Which wood flooring underlay and do I need to level floor?

[monkeymagic]

Hi,
Please can anyone tell me what underlay I need to buy to fit a solid wood floor? and do I only need to fit underlay or another barrier?

Also will this underlay take out the uneveness in the floor? The floor is not level in some places.

hi, you only need underlay for the floating method.
We also need some more info-
How uneven is the subfloor?
What is the sub floor? (wood or concrete)?

Hi,
The sub floor is concrete

I don't know how to describe how uneven the sub floor is really - even in some places and some places a few mm uneven - at a guess 5 - 7mm deviation at worst parts.

You need to remove any dips with levelling compound before you attempt to fit. Then any underlay you wish with a moister barrier if laying floating method.
