How to Paint Aluminum Garage Doors

Painting aluminum garage doors is an ideal way to enhance the curb appeal of your house while also personalizing and safeguarding them. Aluminum is a robust and long-lasting material, but it can gradually deteriorate or become discolored over time. By painting them, you not only improve their appearance but also add a layer of protection against the elements.

Painting aluminum garage doors is a straightforward procedure that can be finished in a few hours with the right tools and preparation. Follow these detailed instructions to give your garage door a fresh, new look:

Materials You'll Need:

Exterior-rated paint for metal
Primer for metal
Fine-grit sandpaper
Trisodium phosphate (TSP) cleaner
Stirring stick
Roller with extension pole
Paintbrush

Step-by-Step Instructions:

Step 1: Preparation

Start by thoroughly cleaning the garage door with TSP cleaner and water. Use a scrub brush to remove any dirt or grime, then rinse well. Allow the door to dry completely before moving to the next step.

Step 2: Sanding

Lightly sand the garage door with fine-grit sandpaper to create a smooth surface. This will help the primer and paint adhere better. Be sure to remove any sanding dust before proceeding.

Step 3: Priming

Stir the primer thoroughly, then apply it to the garage door using a roller and extension pole. Use a paintbrush to apply primer to any corners or edges that the roller cannot reach. Allow the primer to dry according to the manufacturer's instructions.

Step 4: Painting

Stir the paint thoroughly. Using a roller and extension pole, apply a thin, even coat of paint to the garage door. Be sure to follow the grain of the metal, and avoid applying paint too thickly.

Allow the first coat of paint to dry completely before applying a second coat. Once the second coat is dry, your garage door is complete!
