The Job Guide
Recaulk a tub or shower, crisp and watertight.
The short answerTo recaulk a tub or shower, cut and scrape out all the old caulk, clean the joint (rubbing alcohol works well), and let it dry completely. Tape both sides of the joint, cut the tube tip small, and run one steady bead of 100% silicone. Smooth it with a wet finger, pull the tape while the caulk is wet, and keep water off it for at least 24 hours, or as long as the tube says.
Moldy, cracked caulk lets water behind the tub. New silicone is a cheap, one-evening fix. The secret is complete removal and a dry joint.
