If your steel garage door has rust, it has already begun to corrode. It is not uncommon for a garage door to start rusting at the bottom where contact with rain and corrosive materials is more likely. Don’t procrastinate if you see evidence of oxidation. It can spread quickly, reduce curb appeal, and possibly lead to expensive repairs. Fortunately, you may be able to remove the rust. Continue reading to learn how to remove rust from a garage door in Las Vegas.

Removing Rust from Your Garage Door

If you have a modern garage door, it is most likely resistant to rust. Older steel doors, on the other hand, tend to corrode over time. When you inspect your garage door, start at the bottom where rust is most likely to appear, and look elsewhere for any spots of corrosion.

To remove rust safely and successfully before there’s a serious problem, follow these steps:

  • Close the garage door and turn off the electrical supply to the garage door opener.
  • Clean the door with a cloth soaked with warm water and soap, starting at the bottom or where you see the most rust. The door should then be allowed to dry.
  • Soak a cloth in white vinegar and wipe the rusty section. Then use a steel wool pad to scrub the rust and help it dissolve; it’s important to be thorough as any leftover spots can spread again.
  • Using sandpaper, sand down any part of the garage door where there is rust. Continue sanding about 2 inches around areas of oxidation.
  • Use a metal bonding agent to fill any holes in the door and wait for it to dry. Sand the filled area with a fine-grit sandpaper. When the process is complete, wipe off any dust to make sure the surface is smooth and clean.
  • After the door is sanded and filled, apply a zinc chromate primer to prevent additional rusting, and wait until it is dry to paint the garage door.
  • Using a rust-resistant paint that matches the color of your garage door, apply a coating that protects it from future corrosion. It’s best to paint the entire door to prevent freshly painted areas from standing out, or flashing.
  • Some types of doors may require specific painting products or rust-removal/painting methods. Check with the manufacturer or owner’s guide if there are any specific requirements for your garage door model and brand.
  • Spray painting is commonly used for garage doors. If applying a spray paint, use painter’s tape and newspaper to protect areas surrounding where you applied the primer. You can also apply the paint directly using a paintbrush or roller (but be sure the paint is applied smoothly to avoid drips).

When Should I Not Remove Rust?

If there’s so much rust attempting to remove it risks damaging the garage door, consult a professional first. Another reason is if the door is protected under a warranty that covers rust removal. Proceeding yourself then risks voiding the warranty. Your garage door manufacturer will fix the problem at no cost anyway, so it’s best to have a skilled contractor handle the job.
