Just wondered whether anyone could assist me with a problem at my house - have searched the forums, but to no avail.
I recently moved into a 1960's house and found that on the ceiling of one of the downstairs bedrooms it had a lot of white stipple marks. I can only describe it as a big area of the ceiling that has been painted, but the paint had a load of sand in it - hence the pock marks. A lot of the marks track along the edges of the plasterboard, and also all on the wall around a (newish -5yrs) UPVC window.
I was just wondering whether anyone has encountered such a thing, and whether it may be damp related, although most damp is of a darker colour.
Any feedback would be greatly appreciated before I start ripping up the flooboards upstairs !!
