Does Composite Decking Fade Over Time?

One of the most common questions homeowners ask when choosing composite decking is: Does it fade? While all outdoor materials are exposed to the elements, high-quality composite decking like BuildDeck’s is engineered for long-term colour stability and performance. In this guide, we’ll explain why some composite decking may fade, how BuildDeck products resist fading, and what you can do to ensure your decking looks great for years to come.

Why Does Fading Happen?

Fading is typically caused by prolonged exposure to UV rays, moisture, and temperature fluctuations. Traditional timber decking is particularly prone to fading, warping, and weathering, which is why many people are turning to composite alternatives.

Composite decking boards made from a blend of wood fibres and recycled plastics are far more resistant to fading — especially capped composite decking, which includes a durable outer layer for added UV protection.

BuildDeck’s Fade-Resistant Technology

At BuildDeck, we use advanced co-extrusion technology to create fade-resistant composite boards that retain their colour and finish, even after years of outdoor exposure.

Key features of our decking products include:

  • UV-resistant outer shell (on capped ranges)

  • Minimal colour change over time

  • Low-maintenance finish – no sanding, staining, or sealing needed

  • Tested for long-term outdoor use in the UK climate

What Level of Fading Can You Expect?

While all decking materials may experience a small degree of weathering, BuildDeck composite boards fade less than 5% in colour tone over time — a barely noticeable change.

Uncapped composite boards (such as some entry-level options) may see more noticeable fading in the first 3–6 months as they adjust to their environment. However, this is a natural weathering process and will stabilise thereafter.

How to Protect Your Decking from Fading

Although BuildDeck products are engineered to last, here are a few tips to keep your deck looking its best:

  • Clean regularly with mild soap and water (care guide here)

  • Avoid prolonged contact with harsh chemicals or solvents

  • Use mats under grills or fire pits to avoid heat damage

  • Consider shaded or partially covered areas for added protection

Composite vs Timber: Fading Comparison

Traditional wood decking needs regular treatment to avoid fading, splintering, and rot. In contrast, composite decking offers long-term visual appeal with minimal upkeep.

Feature Timber Decking Composite Decking
Fades Over Time Yes – significantly Minimal (<5%)
Requires Staining Every 1–2 years No
UV Resistance Low High
Maintenance Level High Low

Composite decking Colour Fade expectancy

Builddeck Composite Decking products are made from 60% natural material and each board is designed to imitate traditional timber, often with naturally occurring variations in colour, texture and grain pattern. The boards are designed to weather and fade slightly to allow the colour to settle evenly over time. Slight variations may also occur when ordering from different batches, at different times. We strongly advise providing our team with as much detail as possible as to your measurements, design and additional requirements to allow us to provide the most accurate quantity initially, and avoid any possible batch variations. Please see our composite decking maintenance page for information on keeping your decking clean and free from fallen pollen and dust.
