Do you have to sand drywall after mudding?

Sanding the drywall after the joint compound, or mud, dries creates a smooth and even surface for applying primer and paint.

Do all drywall joints need taped?
All drywall seams need to have tape embedded in joint compound. The tape strengthens the joint, and the joint compound, or mud, is the adhesive that holds the tape in place. But there’s a lot more to hand-taping beveled drywall seams than slapping a bunch of mud on the wall and running tape.
How many coats of mud do you put on drywall tape?

Can you sponge drywall mud?
Just use your sponge to dab, wiggle, and pat the drywall mud—which is used to conceal the tape that holds sheets of drywall together—until it matches the texture you’d like to duplicate.
Why is my sheetrock mud cracking?

Do you have to skim coat the entire wall?
Prime the ENTIRE wall to seal any loose paper and to help ensure a nice, even finish. These are thin layers that won’t fix holes or torn-away paper, or make uneven sections level. Patch these problems with setting-type joint compounds.

How do you fix uneven drywall mud?
Fill the largest portion of the seam’s gap with drywall compound. Press the knife and mound of compound onto the seam and draw the knife across the seam’s length. Fill the deepest part of the gap with the first coat; do not attempt to apply a broad layer of compound on the first coat. Allow the coat to dry.
