how long should you wait to use a shower after caulking?
Experts such as NaturalHandyman.com recommend allowing fresh silicone caulk to dry overnight, at minimum. Allowing caulk to dry for 24 hours before using the shower will ensure that the caulk is cured and 100 percent waterproof. Even fast drying products should be given 3 to 12 hours to cure before using the shower.
