Dormant primers

[chevy_power427]

I was wondering about dormant primers, whether it's epoxy or 2K. Will the activators kick in when the temperature goes back up, or once they become dormant, it's over.

I've read that Epoxy will kick back in, can't tell you on the 2K.

They will cure once the temp increases but it is a very bad idea to apply any type of product with the idea that if the temp drops it'll be ok whe the temps come back up.

Iso type products will cure but could be other damages if gets cold to fast after spraying.

Epoxies are different and will finish kicking if it had good temps for first 24 hours after spraying, cut the good temps after spraying and could cause it to never fully cure, rare but does happen.

What could be a good suggestion to keep the paint booth warmer at night? An electrical heater after the fumes are evacuated?

That's what I use, a 5000W 220V electric heater like this one:

Funny thing, I passed at the hardware store quickly after work, was actually looking at the same exact thing. But there was no suggested room dimensions on the box.

They tend not to last too long without some mods. Mine is a bit hot rodded out and we use an additional small fan behind it to keep it from overheating. Definitely a kludged together deal, but I actually don't know how we did without it when it's in the teens or lower outside.
