Quartz countertops are an increasingly popular choice for kitchen and bathroom remodels due to their durability, low maintenance, and stylish appearance. However, like any countertop material, quartz is not completely scratch-proof. Here is what you need to know about scratching quartz countertops.
What is Quartz?
Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The quartz provides strength and durability, while the resins bind the material together.
Compared to natural stone countertops like granite and marble, quartz is more flexible during fabrication, resists staining, and requires very little maintenance. Quartz also comes in a wide variety of colors and patterns to suit any design aesthetic.
Can Quartz Countertops Be Scratched?
While quartz is an extremely durable material, it can become scratched under certain circumstances. Here are the key factors that determine the scratch-resistance of a quartz countertop:
Quartz Hardness
On the Mohs hardness scale, quartz ranks around 7 out of 10, which is on par with granite. This makes quartz more scratch-resistant than materials like marble (3 on the scale) but not as hard as sapphire or diamond (9 to 10 on the scale).
Quartz Density
Higher quality quartz slabs tend to be more dense and impervious to damage. Denser quartz makes it more difficult for sharp objects to penetrate the surface.
Quality of Quartz Resins
The specific resins used by different quartz manufacturers can impact scratch resistance. Higher performing resins create a tighter bond between quartz particles.
Fabrication and Polishing
Precision fabrication and polishing results in an ultra-smooth quartz surface that’s less prone to scratching or etching over time.
So in summary, while quartz won’t scratch as easily as other countertops, it’s not completely invulnerable. The quartz density, resin formula, and fabrication quality all contribute to scratch resistance.
What Can Scratch Quartz?
Quartz won’t scratch under normal daily use. But it can become damaged from:
- Sharp objects – Knives, screws, glass, and metal items can scratch quartz surfaces if dragged across them.
- Abrasive cleaners – Scouring pads, powders, or harsh chemicals degrade the resin binders and scratch the surface over time.
- Extreme impacts – Significant blows from heavy objects may chip quartz or cause hairline scratches.
Scratching is more likely to occur on darker quartz colors and lighter edges or patterns.
How to Prevent Quartz Scratching
While no countertop is completely scratch-proof, you can minimize the risk by:
- Using cutting boards for food prep. Never cut directly on the quartz.
- Choosing non-abrasive cleaners designed for stone surfaces. Avoid bleach or alkaline cleaners.
- Wiping up spills immediately to prevent prolonged exposure to acids.
- Avoiding abrasive pads and powders meant for cooking surfaces.
- Lifting objects to move them, rather than sliding. Apply furniture pads under heavy decor.
- Inspecting quartz edges and seams. New scratches can be professionally buffed and polished.
How to Repair Scratches in Quartz
If scratches do occur in a quartz countertop, there are options:
Light Scratches
For minor surface scratches, use a Scotch-Brite pad or fine-grit sandpaper (400+ grit) and rub in a circular motion. Follow with a stone polish to blend the area.
Deeper Scratches
Significant scratches may require a professional fabricator to sand down and refinish the surface. This eliminates the depressions caused by deeper scratches.
Chip Repair
Chipped areas can be filled with a special quartz filler compound. The material will be colored to match the slab and hardened. Then the fabricator will polish the repaired section.
Seam Repair
Separations at quartz seams and edges can also be re-adhered and buffed by a professional. This prevents moisture and bacteria from penetrating openings.
Quartz Overlay
For extensive damage, a quartz overlay may be needed. This places a fresh layer of quartz over the existing counter. An overlay can restore the appearance and integrity.
While no material is scratch-proof, quartz holds up very well in real-world use. With proper care and occasional maintenance, quartz countertops will remain beautiful for many years. Paying attention to the manufacturer quality, having a smooth fabrication, and preventing impacts can keep your quartz surfaces pristine.
Frequently Asked Questions About Scratching Quartz Countertops
Can you scratch quartz countertops with a knife?
Yes, a sharp knife blade can potentially scratch quartz if you cut directly on the surface. Always use a cutting board for food prep.
What happens if quartz countertops get scratched?
Minor scratches can be buffed out with sandpaper and polish. Deeper scratches may need professional refinishing. Be sure to address any scratches to prevent further damage over time.
Can you scratch quartz with nails?
While unlikely, dragging sharp nails across the surface could potentially scratch quartz. Avoid heavy objects with sharp edges placing pressure on the countertop.
Is quartz or granite more scratch resistant?
Quartz and granite have similar hardness, so both can scratch. But quartz has higher resilience from its resin binders, giving it an advantage in scratch resistance.
Can you scratch quartz with a scouring pad?
Yes, scouring pads and powders will damage the resins over time, causing a scratched appearance. Use a soft cloth or sponge with mild soap and water instead.
Conclusion
Quartz countertops offer unparalleled beauty and durability for kitchens and baths. While they can be prone to scratches from sharp objects, impact, or cleaning abrasives, quartz holds up remarkably well in most homes. With routine care and proper maintenance, quartz countertops will stay looking like new for many years before needing repair or replacement. Pay attention to manufacturer quality, precision fabrication, impact prevention, and cleaning do’s and don’ts to get the most out of your investment. With a scratch-resistant quartz surface, you can enjoy worry-free beauty and convenience for everyday living.
