CTI Tools & Equipment Flashcards

What is the main advantage of an angle grinder with a diamond cup wheel over a standard wet saw for tile work?

Answer: It can grind down high spots and lippage on installed tiles

An angle grinder with a diamond cup wheel can remove high spots on installed tile surfaces or rough-cut natural stone edges.

Which mixing paddle attachment is recommended for mixing thin-set mortar to avoid introducing excess air?

Answer: Jiffy mixer or potato-style paddle at low speed (300 RPM)

A slow-speed Jiffy-style paddle mixes mortar thoroughly without whipping in air bubbles that weaken the final bond.

Why must a wet saw blade be continuously supplied with water during cutting?

Answer: To cool the blade and suppress silica dust

Water cools the diamond blade to prevent overheating and also suppresses airborne silica dust, a serious respiratory hazard.

What tool is used to ensure proper spacing and consistent grout joint width between tiles?

Answer: Tile spacers

Tile spacers are plastic crosses or wedges placed at tile corners to maintain uniform grout joint width throughout the installation.

Which hand tool is used to clean excess mortar from grout joints before it fully cures?

Answer: Margin trowel or utility knife

A margin trowel or utility knife scrapes out excess mortar from joints while it is still workable, preparing them for grouting.

What does a digital angle finder help a tile installer determine?

Answer: The exact degree of out-of-plumb walls so cuts can be made to compensate

A digital angle finder measures the precise angle of a wall or floor corner so the installer can make compensating bevel cuts for a tight fit.
