At some point I’m going to paint or shellac then paint this ceiling. I’ve covered the cause of the peeling in another question so please don’t worry about that - it’s because of humidity due to not using the extractor fan.
Until I do the repair, would there be any problem if removed all the current paint then covered the ceiling with foil paper and taped it up with painters masking tape to temporarily hold the plaster smell in?
Or might this damage the ceiling in any way so it’s best not to? I don’t really shower there at the moment so condensation isn’t a problem plus extractor fan is on.
