Concrete Polishing — Ground, Honed & Diamond-Polished Floors
Polished concrete is the slab itself, refined. We mechanically grind, densify and diamond-polish existing power-floated or new slabs to the sheen level the room needs — from a matt honed finish to a mirror polish.
Where this works
- Retail, showrooms & galleries
- Restaurants & bars
- Warehouse & industrial floors
- Open-plan residential floors
- Commercial receptions & lobbies
How we install it
- 1Grind
Metal-bond diamonds at 30–50 grit open the slab and remove any laitance. Aggregate exposure is decided at this stage: cream (no aggregate), salt-and-pepper, or full aggregate.
- 2Densify
Lithium silicate densifier is applied and worked in — it reacts with the free lime in the slab to harden the wear surface and cut dusting.
- 3Hone & polish
Resin-bond diamonds step up through 100, 200, 400, 800, 1500 and 3000 grit until the target sheen is reached.
- 4Guard & seal
A penetrating stain-guard is applied to protect against wine, oil and traffic marking. Optional impregnating sealer for food-contact areas.
Common pitfalls we prevent
Frequently asked
Can any concrete floor be polished?+
Most slabs 100 mm+ that are power-floated. Aggregate distribution, slab age and cracking are checked first. We take a small test panel to confirm the finish is achievable.
How does polished concrete compare to microcement?+
Polished concrete is the existing slab refined. Microcement is a 2–3 mm skim that goes on top of any sound substrate. Microcement gives more colour and continuity; polished concrete is more industrial and cheaper per m² on a suitable slab.
Is it slippery?+
Polished concrete is naturally around R9–R10 wet. For wet areas we add an invisible micro-etch or aggregate-broadcast top coat.
