Hey!
I have a house from the late 1800s with a chimney that has been wallpapered 42 times, which we have chosen to remove the wallpaper from because we want to paint it instead.
The problem is that it has cracked in the plaster.
I have torn down the old plaster but am a little unsure of how much to remove and which plaster to use.
I would be eternally grateful to get answers in this thread!
