Hello
I have an old house in the UK which I am renovating. The walls are stone and on the inside have been lime plastered then had a gypsm skim coat on top. When peeling back the wall paper some of the Gypsm has come off which I am almost certain is due to the moisture from not letting the walls breathe.
My question is can I just remove the Gypsm and then skim a light coat of lime plaster over to get a finish? and if so how will I prepare the lime walls under the gypsm (do I need to wet them down, pva etc?) Also what is the best mix and type of lime needed to apply this top coat.
Thank you in advance.
