We've just moved into a terraced mid-1800s house and have begun redecorating.
When removing some wallpaper from a lower-ground floor room, the paper pulled away a layer of paint, and in some places some plaster too.
On closer inspection it looked like some areas of the plaster had blown, and crumbled away fairly easily.
The revealed remaining plaster looks like it is potentially slightly damp in some areas, as it's darker than other places, and feels slightly cold to the touch - but there was no signs of any mold to the (mostly white) wallpaper or paint.
Tapping on the plaster below, above, and to the side of this patch it seems solid and still attached to the wall.
What should be my next steps? I'm assuming if it is an issue with damp there's no point repairing the plaster with an easifill type product until the damp is sorted?
I don't know enough about plastering to know what the surface is that has been revealed now the top plaster skim has crumbled off?
I'm slightly unsure where the damp would be coming from as the rest of the wall seems fine, but being a lower ground floor room I suppose it would be prone to it..
Any thoughts much appreciated!
