What is meant by the term "bond strength" in tile installations?

Bond strength refers to the adhesion strength between the tile and the substrate. This is a critical factor in tile installations because it determines how well the tiles will stick to the surface they are being applied to, which affects the durability and longevity of the installation. High bond strength ensures that the tiles remain securely attached during use, preventing issues such as cracking, loosening, or lifting over time.

The other concepts mentioned, such as weight capacity, grout color, and tile thickness, do not relate directly to the adhesion properties of tiles. Weight capacity pertains to how much load a tile can support, which is not a direct measure of how well it adheres to its surface. Grout color is purely aesthetic and does not influence the functional performance of the tile installation. Tile thickness can impact the appearance and structural robustness but does not determine how well the tile bonds to the substrate. Therefore, understanding bond strength is essential for ensuring a successful and resilient tile installation.
