Welcome to another edition of our “Decking Deep Dive” series.

Today, we explore a common maintenance question among homeowners considering composite decking: Can it be sanded?

Understanding the different types of composite decking and their maintenance requirements is crucial for making the right choice for your outdoor space.

What is Composite Decking?

Composite decking is a blend of wood fibres and plastic materials that create a durable, long-lasting board.

There are two main types: uncapped and capped composite decking. While uncapped composite can be sanded, it lacks the additional protective layer found in its capped counterparts.

At WoodEvo, we focus on capped composite decking due to its superior durability and performance.


Can Composite Decking Be Sanded?

The answer varies by type. Uncapped composite decking can technically be sanded; however, this is not the case with capped composite decking. The latter features a protective polymer shell that is designed to resist weathering, staining, and fading, and this capping prevents the possibility of sanding.

Why Capped Composite Decking Does Not Support Sanding


Capped composite decking is engineered for maximum longevity and minimal maintenance. The protective cap, which covers the core of the decking board, is not designed to be penetrated by sanding. Sanding would remove this layer, exposing the underlying material and compromising the board’s structural integrity and aesthetic appearance.

The Drawbacks of Uncapped Composite Decking

While uncapped composites offer the possibility of sanding, they generally require more maintenance. These boards are more vulnerable to staining, fading, and moisture penetration, which can lead to a shortened lifespan and increased care requirements. Due to these factors, WoodEvo does not sell uncapped composite decking, preferring to offer products that provide the greatest value and satisfaction.


Maintenance Tips for Capped Composite Decking

Maintaining capped composite decking is straightforward:

  • Cleaning: Regular cleaning with soap and water will keep your deck looking new.
  • Stain Removal: For tough stains, use a cleaning product made specifically to be used on composite decking products.
  • Scratch Repair: Minor scratches can often be blended into the surrounding area with a heat gun, but always consult manufacturer guidelines first.

Choosing the Right Composite Decking for Your Needs

When selecting decking, consider the climate of your area, the level of maintenance you are willing to undertake, and the aesthetic qualities you desire. Capped composite decking, although higher in initial cost, offers significant savings over time with reduced maintenance and superior durability, particularly suited to the climates of Melbourne and Sydney.



Capped composite decking offers a high-value, low-maintenance alternative to traditional wood and uncapped composite materials. It does not require sanding, and its care is simple, focusing on preservation rather than intensive maintenance.

For homeowners looking for long-term beauty and durability, capped composite decking from WoodEvo is an excellent choice. Explore the possibilities with us and see how your outdoor living space can transform with the right materials.
