I just bought my first house, and before moving in I’ve been doing a little bit of small-scale DIY stuff. I just removed an awkwardly-placed walk in closet in the primary bedroom, and the paint on side wall it was connected to started peeling (no big deal), but then I noticed the peeling was pretty thick. Maybe they put mud and paint over wallpaper? I thought the side wall might be plaster before I took apart the closet wall (which was added by the last owner). For context, the house was built in 1910, but I think the closet was added in 2000/2001.
I also can’t totally tell what’s beneath the peeling. It looks like maybe it’s just wood? There’s this screw that’s now exposed:
How can I patch this? I was thinking maybe I can cut a straight line in it and peel to there, then sand the edge, mud over it, sand, prime, and paint. Would that work? What kind of mud should I use? I’ve never patched a wall before, and I’m going to practice a little first just by patching some holes from where the closet shelves were drywall anchored in (to a different wall that is drywall). Any help is appreciated – thank you!
I think I’m going to at least start by scraping away at the rest of the wall and then either applying a skim coat myself or call a plasterer to do it for me. Thanks for the help!
