Rather than use sandpaper to smooth the joint compound, try using a scouring sponge. This is much faster and it doesn’t create any dust. Get the sponge, dip it into a bucket of warm water, and squeeze out the excess. Next, use the scouring side of the sponge to smooth out the joint.

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.
Can you only do 2 coats of drywall mud?
If your wall has distinct crevices, cracks, or textured areas, or if your brand of drywall mud isn’t offering enough coverage, you may have to do a couple of additional coats of compound. However, in general, you’ll need one coat to fill in the seams and three more coats after taping.
Can you sand drywall mud with a wet sponge?
When using a sponge, a wet sanding method is often most effective. This method softens the compound, or mud, and dampens the dust formed from sanding to keep it under control. Fully submerge the sponge in water and squeeze out the excess.

What grit sandpaper do you use for drywall?
Choose fine sandpaper for the best results
But because modern lightweight joint compound is so soft, you don’t need heavy-grit paper to sand it. Coarse-grit paper or sanding screens will leave undesirable sanding marks. We recommend 120-grit or 150-grit paper for the best results.
How do you sand drywall after mudding?
Avoid sanding off so much joint compound that you expose and scuff the underlying drywall tape. If that happens, use a wide blade and more mud to build out the seam from the high spot to both outside edges, let the mud dry, map the seam again and then sand it. Fill.
What is the difference between sheetrock mud and joint compound?
Joint compound is most often used when new drywall is hung.
Joint compound (also known as drywall mud or simply known by pros as mud) is also comprised mainly of gypsum dust that you mix yourself to a cake frosting-like consistency. You can also find it pre-mixed in a tub.
How long should drywall mud dry before sanding?

How smooth should finished drywall be?
The wall should be smooth with no ridges, tool marks or signs of fasteners and then finished with a coat of drywall primer.
Do you tape or mud drywall first?
All-purpose mud is commonly used as a first coat because the bonding agents in the mud cause the drywall tape to hold better. All-purpose mud is harder to sand and not often used as a finish coat. Topping mud is a form of dry mud that is lighter than all-purpose. It is best used for final coats.
How many coats of mud do you put on drywall tape?
Applying Mud
You need to lay one layer of mud onto the bare wall to hold the tape, and you can usually lay another immediately after you lay the tape and scrape it. After that coat dries, you topcoat with a third layer, using a wider knife than you used for taping.
What product should be used to smooth over a drywall patch?
Fill the widened crack with lightweight spackle using a putty knife. Apply a thin coat of spackle over the entire area. Smooth it with a putty knife. Allow the spackle to dry for 15 to 30 minutes or the time recommended by the manufacturer.
Do you need primer after skim coat?
It’s important to apply primer over the finished skim coat before painting with the top coat. Primers fill tiny voids in the drywall compound for proper sealing and adhesion.
How thick should a skim coat be?

The skim (finish) coat is responsible for smoothness.
The skim coat is applied to the backing coat at a thickness of 2-3 mm. It is not designed to flatten, but is literally just a smoothing off coat.
Why does my drywall mud keep cracking?
The most common cause of cracking in freshly applied drywall mud is when it is applied too thickly. This exacerbates the issue with evaporation-based drying and can even crack curing compounds. Past this point, applying more drywall mud will cause the cracking to worsen if done improperly.
Can I use orbital sander on drywall?
Orbital sanders are great for small home improvement projects, including drywall. They can help cut your drywall finishing time in half compared to hand sanding. They also come with their risks. If you press too hard or sand unevenly, you can completely ruin your drywall job.
How many coats of primer do I need for drywall?
You’re painting unfinished drywall or plaster.
Two primer coats are recommended in this scenario because much of the first primer coat will be soaked up by the wall; the second coat will replenish any primer absorbed by the surface and hide any flaws in the wall.
