Quartz stone countertops have become an increasingly popular option for kitchen and bathroom remodeling projects in recent years. But what exactly is quartz stone, and what makes it a good choice for countertops? Here is a detailed overview of what quartz stone countertops are, their benefits, how they compare to other countertop materials, costs, maintenance, and more.
What is Quartz Stone?
Quartz stone is an engineered stone made from crushed quartz, resin, and pigments that are combined and formed into slabs. It is sometimes referred to as engineered stone or reconstituted stone. The quartz content typically makes up 90-94% of the material, while polymer resins account for 6-10%.
The crushed quartz used in manufacturing provides strength, hardness, and scratch resistance, while the polymer resin binds the material together into a durable, non-porous surface. Pigments are added to produce the various colors and patterns available.
Compared to natural stone like granite and marble, quartz offers more consistency in color and pattern. The manufacturing process allows quartz to be engineered without the natural variations and imperfections found in natural stone.
Benefits of Quartz Stone Countertops
There are several reasons why quartz has become a top choice for countertops:
- Durability – Quartz is extremely hard and resistant to scratches, chips, cracks, and heat. It can withstand heavy daily use.
- Low Maintenance – Quartz requires very little maintenance compared to other surfaces. Simple cleaning with soap and water is enough for routine care.
- Stain Resistance – Quartz is non-porous, so it resists staining from spills, oils, juices, and other liquids.
- Consistent Appearance – The engineered manufacturing process creates a very consistent look. There are no natural pits, cracks, fissures, or imperfections.
- Variety of Colors/Patterns – From solid whites to bold colors and realistic patterns, there are many options to fit any style.
- Hygienic – With no pores, quartz does not harbor bacteria or microorganisms and is ideal for kitchens and baths.
- Integrated Sink Options – Special quartz slabs allow sinks to be seamlessly integrated into the countertop surface.
- Heat Resistance – Quartz can withstand heat better than many materials like solid surface or laminate. However, it is still susceptible to damage from extreme direct heat.
How Does Quartz Compare to Other Countertops?
Quartz is often compared to other popular countertop materials like granite, marble, laminate, and solid surface. Here is how it stacks up:
Quartz vs. Granite
Granite is a natural stone that offers a unique, high-end look. However, it requires more maintenance and sealing to prevent staining. Granite is also more prone to chipping, cracking, and variations in color/pattern. Overall, quartz provides better consistency and ease of care compared to granite.
Quartz vs. Marble
Marble is another premium natural stone counter option. It offers a luxurious, timeless look but is much more delicate and prone to etching, scratches, and stains. Marble requires resealing every 6-12 months. In contrast, quartz is extremely durable and keeps its appearance with minimal maintenance.
Quartz vs. Laminate
Laminate countertops are affordable and come in endless options. However, they can be easily scratched or damaged by heat, moisture, and impact. The resin coating can wear down over time leading to delamination. Quartz is better for durability and long-lasting beauty.
Quartz vs. Solid Surface
Solid surface (like Corian) provides a seamless, built-in look for countertops and sinks. But it still suffers surface damage from heat, scratches, and stains over time. It also lacks the natural beauty of quartz’s stone-like patterns.
Cost of Quartz Countertops
Quartz countertops range from $50-100 per square foot installed. Total costs for a typical 30 square foot counter area generally range from $1,500-3,000. Several factors affect overall quartz countertop costs:
- Brand – Well-known brands like Silestone, Cambria, Caesarstone, and Viatera are on the higher end. Lesser known, cheaper brands can help reduce costs but may sacrifice quality.
- Color/Pattern – Simple solid colors are most affordable. Multi-colored stone-like patterns and designs can increase the price per square foot.
- Thickness – Standard thickness is 3/4″. Going up to 1 1/4″-2″ thick slabs adds cost but provides more durability and depth.
- Edge Styles – Decorative edges like bullnose, ogee, and chamfered add complexity and cost. A standard eased or straight edge is most economical.
- Fabrication – Precisely cutting and installing the countertops adds the most to overall project costs. Hiring experienced professionals is advisable over DIY.
- Additional Products – Integrated sinks, backsplashes, special features increase costs but can enhance the beauty and functionality.
Maintenance and Care for Quartz Countertops
- Here are some tips for properly caring for quartz countertops:
Cleaning
- For regular cleaning, use a gentle soap/detergent and warm water applied with a soft cloth or non-abrasive sponge.
- Rinse thoroughly to remove any soap residue.
- For stubborn stains, use a non-abrasive cleaner designed for stone surfaces.
- Avoid abrasive cleaners, pads, or brushes that could lead to a dull finish.
Prevention
- Always use cutting boards for food preparation to prevent scratching from knives.
- Avoid exposing the surface to strong chemicals like paint removers, oven cleaners etc.
- Use trivets or hot pads under pots, pans, and other heat generating kitchenware.
- Clean up any spills immediately to prevent possible staining.
- Check manufacturers care guidelines for proper maintenance products and procedures.
Sealing
- Quartz does not require regular sealing like natural stone. Most manufacturers do not recommend using sealants on quartz.
Repairs
- Minor damage like light scratches can often be buffed out through refinishing. Consult a countertop specialist for repairs.
- For chips, cracks, or major damage, a full replacement of the damaged section may be needed. Save excess remnants from the original install whenever possible.
FAQs
Is quartz better than granite?
Quartz is generally considered lower maintenance than granite. It does not require regular sealing, is less prone to staining/etching, and keeps its consistent appearance longer than granite. However, granite remains popular for its natural beauty and prestige.
Is quartz better than Corian or solid surface?
Quartz is more durable and heat/stain resistant compared to solid surface materials like Corian. It also offers an attractive, natural stone look versus the uniform man-made appearance of solid surfaces.
Does quartz have radon or other health risks?
Quartz surfaces meet all safety requirements and are considered non-toxic and safe for home use. They contain no radon or other health risks. Any concerns about off-gassing or radiation are unfounded according to research.
Is quartz porous?
Unlike natural stone, quartz is non-porous due to its resin content, so it does not require sealing or harbor bacteria growth. Liquid spills can easily be wiped away instead of soaking into the surface.
Can you repair quartz countertops?
Minor damage like scratches may be minimized through buffing and re-polishing. But chips, cracks, stains, or major damage usually require full replacement of the quartz slab. Excess material from the original installation should be saved.
Does quartz stain?
Quartz is highly resistant to staining but not completely stain-proof. Prolonged exposure to certain materials like oil, dyes, or wine can potentially cause staining. Immediate cleanup of spills helps maintain its stain resistance.
Is quartz toxic?
Quartz contains no toxic materials and is certified safe for use in countertops according to government health agencies. Some older reports warning about potential toxicity are outdated and inaccurate.
Is quartz environmentally friendly?
As an engineered product made from crushed quartz and resins, some consider quartz less eco-friendly than natural stone. But advancements in manufacturing and recycling make quartz a greener option than in the past.
Does quartz need to be sealed?
Unlike granite and marble, quartz does not require regular sealing. The polymer resins make quartz non-porous, so sealing is generally not needed to prevent staining. However, some still recommend occasional sealing for added protection.
Conclusion
With its durability, low-maintenance, and stylish appearance, quartz has clearly become a top choice for kitchen and bathroom countertops. While not inexpensive, its long lifespan and resistance to scratches, stains, and cracks make it a wise investment for many homeowners. Proper care includes avoiding abrasive cleaners, minimizing heat exposure, and cleaning up spills rapidly. For those seeking an attractive, practical, and easy-care countertop, quartz is sure to provide lasting beauty and satisfaction.
