If you buy the bags of drywall mud and mix it yourself, you can get it to dry quicker, they sell 10 minute mud and 45 minute mud, the 45 sets up fairly quick, the 10 on the other hand sets up in less than five so work fast, but it is good for large spots that you need to pack mud in, but dont want it to crack like the premixed stuff will, cause it sets up to fast to crack
