Hi all,
We got our bathroom redone a couple of months ago, and the walls were replastered and repainted. Just recently, bubbles have started appearing just on one section of the walls. They only appear after showers, and when the bathroom has cooled down the bubbles disappear.
Our contractor is insisting that he's never seen this problem before, and that he had paid for quality bathroom paint for the painter.
Can anyone advise what could have caused it? Wrong paint / primer / waiting times not sufficient?
I attach a photo below, I hope it's clear enough.
Many thanks in advance.
