Laying solid wood floor on concrete sub-base

Hi everyone. I’m after some advice please, which I’ll try and keep brief. I plan on laying real wood flooring in my lounge and having taken up the old carpet and underlay to reveal a concrete sub-base. It looks like there is a thin layer of what I assume is bitumen.

Should I glue the wood floor blocks directly to the concrete, or should I put down some form of underlay (and then glue to that)? And can you glue directly on top of bitumen? Finally, what glue/adhesive should I use?? Thanks.

 

Solid wood has to be fully bonded. You will need to take moisture readings of that concrete floor as bitumen is usually a sign that your slab has no dpm and the bitumen has been used as a surface dpm. How old is the house?

Hi Merit. I think it was built in the 1950’s.

 

Then The subfloor won’t have a damp proof membrane

what is the name of the wood you have purchased ?

 

Hi Dazlight. The flooring is called Skanor narrow solid oak. What would you advise I do? Thanks!

 

First thing to do which is really really important when preparing to install Skanor solid wood...now listen (read) very carefully... take it back to B&Q

 

Brilliant...sorry but this is actually great advise

Thanks for the advice. Can you explain why?

 

As dan said your floor will need a liquid dpm and smoothing compound doing before you glue it down.
