Any plasterers or builders? Help needed please!

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.

Was your home built on a red Indian burial ground?

Or maybe get a builder/damp proof specialist in to have a look?

Condensation?

It's a cold, single skin wall. It need insulating on the inside. At present it sound like the humidity in the building is condensing on this wall as the poster above suggests.

A cheap solution. Batten out the wall inside and insulate the space, then cover with plasterboard and decorate.

If it was condensation, wouldn't there be some sign, like moisture on the wall? Wouldn't the whole wall be affected?

I am not ruling out the burial ground.

could you not dot & dab plaster board on first then skim over this that was the plaster should be less likely to pop & crack and the dot & dab provides a small gap between the outside wall & your new plaster.

Has it been damp meter tested? If it's not showing as damp it could well be condensation.

Yes. When they came and redid it they tested it and said it wasn't damp but they redid anyway as they said something about damage from salts.
I suppose I just thought if it had been condensation they would have said so then, as redoing the wall was never really going to help :(

Battening out will provide the gap it sounds like you need to stop the effervescence of the salt coming through.

They have tested it and it's not damp, so there's no panic.

Thank you very much for your help.
Just so I'm clear - do the battens and plasterboard go on top of this erupting plaster, or does this bad plaster need to come off and then the battens and plasterboard go on? (I will be getting a builder to do it, but I would like to know what I am asking them to do!).

Hacking the plaster off will stop the salts (the salts are actually in the plaster! Then batten the area with 1" x 1" battens (should be adequate) then insulate the area (there is a polystyrene type you can use), then secure foil backed plasterboard over, then decorate as necessary. It's basically to 'warm' the wall up. You may be OK with standard plasterboard. I have done the same job for a mate 2 years ago and he has had no issues since.

Thank you so much. You wouldn't believe how much stress this has been causing me!

Thank you also to Jimston.

You can also get polystyrene backed plasterboard to aid with insulation.
