I would like to start getting it ready for paint. I will be using all supplies from NAPA and my question is I have a semi-heated garage. Only when I am in there.. It gets to a comfortable work temperature but it is not super warm by all means. Anyway if I have the shop warmed up will I be able to spray my tractor in primer? Thank you in advance for any replies... [Reply]   [No Email]

The paint is going to assume the temperature of the part you're painting, it doesn't care what the air temperature is. It can take a real long time for cast iron to come up to room temperature. If you've got a jet type heater, blast the part directly with heat from that - as long as the air's moving over them, they should come up to temperature quickly. (of course - you'd turn that off before painting) If there's no circulation, it'll take forever for the cast to warm up. At a minimum, just use a house fan to keep the air circulating over the parts.

I have painted in cold weather in a partially heated garage a few times successfully. I get the paint nice and warm in the inner room in my shop. I heat the outer 40x50x17 up to about 60 with a propane salamander, making sure that all of the cast has plenty of time to come up to temp. When I am set to paint I turn off the heat and turn on the fans and the thermal mass of the building and everything in it will hold the temp up plenty long enough. It is doable only if the building and contents will hold enough heat. [Reply]  [No Email]

To keep from having to do this you would have to turn the heat off and only spray about six or eight ounces at a time. You will also have to stick with the specifications on the primer you using. I use Nason Ful-Poxy and the shop temperature needs to remain above fifty degrees until it dries. What you will need to do is determine if you garage will retain heat for a couple of hours with the heat off. [Reply]  [No Email]
