Hi Folks,
I live in a tenement flat with a common close and a couple of weeks ago I noticed that a patch of paint (emulsion) on my bit of close wall was "bubbling". Since then it's got bigger and where it has flaked off it looks like the some of the plaster underneath has decomposed (bubbled up) in places too. The patch is now about 12" by 4".
I've traced back to where the patch would be inside the house and it's about halfway up a tiled wall in my bathroom (about a couple of feet above the bath line). Grouting seems to be intact but it is a wall that gets splashed a bit when the shower is used.
Is it likely to be water ingress (egress?) from the bathroom? The wall is pretty thick so I am dubious. Also, the plaster seems dry but if you rub it a bit with your finger it seems to be more greasy or oily on your finger than damp. Should I be worried?
As you can tell, I am not a builder!
Regards,
Buckie.
