I guess I know the answer to this is likely to be "it can always be repaired"..... but,
I have a mixture of plasters - the oldest has a wattle and daub background with lime covering (very fine finish with goat hair in the top coat) and the remains of a lovely hand painted design on the wall.
My question is this - I'd like as far as possible to repair most of the plaster but it's in a very poor state (very hollow in places - but still reasonably stable - i.e. most plaster won't move if you press on it). So just how bad does it have to be before it needs to come off and be replaced- i.e. beyond repair?
Image shows picture of one wall of dining room - all plaster in this room was covered by wallpapered hessian pinned on a wood frame. Note small black dots - these are old nails holding plaster to the wall.

Condition of the worst wall.
