I have some brackets and parts to paint. I noticed that the Rustoleum 7777 can shows that 90* is temp limit for optimum conditions. Well, lately here in Arizona it doesn't get below 90* till "O-Dark-Early" in the morning. But then it is still 100* in my garage. (No A/C obviously!) I really don't want to have to get up in the middle of the night just to paint a couple brackets. I don't have spray equipment right now so mixing for high temp isn't an option.

So my question: How high can the temperature be while painting with a rattle can and still get good results?

Take 'em over to the bank and lay 'em on the counter there to get r done!

Why not shoot a test w/ your paint and see what happens? I kinda doubt that the temp is that critical, really.
You could refrigerate the paint and the parts, then paint as they warm up to a reasonable temp - just thinking out loud there.

IMO I dont think you'll have too much of a problem spraying it at normal temp for you.

I'm just thinking out loud here too, but if you refrigerated the parts, would any condensation form that could mess up the paint?

You should not have any problems. Like they suggested get a old bracket and paint it for a test.

For small parts the temp is not that critical for aerosol. A nice finish will be difficult or impossible on larger parts. Aerosol's solvents are for optimum conditions. That's why they are not offered in temperature ranges.

I agree

I am not familiar with the #7777 product, but I do not have any problems with rattle can Rustoleum. I spray it on and put the part on an old cookie sheet and then bake it in the oven (yep, I am single) at 230 deg F. Leave it in for an hour. The result will be a tougher paint than air-dried. And it will resist solvents much better.

If you want a good job wait until about the 3rd week of October. Rattle can paint does go on different in the heat.

Hmm i spray rust-oleum in any temp or humidity. I never had any lift or malformed paint. It changes rapidly in weather conditions for Maryland.

Only problem i ever had with it is, the oil they use to stop rust, will become a problem when using Nason degreaser and removers. It tends to turn the paint back into a paste.

Not Rustoleum brand in particular. Rattle can paint will have a better finish if it dries slower. The temps in AZ don't start dropping until October. There is also lots of dust in the air. If it's 90 degrees then chances are the metal is also 90 degrees unless it's out in the sun and then you will have real problems trying to paint.

Thank's for the replies!

We had a cool & humid day on Saturday (after rain it was only 88* with 78% humidy.) I painted a few parts and they seem to have been covered well. The semi gloss looks ok, but the high gloss finish is cloudy. We'll see how they hold up.

I brought up this temperature issue topic because...The last time I rattle-can painted was about 4 years ago. The mid July temp was over 100* but the Mrs insisted that the kid's wagon be painted that day. It looked great, but within about 6 months the paint flaked and peeled like bad sunburn. (And, yes, the surface was prepped & cleaned meticulously and painted in the shade.) So, when re-painted it the following May at about 85* the paint flowed out well, dried slowly, and still looks awesome today.


Thank's Jay
