I agree with you Joe-90, breathability has probably been lost, i was thinking more for the alkaline properties of the lime inhibiting mould growth.
So, should I start scraping the paint off or do I have any other options?
We have a Victorian terrace with mostly the original lime plaster intact but the walls could now do with skimming. I'm keen to use lime as the walls are solid and where they've been patched up in the past with gypsum plaster, there is occasional mould growth. :(
Is is possible to add a lime...
