Acrylic paints are the best choice for aluminum siding as they tend to be more flexible than other types of paint. Additionally, a self-etching primer should always be used before painting aluminum siding. This will help ensure that the new paint adheres to the siding correctly. Apply multiple thin coats instead of one thick coat.

The 4 Factors to Consider When Choosing Paint for Aluminum Siding

1. Quality of Paint

Choose a high-quality paint that will adhere well to the aluminum siding and provide long-lasting protection. A high-quality paint will resist fading, blistering, and peeling.

Though high-quality paint may come with a premium price, it is a long-term investment that will save you money in the long run by avoiding frequent paint jobs.

2. Type of Paint

Choosing the right paint for aluminum siding is essential. There are a few different types of paint available, including latex, oil-based, and acrylic.

Each type of paint has its advantages and disadvantages, so it’s important to know which one will work best for your specific needs. Their level of adhesion, durability, and glossiness can help you determine which one is the best option.

3. Paint Finish

The finish of the paint is another factor to consider. Different finishes can change the look of your siding and can even have an impact on the durability of the paint. The higher the gloss level, the more durable and scratch-resistant the paint will be.

4. Application Method

It’s important to choose the right application method when painting aluminum siding. The most popular methods are spray, roller, and brush.

If you decide to use a sprayer, make sure it’s specifically designed for painting metal surfaces. Rollers or brushes can also be used for larger areas and provide better coverage than spray paint.

What Type of Paint Is Best?

Acrylic Paint

Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and stabilizers. It is water-soluble and very stable, making it an ideal choice for aluminum siding.


  • Durable and long-lasting
  • Resistant to fading, cracking, and peeling
  • Easy to clean with soap and water
  • Can be applied over existing coatings without sanding or priming
  • Available in a wide range of colors


  • Not as resistant to chipping as other paints
  • Can be difficult to apply in cold weather conditions
  • Requires multiple coats for full coverage

Latex Paint

Latex paint is a water-based paint made of pigments, binders, and water-based liquids. It is commonly used for interior projects due to its durability and non-toxic properties.


  • Easy to apply
  • Non-toxic
  • Durable
  • Flexible
  • Low odor


  • May require multiple coats for full coverage
  • Not as resistant to fading or chalking as other paints

What Paint Finish Is Best?

For painting aluminum siding, the best paint finish options are either gloss or semi-gloss. This is because aluminum sidings are exposed to harsh weather conditions, such as sun, rain, wind, and snow.

A high-gloss finish is ideal for aluminum siding as it provides a shiny, reflective surface that is easy to clean and maintain. Not only does it give a sleek appearance, but it also prevents dirt and grime from sticking to the surface, making it easier to keep the siding looking new.

On the other hand, a semi-gloss paint finish is an excellent choice for those looking for a paint finish that strikes a balance between gloss and matte finishes. It offers a subtle sheen that is not as reflective as a gloss finish but provides more shine than a matte finish.

Additionally, semi-gloss paint has higher moisture resistance, ensuring that the aluminum siding remains protected against harsh weather elements.
