My new IP has some mould on the ceiling and walls of one of the bedrooms. Im moderately sure that its a lack of tenant ventilation issue, but may well be from the roof. I don't want to look too hard as I have a plan to demolish the house, but want to freshen the walls with a repaint and get a tenant in until it's ready to go. The walls are the panelled presumably asbestos type sheeting. Any idea of the best way to clean then paint? Is the type of paint then important?
