If you would like to paint a hob appliance, there are some important things you must consider before you begin the paint-application process. Because hob appliances are ill-suited for adhesion, you must abrade them with sandpaper to provide "teeth" for the paint to stick to. In addition, you will need to select a particular type of paint, one capable of remaining durable in the face of heavy friction and high temperatures.
Clean the hob appliance with a trisodium phosphate cleanser, using a plastic brush. Rinse the appliance with wet rags. Use towels to dry the appliance.
Enhance surface adhesion by abrading the hob appliance. Scour the appliance with 120-sandpaper until it feels slightly gritty.
Cover areas you do not want painted with masking paper and painter's tape. Protect the floor beneath the appliance with a fabric dust sheet.
Coat the abraded appliance with appliance epoxy spray paint. Hold the can 8 inches from the appliance as you apply.
Wait a full day before using the appliance.
Wear a respirator if you are working in a poorly ventilated area.
Do not paint over a dirty or greasy surface, or you will have adhesion problems. Don't paint over an unsanded appliance, or the finish may fail. Don't use a plain acrylic-latex or oil-based paint on a hob appliance, as they will not provide adequate heat resistance and durability.
