How to Cure Oven Paint

Restoring a cast iron wood oven is an involved process that includes rust removal and refinishing. Curing, also referred to as "burning-off," is the concluding step in the painting phase of finishing a stove. The stove is heated to a high temperature for a period of time to cure the resin in the paint, consequently giving the paint its heat-resistant properties. Curing can create an accumulation of smelly smoke, making preventative measures to avoid inhalation of noxious emissions imperative for safe curing.

Fans

Instructions

- 1
  Open all of the windows and doors to provide adequate ventilation. Place fans near windows, facing outwards to help push the curing emissions out of the room. Open the chimney and any other nearby vents.
- 2
  Close the doors of bedrooms and other separate rooms to block them of any emissions.
- 3
  Start a roaring fire in the oven. The fire should have the energy to reach 475 degrees F for at least 25 minutes.
- 4
  Allow the fire to die-out but keep the environment ventilated until the smoke and smell disappear.
- 5
  Wait for the oven to fully cool then ventilate the space again and start a second fire. The emissions should be noticeably reduced. Allow the fire to die and the stove to cool.
- 6
  Cure the oven at least one more time, or until emissions are no longer detected. The finish of the stone paint should have transitioned to a rich matte-black finish.
