composite decking boards

Making the most of your outdoor space is important this time of year, with summer just around the corner. If you’re looking to install some fresh new decking or bring some life back to your pre-existing setup, we’ve got the knowledge you need on how to do so. 

In this blog, we’re taking a deep dive into all things Composite Decking, covering its pros and cons, how to clean it, how to lay it and more. ***expand**

 

What Is Composite Decking? 

If you’re looking for a long-lasting decking option that also looks good, Composite Decking might just be the choice for you. Often referred to as wood plastic composite (WPC), it is made up of a blend of recycled wood fibres and plastic polymers, alongside other additives for colour, strength and texture. This combination gives composite decking several advantages over traditional materials due to its durability and cost-effectiveness. 

How To Lay Composite Decking

Looking for some tips and tricks on how to install decking yourself? We’ve put together an easy guide to laying composite decking you can follow to walk you through the process. 

Planning and Preparation

Before jumping right in, sketch out your deck design and measure your desired area accurately. It’s important to double-check with your local council to see if any permits are required first. Once you’ve got the green light, you can get started on building your deck frame, ensuring you properly level and space the joints apart (we typically recommend 1-24 inches). 

 

Decking Installation

Now comes the fun part- laying the composite boards! 

Start by attaching starter clips along the frame's outer edge and securing them with screws. Place the first board facing up with the desired side, leaving a small overhang. 

After this, pre-drill and screw the board securely to the joists. Next, slide hidden fastener clips into the grooves of the first board and partially tighten them. Slide the subsequent board's groove over the clips and repeat the process.

Once the next board is secure, go back and fully tighten the screws on both boards. Continue laying the boards one by one, following these steps until your deck is complete!

 

Finishing Touches 

The final step is adding those finishing touches that elevate your deck's look and functionality. Then to finalise your decking measurements cut the final board size and then secure it with screws. Install fascia boards along the perimeter for a polished look. 

Finally, using a Composite Decking Cleaner or warm water and a squeeze of dish soap, give your newly installed decking a once over following the manufacturers' instructions.

How To Clean Composite Decking 

The main benefit of composite decking is its low maintenance requirements. However, to keep your decking looking good and lasting, regular cleaning is still required. To keep you on track, here’s a simple step-by-step cleaning routine you can follow: 

1. Preparation: Start by removing any furniture, planters, or decorations from the deck.

 

2. Clear Debris: Sweep away leaves, dirt, and loose debris with a broom.

 

3. Wet the Deck: Attach a spray nozzle to your hose and thoroughly soak the entire deck surface.

 

4. Mix Cleaning Solution: Fill a bucket with warm water and add a squirt of dish soap. Alternatively, you can use a specialised composite deck cleaner as per the manufacturer's instructions.

 

5. Scrub and Rinse: Dip a soft-bristled brush into the soapy water and scrub the deck in sections, working along the grain of the boards to remove dirt from the grooves. Rinse each section with clean water from the hose as you go.

 

6. For Stubborn Stains: To treat mildew or mould, create a solution of one tablespoon each of lemon juice and baking soda, mixed with a quarter cup of white vinegar in water. Apply the solution with a brush and rinse thoroughly.

 

7. After Cleaning: Allow the deck to dry completely before using it again and placing back any furniture or accessories.

Maintenance Tips:

Here are some additional tips to keep your composite deck looking its best for years to come:

  • Regularly sweep your deck to prevent dirt buildup.
  • Clean your deck at least once a year, or more often in high-traffic areas.
  • Avoid using harsh chemicals or abrasive cleaners on your composite deck.

How Long Does Composite Decking Last?

Composite decking boasts incredible durability. With proper care, it can last an impressive 25 to 50 years. That's significantly longer than traditional wood decks, which typically only see 10 to 15 years of service. This translates to less time spent on replacements and repairs, and more time enjoying your outdoor space.

Pros and Cons of Composite Decking

Pros: 

  • Low Maintenance: Unlike wood, composite decks require minimal upkeep. No more constant staining, sealing, or sanding – just a simple cleaning routine to keep your deck looking its best.

 

  • Durability: Composite decking is exceptionally resistant to rot, warping, and insect damage. This translates to a longer lifespan compared to traditional wood and less money spent on replacements down the line!

 

  • Style Options: Gone are the days of limited decking choices. Composite decking comes in a wide variety of colours and textures, mimicking natural wood grains or offering a modern, sleek look. You can find options to complement any design style, from classic and rustic to contemporary and minimalist.

 

  • Safety: Many composite decks offer excellent slip resistance, a crucial factor for areas around pools or patios. This provides peace of mind, especially for families with young children or pets.

 

  • Environmentally Friendly: While some composite materials contain plastic, many manufacturers are increasingly using recycled materials in their production process. This reduces environmental impact compared to traditional wood decking, which requires constant chemical treatment.

 

Cons: 

  • Higher Cost: Composite decking generally has a higher upfront cost compared to wood. This can be a significant factor depending on the size and complexity of your deck design.

 

  • Feel: While some composite options mimic wood grain very well, they may not feel as natural underfoot. The texture can be smoother and cooler than real wood, which some homeowners might find less desirable.

 

  • Heat Absorption: Some composite materials can absorb more heat than wood, particularly darker colours. This can make the deck uncomfortably hot to walk on in direct sunlight, especially in hot climates. Opting for lighter colour options can help mitigate this issue.

 

  • Fading: Although many composite decks are UV resistant, some colours may fade slightly over time. This is a natural process, but choosing higher-quality composite materials with superior fade resistance can help minimise this effect.

 

  • Weight: Composite decking can be heavier than traditional wood. This might be a factor during installation, particularly for larger decks or those built on a second story.
