What is the main purpose of a backer board in tiling?

• A. To enhance color of tiles
• B. To provide a stable base and prevent cracks in the tile
• C. To help with aesthetic design
• D. To insulate the tiled area

Answer: (B)

The main purpose of a backer board in tiling is to provide a stable base and prevent cracks in the tile. Backer boards, often made from materials like cement or foam, add stability to the surface where tiles will be installed. They create a level, waterproof surface that can handle moisture and the weight of the tiles. This is particularly important in wet areas, such as bathrooms or kitchens, where movement and moisture can lead to cracks in the tile if proper support is not provided. By using a backer board, tilers ensure that the underlying surface helps distribute the stress that tiles may undergo from foot traffic, temperature changes, or other factors. This function significantly reduces the risk of tile cracking or becoming loose over time, enhancing the durability and longevity of the tiled surface.
