To dry is one thing, to cure is another.I’ll check to feel of the paint feels tacky tomorrow. It was over 50 here today and it’s sooooo dry the paint was practically fully dry as I painted. I’m not worried about it. I paint a lot and I have more trouble with humidity than I do cold! The rest (trim and clapboard) is being painted in my garage so it should be fine!
