Can Granite or Quartz Be Used Outside?
As we embrace the warmer months and spend more time outdoors, many homeowners begin turning their attention to their gardens — not just as green spaces, but as true extensions of their homes. Outdoor kitchens, BBQ surrounds and alfresco dining areas are growing in popularity, offering a perfect blend of functionality and lifestyle.
When planning these outdoor spaces, the choice of surface materials becomes crucial. Natural stone is a strong contender, offering both beauty and resilience. But a common question we hear at Oxford Stone Craftsmanship is: “Can granite or quartz be used outside?”
The short answer: granite – yes, quartz – definitely not. Let’s explore why.
Granite: A Robust Choice for Outdoor Stone Projects
Granite is one of the most suitable natural stones for outdoor applications. Known for its strength, density and weather resistance, it’s a popular choice for everything from kitchen worktops to garden features — and it performs beautifully in outdoor settings.
Why granite works well outdoors:
- Highly durable – Granite is naturally hard and can withstand the elements, including heat, rain and frost.
- UV resistant – Unlike some engineered stones, granite won’t fade or discolour in the sun.
- Low maintenance – With regular sealing and simple cleaning, granite can last decades outdoors.
- Visually striking – Its natural veining and range of colours add elegance and character to outdoor kitchens and BBQ surrounds.
Ideal uses for granite outdoors:
- Outdoor kitchen worktops
- BBQ surrounds and counters
- Stone cladding for seating or fire pits
- Outdoor bar areas and preparation zones
Care tip: While granite is tough, it’s still a natural material with microscopic pores. We recommend sealing outdoor granite surfaces annually to help resist stains from grease, wine or food spills.
Quartz: A Big No-No for Outdoor Use
Quartz surfaces are incredibly popular indoors thanks to their sleek appearance and low maintenance, but when it comes to outdoor use, quartz simply doesn’t belong.
Why quartz shouldn’t be used outside:
- Not UV stable – Quartz surfaces contain resins that react poorly to sunlight, causing yellowing, fading or warping over time.
- Heat sensitive – Prolonged exposure to direct sunlight can cause expansion and even cracking.
- Weathering issues – Rain, frost and outdoor temperature fluctuations can damage the structural integrity of quartz over time.
Even if placed in a partially sheltered outdoor kitchen or covered patio, quartz is not built to handle the changing outdoor environment. Its beautiful finish simply can’t stand up to the UK’s unpredictable weather.
Important reminder: Manufacturers’ warranties for quartz surfaces generally do not cover outdoor use — using it externally could void any product guarantee.
Choosing the Right Stone for Your Alfresco Space
Selecting the right stone for your outdoor project depends on how and where it will be used. Here’s a breakdown of popular options and what to keep in mind for each:
Granite – A top choice for outdoor kitchens and surfaces. It’s extremely durable, naturally UV resistant, and holds up well in all weathers. Just be sure to seal it annually to keep it protected.
Quartz – Best kept indoors. It’s not suitable for outdoor use due to its sensitivity to UV light and heat. Over time, exposure to the elements will cause damage that can’t be reversed.
Slate – A great natural option for garden paving or wall cladding. Slate has a rustic appearance and is slip-resistant, making it ideal for high-traffic outdoor areas.
Sandstone – Often used for patios and garden paths. Sandstone has a textured surface and warm tones that suit outdoor aesthetics beautifully. It performs well outside when properly sealed.
Marble – Can be used outdoors but requires caution. It’s prone to weathering, particularly in exposed areas. Best suited to covered or sheltered alfresco zones, and should be sealed regularly to protect its surface.
If you’re unsure which stone is best for your needs, our team is always happy to advise based on your space, usage, and design goals.
Outdoor Stone Care Essentials
To keep your outdoor stone looking its best all year round:
- Clean regularly using warm water or a mild, pH-neutral cleaner. Avoid acidic or harsh chemicals.
- Seal annually to protect against moisture, stains and UV damage (especially for granite and sandstone).
- Use covers for BBQ areas and outdoor kitchens during winter or wet periods.
- Address spills promptly, particularly from food, oils or acidic substances like lemon juice or vinegar.
