Instructions

  1. 1

    Clean the area to be repaired with a sponge dampened with oven cleaner. Bits of grease or food debris can cause the porcelain enamel repair liquid to refuse adhesion to the exposed steel beneath the chip or the porcelain enamel surface of the oven wall.

  2. 2

    Dry the chip/cracked area with a paper towel. The oven wall, like some bathtubs and washing machine drums, consists of a painted finish and steel. According to the Friendly Plumber website, porcelain enamel is baked onto a steel foundation. Porcelain enamel resists high heat and is easy to clean.

  3. 3

    Unscrew the lid of the high heat porcelain enamel repair solution. According to Find a Fix website, high heat porcelain enamel repair liquid requires no mixing. Porcelain enamel repair liquid is available in a variety of colours. Choose a colour to match the interior of your self-cleaning oven.

  4. 4

    Hold the cap which has an attached brush applicator and paint the crack or chip with the porcelain enamel repair liquid. Completely cover the chip or crack. If the chip is deep, you will need to apply multiple layers to make the repair area level with the porcelain enamel surface of the self-cleaning oven wall. Allow each layer of repair liquid to completely dry before applying another layer. Wipe any repair liquid drips away with a damp paper towel.

  5. 5

    Allow the porcelain enamel repair liquid to dry about three hours before operating the oven. Read the high heat porcelain enamel repair solution packaging carefully as some repair liquids require a longer drying and/or curing/bonding time.

  • Porcelain enamel repair liquid is a temporary repair that must be reapplied frequently and usually after heating the oven above 218 degrees C. Permanent repairs to porcelain enamel surfaces require intense heat to bake the enamel to the steel surface and must be accomplished by professional services.
