underpad tape to tape the underpad around the perimeter and along the seams.
Step 5: Trim the Excess Underpad
Finally, you need to trim any excess underpad that extends beyond the floor area. Use a utility knife and a straight edge to cut along the edge of the wall or baseboard. Be careful not to cut into the subfloor or the wall. Dispose of the excess underpad properly.
Congratulations! You have successfully installed an underpad in your room. Now you are ready to install your flooring planks on top of them. Enjoy your new floors!
