Three years ago my neighbours in the flat above me had a leak from their bathroom. I was away and the whole ceiling of my bathroom collapsed. They got the ceiling replastered and I repainted it. I used Dulux Vinyl Matt paint. This may have been a mistake because the paint is now peeling off above the bath. I don't think that this is because of more moisture coming through from above - the plaster seems dry - but rather because of condensation above the bath.
What do I do about this? If I try sanding the existing paint back to prepare it for repainting the edge remains very flaky, and before long it will start peeling again. Does the whole ceiling now need sanding back (groan) and repainting with something more waterproof?
