How to Use an Angle Grinder to Remove Thinset


Using power tools greatly increases a worker's efficiency. Tasks that take hours to complete by hand may be accomplished in much less time by a worker with an electric or pneumatic tool. Removing Thinset by hand requires chipping it away with a hammer and chisel. This can be a laborious, time-consuming process when cleaning a large area. Removing Thinset with an angle grinder requires neither special skill nor strength, and workers comfortable using power tools can quickly learn the required technique.

Things You'll Need

  • Abrasive grinding disk
  • Brush
  • Install an abrasive grinding disk if one is not already attached to the grinder: Grinders vary by manufacturer, so consult your owner's manual for instructions on installing a disk.

  • Turn on the grinder and grasp it with one hand on the handle and the other hand on the body of the grinder.

  • Hold the grind wheel against the surface you want to clean and move the grinder slowly across it as the grinding wheel sands away the Thinset: Don't press the grinder or you might damage your surface. Turn off the grinder and set it aside after you have cleared the Thinset away.

  • Brush off any dust left by the Thinset.

Tips & Warnings

  • Wear protective goggles when removing Thinset.
