What is the primary characteristic of dry set mortars?

The primary characteristic of dry set mortars is that they are specifically designed for bonding. Dry set mortars, also known as unmodified thin-set mortars, consist of a blend of cement, sand, and other additives that enhance the mortar's adhesion properties. When applied to flooring or wall substrates, they create a strong bond between the tile and the surface, which is crucial for ensuring that the tiles adhere properly and maintain their position over time.

While it is important to note that dry set mortars typically require mixing with water to activate their bonding properties, the defining feature is their primary purpose of facilitating a strong bond between tiles and substrates. This characteristic is why they are favored in many tiling applications. They can be used effectively for various types of tile installations, including ceramic and porcelain tiles, as long as the correct mixing and installation techniques are followed.
