Plaster has cracked and lifted in places - having taken some plaster off, the concrete behind has also come away and there is a strong smell of damp - not good!
So, I thought either:
- take off all of the plaster and concrete, re-screed and plaster again
- as above but instead of re-screeding and plastering, PVA and leave bare bricks showing
- as 1, but plasterboard then paint
- something I've not yet thought of hence the post!!
Suggestions gratefully accepted from the fountain of knowledge as I am not a builder by trade...
