Cold Weather Painting

While I rarely use spaycans, for large area prime coats only, I find them quite adaptable to a temperature range. I do ensure the can is warm enough to spray well and lay down a smooth coat, the can only needs to be a comfortable room temp.

My garage gets very cold, but my spray booth area is easily heated to 60+ with a small conical space heater from Costco, it's surprising how effective it can be. 

I would avoid heating the can close to a heat source, or placing in hot water, that has the potential to create a can rupture. I have heard of that happening.

I also paint in the garage and live in Maryland.  I purchased a space heater for the garage, roughly 300 sq feet,  and found it works pretty good.  Can't recall the brand but it works on electricity and I purchased at Lowe's for around $100.  It has a built in temp  gauge and when it reaches 60 degrees Fahrenheit I shoot paint.   It does take several hours to reach 60 if it's in the 30 degree range outside.  

Thanks for the info guys! Seems the consensus is I need to invest in a heater for the garage. Thanks Again

I do but i have to be more thoughtful especially if useing acrylics. The winters here can be cold and damp and that can slow drying, somthing i have notice dthis year useing MiG paints. I tend to try and paint on a morning, so that tends to mean weekends, that way i am nopt leaving fresh paint over night. If need be, i will bring the model in to the house to help it dry.

I have never had any issues with enamels and thats what i tend to use most.

Be aware that rattle cans cool rapidly as you use them.  I was using a Propel can for my first airbrush, before I bought a compressor.  I had the bright idea of putting the can in a bowl of warm water.  I would shake the can every minute or two.  At one point I picked up the can and the bowl came with it!  The water had frozen.  That was when I realized that I really needed to buy a compressor (ambient temp in shop was normal room temp).
