Painting your metal garage door: How to go about it?

Follow this methodical approach to simplify the process of painting your metal garage door.

Prepare the surface

In the first place, you need to prepare the metal surface for cleaning. So, clean the door thoroughly, so that you can do away with the grease, grime, and dirt.

Prepare a mild detergent solution and use a brush to scrub the surface with it. This way, you can easily eliminate stubborn stains. Next, use clean water to rinse the door and let it dry completely.

Look out for rusted patches on the surface. In case you come across one of these, use sandpaper or a wire brush to remove it.

This way, you will have a clean surface to work on. Apply a rust-resistant primer to the affected areas to prevent further damage.

Put aside hardware components

We all love a neat and professional finish on metal garage doors. So, remove the hardware components from the door, such as locks, handles, and hinges.

This approach would allow you to coat the door evenly with paint without encountering any obstructions. Detach the hardware using a screwdriver or other suitable tools.

Take care to cover the surrounding areas like the walls or windows using painter’s tape or plastic sheets. This would protect them from accidental paint spills or drips.

Choose the right paint

To achieve a professional finish on your metal garage door, it’s imperative to use the right type of paint. It’s advisable to use a high-quality exterior paint formulated for metal surfaces.

Also, read the label and make sure to use rust-resistant paint to achieve a perfect metallic finish. This ensures the durability and longevity of the metal door.

Consider the climate in your area while choosing the paint. Places with extreme weather conditions like high moisture or long exposure to UV rays require you to use high-quality paints.

Prime and paint the door

When you explore how to paint your garage door, it’s easy to overlook the priming process. Make sure to apply a layer of primer on the metal surface before using the external coat.

This ensures that the superficial coat can properly settle on the base layer. Use a primer formulated only for metal surfaces. Use a roller or a brush, so that the primer looks even on the surface.

Once you apply the primer, the metal garage door is ready to be painted. Stir the paint thoroughly at the outset to make it consistently even.

You may either use a paint sprayer or a brush to apply the paint evenly, working from top to bottom.

If you’re using a paintbrush, get one with synthetic bristles. These brushes are compatible with oil or latex-based paints.

Use smooth and long strokes, so that the brush doesn’t leave any marks on the door.

In case you decide to go with a paint sprayer, adhere to the manufacturer’s guidelines to get the best finish. Use appropriate protective gear like a mask and goggles when you use a sprayer.

Your metal garage door would need two coats of paint. After applying the first coat, leave adequate time for the paint to dry before proceeding to the second coat.

This way, you will get a rich and smooth coating on the garage door. Closely observe the paint drips or uneven areas, and do the needful to correct them.

Adding the finishing touch and maintaining your garage gate

When the final coat of paint on your metal door dries up, reattach the hardware that you removed earlier. Fasten all the components firmly and align the hardware.

Inspect the door for a flawless finish by taking a few steps back.

Even after painting the door, you need to maintain the metal surface from time to time. This calls for regular inspection, which warrants a long lifeline to the door.

Occasionally, clean the door using a mild detergent and sponge. Remove the debris and dirt that accumulates on it.

Also, refrain from using rough materials or abrasive cleaners that might potentially damage the paint.
