Bit of history on the problem wall...
Is a 1930s house with both lathe and plaster and plaster on brick walls.
In this case it's the latter causing me grief. The original plaster is about 12-15mm thick. The wall was in poor condition and was professionally skimmed. Cracks appeared before I even painted it and it was skimmed again. The wall was painted but cracks reappeared. It was left like that for quite some time and no new cracks appeared. I filled the hairline cracks just about 3 weeks ago and repainted. All looked great but the cracks have reappeared.
I suspect that filling and painting is pointless and the problem might only be fixed by the extreme process of taking off all the old plaster, boarding and skimming. I really don't want to go to those lengths, so I'd love to hear your other suggestions on fixing this annoying problem.
I'm sure you know what a hairline crack looks like but I've posted a photo anyway.
