Tile adhesive is a type of glue used for fixing tiles onto a surface. It is designed to provide a strong, durable, and long-lasting bond that can withstand exposure to water, heat, and other elements. Tile adhesive comes in various types, including cement-based, epoxy-based, and polymer-based. The choice of adhesive will depend on the type of tile, the surface to be tiled, and the conditions in which the tiled area will be used. It is essential to follow the manufacturer's instructions when using tile adhesive to ensure proper bonding and maximum performance.
