It is often more cost-effective to repaint old aluminum siding than to replace it. It’s normally a straightforward process, as long as you get the preparation process right and use the right painting materials. So if your aluminum siding is showing signs of paint peeling, chipping and flaking, the tips in this article will guide you on how to repaint it.
As always, we strongly recommend that you hire a qualified professional painting contractor if you don’t have the basic residential painting training and experience.
Tips for Repainting Aluminum Siding
Paint generally needs to dry slowly in order to properly bond with the painted surface. You should preferably paint at a time when the weather is going to be overcast and dry. For instance, early Fall makes for the best painting time in Clinton Township, MI and other surrounding towns.
2) Don’t Pressure Wash, Unless…
The siding needs to be thoroughly cleaned before repainting. Painting over dirt and dust often creates room for premature paint failure and a poor quality repaint job from the start. While power washing is the easiest way to clean your aluminum siding, if you don’t know how to handle it, you can easily get water behind the siding which then leaks in your house.
The safer option is to clean your siding using a mild detergent and a large sponge. If you have to use a pressure washer, angle the pray in the direction rain would hit the house as washing from the bottom up can cause unnecessary damage to the siding and the said water leakage.
3) Sand thoroughly
Sanding the siding helps to get rid of the loose, flaking and peeling paint that could easily ruin your results if you painted over it. Now, this is where you really need some elbow grease and patience –it’s quite a painstaking task, but it’s worth it. You will get better results and work faster if you sand using an electric sander.
4) Don’t Skip the Primer
Painting aluminum or any other metal material for that matter can be a little tricky –paint generally does not stick well to metal surfaces. Applying a primer as the first coat evens out the surface and makes it suitable for paint adherence. Use a thinned oil-based metal primer, don’t use a latex primer.
5) Choose the Paint
Acrylic exterior grade paints are typically the best when it comes to painting aluminum, and you can find paints specifically designed for painting aluminum if you look hard enough. Acrylics hold up better throughout all the seasons and are least likely to fade. Opt for eggshell or satin finishes as opposed to high-gloss paints which tend to reflect the sun’s glare.
6) Choose Your Painting Method
The idea here is to use a method that you’re familiar with. So while an airless sprayer might be an efficient and the easiest equipment to use, if you’ve never used it before, opt for a roller or brush. Additionally, an airless sprayer might be a little more costly compared to using a roller or brush. For many DIY enthusiasts, a roller makes for a happy middle ground between the cheaper but slower paintbrush and the faster but more expensive airless sprayer.
The Bottom Line
Repainting an aluminum siding isn’t that complicated. But as earlier mentioned, you need some training and painting experience, as well as the right tools to successfully complete this project; otherwise, hiring a professional painter might be your best option.
