Prepping and Painting Your Aluminum Siding
Painting your aluminum siding isn’t about grabbing a bucket of paint, brushes, and getting to work. It’s a little bit complicated. Before using the paint brush, the exterior should be cleaned and primed so the paint doesn’t peel later.
Let’s discuss the step-by-step method to prep and paint aluminum siding:
- Clean The Siding With TSP
If you don’t want dirt sticking to the paint, then make sure to clean the aluminum siding with a mild detergent or a cleaning agent like TSP (Trisodium Phosphate).
You can scrub the side using a brush or use a power washer for best results while saving your time. After you’re done cleaning, make sure to wait at least 24 hours for everything to dry.
- Light Sanding
Sanding helps the paint stick better as the slick surface is roughed up. While sanding, make sure to use a medium grit sandpaper (150-220 grit) and focus on glossy areas while wiping away the dirt once you’re finished; these steps help when you are ready to paint. Helping preserve your property siding for a long time.

This helps in achieving a quality finish, better strokes, and prevents stains from bleeding through. Using a primer also results in less paint consumption, saving you time and money
- Stroking The Paint Brush
After you are done cleaning and priming the surface, it’s time to grab the brush and start painting. Fine strokes that make your siding shine bright and look like new. The paint adhesion is better and won’t peel off quickly, as the surface is primed and roughed up with a medium grit sandpaper.

- Final Curing And Drying
After you are done with the final coat of paint, allow it to dry for at least 24 hours. Curing is the process where the paint fully hardens and reaches its maximum durability and adhesion.
