Can Quartz Countertops Be Used Outside?

Quartz countertops have become an increasingly popular choice for both indoor and outdoor kitchens and entertainment spaces. With their durability, low maintenance, and customizability, quartz offers many advantages for exterior applications. Here is a detailed look at using quartz countertops outside.

What is Quartz?

Quartz is an engineered stone made from ground natural quartz crystals combined with resins and pigments. The resulting material is non-porous, stain-resistant, and incredibly hard and durable.

Unlike natural stone, quartz does not need to be sealed and is highly resistant to cracks, scratches, and heat. The resins allow quartz to be molded into a wide variety of colors, patterns, and textures. This versatility and durability make quartz an excellent choice for outdoor countertops and surfaces.

Benefits of Using Quartz Outdoors

There are several key benefits that make quartz well-suited for outdoor use:


Quartz has a Mohs hardness rating of 7, making it more scratch and chip resistant than most natural stones. This durability allows it to withstand heavy use and exposure to the elements outdoors.

Low Maintenance

Quartz requires very little maintenance compared to other surfaces. It does not need to be sealed, is stain resistant, and can be easily cleaned with soap and water. This makes care and upkeep simple for outdoor quartz.

Resists Weathering

Quartz is non-porous so it does not absorb moisture. This prevents the expansion and cracking that can happen to natural stone when exposed to repeated freeze-thaw cycles. Quartz can withstand sun, rain, snow, and temperature fluctuations.

Stain and Heat Resistance

Quartz resists stains from spills like wine, coffee, and oil that can ruin other surfaces. It also holds up to heat well and won’t scorch or burn like some materials.

Custom Options

Quartz comes in a wide selection of colors, patterns, finishes that allow you to customize your outdoor space. Popular options like concrete, marble, and granite looks are available.

Mold and Mildew Resistance

The non-porous nature of quartz prevents mold and mildew from growing in small crevices like they would on softer natural stones. This is essential for outdoor areas prone to moisture.

Best Practices for Using Quartz Outdoors

While quartz is highly durable for exterior use, following best practices will maximize its longevity and keep your countertops looking pristine:

Overhangs and Awnings

Providing shade with overhead covers can protect quartz from harsh UV rays that cause fading and discoloration over time.

Proper Installation

Outdoor quartz should be installed above ground level with proper support and seam adhesion to prevent cracking. Allow room for expansion and contraction between slabs.

Yearly Inspection

Inspect for any damage or deterioration around seams and edges. Re-applying caulk and sealant if needed prevents moisture issues.

Clean Routinely

Rinsing surfaces clear of dirt, grime, and debris prevents buildup that can become harder to remove over time.

Avoid Standing Water

Ensure countertops and surfaces slope properly to drain water. Avoid letting water pool which can lead to etching over time.

Use Trivets and Hot Pads

While quartz can take brief heat exposure, prolonged direct contact with extremely hot cookware could cause damage.

Check Manufacturer Warranty

Some quartz brands offer outdoor-specific warranties. Review coverage details and follow usage guidelines.

The heat resistance of quartz allows it to border fire pits without burning or cracking. Browse flame-like designs to complement the fire.


For cabinet doors, drawers, and faces, quartz provides a sleek facelift that withstands sun, rain, and humidity on outdoor cabinetry.


Does quartz need to be sealed outdoors?

No, quartz does not require sealing when used outdoors. Its non-porous nature prevents moisture absorption unlike natural stone.

What are the best quartz colors for outdoors?

Light and white quartz colors are best for reflecting sunlight and minimizing heating. Neutral tones like grays, tans, and concrete colors also work well.

Is quartz cheaper than granite for outdoors?

In most cases, quartz is less expensive than granite, making it a more budget-friendly outdoor surface option compared to natural stone.

Can you cut on quartz countertops outside?

Yes, quartz holds up well to being cut on, just be sure to use a cutting board to prevent damaging the surface over time.

How thick should outdoor quartz counters be?

A 3cm thickness is recommended for sufficient strength and durability on outdoor quartz countertops and surfaces.

Does cold weather affect outdoor quartz?

Quartz is resistant to thermal shock, severe temperature changes, and freeze-thaw cycles making it ideal for use in cold climates outdoors.


Quartz countertops offer many advantages that make them well suited for outdoor kitchens, bars, tables, and more. Their durability, weather-resistance, low maintenance, and design flexibility allow them to be customized for all types of exterior living spaces and entertainment areas. Following best practices for installation and care will help ensure outdoor quartz surfaces stand the test of time. With proper use, quartz countertops can provide long-lasting function and beauty to upgrade any outdoor oasis.
