Grey Composite Decking: Why You Should Consider it for Your Outdoor Space

Grey composite decking offers a seamless combination of style, durability and low maintenance—the epitome of modern outdoor living. Perfect for creating an elegant and contemporary outdoor space, grey composite decking products deliver a sleek finish that complements a variety of home and garden designs.

Benefits of Choosing Grey Composite Decking:

Stylish and Modern: Whether you’re aiming for a light and airy space or a more industrial look, grey hues bring a sophisticated, minimalist aesthetic that works well with both traditional and modern gardens.

Versatile Design Options: Our grey decking is also an incredibly versatile material. It can be used as cladding or as fencing battens, or even to create a balcony bench design. Available in a range of finishes, from sleek and smooth to rustic and textured, it gives you the look that best suits your garden. It pairs beautifully with different materials like glass, metal and stone, offering endless design possibilities.

Durability and Strength: Unlike traditional wood, composite decking has been engineered to withstand all weather conditions. Whether it’s hit by heavy rain, snow, or direct sunlight, composite decking will not fade, warp, or crack like natural timber decking. It is resistant to moisture, UV rays and temperature changes, making it a reliable choice for the unpredictable UK climate and perfect for year-round use.

Low Maintenance: One of the biggest benefits of composite decking is its ease of care. There's no need for staining, sealing or extensive cleaning. A quick rinse and brush down are often all that’s required to keep it looking like new.

Slip-Resistance: Safety is always a priority, and composite decking features slip-resistant surfaces, making it an excellent choice for poolside areas or families with children.

Eco-Friendly: Across our range of composite decking, all boards are manufactured with sustainability in mind. Brushed and Grooved decking is produced in part with natural bamboo fibres, while DesignBoard Decking is part-made with rice husks, which are a natural waste product of rice-milling. Check out Millboard Composite Decking’s sustainable practices.

Cost-Effective Over Time: The initial cost of composite decking may be higher than wood. However, its longevity and minimal upkeep make it a more cost-effective option in the long run, as you won’t need to worry about constant repairs or replacements.

Installation Hints and Tips:

Prepare the Ground: Clear the area and ensure the ground is level. For elevated decks, a subframe of treated timber or composite joists is necessary to support the decking.

Install Joists: Joists should be spaced evenly, usually 300mm apart. This framework provides the support for your decking boards.

Fix the Boards: Use the recommended fixing clips and screws, such as the DesignBoard Clip System, which ensures a seamless and secure fit. View deck building essentials.

Cutting the Boards: Composite boards can be cut using standard woodworking tools, such as a bench-mounted drop saw with a carbon-tipped blade. Read more on cutting composite decking.

Edging: For a polished finish, use matching fascia boards or bullnose boards for exposed edges or steps.

Maintenance: One of the main benefits of composite decking is its low-maintenance nature. Simply sweep away debris and wash with water and mild soap if necessary.

Grey Composite Decking FAQs

• DesignBoard Classic – 10 years

Is composite decking slippery? 

Composite decking is designed with slip-resistance in mind. Ranges like Millboard and DesignBoard Grooved offer textured surfaces for enhanced grip, making them safe for use around pools or in wet conditions. 

Can composite decking fade in sunlight? 

UV-resistant properties in both Millboard and DesignBoard prevent significant fading, ensuring that your decking remains vibrant for years. 

Can I put a fire pit or fire bowl onto my composite decking?  

This depends upon the heat exposure and type of firepit that you are intending on installing. We would always recommend there is a gap to the underside allowing for a good airflow to prevent a build-up of heat under any type of burner. Refer to our DesignBoard Product Guide for more information. 

How do I clean composite decking? 

Like any outdoor material, composite decking does require maintaining, to keep it looking its best and to ensure it lasts. Cleaning is a straightforward process. Depending on how clean you wish to keep your deck, it usually takes place seasonally. Sweep regularly and hose down with water. For stubborn dirt, use a mild detergent and a soft brush. To remove stains, specialist cleaning products can be used, but check with the manufacturer’s guidelines before applying any chemicals to your decking, and always test cleaning products in a small, inconspicuous section, before applying to the whole decked area.
