When painting aluminum siding, opt for a high-quality acrylic paint designed specifically for exterior surfaces. For the best results, start with an oil-based primer followed by 100% acrylic paint for lasting durability and longevity. Avoid latex-based paint, as it reacts with the metal, leading to bubbling, peeling, and premature wear.
Painted aluminum siding can last about 15 years if applied correctly. Proper surface preparation—including cleaning and applying paint and primer in temperatures between 50 and 80 degrees—is crucial for longevity. It’s also important to avoid painting in rainy conditions, as moisture can interfere with adhesion and lead to premature peeling or fading.
Unlike other siding materials, aluminum siding doesn’t always show obvious signs that it needs repainting. However, if your siding fades, oxidizes, or becomes chalky, it may be time to consider repainting. Subtle fading can be hard to notice, but it's time for a fresh coat of paint if you see white, chalky residue on your hands and clothes when you touch the siding.
Spray painting aluminum siding offers significant benefits compared to other application styles. Spray painting delivers even coverage, rapid application, and enhanced adhesion compared to traditional painting methods. This technique ensures every surface is evenly coated, minimizes labor time, and provides a sleek, professional finish that withstands weather and oxidation for lasting results.
