Merbau Colour & Grain

Consisting of a pale to dark reddish brown often showing a tinge of orange. The timber colour is exceptional when a clear oil or stain is applied to allow its natural beauty to come out.

Depending on the stocks available, the grain can be variable and interlocked which produces a radial surface, or it can be mostly straight which allows for it’s reliability when laid.

The texture is evenly coarse and sharp tools should be used to achieve a smooth, even finish.

Merbau is certainly a favourite of Decking 4 Perth. It takes extremely well to all stains, oils and even paint. The one thing that needs astute attention when using this timber is the gum bleed.

This timber will bleed once laid for a few weeks until dried thoroughly. Care must be taken to avoid drips on paving, concrete or any hard surface as the bleeding is very difficult to remove.

Also avoid installing during rain periods as it can splash up against walls and rendered surfaces.

It is relatively easy to work with when using sharp tools. Merbau tends to split around end boards and it is highly recommended to pre-drill and countersink all holes prior to screwing.
