How to Paint Aluminum Garage Doors: A Comprehensive Guide

Aluminum garage doors are a popular choice due to their durability and low maintenance requirements. However, over time, they can become scratched or faded, making them look old and worn. Painting aluminum garage doors is a great way to restore their appearance and protect them from the elements.

Painting aluminum requires proper preparation, the right supplies, and the right technique. Here's a step-by-step guide to help you paint your aluminum garage door like a pro:

Materials Needed:

TSP Cleaner
Sandpaper (120-grit and 220-grit)
Tack cloth
Metal primer
Aluminum-compatible paint
Roller or sprayer
Paintbrush
Masking tape
Drop cloths

Step 1: Preparation

Begin by thoroughly cleaning the door with TSP cleaner to remove any dirt, oil, or debris. Allow it to dry completely.

Step 2: Sanding

Lightly sand the door with 120-grit sandpaper to create a rough surface for the primer to adhere to. Wipe away any dust with a tack cloth.

Step 3: Apply Primer

Apply a coat of metal primer to the door, following the manufacturer's instructions. This will help the paint adhere better and prevent corrosion.

Step 4: Sand Again

Once the primer is dry, lightly sand the surface with 220-grit sandpaper to smooth it out. Wipe away any dust.

Step 5: Painting

Apply two coats of aluminum-compatible paint, allowing each coat to dry completely before applying the next. Use a roller or sprayer for larger areas and a paintbrush for edges and corners.

Step 6: Cleaning Up

Remove the masking tape and any drop cloths. Clean up any paint spills or splatters immediately. Allow the door to dry completely before operating it.
