Does quartz fade in sunlight?
Quartz countertops intended for indoor use can fade under prolonged exposure to direct sunlight but this typically only happens when such countertops are used outside. Natural light entering your home through a window is much less likely to produce this effect unless it lands directly on your countertops for extended periods.
The degree to which sunlight discolors quartz countertops will vary depending on factors such as:
- the quality of quartz and pigments used (check out this page to learn why our countertops at Caesarstone are considered the highest quality)
- the quartz countertop’s color
Understanding the Impact of Sunlight on Quartz
Quartz countertops are composed of roughly 90-95% natural quartz crystals, combined with resins, pigments, and other materials. While quartz is naturally tough, the resin and pigments used to bind it can be sensitive to UV rays from sunlight. Exposure to these UV rays over a long period can cause fading or discoloration, with some parts of the quartz taking on a yellowish tint or losing their vibrancy.
This effect is more noticeable in rooms where quartz is exposed to direct sunlight through windows or skylights, such as in sunny kitchens, bright bathrooms, or outdoor living spaces. Thankfully, there are several ways you can protect your quartz countertops and keep them looking as beautiful as the day they were installed.
Why does quartz fade in the sun? A quick science lesson
The culprit is UV rays, which bleach just about any pigmented surface. This effect isn’t limited to quartz. Any material – including granite and marble – will fade in sunlight if it hasn’t been rated specifically for UV exposure.
Here’s a quick rundown of the science behind UV rays and surface discoloration.
Ultraviolet light is a type of electromagnetic radiation. It’s an ionizing force capable of causing chemical reactions such as:
- fading the paint on cars
- making plastics and other materials (including some natural stones) brittle
- causing materials to crack
Standard windowpane glass mitigates some of these effects. This is why, for instance, transition lenses won’t activate while you’re driving. It’s also why sunlight typically won’t damage your indoor quartz countertop.
Factors Affecting Quartz Fading
Exposing quartz to sunlight for prolonged periods can contribute to its fading over time. One of the main factors that lead to quartz fading is the effects of UV radiation. UV radiation, which is present in sunlight, can cause the color pigments in quartz to break down and fade. This is why it is important to protect your quartz surfaces from direct sunlight, especially in areas with high UV exposure. In addition to UV radiation, there are also environmental factors that can affect the color retention of quartz.
For example, exposure to harsh chemicals, such as bleach or ammonia, can cause the color to fade. Similarly, high levels of humidity and moisture can also contribute to fading. To ensure the longevity of your quartz surfaces, it is important to take these factors into consideration and implement protective measures.
Preventive Measures for Quartz Fading
How can you effectively protect your quartz surfaces from fading in sunlight? Here are some preventive measures you can take to safeguard your quartz countertops and other surfaces from sunlight damage:
- Use window coverings: Install blinds, curtains, or shades to control the amount of sunlight entering your space. This will help minimize direct exposure to UV rays and reduce the risk of fading.
- Apply UV protection film: Consider applying a UV protection film to your windows. This film acts as a barrier, blocking harmful UV rays from reaching your quartz surfaces.
- Keep surfaces clean: Regularly clean your quartz surfaces using a non-abrasive cleaner and a soft cloth. This will remove any dirt or debris that may contribute to fading and ensure your countertops maintain their original shine.
Does this mean you shouldn’t use quartz for your countertops?
Absolutely not! As we discuss on this page, quartz is the best countertop material for a variety of reasons. It offers durability, and resistance to stains, bacteria, and scratches, that other materials don’t.
You can buy quartz designed to resist fading from sunlight. Our Outdoor Collection is perfect if your sunlight-related concerns stem from plans to create a patio.
Even if you’re looking for an indoor countertop material, rest assured that quartz is more than capable of withstanding the UV exposure found in most homes. At Universal Quartzz, we’ve spent more than 30 years perfecting our countertops and a proprietary blend of quartz and pigments. Our customers enjoy their surfaces for many, many years.
Sunlight’s ability to fade quartz countertops is often exaggerated by manufacturers specializing in other materials (namely natural stones such as granite and marble). The reality is that, as mentioned earlier, extensive exposure to UV rays will damage any surface not rated for outdoor use.
Tips to Protect Quartz Countertops from Sunlight
Install UV-Blocking Window Films
One of the most effective ways to reduce UV exposure is by installing UV-blocking window films. These films can block up to 99% of harmful UV rays, protecting both your countertops and other furniture from sunlight damage. Window films are easy to apply, relatively affordable, and can significantly reduce the impact of sunlight on your quartz surfaces while still allowing natural light to enter your space.
Use Curtains or Blinds
Another straightforward solution is to use curtains, blinds, or shades. If your quartz countertop is in direct line with a window, using curtains or blinds can help shield the countertop from excessive sunlight. Sheer curtains allow natural light to filter in while diffusing and reducing the intensity of direct sunlight. For added convenience, motorized blinds can be installed, allowing you to easily adjust them to block or allow sunlight throughout the day.
Apply Protective UV Coatings
There are specialized UV-resistant coatings that can be applied to quartz countertops to help prevent fading or discoloration caused by sunlight. These coatings are typically clear and work by blocking the harmful UV rays from penetrating the surface. This option can be ideal for countertops in high-sunlight areas, such as kitchens that receive intense afternoon sun or outdoor kitchen countertops. Always consult a professional to ensure the right product is chosen for your quartz surface.
Use Shades or Awnings in Outdoor Areas
If you have quartz countertops in an outdoor kitchen or patio area, it’s crucial to provide protection from direct sunlight. Installing a shade structure, such as a pergola, awning, or canopy, can help keep the countertops out of direct sunlight, preventing UV damage. These structures can also provide a comfortable environment for you and your guests, creating shaded areas to relax and entertain.
Rearrange Décor to Minimize Sun Exposure
Consider arranging decorative items such as bowls, small appliances, or potted plants on areas of your quartz countertop that receive the most sunlight. These items can act as a natural barrier between direct sunlight and your quartz, helping reduce the risk of discoloration. Just make sure not to leave heavy objects in place for extended periods, as they can leave marks on the surface. Regularly moving these items around will ensure even wear and tear.
Regularly Monitor the Countertops
Keeping an eye on your quartz countertops is one of the best ways to protect them from sunlight damage. Regularly inspect the surfaces for any signs of fading, discoloration, or weakening. If you notice that the surface is beginning to fade, it may be time to increase your protective measures, such as adding UV-blocking window film or applying a UV-resistant coating.
Consider Quartz Placement During Installation
Prevention starts with planning. If you’re installing new quartz countertops, consider their placement in relation to windows and skylights. Avoid placing quartz directly under windows or areas that receive intense, direct sunlight. If this cannot be avoided, then use a combination of protective measures, such as window films and coverings, to help reduce sun exposure. A strategic approach during installation can make a significant difference in the long-term preservation of your quartz surfaces.
Choose the right quartz
When building an outdoor patio or kitchen, use quartz rated for that specific purpose. In addition to withstanding UV rays, such quartz will hold up against more extreme temperatures and elements than what would occur indoors.
Monitor your quartz countertops for signs of discoloration
Quartz countertops are very durable. They’re not indestructible though. As part of your maintenance routine, inspect your quartz countertops for discoloration or any other damage.
If you notice discoloration, start by ruling out other potential causes such as:
- spills
- improper cleaning (i.e. using acidic products, which can cause etching)
- placing hot pots and pans directly on the countertop
- cutting produce directly on the countertop
- particularly hard water in your kitchen, which can cause limescale
Check out this page for some tips on taking care of your quartz countertops, including which products to use for everyday cleaning and stain removal.
If you’ve ruled out these other factors and have reason to believe sunlight is the culprit, refer back to the first tip and consider installing blinds that will shield your quartz countertop during peak sunlight hours.
