Which tool is the primary tool for applying mortars and adhesive?

• A. Tile cutter
• B. Tile saw
• C. Grout
• D. Notched trowel

Answer: (D)

The main idea is that the notched trowel is used to apply mortars and adhesives in a way that guarantees proper bond and coverage. The notches create uniform ridges of adhesive on the substrate (or on the tile), which, when the tile is pressed into place, collapse and spread to fill gaps and ensure full contact between the tile and the mortar. This thin, even layer with the right thickness is essential for a strong, durable bond and to avoid voids under the tile. The notch size is chosen based on the tile size and the type of adhesive, so you use a smaller notch for smaller tiles and a larger notch for bigger tiles or heavier installations. After spreading, you press the tile firmly (often with a slight twist) to bed it into the adhesive.

Tile cutters and tile saws are used for cutting tiles to fit edges and obstacles, while grout is applied later to fill the joints between tiles after the adhesive has cured.
