A polished marble floor, free of surface scratching — a Singapore home
Because polished marble's shine is the surface finish itself, any scratch that cuts into that surface removes the gloss right where it cuts — which is why even a fine scratch on marble is far more visible than the same mark on a duller floor.
What causes scratching
- Grit tracked in on shoes — sand and small stones act like sandpaper under foot traffic
- Dragged furniture — moving chairs, tables or appliances without lifting them
- Pet claws — especially on larger or more active dogs
- The wrong cleaning tools or products — abrasive scrub pads or non-pH-neutral cleaners that slowly dull the finish with every use
Shallow vs. deep scratches
Very fine, shallow surface scratches can sometimes be honed out with a fine-grit diamond pad and re-polished without needing a full grind. Deeper scratches — the kind you can feel with a fingernail — need coarser diamond grinding first to level the surrounding surface evenly, otherwise honing alone leaves a visible dip where the scratch was.
Why DIY scratch repair often makes things worse
Consumer marble polish and buffing pads can improve very light surface dulling, but they can't remove material the way a diamond grinding disc does. Using the wrong grit, or trying to spot-treat just the scratched area, often leaves a patch with a different sheen level to the surrounding floor — more noticeable than the original scratch.
Preventing future scratches
Use felt pads under furniture legs, a doormat at entrances to catch grit before it reaches the marble, and trim pets' nails regularly. None of this eliminates the need for periodic re-polishing on a well-used floor, but it slows how quickly the shine wears down.
