Red Seal Tilesetter Practice Exam 2026 - Free Tilesetter Certification Practice Questions and Study Guide

Removing old grout requires a tool that can efficiently work through the material without damaging the surrounding tiles. A grout saw or oscillating multi-tool is specifically designed for this task, as these tools feature sharp blades or teeth that can precisely cut through grout. The oscillating multi-tool is particularly versatile; it can oscillate back and forth at high speeds, allowing for controlled and precise removal in tight spaces. This minimizes the risk of damaging the adjacent tiles, which can happen with more aggressive tools.

In comparison, a tile cutter is designed for cutting tiles and is not suited for grout removal. A chisel, while it can be used to remove grout, often requires more force, which increases the chances of damaging the surrounding tiles. Similarly, a hammer is not appropriate for grout removal since it is typically used for driving nails or breaking materials, and using it on grout could lead to significant damage. Hence, the grout saw or oscillating multi-tool is the best choice for efficiently and safely removing old grout.
