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????
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.
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.
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.
