Decking Maintenance Season

Now that winter is behind us, it’s the perfect time to revitalise your outdoor space. The beauty of Preschem’s Australian Made range—including Aussie Clear, Walnut Timber Finish, and Exterior Pine Clear—is that they are incredibly simple to apply, and the results are simply stunning.

Because our finishes are non-film-forming, maintenance is straightforward; however, achieving a professional, long-lasting look starts with the right preparation. Follow this guide to ensure your timber remains protected and beautiful all year round.

1. Product Selection: Find Your Perfect Match

Preschem offers four premium options for protecting your exterior timber. Choosing the right one depends on the look you want to achieve:
  • Aussie Clear: The original choice for mid-to-dark hardwoods (like Merbau or Spotted Gum). It enhances rich honey-brown tones with a sophisticated matte finish.
  • Aussie Clear Light: Specifically designed for blonde-to-mid hardwoods (like Blackbutt or Silvertop Ash). It provides a natural “wet straw” look without over-darkening the timber.
  • Walnut Timber Finish: Our premium choice for a rich, dark brown designer aesthetic. Perfect for transforming blonde timbers or deepening the character of any hardwood with a consistent walnut tone.
  • Exterior Pine Clear: Formulated strictly for Treated Radiata Pine. This contains no pigment and maintains the natural pine colour with a nourished, oiled appearance.
 
 

2. Essential Deck Preparation

Preschem has written about this before in other news posts, but lets recap. Preparation is the secret to a finish that doesn’t peel. Weathering and dirt buildup prevent new oil from penetrating the wood fibres.

The Water Test: Splash some water on your deck that’s exposed. If the wood looks dark, grey and lifeless, or if the water doesn’t bead, it’s time to clean. Preschem recommends Grey Deck Cleaner to open the grain and remove contaminants:

    1. Safety First: Wear appropriate PPE and read the label instructions.
    2. Mix: Dissolve 1kg of Grey Deck Cleaner in 10L of hot water.
    3. Scrub: Use a stiff deck brush to scrub the solution into the timber.
    4. Rinse: Wash off thoroughly with a hose or pressure cleaner.
    5. Dry: Allow 12-24 hours for the deck to dry completely before oiling.

3. Application for a Stunning Result

Once dry, apply your chosen Preschem timber finish:
  • Stir well to ensure even pigment distribution.
  • Cut in edges near walls and posts first.
  • Apply using a lambswool applicator for a smooth, even coat.
  • Wipe off any excess oil after 1–2 hours to prevent over-oiling.
  • Clean up applicator and brushes with mineral turps.
