Filling over lining paper?
Discussion
As part of a bigger job (which was all done really well, can't fault much of it) we wanted some lining paper put up and two coats of paint over it.
Came back first day and there were long bubbles all over the place, like the paper hadn't been soaked long enough before putting it up, or not brushed out properly when hanging - there are some imperfections in other parts of the wall but this section (0.8m x 1.2m) was over a level plaster skim so no excuses:
Flagged this up, half thinking that it would all need to be re-hung as there were way too many large ones to pop and flatten down.
Came back second day to find big patches of what looks like plaster but almost feels like latex, and there are definite ridge lines to be felt between the patches and the paper:
Really didn't quite know what to say. The walls have a patchily painted first coat and there are STILL air bubbles in it.
Would you let them try to put it right, or would you deduct the cost of it and pay them on their way?

Just a guess but perhaps the paint was put on before the wallpaper had dried out properly - so the paint was able to expand the paper and force it away from the wall. Or maybe it was badly papered to start with. Was it OK before being painted?
No, the first photo is pre-paint, each drop had long air bubbles like that. It's the filler (whatever material it is) that confuses me, it's like a bodge on top of a bodge.ladderino said:
Get rid of them, they have no idea what they are doing.
Can possibly still be saved - but the way to get rid of air bubbles is to cut through into them, paste and roll it down. If they've lacquered over air bubbles with caulking then it's going to be more difficult.
I'm going to give them the benefit of the doubt and see what they come up with, who knows, they might do this every time and the painted-over filler is invisible, but the whole thing reminds me of this:Can possibly still be saved - but the way to get rid of air bubbles is to cut through into them, paste and roll it down.

If it's s
t they can strip it back again, we're not in a rush.
