Frequently Asked Questions

Its appearance is a highly convincing timber decking board, with realistic wood grain, tone and texture. This look is achieved through a process of hand-moulding genuine timber boards, which are then hand-tinted, making each piece of Millboard unique.
Millboard composite decking is made from a revolutionary Polyurethane resin, reinforced with mineral fibres plus a unique Lastane® coating. Polyurethane is a type of elastomer — a polymer about halfway between a plastic and a rubber. It maintains the rigidity and longevity of plastic, with the suppleness of rubber. This means Millboard feels much more natural underfoot, while still offering incredible durability.
Millboard is extremely versatile and can be used in practically every outdoor space. Create decks, balconies, roof gardens, boardwalks, bridges, pontoons, seating, steps, screening, planters and more.
To recreate the aesthetic of natural colour variation, Millboard intentionally adds secondary toning colours. There may be variance within the same board or from board to board in colour tone. Whilst every care is taken to ensure consistency, some colour variation from batch to batch may occur. To avoid this, we recommend that you order all you need in one delivery. If you do have different batches it is best to mix them to blend the colours.
Millboard has a very high resistance to fading because it contains no wood fibres which typically fade and leach tannins. Millboard has been UV stability tested to BS EN ISO 4892-2: 2006 with a result of 2% LRV (shift over 5000hrs) — rated Exceptional. As with all products constantly exposed to UV light and all weathers, especially in Australia's extreme conditions, colours will tone slightly over time.
There will always be a slight variance in the board's dimensions due to the fact that we mould from natural oak and due to the pressure of the moulding process. Manufacturing tolerances are: Width: ± 3mm. Length: ± 5mm. Thickness: ± 2mm. The dimensions of the Weathered Oak style may vary more between moulds. Dimensional variation is also possible with our Envello® cladding boards and the same manufacturing tolerances apply.
Millboard is manufactured with non-porous material, meaning it doesn't absorb moisture, making it highly stain resistant. A simple brush down and rinse with soapy water is all that's needed. There's no need for pressure washing as there are no pores for dirt to become ingrained. Unlike traditional timber or common wood/plastic composites, Millboard doesn't contain any timber, flour or husk fibres, so it will not host algae or mould growth.
Millboard is perfect for use in marine environments or by the beach. Salt water will not corrode Millboard products, making it an ideal choice for coastal homes and commercial projects.
