I recently dealt with a pretty serious water leak from my washer that ended up swelling the drywall seams on the ceiling below. To manage it, I cut open the seams to let the moisture escape and dry everything out. Now, I have all-purpose joint compound, a taping knife, and some sponges ready, but I forgot to grab the tape. Should I definitely pick that up? Also, when prepping the existing texture and paint for repair, should I stick to using a utility knife to cut it back or is there a better tool for the job? I appreciate any tips you can share!

Honestly, it doesn't look too terrible! Make sure the drywall is still secure, adding more screws if you need to. Put some mud in the seams, tape them, and then finish off the drywall. Don’t rush it; take your time with multiple coats. For that knockdown finish, crumple up some aluminum foil, dip it in the mud, and use it to recreate the texture—it works like a charm! I recommend using a 45-minute mud that you mix yourself; it's super easy to work with.
First off, you’ll want to cut out all the damaged drywall until you can see the ceiling joists. That way, you can secure a new patch of drywall in place. Make sure to tape it up after that, then apply joint compound and sand it down until everything is nice and smooth. If you’re looking for more detailed guidance, check out the Vancouver Carpenter on YouTube; he's got great info on the tools you'll need and the whole process!
Just be prepared—you might need to replace up to 6 sheets if the water affected edges on several of them. If you had just one sheet, I’d say go for it, but if multiple are damaged, better to replace them.

Good tip about the extra screws! I’ll start with mud and tape the seams. The aluminum foil idea is clever—never thought of that! How would I check if everything's securely fastened to the joists? It’s been years since I did drywall, and this is my first time dealing with water damage.
