What does the term “thin-set” refer to?

The term “thin-set” specifically refers to a type of adhesive mortar commonly used in tile installation. It is a cement-based product that is mixed with water or a latex additive to create a paste, which is then applied in a thin layer (typically 1/8 inch or less) to bond tiles to substrates such as concrete, cement backer board, or drywall. This method allows for a stronger and more flexible bond, which is essential for the longevity of the tile installation. Thin-set mortars are versatile and can be used for a variety of tile types, including ceramic, porcelain, and stone, making them an essential component in the tiling process.

In contrast, decorative tiles pertain to the aesthetic aspect of tiling rather than the materials used, while a method of laying tiles refers to installation techniques rather than the adhesive itself. A brand of grout would also not relate to thin-set, as grout is used to fill the joints between tiles after they are installed, serving a different purpose in tile work. Thus, the definition and application of “thin-set” highlight its crucial role in ensuring that tiles are securely attached to their base.
