Build your whole cladding project around our smooth anthracite grey boards here. Enter each wall’s width and height in metres and add any windows and doors — the calculator takes them off the area, then walks you through battens, fixings, starter clips and corner trims, and works out the edging each wall needs. Skip any step for parts you already have, and leave out any wall you’re not cladding. Smooth Anthracite Grey comes in 2.5m and 3.6m boards, so choose the length that gives the fewest cuts across your longest wall.

Sleek, bold and timeless, our Smooth Anthracite Grey Cladding has been a popular choice with customers looking for a modern finish that can act as a blank canvas for a garden room or exterior project. The smooth surface and rich grey tone complement garden greenery and modern features alike, while the darker, dirt-concealing finish is a hit with parents and busy homeowners.
It blends cost with the added advantages composite provides, including improved moisture resistance and more consistent colour compared with traditional timber. Unlike our enhanced wood-grain or more textured finishes, the plain sanded surface has no deep grain for dirt to settle into, making it particularly easy to clean and touch up when needed. The result is a sleek, modern finish that works across a wide range of exterior projects while keeping ongoing cleaning and maintenance straightforward.
Like all our exterior composite cladding, some initial weathering and colour change should be expected as the boards are exposed to UV and the elements. From our experience and customer feedback, colour change can be up to 20%. These boards also pair particularly well with our composite fencing, with an exact colour match available in our Smooth Fence Panels if you’re looking to keep the same Anthracite Grey consistent throughout your garden design.

Expert Advice On Our Anthracite Grey Smooth Cladding
A Word from Our Expert, Allan Jeffrey BSc. Eng. (Hons), Composite Materials Specialist, Environmentalist, and CEO of Ultra Decking:
Our standard Anthracite Grey has been a customer favourite for nearly a decade. These composite cladding boards use a smooth, sanded finish with a distinctive dark grey colour and slight blue tint, giving you a sleek, contemporary surface that works particularly well on modern garden rooms and exterior projects.
One of the things I like about the smooth finish is that it acts almost like a blank canvas. It blends well with different garden features, bi-fold doors and both lighter and darker colours without adding another heavy texture to the project. We’ve seen it work particularly well alongside lighter Grey Composite Decking, where the contrast between the lighter deck and darker Anthracite Cladding helps break up the grey tones across the garden.
The sanded surface is also quite forgiving. Most minor scuffs and scratches can be carefully blended with a gentle rub from a soft wire brush, which is useful on an exterior that’s going to see everyday use.
One thing I always point out when choosing this smooth, sanded finish is the initial weathering period. You may see temporary water marks or tannin staining after rainfall, particularly during the first few months after installation. This is a natural part of the board’s initial weathering and can continue for around the first six months as the surface settles into its longer-term appearance.”
