Its not something I’ve seen before but the new paintwork in our kitchen bathroom extention has started to bubble where it is painted in gloss..
When we tried pushing one of the bubbles it burst and water ran out. I don’t know where its come from. We had some problems when the work was done, but I thought it might be coming down from the roof? It’s not urgent but worrying that it’s happened at Christmas. It’s going to possibly have to wait for the new year to be fixed.
