  • What is cement board?

    Cement board – also known as backerboard – is specially designed for use in place of drywall behind tile in the wet areas in bathrooms and kitchens. It’s hard, durable, naturally moisture- and mold-resistant, and won’t rot, disintegrate or swell when exposed to water. It’s ideal for use behind tile in showers, tubs, backsplashes and countertops, and behind exterior finishes such as thin brick, stucco and manufactured stone.
