When homeowners ask for “marble polishing,” they can mean two very different jobs. A quick buff brings back some shine. Diamond grinding resurfaces the stone. Choosing the wrong one wastes money, or leaves you with a floor that still looks tired.
What buffing does
Buffing uses a machine with polishing pads, and often a polishing powder or crystallising compound, to restore gloss to the top layer of the stone.
Good for:
- Floors that are slightly dull from daily foot traffic
- Light surface haze
- Regular maintenance between deeper restorations
Limits: buffing doesn’t remove scratches, etch marks or uneven tiles. It adds shine on top of them.
What diamond grinding does
Diamond grinding uses a series of diamond pads, from coarse to very fine. The coarse pads remove a thin layer of damaged stone. The finer pads smooth it out, and the final stages bring up a deep, natural shine.
Good for:
- Visible scratches, chips and etch marks
- Uneven tiles where edges stick up (lippage)
- Old floors where joints have been filled with marble gum
- Terrazzo and granite floors that have lost their finish
The result is a flat, even floor with a consistent shine from wall to wall.
Side by side
| Buffing | Diamond grinding | |
|---|---|---|
| What it fixes | Light dullness | Scratches, etches, uneven tiles |
| How deep it goes | Surface only | Removes a thin damaged layer |
| Time needed | Usually quick | Longer, often a few days for a whole home |
| How long the result lasts | Shorter | Much longer |
| Best used | As regular maintenance | For full restoration |
Which one do you need?
Run your hand and your eye across the floor:
- Shine is just a bit faded, no scratches you can feel: buffing is enough.
- Scratches catch the light, dull patches, or tile edges you can feel: you need diamond grinding.
- Moving into an older resale HDB or condo: grinding before you move in is usually worth it, while the home is empty.
Keeping the shine afterwards
- Use doormats at entrances to trap grit, which scratches marble like sandpaper
- Sweep or vacuum before mopping
- Mop with a pH-neutral stone cleaner
- Put felt pads under chair and table legs
- Book a light buff periodically so the floor never gets to the point of needing heavy grinding
