Hi All Just been in me cellar and seen the below (Attached Pic) in the corner of an external wall, what is it? Damp, mould ? and how can I treat it. it looks like cotton wool ? Thanks
Rot. You need to find the cause - probably damp, prevent the damp then kill the mould before it causes more damage.
Ive seen this before, actually in a cellar in Belguim, it is caused by keeping too many schoolgirls in the cellar for prolonged periods of time. Free them and the problem should dissappear.
