Cement Board

Cement board is a durable, water‑resistant panel used as a base for tile, stone, or other finishes in wet or high‑moisture areas. It’s commonly used in bathrooms, kitchens, and exterior applications as an alternative to drywall or plywood because it does not rot, swell, or mold when exposed to water.

Structure & Composition

• Core: Cementitious material (Portland cement mixed with sand or fiberglass)

• Reinforcement: Fiberglass mesh or cellulose fibers embedded in the board for strength

• Surface: Smooth or textured to allow tile adhesive to bond effectively

• Edges: Square or beveled edges for easy installation and joint treatment

Cement boards typically come in sheets that are rigid and stable, making them ideal for tiling and flooring.
