Hi, I have a damp or condensation problem in 2 rooms.
1. Kitchen. The inside on an external wall has paint that has bubbled and flaked. Last year, I rubbed this down to the plaster, painted it with upva/water mix, then with paint...the following morning it had flaked. The kitchen does has an air vent in the damaged wall, as well as a extractor.
2. The bedroom above the kitchen also has bubbled flaked paint, with what looks like salt deposits on it. Again, this room does have a vent in it.
The roof of the house is a flat roof, but I have not cheked this out yet to see if it is damaged.
Any guidance would be appreciated
