Bathtub Resurfacing: How to Fix Chips and Restore Shine 2026

Does a chipped bathtub mean you need a full bathroom renovation? Not necessarily. You can repair the damaged surface with glossy, long-lasting products. Whether your tub is steel or cast iron enamel, impacts can cause unsightly black spots, and harsh cleaners can dull the finish. Don't dwell on past mistakes—fix them. Specialized coatings create a hard, uniform, high-gloss layer over worn enamel.

Proper surface preparation is crucial for adhesion. For small repairs or full recoating, remove soap scum and dirt with an acidic cleaner, then roughen the enamel with sandpaper.

Small Chip Repair

For minor chips, polyester filler can fill deep scratches. For larger areas with dull but level surfaces, use a two-part epoxy paint kit for a tough, glossy finish.

Step-by-Step Chip Repair

1. Clean the tub with an acidic solution, then sand the chipped area to remove impurities.
2. Mix the two-part polyester ceramic filler (resin and hardener). Prepare only a small amount as it hardens quickly.
3. Apply the filler to the chip with a small spatula. Always wear gloves.
4. Let the epoxy harden and dry, then sand the area by hand or with an orbital sander.
5. Use fine-grit sandpaper to level the filler perfectly with the surrounding surface.
6. To restore the original white color and gloss, apply a final coat of high-gloss enamel paint from our home improvement collection.

Full Bathtub Resurfacing

If your tub is uniformly dull or has multiple chips, a complete refinish is more effective. This involves cleaning, etching, and applying a new epoxy coating. For a seamless look, also consider updating your bathroom vanity to match the refreshed tub.

Essential Tools and Materials

• Acidic cleaner (e.g., TSP substitute)
• Sandpaper (coarse and fine grit)
