Level uneven concrete, remove old coatings and prepare floors for new finishes. Sona’s walk-behind concrete surface grinders come in two sizes: the TG330 (330 mm, 4 kW) for rooms and smaller floors, and the TG630 (630 mm, 7.5 kW) for large areas. Built-in dust tank. Tap Get Quote today.
Levelling uneven floors: grind down bumps, ridges and high spots on hardened concrete to give tiles, vinyl or new coatings a flat base.
Removing paint, epoxy and old coatings: strip paint, epoxy, sealers, glue and mastics with the right diamond tooling. Very thick or multi-layer coatings are faster with a scarifier.

Preparing slabs for new flooring: open up and smooth the surface before tiles, vinyl, carpet or coatings, so they bond properly and fail less.
Polishing warehouse and factory floors: move from coarse to fine grits to get a smooth, dust-resistant finish on industrial floors.
Showrooms, malls and commercial floors: cover large areas quickly and evenly. The TG630’s 630 mm width saves time on big floor plates.
Garages, basements and medium rooms: use the compact TG330 for medium floors where a large machine won’t fit or isn’t needed.
Repair and renovation prep: grind damaged areas before crack filling, patching or resurfacing, and refresh worn floors in renovation work.
Terrazzo, marble and stone: refinish hard floor surfaces that need grinding back to a clean, even face.
