Red Seal Tilesetter Practice Exam

What are the two primary types of tile adhesives?

1. Thin-set and mastic

2. Glue and epoxy

3. Mortar and silicone

4. Foam and acrylic

The correct answer is: Thin-set and mastic

Thin-set and mastic are the two primary types of tile adhesives used in the tilesetting industry. Thin-set adhesive consists of a dry mixture of cementitious materials, sand, and additives that, when mixed with water, provides a strong bond for both floor and wall tiles. It is commonly used for various types of tiles, including ceramic, porcelain, and natural stone, and is valued for its durability and versatility. On the other hand, mastic is a premixed adhesive that usually consists of organic compounds and is often used for wall tiles in areas that are less prone to moisture. It provides a strong bond but is typically not recommended for damp or wet areas. Both types are essential in tilesetting, each serving specific purposes based on the installation requirements and conditions. Understanding the differences between thin-set and mastic is crucial for tilesetters to select the appropriate adhesive for a successful and long-lasting installation, ensuring both adherence and performance under different conditions.
