My external walls are not build with cavities (built in 1932). Any furniture , curtains or e.g. a toy box placed by the wall starts to collect dark mould patches like the air is not circulating behind them or something. This appears on the curtains and on the wall paper.
What shall I do to:
a) get rid of the mould
b) protect against the mould coming back
Cheers in advance.![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
