If you want to paint an existing steel door, you should check the manufacturer’s recommendations and warranty information, especially if you have a custom or specialty door. In some cases, making changes to the finish of your steel door can void the door’s warranty. If you just have a standard steel door, then painting it won’t be an issue.

This is the best option, because this type of paint will expand and contract as the door is faced with warm and cold temperatures changes throughout the year. When it comes to painting steel windows, experts recommend going with an acrylic enamel exterior paint, instead of latex to create a harder finish and better stand up to the elements.

The process for painting steel doors is pretty straightforward.

  1. Check your warranty to ensure painting your door is allowed under the terms of your door’s manufacturer’s warranty. In some cases, painting the door is required for the warranty to be valid. In other cases, painting the door could void the warranty. 
  2. If possible, take the door off the hinges, so you can paint it laying down. This isn’t required, but it’s much easier to evenly paint a horizontal surface than a vertical one. Laying the door down will also eliminate drips in the paint. 
  3. Remove any hardware like doorknobs, knockers, etc, when possible. If the hardware can’t be easily removed, then tape over and around it to avoid getting paint on it.

  1. The next step is to prepare the door for paint. The process for this step will depend on what your current door looks like. To start, you’ll want to clean and degrease the entire door. Then, if there’s any chipping or cracked paint, you’ll need to remove the old paint with a paint stripper or heat gun. 

    Don’t use an abrasive to remove paint, because you risk damaging the surface of the door. Once you’ve removed any old flaking paint, you should lightly sand the entire door to create a good surface for the paint to stick to. Be sure to use a light grit sandpaper and be careful not to damage the surface of the door.

    If you’ve stripped the door down to the original surface, you’ll want to start with a primer before painting. Wipe the door down to ensure there’s no dust on the door before painting.

  2. Once the door is properly prepared, it’s time for paint. You should use a foam paint roller for the flat areas of the door and an angled sash brush for any grooves or panels. Each side should get a minimum of two coats of paint, and each coat should be allowed to dry completely before another coat is added. Allow the entire project to dry for at least 12 hours before reinstalling.

  3. Once the paint is set, you can remove the tape, replace any hardware and reinstall the door.
