How to bake enamel spray paint

The technique of enamelling has been used for centuries. A paint is applied to a surface that can withstand being fired to high temperatures. The entire object is then placed in a kiln so that the powder in the paint melts and fuses to form a hard surface. Modern materials, such as sprays and catalysts to allow low-temperature firing, have made the process much easier and more widely used.

  1. 1

    Thoroughly clean the object that is to be painted. Wipe it down with alcohol and allow it to dry completely.

  2. 2

    Spray the enamel paint evenly, ensuring that no drips or runs appear. Allow the paint to air-dry. Depending on the paint used, this can be from two to 24 hours. Check dryness by touching lightly in a hidden area.

  3. 3

    Bake the project in an oven or kiln at 148 degrees C (300 degrees F) for 45 minutes. Smaller projects can be baked for less time, depending on the amount of paint used.

  4. 4

    Allow the project to cool completely before removing from the kiln or oven. Enamel can be applied again if there are any bare spots, or if a second layer is needed.

Tips and warnings

  • Check instructions on the spray can for specific drying times and to verify temperature and time for firing, as different brands can vary.
  • Multiple thin coats will result in a better finish than one thick coat of paint.
  • Some enamels can release fumes or should not be fired. Check the label before using and ensure adequate ventilation
  • Be certain the object being painted can withstand firing temperatures.
