DPM & underlay for oak floor

[deanmacken]

Hello All, just about to lay solid 20mm oak t&g floor. part of the floor is concrete (modern with a dpm) which i will be battening. i understand i should use a DPM on top of the concrete before battening. should i just use the usual black polythene or is there another product i should be using?

another part of the floor is non t&G old pine floor, should i be worried about damp coming up through the joins and if so should i use a dpm here?

TIA

Dean

Is no-one interested? sorry if this has been answered before.

no dpm over the wood section and you are o.k to use normal plastic sheet over the concrete section.
