Dear all,
I wondered if anyone had some advice about the (presumably original) oil paint that covers some of our interior walls (house built 1924, outside Berlin). Underneath the paint is original lime plaster (throughout the whole house) and we would like to skim over with lime plaster again to make it presentable.
Does the oil paint need to come off because it's not breathable? . By scraping or sanding?
Or is it possible just to plaster over oil paint (using a primer first), for example on the first floor interior walls that are likely to be dry?
The oil paint is visible on the photo as the brown colour with black border. You can also see they've used cement/concrete to patch up the plaster where it's come off at the bottom. Should we try to remove the cement patches or leave them? It's on the ground ground floor and the walls are fairly wet, presumably from rising damp as we have no DPM/DPC.
Where the plaster has broken off around the doorframe I thought of repairing it with a tub of ready-mixed lime mortar (NHL5) I have to hand - does that sound about right?
In other areas of the ground floor the plaster has been 'painted' over with something but it's more chalky in appearance [see the other photo, the closeup]. It needs to come off to improve breathability, or just skim over it? Use primer first?
Thanks a million
