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
Small chips in dolomite are filled with a colour-matched epoxy or knife-grade stone filler, left to cure, then shaved flush and polished. For visible edges and anything larger than a fingernail, a professional repair is much harder to spot. Cracks should always be assessed first.
First, check what you are dealing with
- Small piece missing from an edge or corner: chip.
- Line running across the surface: crack. Have it assessed.
- Hollow sound or movement: possible structural issue.
What you need
- Colour-matched filler or repair kit
- Masking tape
- Single-edge razor blade
- Isopropyl alcohol for cleaning
Step by step
Clean the chip
Clean with isopropyl alcohol and let it dry completely.
Mask around it
Tape around the chip to protect the surrounding surface.
Fill slightly proud
Mix the colour-matched filler and fill the chip slightly higher than the surface.
Cure and shave flush
Once cured, shave the excess flush with a razor blade held flat.
Finish
Polish the repair to match, or have a restorer finish it. A restorer can re-polish dolomite, though it takes more work than marble because the stone is harder.
What not to use on dolomite
- Superglue on visible areas: it yellows and does not match.
- Filling a crack without knowing why it cracked.

Understanding chips and cracks on dolomite
Etches on dolomite tend to start as a faint haze and build into patchy areas around sinks and serving zones.

Good to know
Dolomite is harder than marble and chips less often, but when it does the chip tends to be clean and fills well.
Stop it happening again
Whether yours is Super White and many stones sold as "soft quartzite", repairing it fixes today's mark; protecting it stops the next one. Our clear Stone Protection Film sits over the surface, so acids cannot etch it and liquids cannot soak in. Choose Gloss for polished dolomite or Matte/Satin for honed and matte finishes. The protection is identical. It is installed across Sydney with a 10-year written warranty. It will not stop a heavy knock from chipping an edge, but it protects everything else.
