Hello
I had a damp patch on the ceiling in my daughter's bedroom. The damage is now repaired and it is dry but when painted with matt white, the yellow stain quickly shows through. My Dad was told by a plumber that you can paint gloss over stains first and then matt and that will stop it coming through. Any thoughts on this? I am reluctant to do it in case the matt will not then take.
Thanks
