Painting lime render

GreatOaktree

Hi all,
Myself and my girlfriend have bought a stone house. It is over 100 years old and was renovated sometime before we bought it. The first time we visited it at night time there was a film of water vapour over the kitchen walls which were finished in gloss paint.
Now from what I understand stone buildings are rendered in lime for permeable reasons. So we decided to strip the gloss paint (which was not allowing moisture to escape) only to find that in some areas somebody has applied that pink skim ( forgive my terminology ) making scraping the paint next to impossible and in places the skim has come off with the paint leaving a very dusty lime surface.

My questions are as follows :
1) Is the pink skim permeable ?? should I remove it all ??
2) How do I finish the dusty areas in order to make the paint take to it ?? (in some areas the lime render seems polished).
3) what paint type should I apply? or is there permeable paint ?

There are a couple of different types of breathable paint that you can use. Farrow and ball or zinsser for example. If the new plaster is sound then I"d leave it. If it looks like it wants to come away then remove it. Dust down before applying paint. Your local paint shop should provide you with info you need, stillorgan decor is very good if you are in Dublin.

Thanks for the reply. I did exactly that but bought a primer/sealer and ordinary paint. It's coming along nicely. I know I should have bought the breathable stuff and will for the rest of the house.
Thanks again.
