A couple of years ago we noticed some mould and posted some pictures and the good people here stated spot moulding, which I confirmed by other pics of condensation caused spot mould on walls.
Now we are ready to paint over it, but are unsure how to prepare the walls. We are sure the problem is historical as we get very little condensation now and it clears in minutes with a little ventilation every morning. We gad also stopped drying clothes in the house years before and we also now have decent double glazing, fitted properly.
The question is, how do we prepare the walls for painting over? We don't mind what we gave to do, or the cost within reason, we just don't want to slap up £70 of paint on the walls and then still have a problem if it shows through.
