An exterior cement board is a type of siding product used to cover and protect exterior walls. One of the primary reasons people use cement board on exterior walls is because of its durability and ability to stand up to the wear and tear of harsh conditions.
Another advantage of using exterior cement board is that it is resistant to water damage and inhibits mold and mildew growth. Decorating exterior cement board is also easy, with paint and stucco being common finishes. In addition to exterior walls, cement board can also be used on fencing, mobile home skirting and garage wainscoting. It is easy to cut and installs quickly.
