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 porcelain are filled with a colour-matched resin, applied by a porcelain repairer, left to cure, then shaved flush and finished. 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
A repairer will blend the colour and texture to the surrounding print.
What not to use on porcelain
- Superglue on visible areas: it yellows and does not match.
- Filling a crack without knowing why it cracked.
When to call a professional
Get a professional for sink cut-outs, visible edges, anything larger than a fingernail and any crack. A porcelain repairer can fill chips with colour-matched resin; scratches through the printed layer cannot be polished back.
Understanding chips and cracks on porcelain
Porcelain problems are usually residue, metal marks, chips on edges, or scratches through a polished glaze.
A porcelain repairer can fill chips with colour-matched resin; scratches through the printed layer cannot be polished back.
Good to know
Porcelain chips reveal the plain body under the printed surface. A good repairer can colour-match the fill, but the printed pattern is very hard to recreate.
Stop it happening again
Whether yours is large-format marble-look and concrete-look porcelain slabs, repairing it fixes today's mark; protecting it stops the next one.

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.
