Although, Merbau has the greatest stability rating, which describes the swelling or shrinkage of timber boards, it is vital that you treat your distribution of Merbau with the utmost care. (If you are storing other Australian hardwoods or decking timbers, it’s even more vital that you manage them with care as well). To take the guesswork out of how to correctly look after your Merbau from shipment to installation, we have actually developed an useful checklist …
- When you get your shipment of Merbau Decking boards, check to see if there are some lighter colored boards in the load and if so, you can leave these certain boards out in the sun. The tannins will come out due to sun exposure and they will darken.
- Store Merbau boards flat and even, so that they remain straight, and keep them undercover and out of the sun.
- If you do not have an undercover area to save the Merbau delivery, make sure that you put some battens down to raise the boards up and off any surface area, so that the boards aren’t soaking up any moisture from the ground, as you stack them and save them. Likewise, cover the boards with plastic or tarpaulin to further secure them from the elements. However, know when utilizing tarps to cover Merbau, that the boards will sweat under the tarps, if left kept in the sun, which will make the boards reduce and swell. This is another reason we advise that the boards always be stored in the shade, if there is no undercover available.
- Never leave Merbau decking boards on concrete, whether they are off-cuts or full boards due to the fact that if it rains, the Merbau will bleed and leave red marks on the concrete. You likewise have to beware around swimming pools that have actually sandstone or bluestone tiles and rendered walls. Plus, the dust from cutting from Merbau will likewise stain, if moistened. Take special note that the red stain is notoriously hard to eliminate!
- Before installation, it is suggested that you pre-coat the Merbau boards approximately 1 Day prior (where possible), which minimises the decking board taking in wetness and therefore making it more steady. If your deck is developed less than 250mm above ground level, it is definitely necessary to coat your boards before they are laid down.
