Dry Lining an interior flint wall

Postby Elizabeth Holland » Wed Aug 03, 2011 2:10 pm

I need to dry line an interior flint wall that already has lime mortar on it. Am I right in thinking that I build the frame, then cover it with polythene, then breathable DPM and finally plasterboard? It's the polythene and DPM stages I'm unsure about. Advice gratefully received!

Hi Elizabeth,

The wall needs to breath so it would be the DPM first or coat the wall with a breatherable sealer.

You can then insulate then use the polythene or foiled backed plasterboard.
