I dont think just filling it with joint compound would be enough, since its breaking from ongoing house movment.

I’ve used Drywall Joint Tape to properly repair these, allowing ongoing house movement without these cracks reoccuring.

Its defiantly more labor intensive, since you need to apply drywall plaster to spread over, then sand it down smooth, before doing a larger paint.

I grabbed some tape and will do that repair. Thankfully, I have taped drywall before so this is not new. I don’t think my wife will be thrilled that this is going to add a day or two until we can paint, but she will agree that it is better to do it right than fast.

If you get setting compound (the powder you mix with water rather than the pre-mix stuff), it sets much quicker, and you can sand and paint the same day

EssentialNPC OP ,

Thank you for that tip!

Grabthar ,

Of note, that stuff works great, but you need to be very sparing with it, as it very difficult to sand compared to the premixed stuff. Make sure you have it as close to the way you want it to look as you are able before you let it dry. A lot of drywallers use this stuff for pre-filling poor, uneven drywall board work before taping, as it is very hard stuff. But it can take a lot longer to dry that way than the bag would suggest. Sheetrock 90 turned into Sheetrock Maybe Tomorrow in my kitchen reno after I used it to replace sections along the edges of some damaged drywall that tore out when I removed the old tile backsplash.

Ditto this. I use Easy Sand 45. You get 45 minutes to work, before it sets up. Definitely ready to paint the same day. I also recommend folding your tape in half and tearing off the hard edge. When I do this, I find the tape to be a bit more forgiving and easier to hide. Cheers!

Take a rasp and putty knife and try to remove some material (not into the drywall, just take off paint and mud layers) so that you have a recessed area for the tape the go. This will prevent you from needing to build out the area so much to hide the repair, and is very necessary at the edge of the corner bead otherwise the metal edge that forms the corner won’t actually be the corner anymore (so there’ll be a weak and ugly “wave” in the line of the corner).

Personally I don’t think you would need the tape. It’s usually for the gaps between sheets of drywall which can be significantly wider than these cracks. You should be fine just filling with the drywall compound and sanding.

For this you might end up seeing the thickness of the tape beneath the new layer of paint afterwards.
