I re-caulked my shower on Saturday afternoon, using GE Silicone II Kitchen & Bath Caulk. I left it alone until Monday morning, when I showered in it. I assumed it had plenty of time to cure so did not check before using the shower. When I used a squeegee to clean water off the walls of the shower, I hit a corner and discovered the caulk was still as soft as when I had applied it over 36 hours earlier. I could wipe it away with my finger.
What would cause my caulk to not cure?
- Humidity is about 100% right now. I live close enough to Hurricane Harvey to get lots of rain.
- The silicone caulk tube says to use by 2014. Does this caulk really expire?
- I smoothed the caulk application using my finger dippped in warm water, based on a YouTube video I watched to give me confidence. Was this a bad idea?
