Quartz Countertops Guide: Everything Homeowners and Fabricators Need to Know
This quartz countertops guide covers everything fabricators and homeowners need to know.
Quartz countertops are engineered surfaces made from roughly 90-94% ground natural quartz crystals bound together with 6-10% polymer resins and pigments. Unlike natural stone, quartz is manufactured in controlled factory conditions, producing consistent colors and patterns without the natural variations found in granite or marble. Quartz accounts for over 30% of all countertop installations in the US and is the most popular surface material for kitchen renovations.
TL;DR
- Quartz countertops cost $50-$150 per square foot installed, depending on brand and color
- Made from 90-94% natural quartz crystals plus resins and pigments
- Non-porous: never needs sealing, resists stains, and won't harbor bacteria
- Not heat-resistant: hot pans can damage the resin binders (use trivets)
- Major brands: Cambria, Silestone, Caesarstone, MSI, LG Viatera, Hanstone
- Available in hundreds of colors, including realistic marble and concrete looks
- Average kitchen (40 sq ft) costs $3,000-$6,000 installed
- Fabrication requires dust control (silicosis risk from cutting)
What Is Quartz and How Is It Made?
Quartz countertops are often confused with quartzite, which is a natural stone. They're completely different products.
The Manufacturing Process
- Raw material preparation: Natural quartz crystals are mined, then ground into fine granules of varying sizes
- Mixing: The ground quartz is combined with polymer resins (typically polyester), pigments for color, and sometimes recycled glass or mirror chips for visual effect
- Compaction: The mixture is poured into molds shaped like slabs, then compressed under vacuum pressure (using a process called Breton technology) at approximately 100 tons of force
- Curing: The compressed slabs are heated in kilns at 180-200 degrees Fahrenheit to cure the resins
- Finishing: Slabs are polished, honed, or textured to the desired surface finish
- Quality control: Each slab is inspected for color consistency, surface defects, and dimensional accuracy
A standard quartz slab measures approximately 120" x 55" (about 46 sq ft) or 130" x 65" (about 58 sq ft) in jumbo format.

Performance Characteristics
Durability
Quartz rates 7 on the Mohs hardness scale, making it harder than granite (6-6.5) and significantly harder than marble (3-5). It resists scratching from normal kitchen use, though cutting directly on the surface will eventually dull both the countertop and your knives.
Heat Resistance
This is quartz's main weakness. The resin binders begin to discolor or crack at temperatures above 300 degrees Fahrenheit. A hot pan directly from the stove or oven can leave a permanent scorch mark. Always use trivets or hot pads.
| Heat Source | Temperature | Safe on Quartz? |
|---|---|---|
| Coffee mug | 160-180 degrees F | Yes |
| Warm pan | Under 250 degrees F | Yes |
| Hot pan from stove | 300-500 degrees F | No, use trivet |
| Oven dish | 350-450 degrees F | No, use trivet |
| Crock pot | 200-300 degrees F | Use caution |
Stain Resistance
Because quartz is non-porous, it resists staining far better than natural stone. Spills from wine, coffee, oil, and acidic foods wipe away without soaking in. However, some strongly pigmented substances (turmeric, permanent marker) can stain if left for extended periods.
Maintenance Requirements
- Daily: Wipe with mild soap and water
- Weekly: Clean with a non-abrasive quartz cleaner
- Never needed: Sealing (unlike granite or marble)
- Avoid: Bleach, abrasive cleaners, scouring pads, oven cleaner
UV Sensitivity
Quartz can fade or yellow with prolonged direct sunlight exposure. This makes it a poor choice for outdoor kitchens or countertops directly adjacent to large south-facing windows. If you have significant sun exposure, ask about UV-resistant formulations or consider natural stone instead.

Fabrication Considerations for Shops
Cutting Quartz
Quartz fabrication requires:
- CNC bridge saw or router with diamond-tipped blades
- Continuous water flow during cutting (wet cutting is mandatory)
- Dust collection systems rated for respirable crystalline silica
- OSHA-compliant air monitoring (PEL: 50 micrograms/m3 for respirable crystalline silica)
Quartz generates significant silica dust during cutting. OSHA's silica standard (29 CFR 1926.1153) requires engineering controls, respiratory protection programs, and medical surveillance for exposed workers.
Edge Profiling
Quartz machines well and holds crisp edge profiles. The resin content makes it slightly less prone to chipping during edge work compared to natural granite, but the material generates more heat during routing. Adequate water cooling prevents resin discoloration along the edge.
Seam Considerations
Quartz seams are bonded with color-matched epoxy adhesive. Because quartz surfaces are consistent in color and pattern, seams tend to be less visible than in natural stone, where matching veining across a seam requires careful planning.
Best practices for quartz seams:
- Place seams at natural break points (behind sinks, at inside corners)
- CNC-cut mating edges for flatness
- Use manufacturer-supplied adhesive kits for color matching
- Keep seams under 1/16" wide after joining
Slab Nesting and Yield
A standard quartz slab yields 60-80% usable material for a typical kitchen job. AI nesting software analyzes all pieces needed across multiple jobs and optimizes cutting layouts, often fitting pieces from different jobs on the same slab to reduce waste from the industry average of 25-30% down to 10-20%.
Choosing the Right Quartz for Your Project
For Kitchens
Focus on: stain resistance (quartz excels), heat resistance (use trivets), and pattern durability. Choose 3cm thickness for most applications. Popular kitchen choices include marble-look whites and warm-toned neutrals.
For Bathrooms
Focus on: water resistance (quartz is excellent), ease of cleaning, and aesthetic flexibility. 2cm thickness works well for vanities with plywood substrate. Consider matte or honed finishes for a contemporary look.
For Commercial Spaces
Focus on: durability, consistency across large installations, and low maintenance. Silestone's bacteriostatic properties make it popular for healthcare and food service. Solid colors hide wear better than veined patterns in high-traffic areas.
FAQ
Is quartz more expensive than granite?
Not necessarily. Budget quartz ($50-$70/sq ft) and budget granite ($45-$70/sq ft) are comparable. Premium quartz (Cambria, Caesarstone) runs $100-$150/sq ft, while premium exotic granites can reach $150-$200+/sq ft. Mid-range quartz is often slightly more expensive than mid-range granite.
Does quartz stain?
Quartz is non-porous and highly stain-resistant, but not stain-proof. Strongly pigmented substances like turmeric, red wine, or permanent marker can leave marks if not cleaned promptly. Most household spills wipe away easily.
Can I put hot pans on quartz?
No. Direct contact with pots and pans above 300 degrees Fahrenheit can damage the resin binders, causing discoloration or cracking. Always use trivets or hot pads. This is quartz's primary drawback compared to granite and quartzite.
How long do quartz countertops last?
With proper care, quartz countertops last 25-50+ years. The resin binders are the limiting factor; they can yellow or degrade over decades. Most manufacturers offer 15-year to lifetime warranties.
Is quartz good for outdoor kitchens?
No. UV exposure causes quartz to fade and yellow over time. The resin binders degrade faster in direct sunlight. Use granite, quartzite, or sintered stone for outdoor applications.
Do quartz countertops increase home value?
Yes. Quartz countertops are among the most desirable kitchen features for homebuyers. The National Association of Realtors estimates that a kitchen remodel with quartz countertops returns 60-80% of the investment at resale.
How do I clean quartz countertops?
Daily cleaning with warm water and mild dish soap is sufficient. For stubborn spots, use a non-abrasive quartz-specific cleaner. Avoid bleach, abrasive pads, and oven cleaners. For dried-on food, use a plastic scraper rather than a metal blade.
What edge profile is most popular for quartz?
Eased (slightly rounded) is the most popular edge profile, followed by beveled and half bullnose. These simple profiles work well with quartz's consistent pattern and suit both modern and traditional kitchens.
Is quartz countertop fabrication dangerous?
Cutting and grinding quartz generates respirable crystalline silica dust, which can cause silicosis with prolonged exposure. OSHA requires wet cutting, dust collection, respiratory protection, and medical monitoring for fabrication workers. Homeowners face no risk from installed quartz countertops.
Can quartz be repaired if chipped?
Small chips (under 1/4") can be filled with color-matched epoxy by a professional fabricator. Larger chips or cracks may require section replacement. Many manufacturers cover defects under warranty but not damage from impact or misuse.
What's the difference between quartz and quartzite?
Quartz is an engineered product (ground quartz + resin). Quartzite is a natural metamorphic rock quarried from the earth. They have different properties: quartz is non-porous but heat-sensitive; quartzite is heat-resistant but requires sealing. They also look different, with quartzite showing natural geological patterns.
Which quartz brand is best?
There's no single "best" brand. Cambria offers the widest color selection and is made in the US. Silestone leads in sustainability features. Caesarstone has the longest track record. MSI provides the best value. Choose based on your priorities: color selection, warranty, price, or sustainability.
