Before you try anything: always speak to a professional before cleaning, treating or applying any product to your stone. Every slab is different, and the wrong product can cause permanent damage. Contact us or a qualified stone restorer first.
Quick answer
Scratches on terrazzo are usually in the surface coating first; a specialist re-hones and refinishes the area. There is no product that hides scratches in stone for long: waxes and "scratch fillers" fill them briefly and wear off.
First, check what you are dealing with
- Grey or dark line: may be a metal mark. Try a cream cleaner first.
- Fine white line, smooth to the touch: a light scratch.
- Line that catches a fingernail: a deep scratch needing honing.
What you need
- Non-scratch cream cleaner
- A stone restorer
Step by step
Rule out metal marks
Rub the line with a non-scratch cream cleaner and a damp cloth. Grey lines from pots and cutlery often disappear completely.
Assess depth
Look at the scratch at a low angle and run a fingernail across it.
Book a professional
A terrazzo specialist can re-grind, hone and polish the surface and replace missing chips.
Prevent new ones
Use boards and felt pads under decor, and lift rather than slide heavy items.
What not to use on terrazzo
- Sandpaper and hardware-store abrasives.
- Coloured waxes or "scratch cover" products, which build up and attract dirt.
- Polishing powder on honed terrazzo.
When to call a professional
Call a restorer for scratches you can feel, clusters of scratches on an island or table, and anything on onyx. A terrazzo specialist can re-grind, hone and polish the surface and replace missing chips.
Understanding scratches on terrazzo
Terrazzo mixes materials of different hardness, so scratches often show more in the binder than in the stone chips.
Terrazzo damage shows as dull patches across chips and binder, stained binder, and occasionally loose chips.

Good to know
In terrazzo, scratches show more in the softer binder than in the stone chips.
