Build your whole deck around our light grey boards here. The calculator walks you through each part, from subframe and joists to clips, starter clips, fascia and edging trims. Enter your length and width in metres and skip any step for parts you already have. Light grey is most often ordered as the lighter half of a two-tone deck with a dark grey. If that’s your plan, use the manual selection in the calculator so the two colours don’t get mixed in one order. If light grey is the whole deck and you want it to stay pale, bear in mind that light colours show weathering more than dark ones. Our wood grain boards is worth comparing: it’s designed to settle into a mid grey after around six months, so what you see then is what you keep.

Expert Advice On Our Light Grey Composite Decking
Want to know more? Our in-house expert, Allan, gives his take on our Light Grey Composite Decking, and we’ve selected some of our best guides to help you decide if this is the right choice for you.
A Word from Our Expert, Allan Jeffrey BSc. Eng. (Hons), Composite Materials Specialist, Environmentalist, and CEO of Ultra Decking:
Our Light Grey decking was created for one simple reason: our customers asked for it. Many were looking for a cooler, calmer aesthetic for their garden, and this shade delivers that effortlessly.
It also has a significant practical advantage: it absorbs far less heat on sunny days compared to darker boards. This makes it much more comfortable underfoot and an outstanding choice for families with pets and children.
Beyond its family-friendly appeal, we also designed it to be the perfect partner for our darker boards. It’s fantastic for creating stylish ‘picture frame’ borders or high-contrast patterns when used alongside a colour like Anthracite Grey. Of course, it’s all built on our enhanced surface technology, so you get that same great colour retention and durability.

Quick Calculator: How Many Light Grey Boards Do You Need?
You may already have your build planned out. If so, our quick calculator works out just the boards you need, with recommended accessories like our trims listed below so you can add them if needed. If you’re using light grey as the contrast in a picture frame or a horizontal lay, don’t order extra light grey boards for the edging. Use our anthracite grey bullnose boards or grey wood grain bullnose boards instead — they’re built for the wear a deck edge takes over its life, and the darker edge frames the light grey well.

FAQ About Our Light Grey Decking
1 Will the light grey boards fade over time?
Yes, like all composite products, some fading will occur due to UV exposure, typically around 25% on this shade. Our upgraded formulation reduces early fading, and once the board has settled into its softer tone it holds from then on. Bear in mind that light colours show the fade more noticeably than dark ones..
2 Can I install this light grey decking myself?
Yes. With side grooves for our hidden fastener system, you don’t need specialist tools or experience, and our installation guide walks through each step. Most customers find it a satisfying DIY project.
3 Is the light grey colouring safe for pets and children?
Yes. Our light grey composite is splinter-free, cooler underfoot than darker boards and metal alternatives, and offers good traction, making it safe for little feet and paws alike.
4 Are your light grey boards, really low maintenance?
Yes. No sealing, no staining, just occasional cleaning with soap and water. It’s well suited to busy households.
5 Does light grey decking show dirt more than darker colours?
A little. Muddy footprints and paw prints show more on a pale board than on a mid or dark grey, though they wash off with soapy water. If your deck takes heavy traffic from pets or children, a mid grey hides everyday marks better; if you want the bright, airy look, light grey is worth the occasional rinse. Our guide to choosing a decking colour covers the trade-off.
6 How many light grey boards will I need?
Use the quick calculator on this page: enter your deck’s length and width for a board count, and tick the 5% cutting margin to cover trimming and cuts. Each 3.6m board covers roughly 0.54 m². If light grey is only the border of a two-tone deck, count just the border boards here.
7 What makes Light Grey a popular choice?
Light grey is a versatile, modern shade that works in both sunny and shaded spaces. It pairs well with stone, glass, greenery and minimalist furnishings, and it is the colour most often chosen as the lighter half of a two-tone deck with anthracite grey.
