What You'll Need

Piece of cardboard
Porcelain enamel
Paintbrush or sponge


A toilet tank lid seems to take a beating during everyday use, and chips will most often appear around the edges. Of course it is possible to simply replace the toilet lid, but it is an easy process to repair the chip, so there is no need to go to the expense or trouble of replacing it. A few simple tools and materials can make even the worst chip disappear, once again giving the toilet a clean, new look. 

Step 1: Prepare the Area

Begin this process by cleaning the toilet lid thoroughly. Concentrate mostly on the chip, and the area surrounding the chip. Use a basic bathroom cleaner and a clean rag, scrub the entire area, and then hand dry with paper towels. 

Using fine sandpaper work over the area where the chip is. The area where the epoxy will be applied must have a rough, scratchy surface to ensure that the new sealer and enamel bond to the toilet lid properly.

Step 2: Apply the Epoxy

Mix the epoxy, according to the directions given, on a piece of cardboard. Use a toothpick to mix it together and then begin applying the epoxy into the area on the toilet lid where the chip is. Work as quickly, but as carefully, as you can. If the piece that has chipped out is still available, set it into place. If not, fill the entire area with epoxy, shaping it as you work. Allow the epoxy to completely dry and set before continuing on to the next step.

Step 3: Apply the Porcelain Enamel

After the epoxy has had time to bond, usually overnight, it is time to apply the porcelain enamel so that the area where the chip was blends into the rest of the toilet lid. Paint this area with a porcelain enamel that is specifically designed for such applications, and make sure the new color will match the old color. If the tint is a little off, you can simply paint the entire lid so that it blends, or you can run down to the nearest paint store and have then try to match the color better. Either way, once you are ready to apply the porcelain enamel, brush it on with a soft brush, or with a painting sponge. Coat the area with at least two layers and allow it to dry before touching.

Following these simple steps will effectively fix any size or shape of chip within a toilet lid. The hardest part of this process is matching the paint colors because there are so many variations. The best way to solve this dilemma is to purchase enough of a specific color to redo the entire toilet, which will ensure that the colors all blend together, and the toilet will be turned into a color and design that fits into the rest of the bathroom décor.
