You can skip this if the damage is very minor, such as a hairline crack that doesn’t have sharp edges.
This will ensure a clean surface for the chip and crack filler to adhere to and form a strong bond.
Don’t ever apply chip repair epoxy to a wet surface or it will not cure correctly.
Porcelain and ceramic chip repair kits come with 2 vials containing liquids that you mix together to create the epoxy filler, as well as a brush you can use to mix and apply the product. You can buy these repair kits at a home improvement center, hardware store, or online.
Read the instructions on the packaging and defer to the manufacturer’s instructions for any specific directions about how to mix the epoxy.
Again, defer to the manufacturer’s instructions for the specific repair product you purchased for directions about exactly how long to wait before applying the epoxy.
If you apply too much epoxy and get it on the area around the crack, wipe away the excess with a wet paper towel.
Don’t worry about making the chip level with the sink with the first layer of epoxy. You can keep applying layers until you get it just right.
You could write a warning sign and tape it over the sink to ensure nobody uses it while the epoxy dries if this is a concern.
Most minor cracks and chips only need 2 layers of epoxy to fill them in. However, if you are repairing a deeper gouge, you can apply more coats as necessary.
After you level out the repaired area, you can moisten your sandpaper or get the area wet and finish sanding it to shine it up and help blend it in with the rest of the surface.
