How do i fix small painting errors?

[Nanako]

Earlier tonight, while looking at the freshly dried paint in my kitchen, I noticed a little flaw like this

This isnt the exact one, but it looked similar. A drip of paint that had gone unnoticed, and hardened into a bump on the otherwise relatively smooth surface

Maybe i shoulda just ignored it, but i have an eye for detail, i cant help noticing these things, and i couldnt stand the thought of continuing to notice it over and over for years to come

So i figured i'd sand it off, and then do another lick of paint over the spot. I grabbed my hand sanding pad, with 40 grit fabric on it, and gave it a lil rub, then a paint
This was the result

I think this is worse, i am not happy. Halp

how can i fix this, and also fix the mess that ive caused failing to fix it?

If its on wall paper then it will be difficult to hide the flaw without re papering the area or risking damaging the paper. If that is paint on plaster the whole area doesn't look as smooth and flawless as you would expect, you could try lightly sanding with 120 grit paper

it is paint on plaster, i'm not a fan of wallpaper

wouldn't a higher grit paper just cause this problem more slowly?

also, i've been using a large sanding pad bigger than my fist, is the size of the sanding area the problem perhaps?

I have an electric detail sander with various paper grits, would that be too much?

You've got quite a paint texture on those walls, are you laying off the paint properly?

When sanding down walls, best to use an orbital sander which has a good low speed which you can control easily. 40 grit sandpaper is pretty aggressive for sanding down a paint splat. 80 grit would have been more than adequate, 120 grit preferable.

Sand down the area of the wall where you have sanded the paint off using 120 grit to get the scratches out and smooth down the area, then roller it again using the same paint and sleeve you initially used to paint it. Build up the paint so it matches the rest of the texture of the wall.

I would use a piece of sandpaper folded over a block of wood to give more control. Paint on plaster should be a lot smoother than appears from the pics

What exactly do you mean by "build up" ? Like, should i be trying to use a brush to paint in the depressed areas and let especially thick parts dry that way, or just keep applying coat after coat?

Also the comments about the texture are a bit of a misunderstanding, it is slightly textured because i use a foam roller, but its fine, this is just a really closeup camera shot

Nice

Any 'low' spots can be filled with a fine surface filler.

thank you for the replies guys

I ended up buying some 600 grit pads for my detail sander, smoothing out the area and repainting it, can't tell the difference now, it worked wonderfully!
