I’m wondering, what’s the best way to repair those cracks in the corners of the drywall? There are two corners in one room that go all the way from the floor to the ceiling.
Seems to be wallpaper that has been painted over. Remove it and apply paper joint tape and durabond. There are plenty of videos on YouTube for reference.
Take a look behind it. Seems like there’s a corner that’s rotted out.
The only solution is to tear it out and put in a new one.
Seems like it’s old-fashioned plaster, not drywall
Yeah, I was thinking the same thing, .
Seems like they opted for seam tape over corner bead, let’s cut or scrape it out and put in metal corner beading
Let’s work on the corner beads and compound. We’ll feather it out to match. Keep in mind that old houses expand and contract, so just patching it with compound might lead to cracks again.
Let’s cut it out, re-tape, and mud it up
Seems like they skipped using corner bead or paper tape. Corners are prone to damage from the house’s movements. That’s why it’s important to use paper or corner bead instead of just compound.
Caulking could be the simplest solution at times
Clean up the surface until it’s smooth and apply mud and tape, then blend it out after smoothing the tape
Pretend you didn’t see that
Swap out the loose part, add fresh tape and mud to the interior corner
Cleaning it out and applying caulk works wonders. I personally use a chalk tool to spread it evenly.
