Blotchy paint after using Kilz to spot-prime and other similar issues
 
2 Attachment(s)
So we recently purchased a house that was in dire need of paint EVERYWHERE!

Started out fixing nail pops in the drywall all over the place, touching up walls with spackle, etc. There were a few minor stains in one ceiling, so I bought some Kilz2 figured that would cover the spots, and would work for a good general primer. Wrong!

Every spot we spackled we spot primed with Kilz. Then put some good MAB interior paint over top of that. All the spots that had Kilz dried completely different. Even on the ceilings (flat paint) look horrible when the sunlight hits them. Looks like high and low spots, or eggshell/flat/gloss. See the attached photo - not the best photo, but shows the blotchiness the best. Check out the far wall and the ceiling.

So I have a few issues. Two rooms are completely done. Is there anything I can do to resolve these spots at this point? I gave one room a second top-coat to see if it would help - no difference.

Second problem - one room has already been spot primed with Kilz. Should I completely "prime" the walls and ceiling with a complete coat of Kilz? Or get a regular primer?

Any suggestions are really appreciated!

Blotchy paint after Kilz
 
I just finished my 4th room...I used Kilz primer in 3 rooms with no problem; however after reading a lot of these threads :) I changed to Zinsser Bullseye 123 and it is a much better latex primer. The original Kilz is good, but not the Latex.

Then again, possible the repaired areas were sanded smoother than the actual drywall which can have a very slight orange-peel effect.

Yeh, after reading, NOW I hear Kilz2 is no good.

Anyway, yes - those spots were sanded. But what I'm seeing isn't the smoothness from sanding but the larger area I hit with the Kilz.

I'd prime the entire room then paint, but let one of the pros on here advise you. They have guided me very well.

You really need to prime entire wall( NOT with Kilz). Spot priming is ok for very small touch up but for the most part if you get into any skimming then you really need to prime the whole wall to get an even finish at the end. Use Zinsser primers or something similar, avoid Kilz, unless it is the original oil, then be prepared to go the full respirator route, the stuff wile really do damage to the brain cells. :yes:Trust me on that.

So any ideas how I resolve what I've already done?

Oh no....you mean I need to wear a respirator while using primer???? I didn't and I've already done four rooms

If the stains are water stains, you will NEVER seal them up with a water-base primer, even one that doesn't suck eggs like Kilz2. Water stains need to be sealed with oil-base primer. The Kilz folks even package the oil-base Kilz in an upshooting spray can for precisely this purpose.

The reason your sheen looks different on your spot-primes is the fact that brushed-on primer wiped out the roller stipple from previous coats of paint.

To fix:
1) Spot-prime the water stains (I'm assuming that's what they are) with oil-base primer. Original Kilz will be fine. (It's the only Kilz product worth the can its packed in.)
2) Use a paint roller to roll on a nice, thick, water-base primer on the spots where your texture is all messed up. (I use SW PrepRite Pro Block Latex)
3) Topcoat the whole ceiling with two coats of rolled-on mid-grade flat.

Oh, and no, you don't need a respirator for water-base primer.
