Is it OK to surface prime in 100+ degree heat??

[1BADRS]

I have some extra time to work on the car, but I do not have a air conditioned garage or garage at all for that matter, nor access to one. SUX. I want to get out there and do some surface primeing
but I do not see the heat letting up for weeks or months.
I do not plan to actually spray any of the base coat on untill about November where the Texas heat will not be quite as bad.
I looked on the can for instructions but does not specify temperatures.
I know it can be "Physically" done, but could there be adverse problems later down the road?
I plan on block sanding many times and reprimeing before final top coats.
Thanks!!

Can you set up some sort of interem booth? You can make it out of plastic sheeting.

Not really. I do not really have the materials. However a neighbor is going to give me a tarp frame and cover that should cover the width of half the driveway for now. Just do not have it set up yet.
I guess bout All I can do is wait till late in the evening and try to do work then, and try to get the car (metal) as cooled off as possible prior to spraying. The only thing about that is, as soon as I cool the car off with anything, it will heat right back up very quickly if the sun is still up. About all I can do is wait for sundown and do the best that I can and hope it turns out.
Thanks for the post.

You have the right idea - wait until late evening or early morning, and spray under the tarp. You should be okay.

I have found on really hot (especially windy days) you should hold the paint gun a little closer to the car with a little lighter spray pattern. This prevents too much of the solvent from flashing off before the paint hits the car.

You can also put a little more reducer in your paint so it takes a little longer to flash off.

Between these two i think you will be able to get it done. Practice on some scrap metal and see how well it works. As long as you are able to lay down the paint and it flashes off without running you can paint in very high heat with no ill effects. Practice on scrap is key.

Good luck!

All is well.

Use a slower reducer.. by that I mean one that is suited for the temperature your spraying. Your paint dealer will know what your talking about just ask him.

I'm spraying in the same heat a few miles away. I have been going behind my garage after the sun is low enough to shade the whole area. So far no issues.

No! If you are referring to the room ambient temp that you're will be priming the parts in.

Yes you can if your car/parts are in an enclosure where the ambient temp is much lower than the 100+ degrees. I won't spray anything if the ambient temp is higher than 90 degrees. Nothing sprays very well for me at or around this temp. You will also compromise the product by "cocktailing" or mixing too much reducer with the product so it won't coagulate in the gun. Best to wait for the very early morning when temps are lower.

You can build a portable booth which to confine the overspray.
