The wall that is against the front of the house gets dreadfully mouldy in the winter. I moved the big oak cabinet and the wall and cabinet are covered in black and green mould. It's horrible! I leave the windows open at least an hour a day. Anyway, what is the best paint to use? A damp seal undercoat or the additive that you can buy to add to paint? How long between treating it with HG mould remover and painting it? Thanks
