Clean the Sink

Use mild soap and water or a specifically formulated porcelain cleaner to remove any dirt or debris from the chipped area. Cleaning a broken sink can be a little more challenging than cleaning a fully functional one, but it is still important to maintain proper hygiene and keep the area clean.

Allow the Compound to Dry

Follow the manufacturer’s instructions for drying time. This can vary depending on the type of repair compound you are using.

Sand the Repaired Area

Once the repair compound has dried completely, use sandpaper to smooth out the surface of the repaired area.

Clean the Sink Again

Use a mild soap and water or a specifically formulated porcelain cleaner to remove any excess compound or dust from the repaired area.


Apply a coat of sealer. If you want to protect the repaired area from future chips or damage, you can apply a coat of sealer to the repaired area. Follow the manufacturer’s instructions for application.

Do porcelain sinks chip easily?

Porcelain sinks are generally known for their durability, but they can still become chipped or damaged over time. Factors that can contribute to the likelihood of a porcelain sink becoming chipped include the thickness of the porcelain, the quality of the sink, and how it is used and cared for.

Sinks made of thinner porcelain are more prone to chipping than those made of thicker porcelain. In addition, sinks that are of lower quality or that are subjected to heavy use or abuse may be more likely to chip than those that are of higher quality and used with care.

To reduce the risk of a porcelain sink becoming chipped, it is important to use a sink mat or cushion to protect the bottom of the sink and to be careful not to drop heavy objects or place sharp objects in the sink. Regular cleaning and maintenance can also help to prolong the life of a porcelain sink and prevent damage.

What should you not put on a porcelain sink?

There are a few things that you should not put in or on a porcelain sink to avoid damaging the surface:

  1. Acidic or abrasive cleaners – These types of cleaners can erode the surface of the porcelain, causing it to become chipped or discoloured.
  2. Sharp or heavy objects – Dropping heavy objects or placing sharp objects in the sink can cause chips or cracks to form.
  3. Hot pots or pans – Porcelain is sensitive to extreme temperature changes and can crack if it is subjected to very hot or cold temperatures.
  4. Metal objects – Porcelain can become scratched or damaged if it comes into contact with metal objects, such as pots and pans.
  5. Harsh or abrasive scrubbers – Using harsh or abrasive scrubbers to clean a porcelain sink can scratch the surface. Instead, use a soft sponge or cloth and a mild, non-abrasive cleaner.

By avoiding these items, you can help to keep your porcelain sink in good condition and avoid damaging the surface.
