I used the cheap wal-mart brand primer for the new ceiling and Zinnser 123 for the old painted ceiling. The put the valspar on top of that. Perfect and no runs or problems.

That's a good point. If there are adhesion problems, no amount of paint will make a difference. Did you wash the ceiling first? Buildup of dust and grease can cause adhesion problems and make you waste paint needlessly. Beyond that, you may well need to prime. Zinnser is good primer, but be careful with it, because it will fuck you up. Use it in a well ventillated area, unless you're into that sort of thing, in which case seal off all ventillation and make sure your will is current.

damn. 4 cans of paint down the drain. I didnt wash the ceiling - it was pretty clean. I'll try taking a pic today. I wanna be sure its adhesion problems because I dont want to waste money on primer and then on paint again. If I do have to start over again though, Im using those color changing paints. White on white is really hard to see

Funny, I will never use Benjamin Moore. I painted all of my house with Valspar Premium paint. Love the paint as it went on perfectly even when I made a few mistakes. Then my wife got pregnant and we wanted to paint the nursery a different color. I went with Benjamin Moore Aura because of the low VOCs. Worst shit ever. It did not go on even, looked like crap, had runs left and right.

Not sure if it matters but I did use primer with the valspar. Maybe that is the problem you are having.

If you believe it is adhesion, before you try primer, go buy a $2 box of TSP and give that a shot.

If the ceiling is flat paint (which is should be) and you have adhesion issues, primer (in general) won't help. The underlying problem would be grime and oil, which primer also won't adhere to*. You have to clean first.

* the exception being the wonderful, albeit more expensive, bonding primers.

i think atomic and marlin are onto something with the primer. I primed the walls and have no issues with applying paint on em.

is primer tintable? can I put a slight grayish tint on it so I can see the white paint when I reapply on top of he primer?
and what kinda primer should I get? Ive used Valspar high hiding primer on pre painted surfaces and drywall primer on bare drywalls. had no problems with those.

yea but there is already paint on the ceiling covering any oil or dirt. Would TSP cut thu the paint to get to the dirt? And how do you apply TSP to ceiling? roll it on?

you have to keep a wet edge. do square/rectangular patches in lines across in a systematic fashion to keep the edges wet and blending.

and yes..primer

or if theres ceiling texture, use a sprayer.

heh, slight oversight on my part. of course there's already paint there! (BTW- TSP is granulated, you add it to water and sponge it on and rinse)

You can tint primer. Grey is definitely the way to. The drawback is that most cans of primer aren't short-filled (since they don't plan on you tinting it), so you won't have much room to add colorant. You'll probably get a light grey, but nothing darker.

Is the currently-applied paint peeling at all?

You have a smooth ceiling with some stipple. Before you go any further, use some sandpaper to knock down the stipple or it will only get worse. The rough sanding will also help your next coat adhere.
