Etch, lippage, or a crack
Toilet cleaner and citrus leave a dull ring. That is etch, not a stain you can mop off. Honing takes the ring back. A crack is a fill, then a grind.

|---|---|---|
| White rings on a bathroom curb | Acid cleaner etched the polish | Spot hone and seal 1 to 3 sqm: S$280 to S$480 |
| Dining table looks cloudy | Etch plus a spilled stain | Poultice and recrystallisation: S$320 to S$580 |

| Living room lippage and dull grout | Wear across the field | Grind, colour-match grout and crystallise 20 to 50 sqm: S$750 to S$2,200 |

A buff between diamond grinds
Acid-etch removal, crack repair and diamond polishing: access and preparation
Acid-etch removal, crack repair and diamond polishing is a repair of the floor that is already down, unless the brief is a full hack and a new build-up. A loose parquet strip, a stained grout joint, a chip in a stone edge, or a vinyl plank that has peaked can be a contained visit. Hacking tiles out of an HDB bathroom is a renovation permit, and many new BTO bathrooms cannot be hacked in the first three years.
Area, whether a spare tile exists, and whether the stone is marble or a ceramic all change the method. Condo rules often cover slurry, lift padding and working hours. Landed stairs and outdoor stone add weather and a longer cure.
- Daylight photo with a scale
- Say if the patch is wet today
- Name the material if you know it
- Keep the room empty if a polish is booked
- Mention a BTO key-collection year if the bathroom is new
Plan Acid-etch removal, crack repair and diamond polishing
Find out whether water is still arriving before any finish goes on.
Match the material. Acid that is safe on a ceramic bowl is not safe on marble.
Repair the patch. Do not sand a whole flat because one strip is black.
Let the finish cure before furniture goes back.

| Access | HDB | Condo | Landed |
|---|---|---|---|
| Hacking | HDB permit, and a BTO may ban bathroom hacking for three years. | MCST deposit and a rule on slurry in the common stack. | No HDB permit. Structural slabs and outdoor falls still need a proper build-up. |
| Material | Vinyl, tile and parquet are different tools. | The same materials, often with a management ban on dry cutting. | Stone landings and pool decks are not an indoor polish. |
| Moisture | Stop the leak before the finish. | A neighbour’s stack can be the source. Do not coat over it. | Ground moisture in a landed slab is a different diagnosis from a spill. |
