When I moved into my house there was a patch in the utility room where the plaster was coming off the wall.
I had a damp course done and in the rest of the house everything was fine, but that particular patch came back - the plaster appeared to dry out normally, and everything was fine for about a year but then it sort of erupted and started breaking off. But only in that patch.
I called the damp proofers back and they pulled the whole of that wall off and redid it.
Now, eight months later, it is happening again! But it isn't damp coming up from the ground or anything, as it is still only that same small patch.
It is a single skinned wall and single storey, but it has had a new roof on and I painted the outside with Dulux Weathershield, then the guys who did the damp proofing gave me some Remesheen Clear to paint over the top.
I can't face having the plastering done again and to be honest it doesn't seem to help. I've seen the wall behind and there are no pipes or anything in it. I don't know what to do, short of knocking the wall down and rebuilding it (which isn't really an option).
Any ideas? Thanks for any help.
