How come laminate can be layed on the floor completely floating, but engineered wood needs to be nailed down, even when both use a locking system?
Not really, depend where is the damp from?I just discovered a damp patch in the middle of the concrete subfloor. I presume I can put down a black polythene DPM before the usual fibre underlay?
How is that better than polythene? Isn't it just and impermeable skin either way?I would seriously consider a liquid DPM then
might not be if you have serious amounts of water coming up, but if it is just a bit of vapour it will stop it actually getting to the surface and condensing, with polythene overlay if it actually gets to the surface it could just run on top of the slab under the polythene not necessarily a total problem but could for example wet the bottom of your plastered walls cause mold etcHow is that better than polythene? Isn't it just and impermeable skin either way?
