How do I deal with thick paint on wall?

I got tired of the dark green paint in my kitchen, so I painted it a new "butternut" color. I used white primer then 2 coats of latex paint. The color is too much for me now, and I want to go with a neutral color, but am already uncomfortable with the thickness due to all the layers of paint.

I've read different posts, and it sounds like my best option is to sand the walls before painting? Can anyone walk me through the exact type of sandpaper and technique? Specifics and step-by-step advice would be greatly appreciated.

Welcome to the forums!

Generally multiple coats of paint on a wall pose no problem. How long has the paint been on the wall? has it had time to cure?

Usually a scuff sanding with 120-150 grit sandpaper is sufficent. On open walls I like to use a pole sander because it's quicker a power sander is pretty much overkill. It's always a good idea to remove any sanding dust before repainting.

Thanks for the quick reply! I just painted it this past Saturday. "Cure," I imagine means fully dry?

I look at my other walls, which only had one coat of paint, so in comparison, my kitchen wall seems thick. But maybe that's my personal perception. I'm afraid that if I use another primer plus 2 more layers, the walls will be even more gloppy.

Latex paint needs a little time to fully cure.This is beyond just being dry.

If the paint you used has any gloss you might want to scuff sand it once it cures and before you paint over it but you probably don't need to prime it again assuming you use latex over the existing latex.

If all 3 coats of paint/primer were applied this past weekend, I'd be inclined to wait until next weekend to repaint. Sometimes there can be issues if too many coats of paint are applied too close together. It can take latex paint a week or two to cure. The paint may be dry on the surface but still soft underneath.

Generally speaking, primer isn't needed when repainting. The main reasons to use a primer is to seal a new/raw substrate, fix adhesion problems, cover and seal stains and with some colors - help with coverage. I doubt you need to reprime.

It is hard to visually tell the difference between 5 coats of paint and 10 coats on the wall so unless you have areas where the paint was gobbed up on the wall, more coats of paint shouldn't make any difference.
