Baseboard Heater & Laminate Floor Underlayment Installation

Choose the longest wall of the room and unroll the padding along its entire length. When you read the end of the expanse, cut the underlayment padding free from its roll so you have a long section laid out. Repeat the process with the next row of padding, running it along the first row. Do this until you have the entire surface of your installation area prepped with lengths of padding.

Install the padding based upon the installation instructions of the manufacturer. For example, if you are working with padding that is to be installed on top of concrete, you will be using a lip-based padding that has adhesive applied to the underside of the padding. Once the protective barrier is pulled away, the padding adheres to the concrete. For wood floors, you can staple the padding in place with a hammer tacker.

Dry cut the area underneath the baseboard heater before you adhere or tack the padding down, if necessary. Check first. Slide the underlayment padding under the baseboard heater. If it slides under without any issues, you do not need to cut the padding. If the baseboard heater is too low to the floor, cut the padding out around the baseboard with the utility knife before installing.
