Things You'll Need
Professional painter's tape
Galvanized metal etching spray primer
Heat-resistant appliance enamel spray paint
You can paint the inside of a dryer drum as long as you choose the proper coating. Before you begin, consider that many dryer drums are composed of bare galvanized metal. Paint will not adhere to bare metallic surfaces unless they are conditioned with a special acidic primer. Once the drum is properly prepared, it will accept its new finish. Select a special heat-resistant appliance enamel, or the finish will not remain durable in the long run.
Unplug the dryer and ensure that it is cool.
