You can tell caulk has failed when it becomes loose, cracks, pulls away from the surface, or shows signs of mold and mildew[2]. To remove it, use a utility or putty knife to score and scrape away the old material, potentially using a caulk remover gel to soften stubborn residue[1][2]. Once clean and dry, apply a fresh bead of silicone or kitchen and bath caulk at a 45-degree angle, smoothing it with a tool or your finger for a watertight seal[1][5].
Quick Checklist:
* Curing: Wait at least 24 hours or follow the specific label instructions before using the tub[1].
* Common Mistakes: Failing to remove all old caulk, leaving moisture behind, or skipping painter's tape often leads to poor adhesion, peeling, or recurring mold[1][5].
