Concrete Floor Grinders for Surface Preparation and Repair

A floor grinder resets a slab before anything new goes on top of it, stripping coatings, leveling high spots, and opening the pores of the concrete so a coating or overlay actually bonds. This lineup runs from single head units built for edges and detail work to planetary grinders that carry several rotating discs at once and cover open floor space much faster.

Head count is what separates the two styles. A single head machine is simpler to maneuver and cheaper to own, which makes it a natural fit for tight areas, stairs, and touch-up passes. A planetary machine spreads the workload across multiple satellite discs that pivot independently, so it tracks the floor's contour and clears large square footage in fewer passes, though it comes at a higher upfront cost. Shot blasters take a different route entirely, firing steel shot at the surface instead of grinding it, which profiles concrete fast without dust or slurry.

Husqvarna and Hawk Enterprises anchor the grinder selection, spanning both single head and planetary machines. Diteq and Edco add more grinders along with scrubbers and specialty equipment. Pearl Abrasive and National Flooring Equipment round out the grinder and shot blaster options. Bartell, Rokamat, Trelawny, SealBoss, Northrock, and Eibenstock fill in the remaining scrubbers, repair products, and smaller equipment.
