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.
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.
