What You'll Learn
Identify rust spots
To identify rust spots on your garage door, start by inspecting the entire door thoroughly. Pay special attention to areas that are particularly prone to rust, such as the bottom, edges, joints, and any exposed metal surfaces. Look out for "bubbles" forming under the paint, paint-free spots, or reddish-brown flakes of corroding metal. Remember to be very organised with your inspection and don't forget to include the in-between areas. It is recommended to wear utility gloves to avoid nicks and cuts during a more in-depth tactile inspection.
If your garage door is made of steel, it is important to note that while it can rust, it is much less likely to do so when you apply a protective coating. With this coating, steel garage doors can hold up against a variety of weather conditions. On the other hand, if your garage door is made of wood, it will not rust, but it can rot or decay in conditions of excess moisture.

Clean the affected area
To clean the affected area of rust, you will need to remove the rust without damaging the paint. There are several methods to do this. One option is to use a product like WD-40, which is designed to loosen the bonds between rust and the metal surface. Simply spray it on the rusted surface and let it sit for around ten minutes. Then, scrub away the rust with a light abrasive on surfaces without paint. You can avoid further damage to the paint by masking the surface while you work.
Another method is to use vinegar or any other acid. Soak the affected area in vinegar overnight, then scrub the rust off the next day. Make sure to clean the surface afterward to remove any residual acid, and coat it with oil to prevent future rust (WD-40 can be used for this purpose).
If the rust is underneath the paint, you may need to use fine steel wool and soapy water to remove it without damaging the paint. This method will help remove surface rust without being too harsh on the paint.

Apply a rust converter
Once you have removed the rust and filled in any holes, it's time to apply a rust converter. This is a crucial step in preventing further rust formation and protecting your garage door. A rust converter is a chemical product that neutralises the rust, converting it into a hard and stable compound that can be painted over.
Firstly, make sure you have chosen a suitable rust converter product and that you have read and understood the manufacturer's instructions. Using a brush or spray can, apply the rust converter to the sanded and cleaned surface of the garage door. It is important to ensure that you cover all the rusty areas thoroughly. The rust converter will turn the red rust (iron oxide) into black iron oxide, which is a stable compound suitable for painting.
Allow the rust converter to dry completely. This usually takes a few hours, but it is important to follow the manufacturer's instructions for the specific product you are using. Once it is dry, you can move on to the next step, which is applying a primer. The primer will provide an extra layer of protection for the metal surface and help the paint adhere better.
By applying a rust converter, you are not just covering up the rust but also treating it chemically, ensuring that it does not continue to spread and cause further damage to your garage door. This step is an important part of the restoration process, helping to extend the life of your garage door and improve its appearance.

Apply primer and paint
Before applying primer, ensure you have removed any rust, chipped paint, and cleaned the door. You can use a scraper and an electric sander with coarse-grit sandpaper to remove the rust and old paint. For corners and small areas, use a sheet of sandpaper. Sand the door again with medium-grit sandpaper to smoothen the surface.
Once you have a smooth surface, repair any dents or holes with a bonding agent intended for metal. Do not use wood filler or spackling material as it will not adhere to the metal. Use a putty knife to fill the holes and let the filler dry completely. Sand the filler with fine-grit sandpaper to smoothen the surface.
Now, your garage door is ready for priming. Use a high-quality metal primer to prime the garage door. Most metal primers offer excellent rust protection. Follow the instructions on the primer can. Some primers may require sanding between coats, while others may require sanding before painting. Ensure the metal primer is completely dry before applying paint.
For optimal results, apply thin coats of paint and follow the guidelines on the paint can. Thin applications prevent dripping and allow the paint to dry faster. Most metal paints require at least two coats for thorough coverage, while some may demand three or more coats.

Prevent future rusting
To prevent future rusting, it is important to understand what causes rusting in the first place. One of the biggest contributors to rust on garage doors is the environment. If you live in a coastal area, the salt in the air can cause corrosion. Similarly, if you live near industrial areas, the chemicals in the air can also cause rusting. In northern areas, de-icing materials on the road can splash onto the garage door and lead to rust.
To prevent rust from setting in, you should treat your garage door in the same way you would treat your car. Anytime you see exposed or raw metal, you should repair it immediately. Keeping your garage door clean is also important. Washing your garage door regularly will help remove dirt, grime, street salt, and industrial chemicals that can damage the door's surface.
It is recommended to scrub your garage door at least twice a year, or more frequently if you live in an area with harsh climates. You may also want to consider waxing your door for extra protection.
Additionally, you should watch out for grease spots and oil stains, as these can compromise the integrity of your paint coating. If you notice any exposed metal, be sure to repair it right away to prevent rust from forming.
- Wash your garage door regularly with car soap or dish detergent to remove dirt, grime, and corrosive materials.
- Avoid pressure washing your garage door, as this can damage the protective paint layer.
- Treat grease spots and oil stains promptly to prevent them from compromising the paint.
- Keep your garage door well-waxed to provide extra protection against the elements.
- If you live in a coastal or industrial area, consider taking extra precautions such as regular inspections and touch-ups of the paint coating.
- Always repair any exposed metal immediately to prevent rust from forming.
