Toilet manufacturers cover repairs to the toilet's hardware, under your warranty. Unfortunately, your warranty doesn't cover chips and cracks that occur from minor wear and tear. When a crack appears, it quickly turns into a chip. Chipped porcelain makes the toilet look old and gives your bathroom a sloppy or messy look. Repairing the chip takes a short amount of time and makes the toilet look brand new.
Clean the toilet with bathroom cleaner, focusing on the area around the chip and the chip itself. Moisten the sponge with cool water and wipe off the cleaner. Thoroughly dry the chip with paper towels or let air dry.
Sand the chipped area of the toilet carefully with fine grade sandpaper. You need to create a slightly rough surface, which helps the adhesive stick better. Wipe away any porcelain dust from the toilet.
Mix the epoxy, if you're using a two-part process, on a small piece of newspaper. If you're using a premixed epoxy, squeeze a small amount onto the newspaper.
Dip the toothpick in the epoxy adhesive and apply it directly to the toilet chip. If you have the piece that chipped off the toilet, place it on the epoxy and hold for several seconds, until a bond forms. Let the epoxy dry overnight.
Paint over the epoxy, using a porcelain enamel that matches the colour of the toilet. Once you have an even coating over the epoxy, let the enamel dry.
Smooth the epoxy down until it's even with the rest of the toilet. If you have uneven or rough edges, you may need to sand the epoxy lightly before painting over it with the enamel.
