Thanks to the advent of technology, by using the right porcelain repair kit, you can fix broken sink without replacing it or harming the porcelain finish.
How to Repair a Hole in a Porcelain Sink:
First, ensure you assemble the following items;
- Porcelain repair kit
- Alkyd paint ( if no matching porcelain repair kit)
- Medium-grit emery cloth
- Lint-free cloth
- Water Gentle soap
- Blow drier
- Work glove
- Single-edged razor blade
- Cotton swab
- Fingernail polish
Step 1: Look for a Porcelain Repair Kit Matching Your Sink
Any porcelain repair kit won’t do. You must consider the color of your sink and choose the package that comes with such a tone. If you can’t find the color of your tub, try mixing the repair compound with alkyd paint. To test whether you’ve gotten the right color, apply the mixture in a tiny area of your sink where no one can see. Keep mixing the kit content with alkyd paint until you achieve the color of your sink.
Step 2: Sanding the Hole
The hole in the sink consists of uneven edges and rust. Use a medium-grit emery cloth to sand the entire hole until smooth. Ensure that you stick sanding the hole area only to avoid interfering with the unaffected area. After sanding, wipe off dust, porcelain pieces, or any other dirt within and around the hole.
Step 3: Clean the Sanded Hole and its Surroundings
Dip a lint-free cloth in a mixture of water and gentle soap, then use it to clean the sanded hole and its surroundings. Look for any dirt, debris, dust, or anything else that could prevent proper adhering of the repair compound and remove them. Then allow the cleaned area to dry. A blow dryer may dry it faster than leaving it the water to evaporate.
Step 4: Mix the Repair Compound
First, put on some gloves to protect your hands. Then mix the repair compound following the manufacturer’s instructions. If poorly mixed, the mixture may not work, and your sink will look awful.
Step 5: Apply the Repair Compound
After the repair compound is ready, take the single-edged razor blade and apply the mixture into the hole. Keep applying layers of the repair compound until it is at par with the sink’s surface. Then use the same razor to smoothen the patch. When ready, leave it to dry.
Step 6: Get Rid of the Excess Repair Compound
Using a cotton wool swab dipped in a fingernail polish remover, rub the patch’s edges to remove any unwanted repair compound. Then leave it for a while to dry. Voila! Your porcelain sink repair has come to an end, and it’s free to use.

While the drill is at low speed, place it on the marked location, and apply medium pressure to start drilling. Ensure the drill is steady to avoid straying and scratching your sink. High pressure and drill speed may also contribute to scratching your porcelain sink while drilling.

After drilling the hole, peel off the masking tape from the hole’s sides. Then allow the tool to cool off before attempting to remove it. Then let it dry.
As indicated above, it is better to protect your porcelain sink than having to go through the process of repairing it.
