Concrete Grinding
Grinding (also called honing) is the first step, where the surface is mechanically removed. This step is normally done 10 – 20 days after the concrete is laid but can be done at any time on older existing concrete. This process exposes the aggregate (stones) in the concrete, although it is possible to polish the surface without revealing any aggregate. The standard concrete aggregate can be supplemented with other materials such as glass and shell when it is being laid, which are then revealed with grinding. The deeper the grind, the more aggregate is visible. The depths of grinding are described as follows:
Natural Polish – 0 mm of the surface removed
Salt and Pepper grind – 1-2 mm of the surface removed
Light grind – 2-3 mm of the surface removed
Medium grind – 3-4 mm of the surface removed
Heavy grind – 5+ mm of the surface removed
Natural Polish – 0 mm of the surface removed
Salt and Pepper grind – 1-2 mm of the surface removed
Light grind – 2-3 mm of the surface removed
Medium grind – 3-4 mm of the surface removed
Heavy grind – 5+ mm of the surface removed
Concrete Polishing
The second step is the polishing of the concrete, where the surface is made smoother by passing over the floor multiple times with increasingly finer pads. If you think of different grades of sandpaper, you start with the rough and work your way to a smoother grade to finish. With polishing, 100 grit gives a rough floor, and you can go up to 3,000 grit which gives a mirror finish.
While a floor that has simply been ground can be sealed, a true polished floor is treated with a densifier which hardens the concrete, then a microfilm is burnished into the surface after polishing – this process is the PeterFell C2 Polished Concrete System.

Concrete Texturing
A process called Bush Hammering utilising specialised tooling is used to texture the concrete surface. This creates an even non-slip texture and enhances the concretes appearance. Because it’s an integral part of the concrete, the texture will last, ensuring your surface remains safe and slip-free for generations.
