I’m not a great dyier, needed this done by weekend to place furniture delivery and TV , what sort of imperfections can I expect from this type of sanding work after priming and painting over it ? It feels smooth to run my hand across it c
Whatever imperfections exist will look way worse when painted and way way worse if the light source in the room is at a harsh angle.
How it feels doesn’t matter much. The best way to check for issues is to turn off the lights in the room and then put a lamp right up against the wall so you can easily see the imperfections.
On the next coat, skim over the patch while being careful to feather out your edges as you go. Every layer you add should be feathered out larger than the last layer.
Lightly sand again and check your progress with the light. If your skim coats are really thin then it should dry quickly and allow you to do a new coat every 24 hours or so.
I did all my skimming and finishing basically in the dark with one light that i moved around at different angles on the wall I was working on. It’s the only way to get things right.
Your finished coat should be smoother than you think. You can always sand out some imperfections and knock down the lines that are raised but it has to look as good as possible each coat
You need to coat that with a lot more mud and make it smooth otherwise it is always going to look like crap especially after you have painted it, and then it becomes more difficult to fix
You need to sand and add more coats definitely, just like someone else said you need a wider taping knife and o feather out the mud, keep sanding lightly beetween each coat to get perfectly smooth. 120 then 220
You can do a final float in a few hours, then a lite sand.
This is fast.
Get a 10-12" knife and metal pan.
Use All Purpose mud mixed with very small amount of water to smooth it.
Watch a YouTube vid that talks about pressing hard on the outside end of the knife so it feathers to zero thickness.
(Maybe watch 5, the more the better)
You will press hard and drag and hear scraping sound.
Most people thing it's like icing a cake and you get this effect you see here in your photos. Put some muscle into it.
Get it on the wall, then drag it off. Put the " off" mud on the back side of the pan, and get new mud from the side facing you.
Pile up that old mud. You may be able to re wet it later, but for now keep using fresh mud. You do not want to be fighting any bits of contamination.
Again, listen to the sound on the video, you want the same sound. Look at the angle of the knife as it relates to the wall, match that. See how they are holding the knife in the hand, match that.
For noobs you may have to keep your pointer finger on the blade because you may not have the wrist strength. That is fine, we all do it here and there.
Do yourself a favor and go buy a wide taping knife. Like, a 10” or 12”. Use that to feather out farther from the tape line. Then sand gently.

If that feels smooth to you, I think you may have lost feeling in your hands.
If its time sensitive and you care about what it will look like, you should hire a professional.
Needs at least 1-2 more coats
Texture everything lol

You can also thin out the mix a bit for the last coat or two. Press harder towards the middle.

Sand it and vacuum up the dust. Make sure you wear a dust mask and get a shop vac for this. Prime and paint after.
