A primer is recommended for joint compound. Using a primer seals the mud and actually uses less paint with a even finish in the long run. If you’re not doing a LOT of patches, consider using a better patch. Joint compound is different from vinyl spackle, and some types of spackle come pre-primed now.
Ready-mixed mud comes in three basic varieties: Taping compound dries hard and works well for embedding paper drywall tape over seams. Topping compound is less durable but shrinks very little and sands easily, so it is effective for covering taped seams and providing a final, smooth finish coat.
Thereof, What do you use to seal drywall?
There are products however, which are primers and sealers in one, called primer-sealers. They do the job of both sealing the new drywall and evening out the different textures between the drywall paper and joint compound, as well as creating an excellent surface for new paint to adhere to.
Also to know is, Can I paint directly on joint compound? Before the pros paint walls, they fill holes and patch cracks with joint compound. But if you paint directly over the patched areas, the compound will suck the moisture out of the paint, giving it a flat, dull look; a problem called “flashing.” And those spots will look noticeably different than the rest of the wall.
Subsequently, question is, Can you seal joint compound? Priming the wall seals the joint compound, which has a different texture than the rest of the wall and absorbs more paint than the drywall. Priming blends the joint compound and the drywall, so the surface is uniform. Use a primer designed for painted walls.
Also, What is topping compound?
Topping compound is the ideal mud to use after the first two coats of taping compound have been applied to a taped drywall joint. Topping compound is a low-shrinking compound that goes on smoothly and offers a very strong bond. It is also highly workable.
Can you roll on joint compound?

Can you skim coat with joint compound?

What is the difference between setting compound and joint compound?
Setting-type joint compound is an alternative to all-purpose mud for taping. This type of joint compound hardens chemically, and because it sets quickly, it reduces the overall time needed for finishing. It also resists cracking better than drying compounds, but it does have disadvantages.
Can you skim coat plaster with joint compound?
The best way to restore the wall surface is by skim-coating it. Skim-coating is the technique of applying thin layers of gypsum-based joint compound over the entire surface. The layers are so thin that even after applying several coats, the total thickness of all the layers together is less than an eighth of an inch.Mar 14, 1999
Does drywall need to be sealed?
Why Do You Need a Sealer On New Drywall? You need a sealer on new drywall because the white joint compound on the seams and in the corners absorbs paint faster than the paper surfaces of the drywall that don’t have joint compound on them. Different materials absorb liquids at different rates.
