What is the term for the type of product designed for use as setting or bonding coats?

Thin set is the correct term for a type of product designed for use as setting or bonding coats in tile installation. Thin set mortar is a cement-based adhesive that is formulated to bond tiles to various surfaces, including cement backer board and other substrates. The application of a thin layer of this mortar allows for a strong bond while maintaining a low profile that is suitable for a variety of tile types and sizes.

Thin set is particularly advantageous because it allows for greater flexibility and adherence in residential and commercial tiling applications. It's designed to create a strong bond while having a reduced thickness, making it ideal for detailed tile work and areas where height constraints are a concern.

In contrast, other terms such as thick set and traditional set refer to different methods or types of mortar that are generally not used in the same way. Thick set methods typically involve using a more substantial layer of mortar, while terms like traditional set may refer to older techniques or variations that do not incorporate the modern standards applied with thin set mortars. Light set is not a commonly recognized term within this context, further indicating that thin set is the widely accepted choice for bonding coats in contemporary tiling practices.
