What is the purpose of using the correct adhesive with tiles?

Using the correct adhesive with tiles is essential to ensure proper tile bonding. Adhesive serves as the medium that holds the tiles securely to the substrate, and its formulation must be compatible with both the tile material and the surface to which the tile is being applied. If the wrong adhesive is used, it can lead to a weak bond, resulting in tiles becoming loose or even detaching from the surface over time. Proper bonding is crucial for the durability and integrity of the installation, as it affects not only the appearance but also the overall performance of the tiled surface under various conditions, including moisture and temperature changes.

While improving aesthetics, increasing tile weight, or speeding up drying time might be considerations in some contexts, they do not address the fundamental function of adhesive, which is to create a strong bond between the tile and substrate.
