Understanding Composite Decking:

Composite Decking


Understanding composite decking involves familiarizing yourself with its composition, benefits, drawbacks, installation process, maintenance requirements, and comparison to other decking materials. Let’s delve into each aspect:

Composition: Composite decking is a blend of recycled wood fibres or sawdust and plastic materials, typically high-density polyethene (HDPE), polypropylene, or PVC. The combination of these components creates a durable, weather-resistant, and low-maintenance decking material.

Benefits of Composite Decking:

  • Composite decking is highly resistant to rot, decay, insects, and fading, making it ideal for outdoor use.
  • It requires minimal upkeep compared to wood, with no need for staining, sealing, or sanding.
  • Composite decking comes in various colours, textures, and styles, mimicking the appearance of natural wood.
  • It has a longer lifespan than traditional wood decks, reducing the need for frequent replacements.
  • By using recycled materials, composite decking contributes to sustainability and reduces demand for new lumber.

Drawbacks of Composite Decking:

  • Composite decking can be more expensive upfront than some wood options, though it often balances out due to lower maintenance costs.
  • In direct sunlight, composite decking can get warm, but many manufacturers work to reduce heat absorption in newer products.

In summary, composite decking offers a durable and low-maintenance alternative to traditional wood decks. Its blend of recycled materials, attractive appearance, and sustainability make it a popular choice for outdoor spaces. Understanding its composition, benefits, drawbacks, and installation process will help you make an informed decision when considering composite decking for your home or project.

Duration of Composite Decking?

The duration or lifespan of composite decking can vary based on several factors, including the quality of the product, the manufacturer’s warranty, the climate and weather conditions in your area, and the level of maintenance it receives. In general, composite decking is known for its longevity and durability compared to traditional wood decks.

A well-maintained composite deck can last anywhere from 25 to 30 years or even longer. Some high-quality composite decking products come with warranties that extend up to 25 years or more, which reflects the confidence manufacturers have in their products’ durability.

To maximize the lifespan of your composite deck, consider the following factors:

  • Quality
  • Maintenance
  • Climate
  • Installation
  • Avoiding Damage

By following these guidelines and choosing a high-quality composite decking product, you can expect your deck to provide a long-lasting and beautiful outdoor space for many years to come.

Can you power wash composite decking?

Yes, you can power wash composite decking, but it’s essential to do so with caution and follow the manufacturer’s guidelines. Power washing can be an effective way to remove stubborn dirt, stains, and debris from the surface of your composite deck.

Here are some tips for power washing composite decking safely:

  • Check the Manufacturer’s Recommendations: Before using a power washer, review the care and maintenance guidelines provided by the manufacturer of your composite decking. Some manufacturers may advise against using high-pressure power washers, while others may have specific recommendations for pressure settings and nozzle types.
  • Use a Low-Pressure Setting: If the manufacturer approves power washing, use a pressure washer with a low-pressure setting. A pressure setting between 1500 to 2000 psi (pounds per square inch) should be sufficient for most composite decking materials. High-pressure settings can damage the surface and void warranties.
  • Maintain a Safe Distance: Keep the pressure washer nozzle at a safe distance from the deck surface, usually around 12 to 18 inches. Holding the nozzle too close can cause damage to the composite material.
  • Angle the Spray: Direct the spray at a downward angle to prevent lifting or splintering the deck boards.
  • Test in a Hidden Area: Before starting, test the pressure washer in an inconspicuous area of the deck to ensure that the pressure setting and technique do not cause any damage.
  • Avoid Focusing on One Spot: Keep the pressure washer moving to avoid concentrating the spray on a single spot for too long, which can cause damage.
  • Cleaning Solution: For tough stains, consider using a composite deck cleaner along with the power washer. Always use a cleaner recommended by the manufacturer and follow the instructions carefully.
  • Rinse Thoroughly: After power washing, rinse the deck thoroughly with clean water to remove any remaining detergent or debris.

Remember that while power washing can be effective, it is not always necessary for regular maintenance. Most of the time, composite decking can be adequately cleaned with mild soap, water, and a soft-bristle brush or a regular garden hose. Power washing should be reserved for tougher stains or deep cleaning when other methods prove ineffective. Always prioritize the preservation of your deck’s appearance and structural integrity by using the appropriate techniques and adhering to manufacturer recommendations.
