I have a damp problem which I've been advised is due to salts from a chimney coming through a wall and causing the surface to be hygroscopic so damp air condenses on it. I've had window repairs so hopefully have reduced the level of damp air getting in. The advice I was given was to have all the plaster hacked off and the wall redone with various products to keep the salts at bay.
The cost and disruption has made me look for an alternative. The existing plaster is in good condition, so I wonder if I can scrape off the existing paint and some apply some appropriate material to the plaster. What would work (if anything).
One other issue is that some of the paint has a bluish tinge. It went on grey but it seems that the pigments have separated on the damp areas and blue has risen to the surface. Is this normal?
