Grind It Polished Concrete Floors

What is mechanically polished concrete?

Polishing concrete is a lot like sanding timber, just with much heavier machinery. We grind with coarse diamonds to expose as much (or as little) stone as you want, apply a liquid hardener (densifier) that hardens the concrete from the inside, then polish through progressively finer grits to your chosen sheen. With no thick topcoat, there's nothing to peel or flake off – that's the big difference from grind and seal.

Where does it suit?

Polished concrete suits living areas and kitchens in new builds and renovations, garages and display homes, shops, salons, barbers, cafés, offices and showrooms, and features like BBQ bench tops.It's best suited indoors. For pool surrounds, patios and paths we'd usually recommend a honed finish – see our Honed & Exposed Aggregate page.

What is grind and seal?

Grind and seal is a two-part process. First, we grind the concrete with diamond tooling to open up the surface and expose the aggregate to your chosen level. Then we seal it. Mechanical polishing gets its shine from grinding and polishing through many grits; grind and seal gets its shine from the sealer. With fewer grinding stages, it takes less time and usually costs less.

What is honed concrete?

Honed concrete is ground and smoothed, but not polished to a gloss. It has a satin to matt look and reflects much less light than polished concrete. It also tends to look a little lighter in colour. Because the surface isn't glassy, it's a better choice for outdoor and wet areas.Exposed aggregate, the way we do it, means grinding the top of the slab off to show the stones inside the concrete.
