painting minimum temperatures
I had been working just as fast as possible well living here in the great state of Missouri I missed painting this fall cause the temps dropped. Well I am ready and waiting the warm weather.
This week it is supposed to be 60 - 65 outside temp. I can heat my shop up above that but will need to open the doors to exhaust the air as I am painting. the temp wont stay or be at this outside temp very long. Once complete and aired out I can close shop and fire up the heater again and get it nice and warm. Should I wait till spring or chance it. I have worked very very hard to this point Thanks Dave

Put on another coat of primer and block sand the hours away till spring. Spring in missouri is probably only 3 months from now anyway....just think, in the north its like 5 months!

If fresh (before the volatiles are mostly out) paint gets too cold, it will cloud and look dull forever.
Are you sure you can't build a semi warm ventilation system. I buy a 10x100 piece of plastic and hang it around the car I'm painting and open it up alittle for ventilation. This also works good to create a "booth" of sorts. It'll also keep the temperature from changing too fast. Here's another thought. I always wanted to try taking a 10' long piece of duct work, sticking it under the car (low buck downdraft system) with a fan sucking to the outside. Maybe you could try something that. You MIGHT be OK at 60-65, 65 or up and you're good to go. Just my ideas... |

ditto on 65 degrees, seems to be the minimum recommendation, but it needs to be constant or you'll get less than desirable results... not sure about all paints, but PPG specifies different mix ratios for painting at lower temps... I'd probably play it safe and wait for warmer weather.

I painted this last weekend. The temp was in the upper 50's. I did heat the garage up for about 12 hours prior to painting. I kept it at a constant 75 degrees. I opened the side door about a foot and ran a fan for exhaust. As soon as the cloud was out, I fired the furnace back up. I used PPG DBU base and Concept acrylic urethane clear (70 degree reducer) with no problems. I think it helps to get the cement floor and the rest of the objects in the garage warm. I have a Reznor 40,000 BTU suspended unit heater. It has a sealed combustion chamber but I just don't have the huevos to run it while I'm shooting paint. The paint came out smooth with no runs, orange peel and great depth.

If you can work out the heating issues, painting in Winter has the advantage of few bugs and less dust, especially after rain or when snow is on the ground. Maybe rent a paint booth for a day or two.

Painting in 65 deg shouldn't be a problem if you use apropriate reducers. Granted 65 is not the ideal 70-75 but I have painted in 55 degree weather without any isues.
From my experience with some PPG clear coats is that they'll start to fog on you if you go below 50 and the paint is still wet with temperatures dropping and as we all know that causes condensation. Nice thing about modern refinishing products is that flash time is typically very quick if appropriate reducers are used. Also you can look into using accelerators (additives that promote quicker curing) The other thing to keep in mind if you're painting in cooler temps is respirators collect the moisture from your breath and they'll drip all over flat panels like hoods, roofs and any other big parts that you have to lean over to spray. I've just roll up some tissue paper and put it in the bottom of the respirator (kind of like a diaper and you have to change it out periodically) Best of luck to you,
