The short answer is: Yes, terrazzo can scratch, but it is highly resistant to scratching and is considered one of the more durable flooring materials available.
Here's a more detailed breakdown of why and how it can scratch, and what you can do about it.
What Makes Terrazzo Scratch-Resistant?
The incredible durability of terrazzo comes from its composition:
Aggregates: Terrazzo is made by embedding chips of hard materials like marble, quartz, granite, glass, or even mother-of-pearl into a cement or epoxy binder.
The Binder: Modern epoxy and resin binders are extremely hard and durable once cured.
The Finish: Terrazzo is always ground down and polished to a smooth, glossy finish. This process creates a very hard, non-porous surface that is difficult to mar.
How Can Terrazzo Be Scratched?
Despite its toughness, terrazzo is not impervious to damage. Scratching can occur from:
Abrasive Grit and Sand: This is the most common culprit. Sand, dirt, and gritty debris tracked in from outside act like sandpaper. When walked on, these fine, hard particles can grind against the surface and create fine, superficial scratches over time.
Heavy, Sharp Impact: Dragging a heavy, sharp metal object across the floor (like a refrigerator leg, a metal chair leg without a pad, or sharp tools) can absolutely cause a scratch or gouge.
Mohs Hardness Scale: If a material harder than the terrazzo's surface is dragged across it, it will scratch. For example:
Quartz Aggregates: Very hard (~Mohs 7). Can only be scratched by topaz, corundum, or diamond.
Marble Aggregates: Softer (~Mohs 3-4). Can be scratched by harder materials like glass (~Mohs 5.5) or quartz.
The epoxy/resin binder is generally softer than most stone aggregates, so a deep scratch might appear as a light-colored line (the color of the binder) through the pattern of chips.
Prevention and Maintenance
The key to keeping your terrazzo scratch-free is simple maintenance:
Place Mats and Rugs: Use high-quality walk-off mats at all entrances to catch abrasive grit and sand before it gets onto the floor.
Felt Pads are Essential: Attach soft felt pads to the bottom of all furniture legs, chairs, and tables. Check and replace them periodically as they wear down and collect grit.
Regular Cleaning: Frequently sweep, dust mop, or use a vacuum (with a soft brush attachment) to remove loose debris. Never use a vacuum with a beater bar, as this can cause scratches.
Damp Mopping: For deeper cleaning, use a pH-neutral cleaner specifically designed for stone or terrazzo. Avoid acidic or abrasive cleaners.
What to Do If It Gets Scratched?
Light Surface Scratches: Often, these can be polished out by a professional stone and terrazzo restoration company. They have specialized diamond abrasives that can re-hone and re-polish the surface to its original glory.
Deeper Gouges: A professional can often repair a deep scratch or gouge by filling it with a color-matched epoxy and then polishing it seamless.
Quick Summary Table
| Aspect | Answer | Details |
|---|---|---|
| Does it scratch? | Yes, but it's highly resistant. | It's much more resistant than wood, vinyl, or laminate. |
| Main Vulnerability | Abrasive grit and sand. | This is the primary cause of wear and fine scratches. |
| Scratch Prevention | Easy! Use doormats, felt pads, and clean regularly. | Prevention is simple and very effective. |
| Repairability | Excellent. | Professionals can polish out light scratches and fill deeper ones. |
| Compared to Other Floors | More scratch-resistant than most. | More resistant than hardwood, LVP, and laminate. Similar to or slightly less than pure granite or quartz slab. |
Conclusion: Terrazzo is an outstanding choice for high-traffic areas due to its exceptional durability and scratch resistance. With very basic preventative care, your terrazzo floor can remain beautiful and virtually scratch-free for decades.
