Underlayment on top of new floor?
As you may have read in other posts, I am almost done with the shell off floor replacement. I am not sure what type of floor covering we will choose yet, but regardless of covering type, should I install Lewan underlayment over the new floor?
Part of me thinks it would be nice to have a seperate layer for glue etc... rather than glueing directly to the new floor. The other part of me wonders if its too much weight and that I don't even need to worry about it.
