Preparation: The Secret to Long-Lasting Decking Protection

The intense Queensland sun and coastal humidity will break down timber oil within 12 to 18 months if prep is rushed. Never apply fresh oil over old, peeling coatings.

Start by checking for loose deck screws or nails and driving them flush. Next, sand the entire deck with an orbital sander or hired floor sander using 80-grit paper. This opens the grain, allowing the timber oil to penetrate deeply rather than sit on the surface.

The Application: Oiling Like a Pro

Once sanded, apply a specialized timber wash to remove sanding dust and natural tannins. Let it dry completely for 24-48 hours.

Using a lambswool applicator pad, work along the length of 2 to 3 boards at a time. Apply a thin, even coat of premium natural timber oil, avoiding pools or drips. Let the first coat cure for 24 hours before applying a second coat.

Frequently Asked Questions

How long should I wait before walking on the oiled deck?

Wait at least 24 hours for light foot traffic and 3 to 5 days before dragging heavy furniture back onto the deck.

What timber oil is best for North-facing decks?

For maximum UV resistance in QLD, choose a premium tinted oil (like Cabot's Aquadeck or Feast Watson) which filters out the sun's rays better than clear oils.
