How To Fix A Hole In A Porcelain Sink?

The idea of fixing a hole in a Porcelain sink is to use specialized adhesive to fill it in. You just need to follow the five steps below to recover the flawless shape of your sink.

Step 1: Gather the tools

A porcelain sink kit has everything you need for this task. It often comes with the following:

  • A wood stick
  • Adhesive of a matching color
  • Sandpaper
  • Gloves

This kit costs from $14 to $40, and you can easily get it from a home improvement store. Remember to choose the kit that can match your sink’s color. Also, please note that some sink models require a specific kit.

Step 2: Sand down the hole

Prepare the work area before you start by sanding the rough edges around the hole. Your Porcelain repair kits always have a medium-grit cloth for this step.

Only work around the affected area of the hole. After that, wipe away excess materials using a towel. A blow dryer can also help, but be careful with the dust.

Step 3: Clean the sink

The preparation step also involves cleaning the Porcelain sink. You may see a reinforcing product in your repair kit. However, it only works with direct contact between the Porcelain and the adhesive.

So, to clean your sink, use a mild agent, like warm water and soap. Harsh cleaning solvents may cause damage and leave holes in the sink.

After cleaning the sink, use a blow dryer or a cloth to dry it before jumping to the next step.

Step 4: Apply the adhesive compound

Now, mix the adhesive compound. Your repair kit has two jars, and you need to mix them to form sealing compounds. Each product has specific ingredients, so you must carefully check the instructions to proceed.

Moreover, these sealing compounds may contain harmful chemicals. Thus, avoid touching them with your bare hands. A pair of gloves is helpful in this case.

Next, use the wooden stick in the kit to apply the mixed adhesive to the hole in your Porcelain sink. If the hole is too minor, use a razor to administer it. The razor also helps smooth out the adhesive after applying it.

If you accidentally over-apply the adhesive, stay calm. Then, dip a cotton ball in nail polish remover, and use it to wipe away the extra adhesive.

Step 5: Let it dry

The drying time of the adhesive varies from product to product. So, again, consult the instructions to tell how long your adhesive can firm up. Before that time, do not run cold or hot water in your sink.
