I need to shoot some primer and 2K poly and it's starting to get a little chilly.
Not the whole, just the engine compartment and interior.
I am using an HVLP setup.

What is the lowest (coldest) ambient temperature I can shoot in?

I can not heat up my work space so what other steps can I take to help with cold weather painting?

Thanks

 

I would not paint if it is under 50-55 degrees, using a fast reducer will help with lower temps.

 

I'll add that is temp of the metal, not air temp. I do paint a bit in the winter, but it takes a long time to heat up the metal after getting the garage warm. I'll start heating the garage in the morning and paint late afternoon. With no heat in your garage, better wait till warmer weather.

 

Ditto. I try not to shoot under 60 degrees and actually prefer it to be 70 or so.

 

i agree 70 is just about right...higher temps and a slower reducer helps the paint to flow out... less orange peel.
