Timber Deck Care in Australia’s Climate

A timber deck is a true Aussie lifestyle feature—perfect for BBQs, outdoor dining, and relaxing outdoors. But with Australia’s harsh sun, heavy rain, and humidity, timber decks need proper care to stay beautiful and strong.

Here’s how to maintain and protect your timber deck so it lasts for many years.

1. Clean Your Deck Regularly

Dirt, leaves, and moisture can build up and cause mould or mildew.

• Sweep weekly to remove debris.
• Wash the surface with a deck cleaner every few months.
• Use a pressure washer on a low setting if needed, but avoid damaging the wood fibres.

2. Protect Against Sun Damage

Australia’s strong UV rays can cause timber to fade and dry out.

• Apply a UV-protective deck oil or stain to keep colour and prevent cracking.
• Products like Sikkens Cetol® Deck are designed for long-lasting UV resistance in Australian conditions.

3. Guard Against Moisture & Mould

Rain and humidity can make timber swell, rot, or develop mould.

• Ensure your deck has good drainage and airflow underneath.
• Reapply a water-repellent finish every 12–18 months.
• Haymes Woodcare range offers durable options that resist moisture and keep your deck looking fresh.

4. Sand & Reseal When Needed

If your deck looks grey, rough, or patchy, it may be time for refinishing.

• Sand back the timber to remove weathered layers.
• Reapply a stain, oil, or paint suitable for exterior timber.
• This restores natural beauty and strengthens protection.

5. Seasonal Maintenance Tips

• Spring: Best time to deep clean and reseal before summer.
• Summer: Sweep regularly and avoid heavy cleaning in extreme heat.
• Autumn: Clear fallen leaves to prevent moisture damage.
• Winter: Watch for mould growth—clean with a deck wash if needed.
