How to maintain the colour of Merbau decking?
Hello, I’ve recently moved to a new place. There is a smallish and newish deck made of merbau. When it rains I can see the red colour of the wood which I would like to preserve, rather than let it naturally turn to grey.
what should I do?
with thanks B

Re: How to maintain the colour of merbau decking
Welcome to the Bunnings Workshop community @A1821801. It's a pleasure to have you join us, and many thanks for your question about preserving a deck.
That sounds like a brand-new deck that hasn't finished leeching tannins. @Nailbag has provided a fantastic guide to follow, but it sounds like you also need to let the deck leech tannins. Before Merbau can be coated, the tannins need to be stripped from the timber, and this can either be done through natural weathering over several weeks, or you can use a chemical product to accelerate this process.
So, you'll scrub the deck down with Cabots New Timber Prep to remove the tannins, then use the Cabots Deck Clean and then Cabots Merbau Decking Oil.
Remember your PPE, including safety glasses, chemical-resistant gloves, a long-sleeved shirt and trousers and enclosed footwear.
Please let me know if you have any questions.
