I have removed 35 yr old wallpaper from a bedroom wall with a steamer, which was so easy. I have some of the old paint coming off on the wall joins.
Is there a simple way to "feather" these areas out? I have tried sanding, but the small area becomes quite large and sometimes the edges aren't smooth enough to start undercoating.
I'm trying to avoid stripping all the old paint off.
Cheers
