You can maintain a scratch-free ceramic bathroom sink with little time and effort by following the steps listed below.
Step 1 - Obtain a Porcelain Repair Kit
Purchase an epoxy-porcelain repair kit. When purchasing your kit, be sure to find a color that is a lighter shade than your sink. Mix components in the kit by following the manufacturer’s directions.
Step 2 - Clean Scratches and Nicks
Remove all dust or dirt in the scratches or nicks of your porcelain by using a cotton ball and rubbing alcohol. Use a microfiber cloth and wipe each of the scratches until they are completely dry.
Step 3 - Apply the Epoxy
Use the end of a matchstick or a toothpick, dip it into the repair solution provided in your kit, and carefully dab the solution into the nicks or scratches. Use the tip of a dried marker that has been washed to fill larger cracks. Be sure the color in the marker tip has been removed.
Step 4 - Apply Additional Coats
After applying your epoxy, allow at least an hour before you apply a required second coat to each chip or scratch. Continue this process until all scratches and holes have been repaired.
