Quartz countertops have become an increasingly popular choice for kitchen and bathroom remodels in recent years. Known for their stylish appearance and durability, quartz countertops are touted as a practical and long-lasting option. But just how durable are quartz countertops? Here is a complete guide on the durability and longevity of quartz countertops.
What is Quartz?
Quartz is a man-made material created from natural quartz crystals and resins. Quartz countertops are made by combining approximately 90% ground natural quartz with about 10% resins, polymers, and pigments. This combination creates a robust engineered stone that is hard, non-porous, and visually appealing.
The resins bind the quartz particles together forming a durable, solid surface. The pigments introduce color and pattern variation mimicking the look of natural stone. Unlike natural stone, which can be inconsistent in color and pattern, quartz offers dependable uniformity. This manufactured composition is what gives quartz its renowned resilience.
How Durable is Quartz?
With proper care and maintenance, quartz countertops can last for many years looking as gorgeous as the day they were installed. Here are some of the factors that contribute to the durability of quartz:
Hardness
Quartz has a Mohs hardness rating of 7 out of 10. This means it is extremely scratch resistant and ranks just under diamonds in hardness. Quartz won’t scratch, scuff or mark easily. This hardness makes it very durable for kitchens and bathrooms which see a lot of use and abuse.
Non-Porous
Unlike natural stone, quartz does not absorb liquids. The resin binds the quartz particles to create a surface that is impervious to liquids. This non-porous quality makes quartz resistant to stains caused by wine, coffee, juice, oil or other kitchen mishaps.
Heat Resistance
Quartz is more heat resistant than other countertop materials such as solid surface, laminate, wood or marble. Brief accidental contact with hot pots or baking sheets up to about 150°C will not damage quartz. However, it is still important to use trivets and hot pads to protect the surface.
Impact Resistance
Quartz is remarkably tough under impact. Dropping heavy objects, appliances or cookware is unlikely to chip, crack or scratch quartz. Minor nicks or dings can be sanded and polished out by a professional.
Acid Resistance
Quartz has excellent resistance to acids. Splashing vinegar, lemon juice or wine will not etch or stain the surface. However, prolonged exposure to strong chemicals can damage the finish.
Stain Resistance
The non-porous quality of quartz makes it impervious to stains. It can be cleaned easily if stained by oil, grease, food, ink or dyes. But some stubborn stains may require professional help.
Mold/Mildew Resistance
Quartz resists mold, mildew and bacteria growth because of its non-porous nature. Its hard surface does not allow spores to penetrate and spread.
Flexural Strength
Quartz has high flexural strength, meaning it has excellent load-bearing capacity. It can withstand the weight of heavy objects without cracking or chipping. This makes it suitable for high traffic areas.
Hygienic
The integral polymers make quartz antimicrobial and hygienic. This attribute makes quartz popular for hospitals, clinics and laboratories that require sterile surfaces.
With this impressive range of properties, quartz countertops are clearly an extremely durable and resilient choice for kitchens, baths, hospitals, laboratories and more.
How Long Do Quartz Countertops Last?
With proper installation and care, quartz countertops can easily last 25 years or longer. Many manufacturers offer a 10 year to lifetime limited warranty which speaks to the expected longevity of quartz. Here are some factors that determine the lifespan of quartz:
Quality of Quartz
Higher priced quartz made from premium imported quartz and top-grade resins will generally last longer than discounted, low-priced quartz options. Reputable brands use the choicest raw materials and rigorous quality control.
Skilled Installation
Proper installation by an experienced professional ensures tight seams and prevents moisture intrusion that can damage quartz. Poor installation can shorten lifespan.
Maintenance
Following the manufacturer’s care and cleaning instructions keeps quartz looking new for years. Promptly cleaning up spills prevents staining. Annual sealing helps boost stain resistance.
Usage Level
How the quartz is used impacts its longevity. Countertops in lightly used guest bathrooms will last longer than heavily used kitchen counters seeing daily use. Commercial use shortens the lifespan more than residential use.
Exposure to Heat
Excessive direct high heat exposure can damage quartz over time. Using trivets and taking care to prevent extreme heat exposure preserves longevity.
Impact Damage
Quartz’s hard surface resists chipping and cracking well. But excessive force and impact, for example from heavy appliances being dropped, could damage quartz. Minor damages can be repaired to restore appearance.
Sun Exposure
Prolonged sun exposure can cause quartz to fade or discolor slowly over time. Sealing yearly helps maintain color.
With proper care, even heavily used residential quartz countertops should serve well past a decade. For commercial settings or surfaces seeing extreme use, warranties of 10 to 15 years are commonly provided.
How to Care for Quartz Countertops
Caring for quartz properly is important to maintain its durability and beauty. Here are some quartz care tips:
- Clean frequently with a mild soap and water. For stubborn stains use a non-abrasive cleaner designed for stone.
- Though relatively heat resistant, always use trivets or hot pads when placing hot objects on quartz.
- Never cut directly on a quartz countertop. Use a cutting board.
- Wipe up spills immediately before they have a chance to stain.
- Avoid abrasive cleaners, scouring pads, and acidic or alkaline cleaners which can scratch and dull the surface.
- Reseal quartz countertops annually using a penetrating sealer to reinforce stain protection.
- Inspect quartz regularly for any cracks or damage and get repairs done promptly.
- For heavy use areas consider applying a quartz color enhancer regularly to keep the surface looking like new.
Signs of Damage to Look Out For
Quartz is impressively durable, but it is possible to damage it if abused excessively. Here are some signs of quartz damage to look out for:
- Cracks and chips from excessive impact.
- Surface scratches from heavy abrasion or use of scouring pads.
- Discoloration or blistering from prolonged direct high heat exposure.
- Lightcolored blotches from chemical exposure.
- Loss of shine and polish from lack of resealing over time.
- Stained areas that fail to clean up indicating deep staining.
- Visible seams or moisture damage from poor installation or water leaks.
- Fading or yellowing from excessive sun exposure.
Can Quartz Countertops Be Repaired?
In case of damage, quartz countertops may be repairable in some cases. Here are some options:
- Scratches – Minor scratches can be buffed and sanded out by professionals. Deeper gouges are harder to remove.
- Chips – Small chips can be smoothed over but visibility may remain. Larger chips are difficult to repair seamlessly.
- Cracks – Cracks cannot be repaired in quartz. The damaged section needs replacement.
- Burn marks – Discoloration from heat may be permanent. Resurfacing provides some improvement.
- Stains – Most stains can be removed with the right cleaners. If stains persist, quartz can be resurfaced.
- Fading/discoloration – Color enhancers help improve faded areas. Severe discoloration requires replacement.
The repairability depends on the type and extent of damage. Severe damage like cracks may require a full slab replacement. Minor scratches can be buffed out. It is best to contact a professional fabricator to evaluate quartz damage and repair options.
Does Quartz Need To Be Sealed?
Though quartz is non-porous, sealing is recommended to enhance stain protection. Sealing fills in microscopic crevices and creates an added moisture barrier. Annual sealing with a penetrating sealer formulated for quartz makes the surface more impervious to stains. It also replenishes the luster and polish worn away by cleaning and use over time.
How to Clean Quartz Countertops
- For routine cleaning, wipe down with a soft cloth and mild soap and water. Rinse thoroughly and dry with a clean cloth.
