Heating garage for late fall/ winter painting... ideas?????

[Sodaman101]

OK since I had NO time to paint diddley this summer, winter is my painting time. So I have a garage with 15' ceilings( yea kinda high) and 3 car,IM thinking take some clear plastic( or buy one of those 100.00 cheap " portable garages" and put that in the garage to paint in and make it my " booth". The garage is insulated and I plan on insulating the doors too with rigid foam. So for heat I'm thinking Heat the garage up for 15-20 min with a propane heater, then paint, then ventilate a lot( open the garage doors for a few min) then close the doors and reheat the garage to cure. Prob crack them slightly while Im heating too for ventilation. Does anyone have any other thoughts on this or some ideas of how they do it without say getting another furnace and piping it into the garage with the furnace being outside....... cant do that where Im at. Ambient air temps will be around 30-45 degrees( Now till end of Dec) during the times I'm planning on painting.

Maybe an electric basewall unit that could be switched on and off.
Watch out for flames and such while painting though!

keeping the garage warm will be hard because as soon as you open any doors it will suck the heat out.  Your best bet is what you previously mentioned. Preheat the garage and as soon as the fumes clear turn in a heat source but still keep the garage ventilated. be sure to try to paint on the warmest day possible and use "fast" reducer. It will cure faster. I have a wood pellet stove in my shop and it really knocks the chill out of the shop for winter working!

Depends on what you want or how much you to spend. You can get a garage unit heater that are made for residential aplications. They usually range from 30,000 to 75,000 BTU's and cost between $400.00 t0 $800.00. They are a vent heater and you will have to gas pipe it in, so you don't have to worry about carbon monoxide or flames ignited from paint fumes to easily either, and the thermostat has a on-off switch.

What I do is, I have a ventless heater.  That I turn on and bring the garage up to the temperature that i want to paint at and then I shut off the heater paint and then I put a window fan in the window to help pull the fumes out.  After painting I kick the heater back on,  so far I have not blown myself into the next block...
