Porcelain sinks are a beautiful, timeless addition to many kitchens and bathrooms. However, porcelain sinks are unfortunately prone to cracks and holes. Flaws in the porcelain coating can expose the metal hidden beneath, leaving it open to rust and corrosion. Even just a small crack or chip in the sink can lead to a hole, marring the sink’s flawless looks.
Luckily, small holes in porcelain sinks are easily repairable. Bonus: you can buy a porcelain repair kit with the main components you need to fix the issue. Having the repair kit is one thing; knowing how to do it is another. We’re here to help with that part.
Can You Fix A Hole In A Porcelain Sink?
Yep, you can quickly fix a hole in a porcelain sink. Of course, there are restrictions. For instance, if somehow the sink ends up with a hole drilled all the way through the sink, metal and all, you’re going to have a rough time trying to fix it. If that’s the case, you may be better off replacing the sink. Also, we’re not really sure how that would happen, save for intentionally drilling a hole through the sink.
Or, if you’re dealing with a large hole in the sink, you might have a tough time with the repair as well. If it is a big hole, you might consider replacing the sink. However, if you’re feeling confident, you can try to fix it with a repair kit.
So, for the sake of this article, we’re going to assume there’s a small hole in the sink that exposes the metal. Once you can see the metal in your porcelain sink, you need to quickly take care of the issue, as rust and corrosion will happily take over if you let it.
How To Fix A Hole In A Porcelain Sink
We’ll talk about each step in-depth, so you’re confident in your abilities to repair the sink (hopefully). So, without further ado, let’s get started.
Here’s what you’ll need:
- Porcelain repair kit
- Fine grit sandpaper
- Soft cloth
- Ceramic tile and tongue depressor (if necessary)
- Respirator mask (if applicable)
- Small paintbrush (if preferred)
- Straight edge
- Cotton swab
Yes, we know there are a few ‘maybes’ in the list of necessary (maybe) items. We’ll get into that later, we promise. Also, when you choose a porcelain repair kit, choose one that matches your sink (as in color, texture, and gloss/matte).
Prep The Surface
Start by preparing the surface of the sink in and around the hole. Before you apply the compound, you need to properly prepare the area so it will adhere to the sink properly.
To prepare the surface, make sure the area is completely smooth, dry, and dust/particle free. Basically, if it’s not clean, clean it. Use fine-grit sandpaper to smoothen rough spots as necessary. Since you’ll create fine dust as you sand, wipe it away with a soft cloth.
Using a soft cloth soaked in acetone, wipe the surrounding area. This helps ensure the area is clean. Alternatively, you could use soap and water if you don’t have acetone on hand. Allow the area to completely dry before you start mixing and applying compounds. If you don’t, the repair might not adhere properly.
Mix The Repair Compound
Some porcelain repair kits require you to mix the compound. The kit should come with specific instructions and safety guidelines, so be sure to follow them. Sometimes, the kit doesn’t come with a container for mixing the compound.

If it doesn’t, this is where the random ceramic tile and tongue depressor (or craft stick, just something to mix it with) comes in. Using a clean ceramic tile and sterile tongue depressor (or unused craft stick) helps avoid contamination. Depending on the kit you choose, you might have to wait a few minutes to allow the compound to sit before you proceed.
Wear a respirator while you mix the compound. Complete the process in a well-ventilated area to protect yourself from the fumes.
Begin The Repair
Once you’re ready, apply the compound. Most kits come with an applicator, but you can use a small paintbrush if that is your preference. Apply the mixture in layers, allowing it to seep into the hole. Let each layer dry before starting the next. After you fill the hole with the repair compound, allow it to dry.
Once you’re done, use a straight edge to remove excess and create a flat surface. If necessary, use fine-grit sandpaper to create a smooth, seamless surface. Acetone can help remove rough spots around the edge of the hole. If necessary, soak a cotton swab with acetone and wipe the rough patches.
After the repair is dry and smooth, the last step is to paint. While some repairs don’t require paint (minimal cracks or tiny holes), you might have to paint. Since you chose a repair kit that matches your sink color and gloss (or matte), this part is easy.
Simply paint over the repair to create a nice, seamless transition. Allow it to dry completely. And just like that: tada, you’re finished! What hole in the bathroom sink?
