Honestly, I get the appeal of feathering wide, but I’ve started using those sanding sponges with a vacuum attachment, and it’s not nearly as dusty as it used to be. Plus, if you keep your mud thin and do a couple of light coats instead of one heavy one, you don’t end up sanding forever. I know it’s a little more work upfront, but my walls actually look smoother now. The mud stains are still a thing though... I think that’s just part of the experience.
Has anyone tried just using regular sanding blocks instead of the sponges with a vacuum? I keep eyeing those fancy setups but can’t really justify the extra cost for a couple rooms. I’ve been sticking to thin coats too, and yeah, you’re right—makes a massive difference in how much you actually have to sand.
About the mud stains, do you mean those spots that show through after you paint? I’ve had that happen even when I thought I wiped everything down. I’m starting to wonder if it’s just the cheaper primer I’m using or if there’s some trick to sealing those areas better. Does paying more for a “stain-blocking” primer actually help, or is that just marketing? I’d rather not redo a wall because the stains bled through again...
Stain-blocking primer actually does make a difference, especially with those weird mud spots that seem to bleed through like ghosts no matter how much you wipe or sand. I used to cheap out and just grab whatever basic primer was on sale, but after repainting the same patch twice in my kid’s room (crayon art phase), I caved and got one of those thicker, “stain-blocking” types. Honestly, it worked way better. Not magic, but it saved me from that annoying shadowy look you get after painting over joint compound.
For sanding, I’ve gone back and forth between the basic sanding blocks and those fancy sponges. The blocks work fine for small jobs if you keep your coats thin and stay patient. The main downside is the dust—seriously, it gets everywhere. I’ve tried to MacGyver a vacuum attachment, but it was more hassle than help. If you’re only doing a couple rooms, I’d just stick to the block, open a window, and maybe wear a mask. Unless you’re sanding overhead, then all bets are off... gravity wins every time.
One thing I found that helps with stains and weird spots: after your last sanding, run a barely damp cloth over the joints, let it dry, then prime. Sometimes it’s just fine dust that’s messing with the primer’s grip. And yeah, the paint brand can matter too, but honestly, a decent primer is usually the real hero.
If you’re worried about chemicals, there are low-VOC stain-blocking primers now. They’re not perfect, but it’s a little less nasty for the air in your house, and you don’t have to feel like you’re painting in a gas chamber.
Anyway, thin coats, decent primer, and patience—seems like that’s the real trifecta. And maybe a podcast to keep you sane while you sand...
I’m right there with you on the stain-blocking primer—learned that lesson the hard way after a client’s “mystery spots” kept haunting a living room wall. I do think the low-VOC options have come a long way, though I still find the coverage a bit hit-or-miss compared to the old-school stuff. Curious if anyone’s tried those “self-priming” paints for tricky patches? I’ve had mixed results, but maybe I’m just too much of a perfectionist. Also, does anyone else feel like sanding overhead is some kind of cosmic punishment?
Self-priming paints are one of those things that sound too good to be true, right? I tried them on a patchy ceiling and honestly, it just didn’t cut it—ended up with weird flashing and had to go back over with a real primer anyway. Maybe I’m just picky, but nothing beats a dedicated primer for stubborn spots. And sanding overhead? Pure torture. I started using a pole sander with a vacuum attachment, which helps a bit, but my arms still feel like noodles after.
