Hi,
I know there is already loads of posts on this subject but I am still yet to find an answer to my question. Or maybe it's that I want to hear an answer that doesn't exist.
I have done an extension on the side of my house which has standard building regs concrete floor, loads of hardcore, blind, dpm, celotex, dpm,reinforced concrete, and then a sharp sand screed. Over the top of the sharp sand screed I have put sbr to key it and a very thin 2-3 mm layer of fibre flex levelling compound. Now my extension floor is the exact same height as my existing house. I was planning to stick with a flexible adhesive my 18 mm solid oak down to my nice level floor and then as I leave the concrete floor area and continue into the old house I would screw or nail it to the floorboards. The concrete floor has been down for 6 months.
Does anyone think that I need to put another dpm on top of this under the oak?
If so, is there a liquid one I can stick straight to? I really don't want to bring the floor up any more as I got it spot on and I am quite proud of myself!
Any help much appreciated!! My floor arrives tomorrow!!
