Merbau is a stunning and durable timber that has become a popular choice for decking in Australian homes. Known for its rich, reddish-brown hues and ability to withstand harsh weather conditions, Merbau timber offers both aesthetic appeal and functionality. However, like all timber decks, it requires regular care and maintenance to retain its beauty and longevity. In this guide, we’ll walk you through everything you need to know about looking after your Merbau deck so that it can continue to enhance your outdoor space for years to come.
Why Merbau is a Popular Choice for Decking
Before diving into maintenance tips, it’s worth understanding why Merbau is so widely used for decking in Australia.
- Durability: Merbau is naturally resistant to termites, decay, and fungal attacks, making it an ideal choice for outdoor environments.
- Aesthetic Appeal: Its deep reddish-brown tones make it visually striking and ideal for blending with a variety of exterior styles.
- Weather Resistance: Merbau timber can withstand Australia’s extreme weather conditions, from intense heat to heavy rainfall.
- Low Maintenance: Compared to some other types of timber, Merbau requires less intensive care, though it still benefits from regular attention.

1. Regular Cleaning: The First Step to Deck Maintenance
Why Clean Your Merbau Deck?
Cleaning is the foundation of any decking maintenance routine. It helps remove dirt, leaves, grime, and mildew, preventing them from staining or damaging the timber.
How to Clean Your Merbau Deck
- Use a Soft-Bristle Broom: Sweep away debris like leaves and dust regularly to keep your deck looking neat.
- Wash with a Timber Deck Cleaner: Use a specialised timber cleaner that is suitable for Merbau. These cleaners are formulated to remove stains, algae, and mould without damaging the wood. Avoid using harsh chemicals or pressure washers, as these can strip the timber of its natural oils and finish.
- Use Warm Water and Mild Detergent: For lighter dirt, a solution of warm water and mild detergent can be effective. Apply the solution with a soft brush or mop, then rinse with clean water.
For environmentally responsible cleaning methods, consult the Environmental Protection Authority (EPA) Australia .
Frequency of Cleaning
- Light Cleaning: Once every few weeks to remove surface debris.
- Deep Cleaning: 2-3 times a year to remove grime, mildew, or mould build-up.
2. Sanding and Refinishing Your Merbau Deck
Why Sand and Refinish?
Over time, Merbau timber can start to look weathered or faded due to exposure to sunlight and the elements. Sanding and refinishing helps restore its original beauty and protects it from further wear and tear.
How to Sand and Refinish Your Merbau Deck
- Sanding: Use a fine-grit sander (around 120-150 grit) to gently sand the surface of your deck. Sanding helps smooth rough spots, removes dirt trapped in the grain, and prepares the surface for refinishing.
- Choose the Right Finish: After sanding, choose a high-quality decking oil or sealer specifically designed for Merbau. These products penetrate the timber and provide UV protection while maintaining the wood’s natural colour. For a more natural finish, opt for a clear sealer, or for a darker tone, choose an oil with a tinted stain.
- Application: Apply the finish using a clean, soft cloth or brush. Work in small sections to ensure even coverage. Always follow the manufacturer’s instructions on application times and re-coating schedules.
When to Sand and Refinish
- Every 12-18 months: Depending on the level of exposure to sun, foot traffic, and weather, refinishing every year or two is ideal.
- Signs Your Deck Needs Re-finishing: If you notice the colour fading, a significant build-up of dirt, or water no longer beading on the surface, it’s time to refresh the finish.
3. Protecting Your Deck from the Elements
Why Protection Matters
The Australian sun and unpredictable weather can quickly damage your Merbau deck if left unprotected. Over time, exposure to UV rays and moisture can cause timber to crack, warp, and lose its vibrant colour.
How to Protect Your Merbau Deck
- Apply UV-Resistant Oil: Use an oil or finish with built-in UV protection to prevent sun damage and fading. This will keep your deck looking new and vibrant for longer.
- Install Decking Shields or Awnings: For added protection, consider installing a shade cover or awning over your deck to shield it from excessive sun or rain exposure.
- Move Heavy Items: Avoid dragging heavy furniture or objects across your Merbau deck, as this can cause scratches or dents in the timber.
Tips for Extreme Weather Conditions
- In Wet Conditions: Regularly check for pooling water or signs of moisture trapped in the timber. Moisture can cause mould and mildew growth, so make sure your deck is well-ventilated to dry out.
- In Hot Conditions: In the summer, the heat can cause Merbau timber to expand or contract. Keep the deck well-oiled to help it maintain its flexibility and resist cracking.
4. Repairing Damaged Merbau Decking
Why Repairing Is Important
Despite its durability, Merbau can still suffer from the occasional scratch, dent, or split due to heavy use or harsh weather. Taking quick action to repair any damage will help prevent further issues and keep your deck in top shape.
Common Decking Repairs
- Fixing Small Cracks: For minor splits or cracks, use a timber filler that’s designed for outdoor use. Apply the filler according to the product instructions, sand smooth, and then refinish the area.
- Replacing Damaged Boards: If a board is beyond repair, replace it with a new Merbau plank. Ensure the new board is treated with the same oil or finish as the rest of the deck.
- Screws or Nails: Tighten any loose screws or nails to prevent further damage. Always use corrosion-resistant fasteners suitable for outdoor use.
5. Long-Term Care for Your Merbau Deck
Protect Your Investment
While regular cleaning and refinishing can extend the life of your Merbau deck, proper long-term care ensures that your deck remains a valuable feature in your home for years to come.
- Routine Inspections: Conduct routine inspections of your deck to check for signs of wear, water damage, or pest activity. Catching issues early can prevent more expensive repairs down the track.
- Keep It Clear: Always keep the deck clear of debris, especially leaves and other organic matter that can trap moisture and encourage fungal growth.
