Quartz countertops have become an increasingly popular option for kitchen and bathroom remodeling projects in recent years. Often marketed as an innovative, low-maintenance, and stylish alternative to natural stone and other materials, quartz offers many attractive benefits for homeowners. However, one of the most common questions that arises is: how durable is quartz as a countertop material? In this comprehensive guide, we will examine the durability and performance factors that make quartz an excellent choice for busy kitchens and baths.
What is Quartz?
Before analyzing the durability of quartz, it helps to understand exactly what this material is. Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins, pigments, and other compounds. The quartz content typically makes up 90% or more of the material.
This blend creates an incredibly hard, non-porous surface that is resistant to scratches, stains, heat, and water. The manufacturing process allows quartz to be molded into countertops of all shapes, sizes, colors and finishes. The customization and consistency of quartz are two of its winning qualities compared to natural stone.
Hardness and Scratch Resistance
When reviewing durability, hardness and scratch resistance are two key indicators. On the Mohs scale of mineral hardness, quartz crystals themselves rate 7 out of 10. This is extremely hard, especially compared to other natural stones used for countertops:
- Marble: 3-4
- Soapstone: 1-2
- Granite: 6-7
- Concrete: 3-4
In its engineered form, the hardness of quartz ranges from 8-9 on the scale due to the addition of polymers in the manufacturing process. This makes it more scratch resistant than granite. Quartz holds up beautifully to everyday use, eliminating the need for special cutting boards. It can withstand plenty of dropped pots, pans, and utensils without damage. Over time, quartz may develop minor surface scratches but its color and polish integrity remain unaffected. It does not require ongoing sealing or polishing to maintain its durability.
Stain Resistance
In addition to superior hardness, quartz resists staining which enhances its use as a kitchen countertop material. The non-porous nature of quartz prevents liquids and oils from penetrating the surface, making quartz extremely stain proof. Quartz easily wipes clean with no need for sealing.
Even after prolonged exposure, stains can be removed using a solvent-free cleaner or baking soda paste. More stubborn stains may require a little elbow grease and non-abrasive scouring pad. When cared for properly, quartz maintains its stain resistance for many years. Some sources cite stain resistance as one of the biggest advantages of quartz over natural stone countertops.
Heat Tolerance
Quartz holds up beautifully to normal kitchen heat. Hot pots and pans can be placed directly on quartz surfaces without worry. Moderate heat exposure will not damage, discolor or mark the material.
However, like any stone surface, quartz can be vulnerable to sudden and rapid temperature changes or extreme heat. Prolonged direct contact with very hot cookware could potentially cause minor discoloration. Exposing the surface to open flames is not recommended.
In general practice though, quartz has excellent heat tolerance for typical cooking needs. Using trivets or hot pads is always advised to protect investments in beautiful countertops of any kind. With routine care, quartz withstands everyday use around stovetops and ovens without issue.
Impact Resistance
The dense, non-porous nature of quartz makes it very resilient to impacts. Quartz’s durability and strength minimize the concern for chips, cracks, and breaks from normal wear and tear. Minor nicks or marks, if they do occur, cannot penetrate the surface so the overall integrity remains undamaged.
Compared to other stones, especially marble, the high-performance composition of quartz makes it very impact resistant. However, like any rigid material, quartz can be vulnerable to cracks and structural damage from excessive force or trauma such as standing on or hitting the edge. Proper use and care is always advised to enhance the long-lasting beauty of quartz surfaces.
Non-Porous
Quartz density provides water and liquid repellency, an asset for kitchens and baths. Since it is non-porous, spills and messes cannot penetrate the surface. Liquids simply bead up and wipe away, inhibiting staining and damage.
Quartz’s non-absorbent properties also eliminate the need for periodic sealing required by natural stones. This saves maintenance time and hassle. The material maintains its water-resistance and does not require resealing over time. Non-porosity makes quartz an ideal choice for hygienic food prep areas.
Mold/Mildew Resistant
The non-porous nature of quartz also prevents the growth of mold, mildew and bacteria. Without pores for moisture and microbes to penetrate and build up, quartz inhibits their spread. The manufacturer warranties of many quartz brands cite antimicrobial and anti-microbial properties as well.
This is a useful feature for bathrooms, kitchens, and other rooms prone to humidity and dampness. Natural stone surfaces may require occasional resealing and special cleaners to control mold growth. With quartz, just routine wipedowns provide effective resistance. This helps kitchen and bathroom countertops stay fresh and appealing for many years.
Durability Comparison to Other Countertop Materials
How does the durability of quartz compare specifically to popular countertop materials like granite, marble, laminate, and concrete? Here is a brief durability overview:
- Granite: Very durable but slightly more prone to staining/etching than quartz. Requires periodic sealing.
- Marble: Softer and more porous than quartz. Stains easily without proper sealing and maintenance. ETching and chips are concerns.
- Laminate: Very affordable option but not as scratch, heat or stain resistant as quartz. Durability depends on thickness and quality.
- Concrete: Durable but requires intensive sealing to resist stains and etching. Can crack if not properly cured and sealed.
- Quartz: Extremely hard and scratch resistant. Resists stains, heat, moisture and impact very well. Non-porous and mold/mildew resistant.
Clearly, quartz as a class of material is exceptionally durable compared to other typical countertop options. However, it is not completely indestructible. The next section covers a few factors that can potentially impact its longevity.
Factors that Can Affect Quartz Durability
While quartz itself is a very durable material, certain factors can impact its performance and longevity:
Quality of Installation
Like most home projects, proper installation is key to durability. Seams and edges need smooth finishes. Supporting structures must be stable. Any imperfections in installation can lead to cracks or weaknesses down the road. Be sure to use experienced professionals for templating and fitting quartz pieces.
Sun Exposure
Direct, prolonged sun exposure can potentially cause some discoloration in quartz surfaces over time. This is especially true for lighter colors. Make sure to account for sunlight areas in your kitchen or bath layouts. Adding window treatments can help prevent extensive UV light exposure.
Chemical Exposure
Although quartz stands up to many cleaners and chemicals, prolonged exposure to strong alkaline or acidic products (like oven cleaners) could potentially etch the surface. Follow manufacturer guidelines for approved cleaning agents and avoid corrosive compounds.
Heavy Impacts
Chips, cracks and breakage are possible with excessive impacts, especially at vulnerable corners and edges. Avoid climbing, sitting or standing on quartz countertops to prevent damage. Handle heavy dishes and objects with care.
Thermal Shock
Rapid temperature swings can stress any natural stone material. Allow hot cookware to cool before placing on quartz surfaces. Use trivets and hot pads to minimize direct heat exposure. Avoid pouring extremely hot/cold liquids directly on quartz.
Abrasions
While quartz stands up beautifully to normal use, consistent heavy abrasion over the same spot can wear the surface over time. Use cutting boards for food prep tasks to prevent localized abrasions. Do not grind spices or other materials directly on the countertop.
By being mindful of these factors, quartz countertops will maintain their good looks and durability for many years. Follow manufacturer care guidelines and use common sense to prevent unnecessary damage. With routine maintenance, quartz offers long-lasting performance and beauty.
