Key features

  1. Thinset Type: Determine the type of thinset mortar you need, such as modified, unmodified, and epoxy-based thinsets.
  2. Coverage/Thickness: Check the coverage and thickness of the thinset mortar, as different applications may require different coverage and thickness.
  3. Tile Size: Choose a thinset appropriate for the size of the tile you are setting, as heavier tiles require more mortar.
  4. Substrate: Determine the substrate for the installation and purchase a thinset designed to bond to that material.
  5. Grades: Consider the grade of thinset you need in order to obtain the desired performance, such as waterproofing or crack resistance.
  6. Mixing: Consider the ease of mixing of the thinset mortar, as some require special equipment or mixing tools.
