Now almost no manufacturers produce hardboard siding, but you might still encounter it on 1960s- through 1990s-era homes. If your home has this siding, you can keep it in good condition with vigilance and consistent maintenance.

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.

Steps To Repair Cracked Fiber Cement Siding

Repairing Loose Panels

When dealing with loose panels, the most common issue is that a nail or multiple nails are not sunk into a stud. The easiest fix is to nail the piece back into place, making sure it goes into a stud. When there’s no stud available behind the siding, a technique called ‘pinning back’ can be applied.
