I just sprayed rustoleum primer on something. The object was first cleaned by acetone and dry. The primer went on fine.
15 minutes later, I tried putting rustoleum red on it. In quite a few areas, it's just beading up.WTH. the primer should have setup the color coat. The object was clean to begin with, then cleaned with acetone, dry ... And now the finish coat won't stick to the primer????
Rustoleum makes a bunch of different products. Are you sure you used a compatible primer and paint?
Yep, I'm sure. These are true blue rustoleum. Just got off the phone with them, they had no clue other than saying contamination. But that's not an issue ... Acetone cleaned. Primer went on.. I use a turntable, so I didn't touch it at all. Then the paint went on 15 minutes later and beaded up.
I tried to find out how to clean out these cans. They introduced those spray from any angle cans 2 or so years ago. I have had disastorous results with them. They clog up.. you are not cleaning the tube out when you turn it over and spray. They told me to just stick the sprayer in MS and it will clean that.. I told them that's not the problem, I am doing that.. The problem is that once you start to use a can, you may not be able to finish the can, as the tube inside is now clogged. I have a few cans like that... they never heard of that problem either.
I am curious if anyone else is experiencing this on these new spray from any angle cans.
So far 3 cans have failed. Not nozzles.
Does the primer give a re-coat time? Some paints are OK for a short time, but if you miss it, wait 24 hours. Others want you to wait at any time. You can get some funky reactions.
What did it say on the primer can about how soon you could top coat? Fifteen minutes seems too quick to me.

Be my guess...15 min isn't long at all, even for a light spray coat and especially if did a couple coats. I'd lay odds the spots that beaded were slightly heavier and while might appear dry on surface weren't fully underneath. They recommend 15-30 min @70F/50%RH so that's a possible effect, too.
I've not had the described problems w/ Rustoleum's cans--I've used quite a number of them to less than full first time and then finished them off later...sometimes many months later.
You must recoat within the hour. after that after 48 hours.
What happens is the paint gasses off and causes bubbles in the upper coats.
What is the weather or temp like. When you cleaned with acetone did the object cool enough to cause condensation?
It's a warm day here. Shot it in the basement where it is cooler. The acetone cleaning was also done about 5-10 before priming as I had to find the good nozzles for the primer.
So it wasn't condensation, and any problem should have shown up on the primer. But there was a nice coating. I apply primer fairly dry, not really wet. My color coats start off with a dusting coat and I add and come closer after I see a good bond, which I did not see , I saw the beading even during dusting in some areas.
I'll let this dry and gas off for 48 hours, sand it out, and try again. This time using sikkens m600 a paint prep cleaner. The acetone is something I do for bare metal. The sikkens generally on previously painted , but sometimes on bare metal too.
