When installing tiles in bathrooms, kitchens, or other wet areas, the surface beneath the tile is critical. A tile backer board acts as a foundation, providing stability, waterproofing, and long-term durability.
Unlike standard drywall, which absorbs moisture and deteriorates over time, backer boards are specifically engineered for wet environments. They ensure your tiles adhere properly, protect the structure behind them, and prevent costly water damage.
The main types of tile backer boards available today are cement boards, foam boards, and waterproof membranes. Each option has unique strengths and considerations.
