Pro tip: Caulk drying times on tubes are basically a suggestion from a parallel universe
I was sealing up baseboards in my 1950s bungalow last Saturday. The tube said 'paintable in 30 minutes,' so I waited an hour to be safe. When I touched the line, it was still tacky underneath. I looked it up on a building science forum and found out that drying times are tested at 75 degrees with low humidity, totally controlled conditions. My basement is 62 degrees and damp, so the real dry time is more like 4 to 6 hours. So how do you guys handle the gap between what the label says and what your actual house conditions give you? Do you double the time, or just trust the finger test?
