- Drywall dust is relentless. Even with plastic sheeting and vacuums, it finds a way into every nook. I’ve literally opened up sealed paint cans and found a fine layer on the rim—no clue how it gets in there.
- On the mud: I’m with you on the setting compound for base coats. It’s a pain to sand, but the reduced shrinkage and faster set times are worth it, especially if you’re on a tight schedule. I do think lightweight mud has its place, though—mainly for final coats or touch-ups. It feathers out smoother, at least in my experience.
- Sponge finishing is a solid move, especially for inside corners. I’d add that using a slightly stiffer sponge (not the super soft ones) gives you more control and doesn’t gouge the mud as easily. Just don’t overdo the water or you’ll end up with a mess.
- One thing I’ve started doing: after the first sanding, I’ll run a shop vac with a brush attachment right over the joints. It pulls up the fine dust before it has a chance to float around and settle everywhere else. Not perfect, but it helps.
- If you’re really trying to keep dust down, wet sanding is an option, but it can leave the surface a bit rough if you’re not careful. I’ve seen people use those sanding sponges with a vacuum attachment—mixed results, but better than nothing.
- Quick tip: always check your lighting before calling it done. Raking light (just a work light at a sharp angle) will show every imperfection you missed. I’ve had jobs that looked perfect until the sun hit them at the wrong angle...
- Last thing—don’t underestimate the value of a good dust mask. I used to think I could get by without one for “just a quick sand,” but after a few days of coughing, I learned my lesson.
Drywall finishing is one of those things where you never really stop learning tricks. Every room seems to throw a new curveball.
Every time I think I’ve sealed off the dust, I find it in my coffee mug the next day. I’m convinced drywall dust is basically sentient. Agree on the raking light trick—it’s brutal but necessary. And yeah, learned the hard way: “quick sand” = two days of regret.
Dust really does have a mind of its own... I’ve tried everything from plastic sheeting to negative air machines and still end up finding it in the weirdest places. Do you ever use wet sanding? I know it’s messier in a different way, but sometimes it helps with the airborne stuff. And about raking light—have you ever tried a handheld spotlight instead of a work light? Sometimes the angle makes all the difference for catching those sneaky ridges.
Wet sanding just makes a whole different kind of mess for me—water streaks, soggy dust blobs, and then you’ve gotta wait for everything to dry before painting. I get the appeal for less airborne dust, but honestly, I’d rather just use a good vacuum sander and deal with the regular cleanup. As for lights, I actually prefer a big LED panel over a handheld spotlight. Less fiddling around, and I can see the whole wall at once. Maybe I’m just lazy, but it works for me.

Man, I hear you on the wet sanding mess. First time I tried it, I ended up with puddles on the drop cloth and a weird chalky soup in the corners. Honestly, I’ve stuck with dry sanding ever since, just with a decent shop vac hooked up. The LED panel thing is clutch, though. I used to chase shadows with a flashlight and missed half the ridges... full panel just makes life easier. Lazy? Maybe. Efficient? Definitely.
