I am about to install my engineered wood floors in my basement and I am wondering if I should be placing anything underneath them?
I have already placed a dimpled moisture barrier on top of the concrete, followed by a 3/4" layer of T&G OSB which has been screwed (the screws were caulked first) down into the concrete.
I am going to staple down the engineered floors because I am not a big fan of the sound from a floating installation, and I do not want the hassle of gluing. So I am wondering if I should be placing some kind felt paper or something under the floors? Does it make it easier to install or reduce squeaking? Or is it just a waste?
The manufacture really doesn’t say anything besides the type of nails/staples and the tolerances.
