What is a substrate in the context of tiling?

  1. The final surface finish of the tile

  2. The decorative edge of the tile

  3. The surface to which tiles are adhered

  4. The adhesive used for installation

The correct answer is: The surface to which tiles are adhered

In the context of tiling, a substrate refers to the surface to which the tiles are adhered. It serves as the foundational layer that supports the tiles and is crucial for ensuring a proper installation. The substrate needs to be stable, clean, and prepared adequately to promote good adhesion and prevent issues such as cracking or mold growth. It can consist of various materials, such as cement board, plywood, concrete, or drywall, depending on the installation area and type of tiles used. Understanding the role of the substrate is essential for tilesetters, as proper preparation of the substrate directly affects the longevity and performance of the tile installation.
