Concrete Floor Grinders

Concrete Floor Grinders

Grind and polish concrete with the right machine for the job. We're the makers of the Prep/Master® grinder, and we carry the floor grinders that prep, level, and polish concrete — from planetary machines to hand grinders. Whatever you run, we'll help you choose and keep it running. Call and talk to a real surface-prep expert, not a call center.

Concrete Floor Grinders

  • Prep/Master® grinders — our own gear-to-gear concrete grinders and polishers, built to last and available in a range of sizes
  • Planetary grinders — Lavina® and more, for grinding and polishing larger floors
  • Hand grinders & edgers — for edges, tight spaces, and detail work

Grinding to Polishing — One Machine Range

A good floor grinder takes you from aggressive grinding through fine polishing. Match the machine to your floor size and finish: a planetary for open areas, the Prep/Master for prep-to-polish versatility, and hand grinders for the edges and spots the big machines can't reach.
