Any recommendations for joint compound?
I need a small amount of joint compound for random drywall repairs. Is there any real difference between different brands? Do any of them last longer than others after they have been opened? Any other considerations with knowing? Since I don't need a lot I don't mind spending a few extra bucks, but I'd like to know if it's actually worth it.
There are many types of drywall compound (mud) for different use-cases and skill levels. The premixed bucket stuff sets by air contact - this stuff is usually more forgiving and sandable, just be ready for some shrinking and being patient with allowing to dry fully. The all purpose, lightweight, plus-3 stuff can do most jobs. Many pros will use powdered "hot mud" that sets by chemical reaction - you'll see numbers like 90mins, this is time you get to use it (assume you'll actually get half that before it gets weird). They use this because they are on a job and can get multiple coats done in a day but it takes more skill to get it right. Those are usually less forgiving and harder to sand. Also bucket mud goes rancid after sitting, but what you need for the job but don't expect it to be there for next project.
Bucket mud going rancid after sitting I can attest to. Crack open the lid before you buy it. My local Despot had an entire pallet of the stuff that'd gone bad from sitting around god-knows-how-long, and then tried to give me shit for returning it like 15 minutes after I bought it.
I always use the green lid USG "all purpose" stuff. I am likely inept enough not to notice the difference between that and other options, and it's always done fine by me. I can tell you from my own observation that the "dust control" moniker on the USG blue bucket stuff is horseshit. And yet, it costs twice as much as the normal stuff.

For the odd small drywall repair around the house, I like to keep on hand a small packet of 15 minute mud powder. You can mix up a little, apply it, and then sand and apply another coat soon after, so you can get the whole job done in an afternoon. And it never goes bad.
I take it back.... it's 5 minute mud. Sounds like an insanely short working time, but it's just to take care of only a few little dents in a small area, and it gives you very fast turnaround.
