Can You Paint Aluminum Siding?
Aluminum siding has been a popular choice for homeowners since the 1940s due to its durability and ease of maintenance. However, over time, aluminum sidings can fade and lose their original shine, leaving homeowners with an unsightly exterior. Fortunately, painting aluminum siding can be a feasible solution to this problem and an affordable alternative to replacing it altogether. In this article, we will explore the steps needed to paint aluminum siding, the benefits and drawbacks of this option, pre-painting preparation, common mistakes to avoid, types of paint and necessary tools, and how to maintain your newly painted aluminum siding.
A Step-by-Step Guide on How to Paint Aluminum Siding
Painting aluminum siding can be a tedious process, but it is a project that can be tackled by homeowners with a bit of patience, preparation and right tools.
Step 1: Power wash your siding
Before painting, the siding needs to be clean and free of all dirt and debris. Using a pressure washer, wash the looks from the bottom or top. Avoid using too much pressure and do not aim the washer too close to the siding to avoid damage.
Step 2: Sand and Fix Fainting or Damaged Areas
After washing your siding, inspect its condition and make sure there are no fading, scratches or damages. If needed, sand and caulk the problem areas to create a smooth painting surface.
Step 3: Prime the surface
Using a quality oil-based primer or a primer specialized for metal, coat the aluminum siding to make sure that the paint will stick and last longer.
Step 4: Apply Two Layers of Paint
Select a high-quality 100% acrylic paint designed for exteriors and apply it in two separate layers. Follow the manufacturer’s instructions and make sure you work in the right temperature and humidity conditions.
Step 5: Perform Touch-Ups
Once the first coat of paint dries, inspect the surface for any missed spots or any paint drips that need to be sanded down with fine-grit sandpaper before applying the second coat of paint.

Top 5 Tips for Preparing Your Aluminum Siding for Paint
Preparing your aluminum siding for painting is one of the most crucial elements of the process. Proper preparation ensures a smooth painting surface and results in a long-lasting finish.
Tip 1: Start with A Clean Surface
Clean your aluminum siding from top to bottom by washing it with a power washer and treating any stains or mildew with a cleaning solution. Rinse the siding thoroughly and make sure it is completely dry before proceeding to the next step.
Tip 2: Remove Peeling Paint
Use a paint scraper to remove any loose or peeling paint from the surface of the siding. Make sure to scrape carefully to avoid damaging the surface of the siding.
Tip 3: Sanding is Crucial
Sanding the aluminum siding provides a good surface for the paint to adhere. Use a fine-grit sandpaper or sanding block to create a smooth yet slightly uneven surface which will take to the primer easily.
Tip 4: Prime the Surface
Priming the surface prepares the aluminum surface to accept the paint. It is essential for adhesion and is especially important to use if your original paint is oil-based. Choose a primer that is appropriate for aluminum siding and apply it with a sprayer or by hand with a paintbrush.
Tip 5: Protect Your Home’s Exterior
Cover any areas of your home’s exterior that are near the area you are painting. Use plastic or a tarp. This will keep the paint from sticking to other areas of your home and potentially damaging them.
Common Mistakes to Avoid When Painting Your Aluminum Siding
Mistakes happen, but some common ones can be avoided with some preparation and knowledge.
Mistake 1: Skipping Preparation
The biggest mistake you can make is failing to prepare your aluminum siding correctly. Skipping the preparation process can result in a paint job that is botched and peels away from the siding.

Choosing the wrong type of paint is another common mistake. Make sure you read the manufacturer’s instructions carefully and choose paint designed specifically for aluminum surfaces.
