What Is Joint Compound?
Quick answer
The slow-drying "mud" for big drywall jobs. Overkill for nail holes, where spackle wins.
The gypsum paste ("mud") used to tape drywall seams and skim large patches. It goes on in thin coats, shrinks as it dries, and expects two or three passes a day apart, which makes it the right tool for big repairs and the slow, wrong tool for nail holes, where spackle wins.
