Spray painting in cold

[gsi racer]

Is there any advice on spraying in the cold weather. Tried spraying last weekend, only did one coat and the paint run. Bought a faster hardener this time, any thing else I can do? Spraying in closed garage with extractor fan, 2k paint. Also tried heating the garage with heaters but need to put it of when spraying, scared for the big bang.

If the paints running your too close. That's nothing to do with heat or lack of.

Put the heater on before you paint, then after you have.

yup what he said, but can also be too thin. also it might be worth getting an oil filled heater, and placing it in the car to keep the car warm while your other heating is off.

I'm always thinking it's gonna go bang, but I have a log burner in my garage, and I've had it running while spraying, I've even offloaded the gun into it when i was cleaning it out, and the direct vapour didnt ignite. I've even sprayed with celly with my burner going, and had no adverse explosions.

Your better safe than sorry though

Could be putting too much on. What size nozzle you got?

Too thin, always adjust your mixture to suit your environment (as much as practicable), although spraying in the cold is always pissing into the wind.

A fast activator will just help the paint to cure properly due to the lack of heat, it won't do anything to help running I'm afraid.

1.4mm nozzle. Did spray a thin layer,could still see the primer. Can heat the garage before hand but the moment I put the heaters off, the heat will be gone before the second coat.

You don't want loads of paint on in one go anyhow, just build it up gradually if need be.

if i need to paint in cold weather, I warm the panel that I am painting with a hair dryer

Difficult to heat the complete car with a hair dryer.

put the paint into a mixing vessel then put into a bucket with warm to hot water in warms it up and then apply
