Fiber-cement siding is applied to the exterior of buildings to protect them from the elements. This product comes in a wide range of colors and styles that resemble conventional siding materials, notably stucco, cedar shingles, and wood clapboards. It’s made primarily from cement, sand, and wood fiber (often a recycled wood-fiber waste product), a combination that results in an extremely durable material. Fiber-cement planks made with a wood-grained or a smooth finish are popular. These come in widths of 4 to 12 inches, so you can match existing siding if you’re building an addition or garage.
Fiber-cement siding can be primed and painted at the factory or on the building site. If you want to change the color at a later date, no problem. Water-based acrylic paints adhere well. And fiber-cement siding does not expand and contract as much as wood siding, so paint stays in place better. It rarely peels or blisters, reducing maintenance time and cost.
