On the job this morning I went to the truck to get paint to paint some stakes. We keep a case of Krylon paint in the truck and it sits outside. Last night it got down to about 20°. The agitator ball would not ding-a-ling and no paint would come out so tried other cans but no go. Finally warmed up a can and it worked fine. The cans of Krylon in my unheated garage were also frozen. Tried several Ace cans and they agitated and worked fine. Apparently Krylon has changed their formula. We work many winter days when the temp. is well below freezing. Cans of paint are carried from the unheated back of the truck and are pretty much exposed to the cold all day so it is no good having to worry about paint freezing.
Usually says on the can the temperature range, also marking paint is usually a dense mix with a quick dry formula. Have had to plan ahead when using that paint when cold for years.

The florescent colors have a different formulation than the non-florescent colors. I use the non florescent colors for markings that need to stay on for longer periods.
This may also have an effect on the freezing temp. It would be worth trying.

Due to local fire regulations, we are not allowed to store cartons of spray paint indoors, so it's kept out in the rear in an unheated bin.
Crews would complain about frozen paint.
Yet, every winter morning we go out to a site, the crew has their paint kept in the back of the van, which of course, is out in the driveway all night........:-S
WATER BASED PAINTS FREEZE ?
Fewer choices on petroleum based paints every year.

WATER BASED PAINTS FREEZE ?
Most of my customers don't want florescent painted objects to remain so I use the water based product.
After a rain it is usually diminished and will disappear quickly. Mow the grass and it is gone.
I have learned to store the paint cans in a closed container (I use a cheap socalled watertight plastic box with a handle from wallyworld) that will hold six cans. Too many accidents with unnecessarily painting things that should not be painted.
At least there are not many 20° days around here.
We just throw a can or two on the floor of the truck under the heater vent on the way to the job. So far (37 yrs.) we've not had one roll under the brake or accelerator pedal and cause an accident. I guess if one did our attorney would sue the manufacturer because there's no warning on the can telling us not to...
That is what I do, then I carry the paint in an inside pocket of the vest. Works fine and I expect it to continue that way. It is digging a hole in ground frozen down to 3 feet that makes me sweat. Done that a few times to set brass caps on a 2" X 30" flanged pipe to grade.

I've blazed and painted large (100+ acre) lots alone on snow shoes in below zero weather keeping cans of paint inside my shirt and changing them out to keep them going. I'd just rather not have to deal with frozen paint in the fall and will stick with something that works as long as it's still available.
