The words “scratch” and “chip” are often used interchangeably when customers describe surface damage — but they refer to quite different types of damage that require different repair approaches. Understanding which you have, and how it affects repairability and cost, helps set accurate expectations before booking a professional assessment.
What Is a Chip?
A chip is a loss of material — a piece of the surface has broken away, leaving a void or depression in the surface. Chips typically occur from sharp impact: a heavy pan dropped on a worktop, a bottle falling in a bath, a tile corner struck by a trolley wheel. The chip may be small (a few millimetres) or larger (several centimetres of edge material broken away). Chips in hard surfaces like stone, ceramic and quartz tend to have a distinct concave shape at the damage point.
Chip repair involves filling the void with a compatible, colour-matched compound that bonds to the substrate and is finished flush with the surrounding surface. The repair compound replaces the lost material.
What Is a Scratch?
A scratch is a surface-level mark where material has been displaced or the surface coating damaged, but without significant loss of bulk material. Scratches are caused by sliding contact — dragging cutlery across a worktop, a pan base on a tile, a zip or metal object across a bath surface. The depth matters: surface scratches that have only affected the topmost coating or polish layer behave very differently from deep scratches that have cut into the material body.
How Scratch Repair Works
For surface-level scratches on polishable materials (quartz, granite, solid surface, acrylic baths), the repair approach is sanding back the surface around the scratch and re-polishing to blend the repair area with the surrounding finish. This approach removes material from the surrounding surface to bring it level with the scratch, rather than filling the scratch itself.
For deeper scratches into the material body, or on non-polishable surfaces (ceramic tiles, laminate), a fill-and-finish approach similar to chip repair is used.
Key Differences for Repairability
- Size matters more for chips — a small chip repairs very cleanly; a very large chip with significant material loss is more challenging. For scratches, depth matters more than length.
- Location matters for both — scratches and chips in flat field areas repair more easily than those at corners, joins or highly visible front edges.
- Multiple scratches in a concentrated area — widespread fine scratching (sometimes called micro-scratching or surface hazing) can sometimes be polished out in one operation; individual isolated deep scratches are typically filled or spot-polished.
