re-sanding before re-painting a newly painted wall?
Hi there---
I just repainted a wall 2 days ago. I sanded the old paint, i spackled, I sanded, i primed with Zinsser bulls eye 1-2-3, then i applied 2 coats of a Benjamin Moore pearl-finish acrylic paint.
NOW, i have decided that the shade isn't EXACTLY what I want, and i want to re-do it.
Also, i found a hole that really needed to be addressed with joint compound, so i did that too, and that area will obviously need to be primed and painted.
My question is, do i need to re-sand before applying my new NEW color? and especially because there will be that small spackled area with primer on it, will that area look inconsistent with the rest of the wall if i don't reprime EVERYTHING....?
thanks!---- rita

If you are using the same exact paint you probably don't need to prime beyond the patch.If "pearl" means it has some gloss a scuff sanding is probably a good idea.If the color change is beyond slight priming might help the new paint cover.

it will be the same exact paint, and the color will be VERY VERY similar. pearl does have a little bit of gloss to it, yes... it's a kitchen wall.
sigh, scuff sanding.... more dust!!! :/

There is very little dust associated with scuff sanding. You will probably make more dust sanding the patch getting it ready for primer. I'd also paint over the primer with a little of the previous finish coat - just to make sure the repair won't show.

Good questions.
You don't need to reprime the whole wall - for adhesion. The reason that you don't need to degloss / prime freshly painted latex wall paint between coats, is because the paint is not fully cured and the next coat of latex will melt together to the soft, sticky, un-cured previous coat. Once the paint cures you will need to degloss (or re-prime) before recoating.
As far as the spot showing: In your case I would go ahead and spot prime with the 123 Bullesye, because the rest of the wall has it underneath. Normally, if you spot prime with a stain blocker (like 123 Bullseye), the "spot" will "flash" and look shiny and sometimes whiter. You shouldn't have that problem in your situation.
