Once the area is fully dry, it’s time to repair the seams and joints to restore a watertight seal and protect the surfaces from future moisture intrusion.

Steps to regrout and recaulk:

1. Mix or prepare grout according to manufacturer instructions if you’re using powdered products. For small areas, pre-mixed mold-resistant grout is convenient and effective.
2. Apply grout carefully into joints using a grout float or small tool, pressing firmly to fill gaps completely.
3. Wipe away excess grout with a damp sponge before it dries on the tile surface.
4. Allow grout to cure fully according to the product instructions — this can vary from 24 to 72 hours.
5. Once grout has cured, apply mold-resistant caulk along seams where the tile meets tubs, shower pans, walls, or corners. Smooth the caulk line with a wet fingertip or caulk-smoothing tool.
6. Allow caulk to cure completely before using the shower or bathtub again.

Choosing high-quality, mold-resistant products makes a real difference. Look for grout and caulk labeled as “mold and mildew resistant” or “designed for wet areas.”

Taking your time during this step ensures that your repair will be long-lasting and resistant to future water damage or microbial growth.
