Does composite decking fade in the sun?

Yes, composite decking can fade over time due to prolonged UV exposure, although modern materials are designed to resist fading better than traditional wood.

Can you seal composite decking?

Some composite decking products can be treated with UV-protective sealants, but it is important to use products recommended by the manufacturer.

How do you prevent composite decking from fading?

Prevent fading by cleaning regularly, minimizing direct sun exposure with shade structures, and using UV-resistant products when appropriate.

Is composite decking better than wood for sun exposure?

Composite decking generally performs better than wood in sun exposure because it is more resistant to fading, cracking, and moisture damage.

The Best Ways to Protect a Composite Deck from Harsh UV Rays

Composite decking is widely known for its durability, low maintenance, and long lifespan, making it a popular choice for homeowners. At BOS Home Exterior LLC in Virginia Beach we offer durable Trex® brand composite decks for our deck installations. Trex® composite decking options provide you with strong easy to maintain patio decking made from 95% recycled materials. Composite decks have a surface that is resistant to cracking and splitting and maintain their stunning look, without the need for re-staining, but even composite materials can be affected by prolonged exposure to harsh UV rays. Over time, sunlight can cause fading, surface damage, and heat buildup. Fortunately, there are several effective ways to protect your composite deck and keep it looking great for years to come.

Why UV Protection Matters for Composite Decking

While composite decking is designed to be more resistant to the elements than traditional wood decking, it is not completely immune to sun damage. Constant exposure to UV rays can cause fading or discoloration, especially in darker-colored boards. UV rays can also dry out the surface over time, which may lead to minor cracking or surface wear.

Protecting your composite deck from UV exposure helps:

Maintain the original color
Prevent surface deterioration
Reduce heat retention
Extend the lifespan of your deck
Preserve your home’s curb appeal

6 Tips to Help Protect Your Composite Deck from UV Rays

Apply a UV-Resistant Protectant

Not all composite decks require sealing, but many manufacturers recommend using a UV-resistant protectant to help minimize fading and sun damage. These products are designed specifically for composite materials and help create a protective barrier against the sun’s rays. Reapply your UV protectant every 1–2 years (if applicable).

Install Shade Structures

One of the most effective ways to reduce UV exposure is to simply add shading to your deck. Shade structures not only protect your deck from debris and leaves but also make the space more comfortable and enjoyable during hot summer months.

Popular shade options from BOS Home Exterior LLC include:

Pergolas
Awnings
Shade sails
Covered porches
Large patio umbrellas

Clean Your Deck Regularly

Dirt, pollen, and debris can trap heat and further contribute to surface wear. Regular deck cleaning ( 2–3 times per year) helps maintain the protective outer layer of the composite boards and prevents buildup that can make UV damage worse. When cleaning your deck be sure to use a mild soap and water combination, soft bristle brush, and a garden hose (avoid pressure washing too close to the decks surface) and get into the habit of checking for any fading or wear when cleaning your composite deck.

Use Outdoor Rugs and Furniture Strategically

Outdoor rugs and furniture can also help block direct sunlight from hitting certain areas of your composite deck. These additions can reduce uneven fading and protect high-traffic areas from both sun exposure and wear.

*BOS Pro Tip: Rotate rugs and furniture occasionally to prevent uneven color changes.

Choose Lighter Deck Colors

If you are installing a new composite deck, consider choosing lighter colors. Lighter colors reflect more sunlight and absorb less heat, which helps reduce UV-related wear and keeps the deck cooler to walk on.

Avoid Harsh Chemicals

Some chemical cleaners can damage the protective outer layer of composite decking, making it more vulnerable to UV damage. Always use cleaners that are specifically designed for composite decking materials.
