Grout should not be used as a tile adhesive. Grout is a material that is used to fill the gaps between tiles after they have been installed, whereas tile adhesive is used to bond the tiles to the substrate.
While it’s true that both grout and tile adhesive are cement-based materials, they have different properties and are designed for different purposes. Grout is typically a dry, powdery mixture that is mixed with water to form a paste, whereas tile adhesive is a wet, sticky mixture that is applied directly to the substrate.
Using grout as a tile adhesive can result in tiles that are not securely bonded to the substrate and may come loose over time. Additionally, grout is not designed to provide the same level of bonding strength as tile adhesive, and may not be able to withstand the weight and movement of tiles in high-traffic areas.
To ensure a successful tile installation, it’s important to use the appropriate type of adhesive for the specific type of tile and substrate being used. Always follow the manufacturer’s instructions when using tile adhesive, and avoid using grout as a substitute.
