In this regard, is there a difference between joint compound and drywall compound?

Drywall Joint Compound The main ingredient in joint compound -- or mud -- is gypsum, and it's the product that you use for taping and finishing drywall seams. You can also use it to patch holes, although it takes longer to dry and shrinks more than spackling paste.

Additionally, can I paint directly on joint compound? Priming blends the joint compound and the drywall, so the surface is uniform. Use a primer designed for painted walls. Apply with a paint roller and use a brush for smaller areas. When the primer dries, lightly sand the wall with very fine sandpaper to remove any nubs in the paint.

Also asked, do you need to mix joint compound?

Mixing tools drill for the paddle mixer. If you've just opened a bucket, remove about a quart of the joint compound to make room for water. Then add about two or three cups of water and start mixing the compound. The best consistency for joint compound depends on its purpose.

Is joint compound the same as plaster?

Mud and Hot Mud To make a gypsum plaster, manufacturers add cross-linking chemicals to bind the mixture. Without these hardening chemicals, the gypsum paste is called drywall joint compound, or mud -- with them added, the mixture variously becomes patching compound, plaster of Paris or hot mud.
