We live in a 300yr cottage, I think we are getting condensation on the wall as its damp. I've knocked it back to the wall (the hole in picture) it's got a gypsum skim on it, then this white stuff, guessing lime plaster. Then a sandy coloured material underneath.
What are these materials and do they breathe as read old houses need to breathe? If not what should I do to sort it?
Kind regards
James
