Merbau care & maintenance

Deck maintenance is essential for timber and composite decking of all types. Merbau is the perfect decking choice if your deck is in a weather exposed area because of its high levels of durability. Merbau is an extremely stable timber option, so it has low tendency to twist and warp if it is installed correctly.

To keep your Merbau decking in top condition, you’ll need to control and minimise the release of tannins when it gets wet. This will not continue indefinitely and there are ways to limit it, such as staining and coating your decking.
