How do you do underlayment nails?
Simply so, do you nail down underlayment?
Staple or Nail Down Installation With a staple down or nail down installation over a wood subfloor using solid flooring or engineered flooring, it is recommended that an underlayment of 15lb. black felt paper is rolled out over the wood subfloor prior to installing the new floor.
One may also ask, which side of underlayment goes down? Get started by rolling out the underlayment with the silver side facing down. The tape strip should be flush up against the wall. Leave the overlapping section on the side that goes out toward the room. You'll need this section later as you continue to unroll your underlayment.
Herein, what nails do you use for subfloor?
Nails for Subfloor Realtor.com recommends an 8d nail, which is roughly 2½ inches, to pass through the plywood and bury nearly 2 inches of the nail in the joists below.
What happens if you don't use underlayment under laminate flooring?
Pay close attention to the back of your laminate flooring. If you have purchased a laminate flooring that has underlayment already attached, then you should not use extra underlayment. Having too much cushion can destroy the integrity of the locking system and cause the floor to become unstable.
