Doesn't the can say you're supposed to have the surface above 55
degrees? Will the wall surface be 55 even if the air has made it to 70?
I'd expect the wall to still be cold from the overnight. I wouldn't risk
it since redoing it would be a royal pain. That "Wintery Mix" listed on
the NWS forecast for Thursday doesn't look paint friendly.

The wall faces east and will be plenty warm by the time I was ready to
shoot, but I agree, it might seriously be effected by Thursday night.
I'll just wait, "if you don't like the weather here wait 5 minutes."
