The 5 Factors to Consider When Choosing Paint for a Metal Garage Door

1. Weather Resistance

Your garage door is exposed to the elements, including UV rays, rain, snow, and temperature fluctuations, so choosing a paint that is formulated for use on exterior metal surfaces is essential.

Look for a product with good weather resistance that can withstand exposure to sunlight and rain, and significant temperature changes.

2. Type of Paint

There are different types of paint available for metal garage doors. Some of the popular options are water-based and oil-based paints. Pick according to your preference, budget, and the type of finish you want.

3. Price

The price of the paint is another important factor to consider. While you will likely get what you pay, some affordable paints can still provide high-quality finishes.

You should research the prices of different brands and determine which ones are within your budget. Additionally, you might want to consider the cost of hiring a professional painter or painting the door yourself.

4. Paint Quality

Investing in quality paint will save you money in the long run. Paints formulated for metal garage doors will better adhere to the metal and last longer. Good paint products will have excellent coverage and durability, will not fade, peel or crack over time, and resist chalking.

5. Ease of Application

Finally, consider its ease of application when selecting paint for your metal garage door. Some products dry quickly, while others dry too slowly, causing bubbles and lifting. Look for paint that applies smoothly, is self-leveling, and dries evenly. 

What Type of Paint Is Best?

Water-based Paint

Water-based paint (acrylic or latex) is a type of paint where the binder and carrier are primarily water. This paint has gained popularity due to its environmental friendliness and ease of use. Exterior-grade water-based paint can be used for metal garage doors, but it is not the most durable option.


  • Fast Drying: Water-based paint typically dries faster than oil-based paint.
  • Easy Clean-Up: Brushes and spills can be cleaned easily with soap and water.
  • Low Toxicity: It has lower volatile organic compound (VOC) levels than oil-based paint.
  • Flexibility: It tends not to become brittle over time, so it’s less likely to crack.
  • Fade-Resistant: Most water-based paints resist UV light better than oil-based paints, so colors stay vibrant longer.


  • Poor Adhesion: Water-based paints can sometimes struggle to adhere to slick, glossy surfaces or raw metal without proper preparation.
  • Could Encourage Rust: If applied directly to metal, water in the paint could encourage rust development.
  • Less Durable: Generally, they are less durable than oil-based paints.
  • Weather Sensitivity: Water-based paint is sensitive to weather conditions during application.
  • Thinner Finish: They usually provide a thinner finish, which may require multiple coats for complete coverage.

Oil-Based Paint

Oil-based paint, also known as solvent-based paint, is a type of paint where the binder is a type of oil or alkyd, and the carrier is a type of organic solvent. It’s known for its durability and rich, glossy finish.


  • Durability: Oil-based paints are generally more durable than water-based paints.
  • Adhesion: They adhere well to surfaces, including metal, and can even help seal out moisture.
  • Smooth Finish: Oil-based paints often leave a smooth, glossy finish that hides imperfections.
  • Coverage: They provide excellent coverage with fewer coats.
  • Resistance: They offer good resistance to wear, so they’re ideal for high-traffic areas.


  • Drying Time: Oil-based paints take longer to dry than water-based paints.
  • Clean-Up: Clean-up requires solvents like mineral spirits or turpentine.
  • Toxicity: They contain higher levels of volatile organic compounds (VOCs), which can harm the environment and your personal health.
  • Yellowing: Over time, white or light-colored oil-based paints can turn yellow.
  • Brittle: They can become brittle, leading to cracks or peeling.

What Paint Finish Is Best?

When painting metal garage doors, it’s important to choose the right type of paint finish. For the best look and durability, semi-gloss or gloss finishes are recommended.

Semi-gloss finishes have a subtle shine and are less likely to show flaws or imperfections in the metal compared to high-gloss finishes. They are also easier to clean and maintain.

On the other hand, high-gloss finishes offer a more dramatic shine and can give off a sleek, modern look. However, they are more prone to showing imperfections and may require more frequent touch-ups.

In terms of durability, both semi-gloss and gloss finishes are great options. They resist scratches, fading, and weather damage, making them ideal for exterior metal surfaces.
