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 quartz and Caesarstone are filled with a colour-matched repair resin, often available from the manufacturer, 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 benchtop repairer can fix chips and some surface damage. Because Australia banned new engineered stone in 2024, repairs and protection are how existing tops are kept looking good.
What not to use on quartz
- Superglue on visible areas: it yellows and does not match.
- Filling a crack without knowing why it cracked.

Understanding chips and cracks on quartz
On quartz, damage shows as surface stains, dull or cloudy patches from harsh chemicals, and yellow or brown scorch marks from heat.
