Looking to see if anyone has any prior experience with interior painting a caboose in the cold months? Could I continue my work if I keep the oil stove cooking and the overall temp up inside? Car is stored outdoors. Paint is S-W Pro Cryl B66 W 1310 Primer. Top Coat will be S-W Waterbased Alkyd Urethane B53 W 2251.

Thanks,
Mike

Do not use the oil stove. If you do you could set the solvent vapors on fire. If you want to keep painting, get an electric heater that will keep the interior temperature above the minimum temperatures listed in the instructions that came with the paint or from paint company customer service representative. The heat will have to continue until the paint is tack free.

I’d wait until the temperature stays above 50 degrees and you can open doors and use a fan for ventilation. Temperature and humidity play a big role in curing. You didn’t say if you were going to spray or brush/roll. I’d definitely suit up with a respirator if you’re spraying in such close quarters. Read the SDS sheet available online for personal hazards. The primer doesn’t look very evil but the top coat might have potential to do some damage. The good news is that this stuff doesn’t appear anywhere near as wicked as catalyzed urethane.

I’ve been rolling with good results. Very happy with how it’s covered thus far. The primer shows being able to apply down to 40* but I’ve been staying higher than that. The electric heat is a good point. I’ll experiment with keeping heat in and venting prior to any further paint. Just hate to lose several month of work sessions, due to weather.

Does it matter if the walls might be a lot colder than the interior air temperature? It might take some time for the walls to warm up after the air temperature is warm enough to paint.

Both the substrate and the air temperatures need to be at least the recommended minimum application temperature for a proper cure.

I’ve been shooting the wall temperature with a temp gun. I would plan to do the same if attempting to paint further.
