Prep/Master® Sr. Concrete Floor Grinding Machine (Electric)

Ideal for Polishing Projects up to 5,000 SF (500 M²)

The Prep/Master®Sr. floor grinding machine is designed for medium-sized commercial or residential projects.
This machine combines the production capacity of a larger machine with the maneuverability of a smaller
grinder.

Its 20HP motor has strong torque and its variable speed drive easily adjusts to different grinding or
polishing conditions for concrete, terrazzo, marble, and stone applications.

This grinder is very aggressive, yet extremely easy to operate due to the smooth operation of the STI rotary gear
system. In addition, the low price of the Prep/Master Sr. is very affordable and fits any project budget.
