Wet-sanding drywall compound is a slower process than traditional sanding. If you’re interested in speed, you’ll want to dry-sand. Nor does wet-sanding produce a perfectly smooth surface. Because you are using a sponge―which is flexible―your finished wall may exhibit gentle waves.

Can you wet sand dry drywall mud?
Most can accommodate wet or dry sanding and are great for getting into tight corners and ceilings. 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.
Is wet sanding drywall better?
Wet sanding is time-consuming: If you’re really in a hurry to finish prepping drywall for paint, you’re better off dry sanding. Though keep in mind, when you dry sand, you’ll still spend quite a bit of time cleaning up the dust.
Can you sand drywall mud with a wet sponge?
Wet-sanding is the process of using a damp sponge to smooth out and remove excess taping compound after it dries. When moistened with a sponge, drywall compound begins to dissolve and loosen, and it can then be smoothed out. Wet-sanding is normally done with a very thick, stiff sponge.
How do you minimize dust when sanding drywall?

Can you sand joint compound with a sponge?
The Drywall Sanding Process
Using a sponge on drywall achieves the same thing, but instead of using sandpaper, you use a wet sponge and wipe it using a circular motion across dried joint compound to soften and smooth the uneven areas.
How many coats of drywall mud do you need?
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.
Should I sand between coats of drywall mud?
After the first coat has dried completely, you will need to sand and apply two more coats to the fasteners, sanding between each coat. Keep your knife clean by drawing it over the edge of the mudpan or hawk.
What grit do I use to sand drywall?
Preparing Surface
Make sure the surface to be repaired is clean and smooth, and trim away any frayed drywall edges from the hole. Start smoothing the surface by sanding with 100 grit sandpaper, 120 grit drywall sanding screen or a Medium grit sanding sponge. We recommend using an Extra Large Sanding Sponge.
What grit sandpaper do you use for drywall mud?
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.
Can I skim coat without sanding?
You don’t have to sand between coats; just knock off lumps or proud mud lines with a 5- or 6-in. putty knife to avoid streaks in the next coat. Brush off the wall and you’re ready for the next coat.
What’s the difference between wet sanding and dry sanding?
What’s the difference between the two? Wet sanding, which is sanding with the addition of water to act as a lubricant, is less abrasive than dry sanding, and results in a smoother finish. It’s best to wet-sand the final finish of a project. Dry sanding removes more material, and smooths rough material quickly.
Why is my sheetrock mud 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.
