Porcelain is an attractive and durable surface for a bathtub. However, like most other materials, even porcelain can chip.

If the chip is in an area which is always dry, such as the outside surface of the tub, a single repair should do the job. But, there’s also a possibility that the damage may need to be repaired repeatedly when the chip is located in the basin of the tub. Keep reading and learn how you can fix the cracked porcelain by yourself.

  • Smooth down the edges of the cracks

Use a fine grit sandpaper to sand down the edges of the crack until they’re absolutely smooth. Any remaining dust can be blown away a straw attachment added separately. Use a microfiber cloth to wipe away any of the remaining dust particles which may have been left behind.

  • Clean using acetone and blow dry

Soak a piece of cotton in acetone. If acetone isn’t easily available to you, it can be substituted with nail polish remover. After you’ve smoothened the edges of the crack, use the soaked cotton ball to wipe down the area gently. Be sure to let it dry completely.

  • Apply the compound in a well-ventilated area

There are compounds available in the market which is applied to the area of the crack after the sanding and wiping are done. However, make sure that you read the instructions very carefully and allow the mixture to sit in an appropriate container.

Use a face mask to protect your face from harmful chemical vapours while applying the compound. A nail paint brush or a regular paint brush with a fine tip can also work. Using a dabbing motion with your hands, apply the compound and allow gravity to work the compound well into the crack. If it’s a large chip or crack, the compound may need to be applied in several layers. Also, ensure that each of the layers has dried off completely before applying another coat of it.

  • Level the surface evenly

Use a flat wooden stick to remove excess compound from the crack and to flatten it out well. Just be careful not to take off too much of the compound as it will still need to be sanded down and smoothened once the compound is completely dry.

  • Sand and smooth the surface

After the compound has had enough time to dry, using fine grit sandpaper, smooth out the area until it completely matches the surface of the porcelain.
