Please enter the actual square meterage you’re looking to cover. We take into account leaving a gap between the boards, which you can change here, to provide you with the correct amount of timber.
Cumaru is a heavily durable, tropical timber. The timber itself is a medium to dark brown with the occasional Reddish/purplish hue, there may also be some pieces with yellowish/greenish brown streaks. On touch, the timber has a waxy/oily feel to it.
As with the majority of tropical timbers, Cumaru decking, is exceptionally durable with a long lifespan. The wood is capable of withstanding all weathering and punishment without the need for treatment. It is also resistant to rot, mould and most insect infections (although some infestation is still a possibility).
We supply Cumaru decking in IWD7 which is smooth on all sides and rounded on the edges. This profile is fully reversable, so you get to see whichever side you prefer. The colour and pattern of the grain are two of the factors which may sway your decision. The section size of the boards is 21mm x 145mm and the corners are rounded to a 3mm radius.
Select and Better Grade Cumaru Timber
A common factor among tropical timbers in the small amount of knots in the wood and Cumaru is no different. The Select and Better grade we supply is kiln dried and highly stable, so there is very little moisture movement even without treatment.
Cumaru timber has an interlocked grain which makes it difficult to work with. So, buying it pre-machined ready to fit is a major advantage in order to save yourself precious time and effort.
Fixing and Treating
It is important to pre-drill any holes in the timber in order to avoid splitting. Also make sure that any screws or nails used are stainless steel, otherwise, the metal may react with the tannins in the timber causing blue staining.
When laying the deck you can leave a gap between each board (they don’t interlock like a T&G flooring). Usually the gap is 4mm-6mm, this ensures that items like chair legs don’t fall through.
You do not need to treat this timber in order to increase its lifespan and when laid correctly it could last in excess of 30 years. If you would like to preserve the colour and stop the sun from bleaching it you can treat the wood with a UV protector, however, you would need to retreat every so often.

More About Cumaru
Also known as Brazilian Teak, Cumaru is distributed across South America in the north and central areas of the continent. The tree is heavily cultivated across Mexico and in the West Indies, not just for its timber, but also the Tonka Beans it produces. Tonka Beans are a vanilla substitute for producing cocoa, they are also used to flavour tobacco.
The tree can grow anywhere from 24m to 36m high with a truck diameter of 0.5m – 0.75m.

What are your delivery costs?
We calculate our delivery costs based on how far away you are from us, to get more information on this please check out our shipping costs page HERE.
Our delivery lorries visit different parts of the country on different days, so once your order is ready we will work with you to arrange a delivery day for when one of our lorries is in your area. We will always arrange the delivery day in advance with you.
We deliver weekdays Monday to Friday between the hours of 8am to 5pm. Our delivery vehicles will have multiple jobs on them which can affect the delivery time to you, depending on factors such as traffic and how long it takes to offload the previous jobs. The driver will call you in advance with an estimated time of arrival to make sure you'll be there.
Aside from delivery locations that are priced on application, your delivery will be provided with means of offloading from the truck. This may be by HIAB (lorry with a crane arm), or by supplied manpower. The method will be determined by the haulage company we use based on your location and available options at the time. Please note, both offload options will drop your order to the side of the lorry, they won't be able to carry it around the back of a property, for example.
For areas that are priced on application, by default, we will quote for delivery on a flat-bed lorry that you'll need to arrange to offload yourself. We can quote for offloading on request, but to these areas it's usually prohibitively expensive, and cheaper for you to hire a forklift, or arrange to have enough people on-site to offload.
