Every spring, we get a lot of customers ready to start their spring cleaning checklist by repainting the exterior of their home. We get asked a lot whether or not you can paint aluminum siding, and the answer is YES!

Painting your aluminum siding can be time-consuming, so depending on the size of your home, plan to set aside at least a couple hours per 100 square feet of siding. Also make sure to pick a series of days with warm, dry weather, so your paint will adhere and dry properly.

How to paint aluminum siding

1. Replace any damaged pieces of siding. If you have any missing, dented, or damaged areas, now is the time to replace them! If you have peeling paint on your aluminum siding, be sure to scrape that off before beginning your project.

2. Clean your surface. We know you’re excited to see that new color, but don’t pull out your brush just yet. Clean your siding with a mixture of water, TSP (or TSP-E, if you’re environmentally conscious), and if you have mildew, then a little bleach. TSP (trisodium phosphate) can be found at most home improvement stores, and will have directions for dilution. Use a scrub brush or abrasive sponge to clean your siding, or if you have a lot of space to cover, then consider renting a pressure washer.

3. Rinse, rinse, rinse. After washing your siding, make sure to do a final, thorough rinse to remove any soap residue.

4. Protect your shrubs. Prepare your area by using drop cloths, plastic, or whatever else may be necessary to protect windows, bushes, foundation, etc.

There are a few acceptable painting methods to paint aluminum siding. First, you can choose to use a spray gun. This is the quickest method, but keep in mind that it uses much more paint than by-hand methods, and applies a thicker coat of paint. We also advise backrolling over the paint with a small foam roller to help enhance adhesion and to create uniformity after spraying.

You could also go straight for a roller or brush. These methods are more time consuming, but you won’t have to worry about overspray or equipment.
