CTI Tools & Equipment Flashcards

Which type of trowel is most commonly used to apply thin-set mortar for large-format tiles?

Answer: Square-notch trowel

A square-notch trowel is recommended for large-format tiles because it provides maximum mortar coverage.

What is the primary purpose of a rubber mallet in tile installation?

Answer: Embedding tiles firmly into mortar without cracking them

A rubber mallet gently seats tiles into the mortar bed without the impact force that would crack the tile.

Which saw is best suited for cutting curves and irregular shapes in ceramic tile?

Answer: Rotary tool with diamond bit

A rotary tool fitted with a diamond bit allows freehand curved cuts that straight-blade saws cannot make.

What does a tile lippage leveling system primarily help prevent?

Answer: Uneven tile edges that create height differences between adjacent tiles

Lippage systems use clips and wedges to hold adjacent tiles flush while the mortar cures, eliminating height differences.

When should a diamond blade wet saw be used instead of a score-and-snap cutter?

Answer: For porcelain or stone tiles that are too hard or thick to snap cleanly

Dense porcelain and natural stone require a diamond wet saw because the score-and-snap method causes irregular breaks in hard materials.

What is the correct way to check for hollow spots under an installed tile?

Answer: Use a wooden or metal sounding tool and tap lightly across the surface

Sounding (tapping) with a mallet or special tool produces a hollow ring where mortar contact is insufficient.
