Rated 1 out of 5 by from Worst underlay ever This underlay doesn't even deserve a single star but that's not possible. It's the worst underlay i've ever used and wouldn't recommend it to anyone.

Vapour barrier ?

Does this need a sheet of vapour barrier over a concrete subfloor? Or is it better to get the aquastop version with the silver coating? I.E. Does it absorb or repel moisture? Thank you

Sheet vinyl

Can this be used to even out floorboards before getting vinyl sheet installed?
