It's not the easiest job to start on but basically get a patch of lining paper, soak it for five minutes with paste, place it over the damaged area and cut with a very sharp clean blade through both layers of paper, then take the old paper out from underneath the new piece and paste the new piece in.
Unless you are some kind of wallpaper savant this is not going to work first time out but you'll get close. Fill the gaps between old and new paper with a decorators filler.
I had some leaks through my ceiling and some paper was removed/damaged. Below the (many layers) of paper is board. Roof has now been fixed and I want to repaint this without it looking like chunks are missing. Obviously one solution is to get it plastered but that's beyond my DIY level.
I asked on here a while back and I think a suggestion was to splice some paper in there. I didn't get round to asking at the time but how would I do this, wallpaper paste or something? And what would be the best way to blend in where the old meets the new so there isn't an obvious patch?
Cheers
