Hi,
I recently moved into an new house and renovated the bedroom, removing the old wallpaper and painting the bare plaster with a primer and two coats of a "Crack-Free" paint.
The room suffers quite badly from condensation, especially behind the bed, where we have to leave a gap to stop moisture leaving a tide-mark on the wall.
Recently I have noticed that some areas of the paint behind the bed (Just above the skirting board) has started "blistering" and flaking. This is sometimes accompanied by some mould growth and a general "mouldy" smell.
Normally I would put this down to being caused by the excessive condensation, however this is coming from BEHIND the paint. Therefore is seems that it is a damp problem in the walls (Although the wall does have an existing Damp Proof Course).
Could anybody offer me any advice over what might cause this "blistering" effect and whether it is likely Rising/Penetrating damp or just caused from condensation?
Many thanks for any help,
Neil Sherwood.
