Totally with you on the lighting thing - I learned that lesson the hard way too. Another tip that's saved me a ton of frustration is sanding lightly between coats. I used to just slap on another layer thinking it'd smooth itself out eventually (spoiler: it didn't). Now I do a quick, gentle sanding after each coat dries, wipe it down with a damp cloth, then apply the next coat. Takes a bit more patience but the results are worth it...and fewer surprises when daylight hits.

Have you ever tried thinning your mud a bit too? I used to fight with thick compound forever until someone suggested adding a tiny bit of water. Game changer...way easier to get smooth coats without sanding my arms off. Might be worth a shot next time you're tackling drywall.

Yep, thinning the mud a bit is a solid tip. Took me a while to figure that out too - used to dread drywall days. Now I mix it just thin enough to spread easy but not drip everywhere...makes life way easier. Good call.

Totally agree, thinning mud is a game changer. Another thing that helped me was switching to a wider knife for the final coat - like 10 or 12 inches. Covers seams smoother and cuts down sanding time...and sanding is the real enemy here, right?

Yeah, wider knives definitely help. I usually go with a 12-inch for that final pass, but honestly, the real lifesaver for me was getting decent lighting set up. I used to think my joints looked perfect until the paint went on...then every little bump and ridge jumped out. Now I throw a work light at an angle to catch imperfections early. Saves me from sanding nightmares later on.

Good call on the angled lighting - I learned that lesson the hard way too. Nothing worse than feeling confident about your joints and then seeing every little flaw pop out after painting. I've found that natural daylight also helps a ton. If you can, try checking your work at different times of day. Sometimes imperfections that hide under artificial lights become painfully obvious in sunlight.

Also, totally agree about wider knives. I used to think an 8-inch knife was plenty, but once I switched to a 12-inch, it really upped my game. Now I'm tempted to try a 14-inch just to see if it makes any noticeable difference.

One thing I'd add is being patient between coats. I used to rush things, thinking I was saving time, but it always bit me later with extra sanding or having to recoat. Now I give each coat plenty of drying time, and the sanding is way less tedious.

Anyway, sounds like you've got a solid system down. Drywall finishing is definitely one of those skills you get better at with each project...but man, it's still my least favorite part of remodeling.

Totally agree on patience between coats - learned that lesson after sanding forever on my first project. Curious if anyone's tried eco-friendly joint compounds? I've heard mixed reviews about their smoothness and drying times...would love some firsthand experiences.

I've used eco-friendly joint compound a couple times - it's decent, but yeah, drying time was noticeably longer. Smoothness wasn't bad though, just took a bit more effort to feather out nicely. Worth trying if you're patient and wanna keep things green...

Yeah, totally get what you're saying about the drying time. I tried the eco-friendly stuff on a small bathroom remodel last summer, and at first, I thought I'd messed something up because it just wouldn't dry. Kept poking at it every hour or so, haha. But once I got used to the slower pace, it wasn't too bad. Actually found it kinda relaxing - forced me to slow down and pay attention to details I might've rushed otherwise.

Smoothness-wise, I agree, it's workable. Took me a bit of practice to feather it out nicely, but by the end of the project, I felt pretty good about the results. Definitely not as quick as traditional compounds, but knowing it's better for the environment made the extra effort feel worthwhile. Glad to hear someone else had a similar experience...makes me feel less impatient, lol.

Had a pretty similar experience - thought I'd screwed something up at first too, haha. Once I accepted the slower drying time, it actually improved my technique. Curious though, did you notice any difference in sanding ease with the eco-friendly stuff? For me it felt a bit softer, which made sanding quicker but also meant I had to be careful not to overdo it...

"Curious though, did you notice any difference in sanding ease with the eco-friendly stuff? For me it felt a bit softer, which made sanding quicker but also meant I had to be careful not to overdo it..."

Yeah, totally noticed that too - it's definitely softer, almost like sanding chalk sometimes. Took me a minute to adjust my usual sanding rhythm. Here's what ended up working really well for me:

First, I switched to a finer grit sandpaper (around 150-180 grit) than I'd normally use, because the eco-friendly stuff sands down quicker and smoother. Then I started using a handheld sanding sponge instead of my power sander for tighter control. It slowed things down a bit, but honestly, it was worth it - I wasn't accidentally sanding away all my hard work anymore.

Also, quick tip: angle your lighting from the side when sanding. It highlights imperfections better, so you can spot uneven areas before you go too far. Learned that one the hard way after sanding a joint into oblivion, haha.

Yeah, I ran into the same thing - felt like I was sanding marshmallows at first, haha. One thing that helped me was doing a super light pass first just to knock down the high spots, then stepping back for a sec before going in again. Also found that using one of those flexible sanding blocks gave me better feel and control. Definitely second the lighting tip...nothing worse than thinking you're done, painting it, and realizing you missed a spot. Been there too many times.

Haha, sanding marshmallows is spot on...been there myself. Another thing that really helped me was thinning out the joint compound a bit more than usual - makes it way easier to feather out smoothly. Also, swapping to a wider knife after the first coat saved me tons of headaches. And yeah, lighting is key, but I also run my hand over the joints with my eyes closed (sounds weird, I know)...you'd be surprised how much your fingers catch that your eyes miss.

Thinning the compound definitely helps, but I learned the hard way not to go too thin - ended up dripping everywhere and making a bigger mess than I started with. The wider knife trick is gold though, wish I'd known that sooner. Funny you mention the hand test...I do something similar, except I use an old sock over my hand to feel for bumps. Anyone else tried that sock trick, or am I just weirdly attached to my drywall sock method?

Haha, the drywall sock method...honestly, that's pretty clever. I've never tried it myself, but now I'm curious - does the sock texture help you feel imperfections better, or is it more about protecting your hand from dust? I usually just rely on my fingertips, but I can see how a sock might give you a smoother glide across the surface.

And yeah, totally agree about thinning compound - there's definitely a sweet spot. Too thick and it's impossible to spread evenly, too thin and you're basically painting your floor with drywall mud. Been there, done that. The wider knife was a game changer for me too; wish I'd discovered it sooner.

Anyway, don't worry about being weirdly attached to your sock trick. We all have our quirky little methods that work for us. If it gets you smooth walls without losing your sanity, I'd say stick with it!

Yeah, wider knives save a ton of headaches. Never tried the sock trick myself, but I do run my hand over the joint with a thin plastic grocery bag - sounds weird, but it picks up imperfections pretty well without sanding my fingerprints off...

Totally agree on wider knives - makes all the difference. Haven't heard of the plastic bag trick before, pretty clever actually... I'll give that a shot next time. Personally, I like using a bright work light at a sharp angle to spot imperfections. Sounds obvious, but you'd be surprised how much extra detail pops out under harsh lighting. Caught plenty of little bumps and dips that way without having to rely on touch alone.

I second the angled lighting trick - it's saved me a ton of headaches. Another thing I've found helpful is lightly sanding between coats rather than trying to get everything perfect at once. I used to obsess over getting each layer flawless right away, but honestly, building up thin layers and sanding gently in between gave me way better results. Takes a bit more patience for sure, but beats going nuts chasing imperfections later...

Totally agree on sanding between coats - it really helps. Another trick I picked up is thinning out the joint compound slightly. It goes on smoother, dries quicker, and honestly cuts down sanding time later. Might be worth a shot if you haven't tried it yet...

Definitely agree with thinning the compound - tried it last weekend and it made a noticeable difference. A couple other things that helped me:

- Using a wider knife on the final coat really smoothed things out nicely.
- Good lighting is key... I didn't realize how uneven my joints were until I brought in an extra lamp.
- Also, don't rush drying times. Learned that the hard way when I sanded too soon and had to redo a section.

Still not perfect, but getting there slowly!
