Proper Installation
The first preventative measure is proper installation. Due to the nature of fiber cement – it’s heavy and hard to cut – you want to take care to follow proper steps. This type of siding is susceptible to moisture damage, so it’s super important to properly fasten, gap, and seal.
Caulking
Caulking is also another important factor. Obviously, it’s crucial to adequately caulk during installation. But as time goes by, you’ll also want to keep an eye on the condition of the caulking. Part of the repainting process should also include re-caulking, but you don’t want to wait until your next recoating to inspect your sealant.
Use the Right Paint
Another tip is to use proper paint. When recoating, go with one that is UV resistant. This will protect your siding from unnecessary fading. Also, choose an acrylic latex paint that’s formulated for exterior use. For the smoothest application, use a paint sprayer. This helps big time, especially when there’s a lot of texture.
Routine Cleaning
Finally, routine cleaning is a fantastic way to keep your siding shiny and safe. From chalking to mold to grime, an annual clean will do wonders. You can either use a garden hose (in conjunction with a scrub brush) or a power washer to get the job done. With particularly stubborn spots, hit them with a brush.

Repairing Loose Panels
