How to Paint Metal Garage Door

Summary: To paint a metal garage door, you need to prepare the surface properly by cleaning it thoroughly, removing any rust or old paint, and sanding it down to create a smooth surface. Then, apply a primer to protect the metal and help the paint adhere better. Once the primer has dried, apply the paint to the garage door using a paintbrush or roller.

Can You Paint Metal Garage Door?

You can paint your metal garage door to protect it from the elements and improve its curb appeal. Painting your door is relatively simple, but choosing the right type of paint is essential, and preparing the door properly before painting. You can give your garage door a new look with a little time and effort. You can also add a new layer of protection against the elements.

You can skip the priming step if your garage door is already primed and painted. If not, you’ll need to prime the door before painting it. Choose a primer that is specifically designed for metal surfaces. Apply the primer with a brush or roller, and follow the manufacturer’s instructions for drying times. Once the primer is dry, you’re ready to paint your garage door.

Types of Paint for Metal Garage Doors

Choosing the right type of paint is important for painting your garage door. You’ll want to choose a paint that is specifically designed for metal surfaces. Here we have given the best type of paint to use on a metal garage door.

  • Oil-based Paint: This is durable and ideal for painting metal garage doors. It will provide a long-lasting finish that can withstand the elements. However, oil-based paint can be difficult to work with and clean up. It also has a strong odor.

  • Latex Paint: Latex paint is easier to work with than oil-based paint and has little to no odor. It’s also easier to clean up. However, latex paint isn’t as durable as oil-based paint and may not last as long. If your paint job is exposed to the elements, it may start to fade or chip over time. You must be sure to choose good quality latex paint designed for metal surfaces.
  • Acrylic Paint: This type of paint is similar to latex paint but is more durable. It can withstand the elements better than latex paint and won’t fade or chip as easily. Acrylic paint is also easy to work with and has little to no odor. However, it can be more difficult to clean up than latex paint.

Complete Guide on How to Paint Metal Garage Door

Step 1: Gather Necessary Supplies

Before beginning the project, gather all the necessary supplies, including:

  • A high-quality exterior metal paint
  • Primer specifically designed for metal surfaces
  • Paintbrushes or rollers
  • Paint tray
  • Painters tape
  • Drop cloth or plastic sheeting
  • Wire brush or sandpaper
  • Cleaning solution (such as trisodium phosphate, TSP)
  • A sponge or cloth
  • Ladder (if needed)

Step 2: Choose the Right Weather Conditions

Painting a metal garage door requires favorable weather conditions. Choose a day with low humidity and mild temperatures, ideally between 50 and 80 degrees Fahrenheit. Avoid painting in direct sunlight or on a windy day, as these conditions can cause the paint to dry unevenly.

Step 3: Prepare the Garage Door

Remove any loose debris, such as dirt, dust, or cobwebs, from the surface of the garage door. If the door has any rust, use a wire brush or sandpaper to remove it. Thoroughly clean the door using a sponge or cloth and a cleaning solution, such as TSP, to remove any remaining dirt or grease. Rinse the door with water and let it dry completely before proceeding.

Step 4: Protect Surrounding Areas

Use painters tape to cover any areas around the garage door that you want to protect from paint, such as windows, trim, or hardware. Lay a drop cloth or plastic sheeting on the ground beneath the door to catch any paint drips.

Step 5: Apply Primer

Applying primer to the metal surface will help the paint adhere better and provide a smoother finish. Use a paintbrush or roller to apply a thin, even coat of metal-specific primer to the garage door, starting at the top and working your way down. Allow the primer to dry according to the manufacturer’s instructions.

Step 6: Lightly Sand the Primer

After the primer is completely dry, lightly sand the surface with fine-grit sandpaper to create a smooth surface for the paint to adhere to. Wipe away any dust with a clean cloth.

Step 7: Apply the First Coat of Paint

Stir the exterior metal paint thoroughly to ensure even color distribution. Pour the paint into a paint tray and begin applying it to the garage door using a paintbrush or roller. Start at the top of the door and work your way down, using smooth, even strokes to prevent drips and streaks. Be sure to cover the entire surface of the door, including any recessed areas or panels.

Step 8: Allow the First Coat to Dry

Allow the first coat of paint to dry according to the manufacturer’s instructions. The drying time will vary depending on the type of paint used and the weather conditions.

Step 9: Apply a Second Coat of Paint

After the first coat of paint is completely dry, assess the coverage. If the original color of the garage door is still visible or the finish appears uneven, apply a second coat of paint using the same technique as the first coat. Allow the second coat to dry according to the manufacturer’s instructions.

Step 10: Inspect the Finished Surface

Once the paint is dry, carefully inspect the garage door for any areas that may require touch-ups or additional coats of paint. If necessary, apply touch-ups or additional coats and allow them to dry completely.

Step 11: Remove Painters Tape and Clean Up

After the paint has dried and you are satisfied with the results, carefully remove the painters tape from around the garage door. Dispose of the drop cloth or plastic sheeting, and clean any brushes or rollers used during the painting process.

Step 12: Reattach Hardware (if removed)

If you removed any hardware, such as handles or hinges, before painting the garage door, reattach it once the paint is completely dry. Ensure that all hardware is properly aligned and securely fastened.

Step 13: Maintain Your Painted Garage Door

To keep your newly painted garage door looking its best, perform regular maintenance, such as cleaning the door with a mild soap and water solution to remove dirt and debris. Avoid using harsh chemicals or abrasive cleaning tools, as these can damage the paint.

Step 14: Monitor the Condition of the Paint

Over time, exposure to the elements can cause the paint on your garage door to fade, chip, or peel. Monitor the condition of the paint and touch up any areas that show signs of wear as needed. This will help to prolong the life of the paint and keep your garage door looking fresh and well-maintained.

Step 15: Plan for Future Repainting

While a high-quality exterior metal paint should provide years of protection for your garage door, it will eventually need to be repainted. Plan for this eventuality by keeping a record of the paint brand and color used, as well as the date of the painting project. This will make it easier to match the paint when it is time to repaint the garage door.

By following these steps, you can successfully paint a metal garage door and achieve a professional-looking result. Choosing the right paint, preparing the surface properly, and applying the paint in thin, even coats will help to ensure a durable and attractive finish. Regular maintenance and touch-ups will keep your garage door looking its best and prolong the life of the paint.

When Should You Paint Metal Garage Door?

Paint the metal garage door when it needs a fresh coat of paint. A quality paint job can last for years, but the garage door will eventually need to be repainted. If the paint is peeling or bubbling, if the color is faded, or if there are rust spots, it’s time to paint the metal garage door.

A Quality Paint Job Can Last for Years

If you choose high-quality latex paint, it will last longer than oil-based paint. You need to ensure that the surface is cleaned before you start painting.

If the surface is not cleaned, the new paint will not adhere to the door properly and will not last as long. Use a pressure washer to remove dirt, grime, and cobwebs from all door surfaces.

Be sure to let the door dry completely before painting. If there is any mildew, use a solution of one part bleach to three parts water to kill the mold spores. Rinse the door with clean water and let it dry completely before painting.

How to Paint a Galvanised Garage Door?

It is important to note that it must be prepared correctly before you can paint a galvanized garage door. If the door is not prepared properly, the paint will not adhere correctly and will eventually peel off. Therefore, the first step is to clean the door. You can do this by using a pressure washer or a hose with a high-pressure nozzle attachment.

Remove any loose paint, dirt, or grime before painting. Once the door is clean, you will need to etch the surface. This can be done using a specialized etching solution or sanding the door with high-grit sandpaper. Once the door is etched, you will need to apply a primer specifically designed for use on galvanized metal.

After the primer has dried, you can then paint the door with a metal paint of your choice. Again, it is important to use several thin coats of paint rather than one thick coat. This will ensure that the paint adheres properly and does not peel off.
