Painting Aluminum Siding

Compared to wood, aluminum siding is very durable and low maintenance. You have to stain your wood fence and siding to make it last in the long run, while aluminum works fine without any treatment. However, it is not the most attractive material. If you want your aluminum siding to look better or change its color, there are ways that you can do this on your own.

Preparation and Tools

Painting aluminum siding is more difficult than painting wood because it is smooth and has no pores. In comparison, painting your outdoor deck board could be a lot more complicated compared to painting aluminum. The paint will stick to the metal from the outside. However, you still need to ensure that your surface is prepared correctly before applying any finish.

There are two kinds of surfaces on aluminum siding: brushed and anodized. Anodized is the most popular because it has a hard finish that resists scratching and fading. Anodizing makes it more slippery than brushing, so painting will be more difficult.

You cannot paint aluminum siding with oil-based paints or primers because it will corrode the metal. The only type of paint that you can use is latex. You can find exterior latex paints in light or dark colors suitable for painting aluminum siding. The only drawback is that they may fade after a few months if you don’t apply a clear topcoat to protect the base color.

When it comes to painting aluminum siding, you will need a brush and some spray paint. You should not use a roller because that can make the paint look too thick and cause more problems in the future.

Techniques and Materials

There are different ways to paint aluminum siding, but the best way is to use exterior latex paint in a spray can. If you want to do it right and not have any streaks, follow these steps:

  • Apply masking tape around windows and doorframes to protect them from paint or other damage.
  • Use low pressure when spraying paint.
  • Spray paint in a “Z” shape to cover each section. Then move to another part of your siding. After, let the paint dry for 12 hours before removing the tape without leaving adhesive on your paint.
  • If you want to use a clear topcoat, brush it on and dry it.
  • If you want to avoid the hassle of removing the masking tape and your exterior latex paint doesn’t have a protective coating. You should wait 24 hours before painting over it again. This will give you a longer-lasting finish that will prevent peeling and flaking.
  • Do not hold the can too close to your surface.
  • When you are finished painting aluminum siding, make sure to clean your tools and brushes with water. This will help to prevent any contamination on future projects.

Now that you know how to paint aluminum siding, you will need to find a good brand of exterior latex paint. This will affect your project, so make sure it is high quality and offers excellent coverage. You should also choose colors that match the surroundings, or they might not work well.


To paint aluminum siding, you need to clean and prepare the surface before applying paint. This includes removing any dirt or debris from cracks in the sheeting and sanding down rough edges to prevent the peeling of your finish coat later. And using a metal prep product if necessary. It is best to use an aerosol can of paint specifically designed for metal.

If you cannot get the siding clean, using a product like Valspar’s Rust Cure is best. It will make rust go away and prepare your surface for painting. This will make it easier for the paint to stick when we paint later on. First, we should put metal primer all over the house, and then we can put oil-based enamel on top of that to protect against weather or cold temperatures.

If you want to refinish the aluminum siding on your house, it is best to hire someone experienced in doing this. In the long run, it will save you both time and money. You do not need to buy supplies if they are already available.

Maintenance for Aluminum Siding Paint

The final step in painting aluminum siding is to maintain it. How frequently your property is exposed to the sun and the temperature depends on where you live. Your house may require occasional touch-ups or repainting every few years. You may also need to reapply a protective coating once a year. This depends on how often you clean and maintain your siding.

You can use the same paint you used for your initial coat. Still, if you want to change the color a little, it’s easy to mix different colors when applying the second round of coats. A great idea would be a darker shade of paint on top of a lighter one. This will create a dynamic color change while still showing some of the original aluminum sidings beneath.
