Why you shouldn’t just paint over damp walls.
Damp patches can cause paint or plaster to flake or peel off, or leave a white salt residue, making it look very unappealing. However, painting over it will not make the issue go away.
Painting the damp wall will just temporarily hide the signs of the damp and water ingress, not deal with the source of the moisture issue.
The source of the moisture needs to be professionally investigated and identified, and fixed. This ensures the paint doesn’t peel anymore or identifies any other more serious issues because of the prolonged water ingress.
If you see visible damp patches, it is best to get it checked out and remediated at the earliest opportunity.
