Why is porcelain sink cracking: assess porcelain sink damage

Before diving into the repair process, it’s crucial to understand why porcelain sinks develop cracks in the first place. These cracks can result from various factors, each of which may require a different approach to repair, so it’s important to have an understanding of why they became cracked in the first place.

1. Thermal stress
 
Porcelain sinks are exposed to drastic changes in temperature regularly. When hot water is poured into a cold sink or when a hot pan is placed directly on the sink’s surface, the rapid temperature fluctuations can cause stress on the porcelain. Over time, this stress can lead to cracks and fractures.
 
2. Physical trauma
 
Accidents happen, and porcelain sinks are not immune to them. A heavy object dropped into the sink, or another type of sharp impact can cause visible damage in the form of cracks or chipped edges.

Damage may occur due to external shocks.

3. Wear and tear over the years
 
Years of use can take a toll on your porcelain sink’s surface. Constant exposure to water, cleaning agents, and abrasive scrubbing can wear down the porcelain, making it susceptible to cracks and chips.

Understanding the cause of the damage will help you determine the best approach to repairing your porcelain sink effectively.

Clean and dry the sink

You’ll want to begin by thoroughly cleaning your porcelain sink. Use a scrubber or sponge to remove any grime, dirt, or residue around the damaged area. Then, you will need to rinse the sink with clean water and ensure that it’s completely dry before proceeding

Sand damaged area

Next, carefully sand the damaged area of the sink by using fine-grit sandpaper. Sanding helps create a smooth surface for the epoxy putty to adhere to and removes any loose or jagged edges around the crack or cracks.

Apply epoxy gap filler compound

Follow the instructions on your porcelain sink repair kit for mixing the epoxy putty. Typically, you’ll be required to knead equal parts of the putty until they are thoroughly blended. 

Mix in a certain proportion until completely mixed.

Then apply the epoxy putty to the cracked or chipped area, making sure to press it firmly into the damaged space. Use a putty knife to smooth the putty evenly and remove any excess. Allow the epoxy putty to dry and cure as per the manufacturer’s instructions. It usually takes only a few hours to cure.

Apply porcelain tile touch up paint

Once the epoxy putty has fully cured, it’s time to touch up the repair with porcelain tile touch-up paint. This paint is specially formulated to match the color and finish of porcelain sinks.
 
Apply the touch-up paint carefully to the repaired area, ensuring that it blends seamlessly with the surrounding surface. Multiple thin coats may be necessary to achieve the desired finish.
 
Finally, allow the touch-up paint to dry completely between coats, following the manufacturer’s recommendations.

Consider optional vanity top sink replacement

In some cases, the damage to your porcelain sink may be extensive, making repair less practical. If the cracks are severe or the sink has numerous chips and fractures, you may want to consider replacing the entire sink. This can be a more expensive and time-consuming option, but it ensures a completely new and well-performing sink surface. It will also save you time and money on a repair project that would only last temporarily anyway.

Replacing the sink may be another option rather than repairing it.
