Floor Grinding Machines for Sale

Used for marble, terrazzo, stone, and most frequently, on concrete, floor grinders are one of the most commonly used and versatile surface preparation machines. We sell a wide variety of Prep/Master floor grinders, including compact varieties used for small spaces, propelled machines for projects up to 10,000 square feet, and ride-on floor grinders that help you tackle the largest projects quickly while eliminating operator fatigue.

Choosing the Right Floor Grinder

There are several varieties of floor grinders, and choosing the right option can be challenging. The most common option after determining the size you need is choosing an electric or propane model.

Electric floor grinders are ideal for indoor use as they need minimal ventilation and have a much quieter operating volume, making them safe for residential basements, warehouses, and commercial spaces. However, they do need to be plugged into an outlet, which limits your operating space and distance.

Propane floor grinders offer freedom of movement as you simply need to fill the tank. These should be used in very well ventilated spaces due to the fumes produced and noise protection should be used.

Why Choose a Floor Grinder

A floor grinder can be used for numerous tasks, including:

  • Removing existing epoxy or urethane coatings;
  • Leveling uneven surfaces
  • Smoothing pits and cracks in a concrete surface;
  • Mechanically smoothing and polishing concrete to a high-gloss sheen;
  • Grinding away damage and stains;

Rather than having to replace your floors, a floor grinder can restore your surface to its original smooth, glossy appearance.
