Accoya Decking

Accoya is a modified timber a substitute for tropical hardwoods

Modified by means of Acetylation. This Process renders the timber more durable and more stable than almost all other timbers. The timber is sourced from NZ but is modified in Holland.

The product is FSC certified.

The Accoya is not as hard as Kwila or Vitex, and is more brittle, but does not bleed, and is stable enough to use as a 190 x 20 board.


Although not very common in New Zealand, coating your deck will extend its life. We recommend a minimum of one coat of a suitable exterior timber decking coating or oil be applied to all four sides plus cut ends of the decking prior to installation. Some species can be factory coated prior to delivery.



Annually cleaning your deck will help prolong its life, a light detergent that contains an anti-fungal agent is best. 
Avoid using high-pressure water blasters or harsh chemicals.


Any coating or oil applied may require subsequent recoating. Refer to coating manufacturers maintenance schedule.
Winter: Removing any items that will trap water underneath them (furniture, pot plants, etc.) for the duration of winter will extend the life of your deck and help keep it looking great.
