Quartz countertops have become an increasingly popular choice for kitchen and bathroom surfaces in recent years. Made from ground quartz crystals combined with resins and pigments, quartz counters are valued for their durability, low maintenance, and variety of colors and patterns. However, many homeowners wonder: does quartz countertops chip?
What is Quartz?
Before diving into whether quartz counters can chip, it’s helpful to understand exactly what quartz is. Quartz is a mineral found abundantly in nature. It is comprised of silicon and oxygen atoms bonded together in a crystalline structure. Quartz is found in many different colors, but is commonly white or clear.
Quartz used in countertops is ground up into a fine powder. The quartz crystals are combined with pigments for color and resins for binding. This engineered quartz material is molded into slabs and polished to create the finished product installed in homes.
Why Quartz Countertops are Popular
There are many reasons quartz has become such a popular countertop choice:
- Durability – Quartz is very hard and scratch-resistant. It holds up well to heavy use in kitchens and bathrooms. The resin binders make quartz non-porous and impervious to stains.
- Low Maintenance – Unlike natural stone, quartz does not need regular sealing. Simple cleaning with soap and water is all that is required. The non-porous surface resists staining.
- Appearance – With a wide array of colors and patterns, quartz offers the look of natural stone without the maintenance. The look is modern and stylish.
- Non-porous – Liquids and stains do not penetrate the surface, making cleaning and sanitation easy.
- Heat Resistance – Quartz can withstand heat better than many other counter materials, protecting from damage by hot pans.
With this winning combination of form and function, it’s no wonder quartz has become a go-to choice for upscale kitchen and bath remodels. Homeowners are drawn to the low-maintenance convenience and sleek appearance.
Does Quartz Chip Easily?
Now we come to the key question: is quartz prone to chipping? The short answer is: quartz is resistant to damage, but chips are possible under the right circumstances.
Overall, quartz is quite durable thanks to its high hardness rating on the Mohs scale. On a scale of 1 to 10, with 10 being the highest, quartz rates a 7. This hardness makes it resistant to scratches, chips, and cracks.
However, quartz is not completely invincible against damage. Cracks and chips are possible, especially on the corners and edges of the countertop. Here are some of the ways chips can occur:
A significant impact from a heavy object can potentially crack or chip a quartz counter. Pots, pans, or appliances dropped with force onto the surface may cause damage. Quartz is hardy, but a major impact overwhelms the structural integrity.
Most quartz installers will encourage an overhang of only 1-2 inches. Anything more than that risks creating a weak point subject to chipping, particularly on the corners. The weight of excess overhanging quartz leads to stress fractures and chips.
If the countertop is not installed properly, it may crack under pressure. Uneven support or improper seam joining during installation can create structural weaknesses. This leads to an increased chance of damage during use.
While quartz has good heat resistance, extreme temperatures can still pose problems. Putting very hot pans directly on the surface, especially if already compromised by a nick or scratch, may cause chips or cracks.
Cuts and Scratches
Cuts and scratches create vulnerabilities in the surface where more extensive chips can occur later. Deep cuts should be avoided or filled in properly by a professional.
How to Prevent Quartz Chips
Quartz is not immune to damage, but there are ways to prevent chips and maximize the durability of your investment:
Select a High-Quality Quartz
Higher quality quartz made from pure crystalline powder is more resilient than products with more binders and filler. Research brands and read reviews to select a top-tier manufacturer.
Opt for Thicker Quartz
Thicker quartz slabs – 3 cm rather than 2 cm – provide enhanced durability and structure. The extra thickness allows for more resistance against impacts.
Make sure your countertop is installed by an experienced professional. Proper seam work and adequate structural support prevents cracks and weaknesses.
Keep counter overhangs under 2 inches to minimize stress points. Use an angled support along longer spans to improve structural integrity.
Handle With Care
Be gentle setting down pots, pans and heavy items. Don’t let them drop on the quartz. Regularly check for any nicks or scratches needing repair.
Use Trivets and Cutting Boards
Use heat resistant trivets for hot pots and pans. Cutting directly on the counter should be avoided. Use a cutting board to protect the surface.
Clean Spills Promptly
Clean up food, liquids or chemicals quickly to avoid deep staining. Though resistant to staining, quartz can absorb some dyes over time if not cleaned.
By selecting high-quality quartz, handling gently, keeping overhangs short, and cleaning regularly, homeowners can enjoy their counters for years without significant chips or damage.
What to Do if Your Quartz Chips or Cracks
Despite your best efforts, chips or cracks may still happen. If you notice any nicks, scratches or damage, take action right away:
- For small chips or nicks, use a stone polishing kit for quartz to smooth the area. Buff gently to restore the finish.
- Consult a professional stone restoration company for more significant chips. They have products to repair cracks and restore structure.
- For deep cracks or major damage, replacement of that section of stone may be required. A pro can cut out and install a new piece.
- If damage encompasses more than 30% of the surface area, a full countertop replacement may be needed.
- Address any underlying causes, like inadequate support or large overhangs, before installing new counters.
Never attempt do-it-yourself repairs on major chips or cracks. The structural integrity is compromised and professional equipment and products are required.
FAQs About Quartz Countertops and Chipping
Many homeowners have questions about quartz chipping. Here are answers to some common frequently asked questions:

Does Quartz Absorb Stains?
Quartz is renowned for its stain resistance. However, some people wonder if liquids can penetrate the surface and cause stubborn staining. Understanding quartz’s properties provides the answer.
The Composition of Quartz
To understand quartz’s stain resistance, it’s important to first look at what it’s made of. Natural quartz crystals are combined with pigments and resin binders to create an engineered slab.
Unlike porous natural stones, the resins make quartz non-porous. This means fluids have a hard time penetrating beyond the surface. The resin binds the quartz particles into a tight formation that liquids cannot easily soak into.
What Kinds of Stains?
When evaluating quartz stain resistance, it’s helpful to consider different categories of stains:
These include stains from food residues, oils, dyes from liquids like wine or coffee, and other common kitchen substances. The non-porous quartz resists absorption of these surface stains. With prompt cleaning, most can be removed without any penetration or residue left behind.
Prolonged acid exposure can potentially “etch” the surface of quartz and create light marks. Citrus juices, vinegar, or cleaning products with low pH levels can have this effect over time. However, etched areas are only surface marks that do not permeate the full depth of the quartz.
The biggest concern is deep, penetrating stains that discolor the entire thickness of the quartz. However, due to the low porosity, most household stains stay on the surface and do not cause this level of damage.
Stain Testing by Quartz Brands
Leading quartz manufacturers rigorously test their products for stain resistance:
- Caesarstone claims their quartz resists lemon juice, vinegar, wine, tea, soda, olive oil and other common household substances.
- Cambria states their quartz is unaffected by ketchup, mustard, wine, lemon, tea, soda, vinegar and olive oil.
- Silestone also attests their quartz counters are highly stain resistant and tests for foods, oils, and organic compounds.
This extensive testing by reputable brands confirms the resilience of quality quartz against various staining agents.
How to Prevent Staining
To maximize stain resistance, these tips will keep your quartz pristine:
- Clean up spills quickly, don’t let them sit
- Use sealers/surfaces sprays for added protection
- Avoid prolonged exposure to very acidic substances
- Use trivets for hot pots and pans
- Cut on boards, not directly on the quartz
- Follow manufacturer instructions for cleaning products
With proper care, quartz counters will stay looking like new for many years of use.
Removing Stains from Quartz
For best results removing stains:
- First try mild soap and warm water
- For stubborn marks, use a non-abrasive cleaner designed for stone surfaces
- Gently scrub with a soft cloth, sponge or nylon brush
- Avoid abrasive pads and powders which may scratch the finish
- For etched marks from acids, use an alkalinity enhancer
Do not use harsh chemicals like bleach, alkaline additives like baking soda and vinegar, or alkaline bases like ammonia. Always refer to your quartz manufacturer’s care guide.
The non-porous resins in quality quartz make it highly resistant to significant staining. Surface marks occur but do not permeate if cleaned promptly. With proper care and cleaning, quartz countertops will stay looking like new for many years without absorbing stubborn stains.
How Heat Resistant is Quartz?
Quartz countertops are commonly used around stoves, ovens, and other heat-generating appliances. But how much heat can quartz withstand? Understanding the thermal properties of these popular counters is important.
The Thermal Properties of Quartz
Quartz is an engineered product made from crushed quartz crystals combined with resins and pigments. The key thermal traits of quartz are:
- Low thermal conductivity – Quartz does not easily transmit heat. Heat travels slowly through quartz, rather than quickly like metal. This helps buffer the surface from heat damage.
- Resistance to thermal shock – Rapid temperature changes which can fracture natural stone are better weathered by quartz.
- Resistance to expansion – When heated, quartz does not expand as dramatically as natural stone, avoiding cracks.
Thanks to these properties, quartz has relatively good heat tolerance compared to other countertop materials.
Heat Tolerance Temperature
Most major quartz manufacturers rate their products for heat exposure up to about 150°C or 300°F. Prolonged direct contact above these temperatures risks potential damage.
However, brief contact with hot pans straight from the oven or burner would normally not exceed this limit. The quartz surface can withstand quick exposure to very hot cookware.
Repeated, extended exposure to extreme heat may compromise the resins over time. But normal cooking use is well within quartz’s heat tolerance threshold.
Preventing Heat Damage
To prevent any heat-related damage:
- Always use heat trivets for hot pots and pans
- Don’t put baking sheets or casserole dishes directly from the oven onto quartz
- Use care with electric griddles, crock pots, or other appliances
- Don’t expose the surface to open flames
With basic precautions, quartz stands up well to typical kitchen heat.
Signs of Heat Damage
Look for these signs of excessive heat exposure:
- Small brown or yellow dots
- Cracks radiating from a point of impact
- Pitting, bubbling or a melted appearance
If you notice these warning signs, discontinue exposure to extreme heat in that area and have a professional inspect for repairs needed.
What to Do if Heat Damage Occurs
For light heat damage, gentle buffing with fine grit wet sandpaper may reduce signs of scorching.
If damage is more extensive, replacement of the damaged section may be required. A professional can cut out the affected area and install a new quartz piece.
For widespread heat damage exceeding 30% of the surface, a full quartz countertop replacement may be necessary.
Be sure to correct any underlying issues, like inadequate trivet use or poor heat resistance of a particular quartz type.
Improving Heat Resistance
To boost heat protection, choose an engineered quartz made for high heat, such as:
- Silestone Helix+ – Designed to withstand brief exposure up to 535°F.
- Cambria Torquay – Can tolerate sustained temperatures up to 425°F.
- Caesarstone Outdoor – Handles brief exposure to 752°F.
Higher priced quartz aimed at uses around outdoor kitchens and baking areas offer improved thermal traits.
Standard quartz counters can tolerate intermittent exposure to moderate heat. With proper precautions against sustained high temperatures, quartz stands up well to routine kitchen use. Paying a bit more for high-performance formulations designed for greater heat resilience provides an extra degree of protection.
How to Clean Quartz Countertops
To maintain the good looks of quartz counters, regular cleaning is essential. Here are some best practices for cleaning quartz:
For daily cleaning, simple soap and water usually suffice:
- Use a mild soap and warm water
- Avoid abrasive cleaners or pads that could scratch
- Use a soft cloth or sponge in a circular motion
- Rinse thoroughly and dry with a soft towel
Cleaning spills right away prevents staining. Quartz resists staining but drying liquids increase absorption risk.
For stubborn stains:
- First scrub with warm water and mild non-abrasive soap
- If needed, use a non-bleach stone cleaner
- Apply the cleaner to a soft cloth and rub gently on the stain
- Rinse thoroughly afterwards and dry with a soft towel
Avoid harsh chemicals like oven cleaners, alkaline additives, bleach, ammonia, or acidic cleaners. Only use a specialized stone cleaner.
Prolonged exposure to acidic substances like citrus, wine or vinegar can “etch” the surface leaving light marks. To remove:
- First clean with soapy water to remove residue
- Apply an etching remover or marble polishing compound
- Buff gently with a soft cloth to blend the area
To safely disinfect quartz:
- Mix a ratio of 1/3 cup of bleach to 1 gallon of water
- Wipe down surfaces with a soft cloth soaked in the solution
- Let the solution sit 3-5 minutes then rinse clear
- Avoid highly concentrated bleach
Using a conditioning stone polish routinely keeps quartz looking its best.
- Apply a small amount of polish to a soft cloth
- Use circular motions to spread across the surface
- Buff until any haze disappears for a shine
- Reapply polish weekly for best results
Be sure to select a polish specifically designed for engineered quartz. Stone polishes maintain the luster and provide added protection.
Caring for quartz properly keeps it looking as good as new. With proper products and techniques, quartz countertops will retain their beautiful, flawless appearance for years. Follow manufacturer guidelines and avoid abrasive cleaners
