Can I apply new caulk over old caulk?

A durable joint normally requires removal of failed material and preparation that follows the new sealant instructions. Wet or contaminated surfaces can affect adhesion.

Does caulk make a shower waterproof?

No. Sealant is a finish-joint component. The waterproofing assembly behind the tile controls water management.

Why does corner caulk keep splitting?

Movement, joint geometry, preparation, product choice, curing, or an underlying assembly condition may be involved. Recurring failure deserves field review.

Shower Caulk Failure | Austin Tile Assessment

Learn why shower sealant can split, peel, stain, or separate, what to document first, and when an Austin shower needs more than a simple recaulk.

Split, peeling, or separated sealant may involve surface preparation, movement, product selection, joint geometry, cure conditions, maintenance, or water exposure. Recaulking can restore a finish joint only after the surrounding condition is understood. Stop using the shower and investigate promptly if there is active leakage, soft substrate, loose tile, staining outside the enclosure, or damage below.
