Which one is which?
People use "polished concrete" for at least three different floors, and that's where quotes get confusing. Here they are.
| Honed | Polished | Grind and seal | |
|---|---|---|---|
| How far the grinding goes | Smooth, then stops | Right through the fine grits | A grind, then stops |
| Where the look comes from | A sealer over a matte surface | The concrete itself, hardened and polished | A clear coating on top |
| Sheen | Matte | Matte, satin or gloss | Depends on the coating |
| Usual home | Outdoors and wet areas | Living areas, shops, offices | Garages and tighter budgets |
Why does honed go outside and polished stay in?
Grip. A clean, dry polished floor indoors grips fine. Wet is a different matter, and outdoors is wet. Honed concrete is ground smooth enough to be kind on bare feet, then sealed and left matte so there's still something for a foot to hold. That's why it turns up on patios and around pools.
If you want a polished floor in a bathroom, an entry or a shop, ask about slip resistance before you pick a gloss level. It's a question for the polisher, with the room in front of them.
Where does grind and seal fit?
It's the budget cousin. The slab gets one grind and a clear coating, so the shine is in the coating, not the concrete. It looks a lot like a polish on day one. The catch is the coating wears where people walk and needs redoing over time, where a mechanical polish doesn't have a coating to wear.
If a quote for "polished concrete" comes in well under the others, check which of these it's actually for.
Will an older Newcastle slab come up well?
Usually, but it'll show its history. Old glue lines, patches, colour changes and the ghosts of walls that used to be there can all come through.
It's more likely in the older suburbs. City of Newcastle's development control plan dates Cooks Hill's houses from the mid-1800s and Hamilton's from the late Victorian years, and a cottage that's been extended a few times can have concrete from different eras side by side. Each pour polishes a different colour. Ask for a test patch somewhere out of the way before you commit to the whole floor.
Glue and old coatings come off first, which is a job in itself: see concrete grinding and floor prep. Cracks get dealt with before the fine passes too. Our guide on whether to repair or replace cracked concrete covers which ones matter.
Is one cheaper than the other?
Roughly in the order you'd guess. Grind and seal is the least work. Honed is more. A full mechanical polish is the most, because every step up in shine is another pass over the whole floor with finer tooling. Cutting deeper to show more stone adds time to any of them.
We don't publish rates for polishing, because we couldn't find a published figure we'd stand behind. The quote for your floor is the number.
What about the dust?
All three start with grinding, and grinding concrete makes silica dust. SafeWork NSW lists concrete among the materials that contain crystalline silica and says employers must put safety controls in place to protect workers. In a house that also protects you. Ask how the dust will be controlled before anyone starts.
For work worth more than $5,000, look up the contractor's licence with Building Commission NSW as well.
So which one do you want?
- Outside, or anywhere that gets wet: honed.
- Inside, and you want it to last without recoating: polished.
- A garage, a rental or a tight budget: grind and seal, knowing the coating will need redoing.
- Building new and you love the industrial look: talk to your builder about a burnished slab before the pour. It's decided on the day the concrete goes down.
Tell us which one you're after, what's on the slab now and roughly how big it is. We'll send a local polishing specialist to look at it and quote. The full run-through of finishes, stone exposure and the steps is on the polished concrete in Newcastle page.
