How Do I Install Underlayment?
The process of installing underlayment for a new floor project begins with one crucial action: you must clean the subfloor, or existing flooring, thoroughly.
Make sure every bit of dust, dirt, and other debris are removed and that the surface has been washed and is completely dry.
From there, the installation of an underlayment is fairly easy.
Lay the underlayment in the opposite direction of the flooring.
Simply roll the material out beginning in a corner, shiny side up to the other side of the room.
Make sure to leave 2" around the edges on all sides (this will be trimmed off after the flooring is installed.
Subsequent pieces butt up next to the previous piece but never overlap.
Seal the seams using clear packing tape the entire length of the seam.
Generally, you won't need to worry about attaching the underlayment to the floor. However, at certain spots, it might be a good idea to glue the underlayment to the subfloor to provide added stability such as frequently used doorways and rooms that get a lot of bright, natural sunlight.
