Although, Merbau has the greatest stability rating, which describes the swelling or shrinkage of wooden boards, it is critical that you treat your distribution of Merbau with the utmost care. (If you are saving other Australian hardwoods or decking timbers, it’s even more important that you handle them with care as well). To take the uncertainty out of the best ways to correctly look after your Merbau from shipment to setup, we have created an useful list …
- When you get your shipment of Merbau Decking Timber, check to see if there are some lighter colored boards in the load and if so, you can leave these particular 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 don’t have an undercover area to save the Merbau shipment, ensure 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 wetness from the ground, as you stack them and save them. Likewise, cover the boards with plastic or tarp to further secure them from the weather. However, understand when making use of tarpaulins to cover Merbau, that the boards will sweat under the tarpaulins, if left kept in the sun, which will make the boards shrink and swell. This is another reason we advise that the boards always be kept in the shade, if there is no undercover readily available.
- Never ever 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 be careful around pools that have actually sandstone or bluestone tiles and rendered walls. Plus, the dust from cutting from Merbau will also 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 about 1 Day prior (where possible), which minimises the decking board taking in wetness and therefore making it more stable. If your deck is developed less than 250mm above ground level, it is absolutely essential to coat your boards before they are laid down.
