Repairing a chip in a quartz worktop is a skilled process that requires the right materials and technique. Here is exactly how a professional repair is carried out — and why the DIY approach rarely achieves the same result.

The Professional Repair Process

Step 1 — Assessment
The technician assesses the chip — its size, depth, location and proximity to other features such as the sink or hob. The colour and pattern of the quartz around the chip is observed carefully in natural light.
Step 2 — Colour matching
A colour-matched resin compound is selected from the technician’s library and adjusted with pigments until it matches the specific colour and aggregate character of the quartz at the chip location. A test patch is applied and checked after curing.
Step 3 — Preparation
The chip is cleaned thoroughly to remove any grease, dust or loose material. The edges of the chip are prepared to give the repair compound a clean bond surface.
Step 4 — Application
The compound is applied in layers — building up slowly to avoid shrinkage. Each layer is allowed to partially cure before the next is applied.
Step 5 — Shaping
Once fully cured, the repair is shaped flush with the surrounding surface using graded abrasives.
Step 6 — Polishing
The repair is polished progressively to match the gloss level of the surrounding quartz.

Why DIY Kits Rarely Work on Quartz

Quartz comes in hundreds of colours. DIY kits offer a limited range. The mismatch between the kit colour and the specific quartz colour is almost always visible.
