Granite is a durable and hardwearing natural stone that is often used for countertops, flooring, and other surfaces. While granite is resistant to many elements, it is generally not prone to fading in sunlight. However, prolonged exposure to sunlight and certain conditions can lead to other types of damage or changes in appearance, which many would call it as “Granite Fade” or “Dull Granite”. 


Understanding Granite Sun Fading

Granite is a natural stone formed from the cooling and solidification of molten magma beneath the Earth’s surface. While granite is generally resistant to fading in sunlight, it’s essential to understand the factors that can contribute to changes in its appearance over time. Here are some considerations related to granite and potential sun fading:

  1. Color Stability: Granite comes in various colors and patterns, and each type of granite has its unique mineral composition. Some granites are more stable and resistant to color changes, while others may be more susceptible. Dark-colored granites are generally less likely to show signs of fading compared to lighter-colored ones.

  2. UV Exposure: Prolonged exposure to ultraviolet (UV) rays from sunlight can affect the appearance of certain materials, including natural stone. While granite is generally resistant to fading, prolonged exposure to intense UV rays can contribute to subtle changes in color over an extended period.

  3. Sealing: Granite countertops are often sealed during installation to protect against stains, but the sealant itself can be affected by UV exposure. Over time, the sealant may degrade due to sunlight and other environmental factors, potentially impacting the color stability of the granite. Regular resealing helps maintain the protective barrier.

  4. Weathering: Outdoor granite surfaces, such as those used for monuments or outdoor sculptures, may be subjected to weathering over time. This can include exposure to sunlight, rain, and other environmental elements, which may contribute to changes in appearance. Indoor granite surfaces, like countertops, are less likely to experience significant weathering.

Factors Leading To Sun Fading of Granite 

While granite is generally resistant to sun fading, there are certain factors that can contribute to changes in its appearance over time. Here are some key factors that may lead to sun fading of granite:

  • Mineral Composition:

The mineral composition of the granite plays a significant role in its color stability. Some granites contain minerals that are more susceptible to fading when exposed to sunlight, while others are more resistant. Dark-colored granites with a higher density of minerals like quartz and feldspar are generally less prone to fading.

  • UV Radiation:

Ultraviolet (UV) radiation from sunlight can affect the color of certain materials, including natural stone like granite. Prolonged exposure to intense UV rays can contribute to subtle changes in color over an extended period.

  • Quality of Granite:

The quality of the granite itself can impact its resistance to fading. Higher-quality granite tends to be more durable and less susceptible to changes in appearance. The porosity and density of the stone can influence how it responds to environmental factors, including sunlight.

  • Sealant Quality and Maintenance:

Granite countertops are often sealed during installation to protect against stains and other damage. The quality of the sealant used and how well it is maintained over time can affect the granite’s resistance to fading. Regular resealing helps maintain the protective barrier and ensures the longevity of the seal.

  • Environmental Exposure:

Outdoor granite surfaces, such as those used for monuments or outdoor sculptures, may be more susceptible to environmental exposure, including sunlight, rain, and temperature fluctuations. Weathering over time can contribute to changes in the appearance of the granite.

  • Cleaning Products and Chemicals:

Harsh cleaning products and chemicals can impact the color stability of granite. Acidic or abrasive cleaners can strip away the sealant and damage the stone’s surface, making it more susceptible to the effects of sunlight.

  • Artificial Lighting:

While sunlight is a primary concern, the type and intensity of artificial lighting in the area can also contribute to how granite appears. Continuous exposure to artificial light, especially certain types with UV components, may affect the color of the granite over time.

  • Geographical Location:

The geographical location of the granite installation can also play a role. Regions with high levels of sunlight and intense UV radiation may pose a higher risk of color changes compared to areas with milder climates.

It’s important to note that while some granites may experience subtle changes in appearance over time, significant sun fading is not a common characteristic of this natural stone. Proper care, including regular cleaning, sealing, and avoiding exposure to harsh conditions, can help preserve the beauty and integrity of granite surfaces. If you have concerns about the specific granite you have or its potential for fading, consulting with a professional stone specialist or installer is recommended for tailored advice.

Tips to Prevent Sun Fading

At Stone Galleria, we believe in taking proactive care that goes beyond what is usual. Our experts suggest these strategies to prevent sun fading and keep your granite surfaces in great condition:

  • Quality Sealing of Granite 

Start with a strong sealing process that forms a protective barrier against UV rays. Good sealants protect the stone from the sun, so it doesn’t change colour.

  • Stragetic Placement of Granite

Where you put your granite surfaces in your living spaces is important. Think about how the sunlight will affect their placement. Choose areas with shade or indoors to decrease direct exposure.

  • Apply UV-Resistant Film:

UV-resistant films or coatings can be applied to windows to reduce the amount of UV radiation that enters a space. While this primarily addresses the sunlight entering the room, it can indirectly help protect granite surfaces from potential fading.

  • Regular Cleaning:

Make a schedule to clean your granite regularly using cleaners that are balanced in pH. Cleaning regularly helps get rid of dirt, debris, and pollutants that can make things fade.

  • Periodic Sealing

Keep your granite surfaces protected by regularly sealing them. This step helps protect the stone from the sun’s harmful effects.

  • Use Area Rugs

Put rugs or mats on granite surfaces that get a lot of sunlight. This not only makes it look nice but also gives it extra protection.

Restoration Techniques for Sun Faded Granite

If your granite surfaces have faded from the sun, you can restore them using careful techniques.

  • Professional Polishing

Hire experts who specialise in restoring stone to make your dull granite surfaces shiny again. Polishing makes the stone look better by bringing out its colour and shine, making it look as good as it did when it was new.

  • Sealing Again

Apply a fresh coat of sealant after making the granite surfaces shiny to prevent future sun fading. Using a good sealant can help keep the restored look intact.

  • Thorough Cleaning

Clean your granite thoroughly by using special cleaners made specifically for granite. These cleaners are designed to effectively remove dirt and stains that have become deeply embedded in the surface. Deep cleaning makes the granite look better.

  • Color-Enhancing Sealers

Consider using a color-enhancing sealer that can help restore and enhance the natural color of the granite. These sealers can deepen the stone’s hues, potentially masking the effects of sun fading to some extent.


To make sure your granite lasts a long time, it’s important to know how the sun can cause it to fade. This will help you keep your stone surfaces looking beautiful. To keep your granite looking beautiful, use careful strategies like sealing it well, placing it strategically, and doing regular maintenance.
