How to Maintain and Care for Your Composite Decking

Composite decking is becoming an increasingly popular choice for outdoor living spaces across Melbourne. With its combination of wood fibres and plastic, it provides the perfect blend of durability, aesthetics, and minimal maintenance. However, like any outdoor surface, composite decking still requires care to ensure it stays looking great and performs well over time.

In this blog, we’ll share some essential tips for maintaining and caring for your composite decking in Melbourne’s unique climate. Whether you’re dealing with heat, humidity, or occasional downpours, we’ve got you covered.

What is Composite Decking?

Before we dive into maintenance tips, it’s worth understanding what composite decking is. Unlike traditional timber decking, which can warp, splinter, or require constant sealing, composite decking is made from a mix of recycled wood fibres and plastic. This results in a highly durable, low-maintenance decking solution that is resistant to weather, rot, and pests.

Composite decking is also designed to mimic the look of natural wood, so you can achieve that classic wooden deck aesthetic without the hassle of upkeep. In Melbourne, where the weather can range from hot summers to wet winters, composite decking provides a resilient outdoor flooring option. Explore WPC decking boards products:

Why is Regular Maintenance Important?

Even though composite decking is low-maintenance compared to traditional timber, it still requires some care to extend its life and preserve its appearance. Regular maintenance ensures that your deck:

Remains safe and slip-resistant
Retains its colour and beauty
Lasts for many years without needing replacement
Stays free of dirt, debris, and mould

Maintaining your composite deck helps you avoid costly repairs down the track and ensures it’s always ready for entertaining, relaxing, or enjoying the Melbourne outdoors.

1. Clean Your Deck Regularly

One of the most straightforward ways to maintain your composite decking is by cleaning it regularly. Dust, dirt, and leaves can accumulate over time, and if left unchecked, they can cause staining or encourage mould growth. Here’s how to clean your deck:

How to Clean Composite Decking

Sweep the Deck – Start by sweeping the surface to remove loose dirt and debris. This will prevent any particles from scratching the surface during the cleaning process.
Wash with Soapy Water – For general cleaning, a mixture of warm water and mild soap is sufficient. Use a soft-bristled brush or cloth to scrub the surface. Avoid harsh cleaning agents that could damage the composite material.
Rinse Thoroughly – Once you’ve scrubbed the surface, rinse the deck with clean water to remove any soap residue. A pressure washer on a low setting can also be used, but make sure you don’t get too close to avoid damaging the surface.
Address Stubborn Stains – If you encounter stubborn stains, such as oil or wine spills, a specially designed composite deck cleaner can be used. Always follow the manufacturer’s instructions.

Cleaning Frequency

In Melbourne, where the climate can fluctuate between dry heat and humid conditions, it’s essential to clean your composite deck every 2-3 months. If your deck is in an area with lots of trees, you might need to clean it more often due to the accumulation of leaves and sap.

2. Keep the Deck Free of Debris

Leaves, branches, and other debris can easily accumulate on your composite decking, especially during autumn. Not only does this make your deck look messy, but it can also cause damage over time.

How to Prevent Damage from Debris

Regular Sweeping – As mentioned earlier, sweeping your deck regularly is one of the simplest and most effective ways to keep it free of debris.
Remove Stubborn Debris – Don’t let leaves or twigs sit on your deck for extended periods. They can trap moisture, which may cause mould or mildew to form.
Trim Trees and Shrubs – If you have trees or shrubs near your deck, make sure to trim them back to reduce the amount of debris falling onto the surface.

3. Protect the Deck from the Elements

Melbourne’s weather can be unpredictable, with periods of intense sun, heavy rain, and even hail. While composite decking is weather-resistant, it’s still a good idea to take steps to protect your deck from extreme conditions.

Sun Protection

Use a Deck Cover – If your deck is exposed to the harsh midday sun, consider using a deck cover to protect it from UV damage. This will help prevent the material from fading or discolouring over time.
Furniture Pads – When placing furniture or planters on your composite deck, use protective pads underneath them. This will help distribute the weight and prevent indentations or scratches.

Rain and Moisture

Rinse After Rain – After a rainstorm, make sure to rinse your deck to remove any dirt or moisture that could get trapped in the surface.
Install Gutters or Drainage – To prevent water from pooling on your deck, ensure that your outdoor space has proper drainage or gutters installed. This will prevent moisture from seeping into the composite material and causing damage.

4. Inspect and Maintain Fasteners

Over time, the screws and fasteners that hold your composite decking in place may loosen or corrode. It’s important to inspect them regularly to ensure your deck remains stable and safe.

Fastener Inspection and Maintenance

Check for Loose Screws – Periodically check the screws or nails holding your decking boards together. Tighten any that have become loose, and replace any corroded fasteners with stainless steel or corrosion-resistant alternatives.
Seal or Replace Damaged Boards – If you find any cracked or warped boards during your inspection, it’s important to replace them as soon as possible to prevent further damage.

5. Address Mould and Mildew Growth

In Melbourne’s humid climate, composite decking can sometimes develop mould or mildew, especially in shady, damp areas. Mould not only affects the appearance of your deck but can also cause slippery surfaces, creating safety hazards.

Preventing Mould and Mildew

Regular Cleaning – Regularly cleaning your deck and keeping it free of debris will help reduce the chance of mould and mildew growth.
Use Mould Cleaner – If you notice mould or mildew, use a specialised composite deck cleaner or a solution of vinegar and water to scrub the affected areas. Always follow the manufacturer’s guidelines.
Ensure Good Ventilation – Mould thrives in areas with poor air circulation. To help prevent growth, ensure that your deck is well-ventilated by trimming nearby plants and allowing airflow beneath the decking.

6. Seasonal Care Tips for Melbourne’s Climate

Melbourne’s weather can change dramatically throughout the year, so adjusting your decking care routine seasonally is important.

Summer Care

In summer, Melbourne can experience intense heat. To prevent heat-related damage, keep your deck cool by regularly cleaning and protecting it from the sun.

Winter Care

During the wetter months, make sure to remove any debris quickly to prevent water from being trapped on the deck. It’s also a good idea to clear gutters and ensure proper drainage around your deck.

Conclusion

Caring for your composite decking in Melbourne doesn’t need to be difficult. With regular cleaning, protection from the elements, and a few seasonal adjustments, your deck will remain in top condition for years to come. By following these simple maintenance tips, you can enjoy your outdoor space without the stress of constant repairs or upkeep.
