Why Use Decking Oil on Timber Decks?

Maintaining your deck with Exterior Decking Oil is one of the best ways to prolong its life. Sun, storms, dirt, and pollution can all damage outdoor timbers. Left untreated, decks dry out, leading to cracks, warping, and rot—problems that not only look bad but can be costly to repair or even require a full deck replacement.

To avoid this, apply decking oil every 6-12 months. Regular oiling protects against the elements and prevents drying, splintering, and cracking.

How to Apply Exterior Decking Oil

Treating your deck is a simple weekend project that just requires a few key steps: clear the area, clean the timber, sand rough spots, and apply a thin coat of decking oil, allowing time to dry between coats. For best results, choose a cool, dry period in Spring or Autumn and avoid rainy days.

How Much Exterior Decking Oil Do I Need?

The amount of oil you’ll need depends on the size of your deck and the products you’re using. For WOCA’s water-based exterior decking oil you need:

  • 1L per 8-10 square metres (first coat)
  • 1L per 10-15 square metres (second coat)

For example, the average deck is about 30 square metres. You would need 3.75L for the first coat, and 2-3L for the second coat.

It’s a good idea to order more oil than you think you’ll need. Each type of timber reacts differently to being oiled, with some species soaking up more treatment than others.

That’s especially true if it has been a long time since the deck was last oiled. Having extra product means you won’t run out part way through the project, ensuring you get a nice, even finish.

Can Exterior Decking Oil Be Used on Wooden Furniture?

Yes! Exterior decking oil is ideal for treating a huge range of outdoor surfaces. Because timber is a living material, it tends to fade and dry out over time. Regularly recoating the surface with a natural oil replenishes the moisture, prevents fungus and protects against the sun.

Natural decking oil can be used on treated and untreated outdoor timbers, such as:

  • Outdoor furniture
  • Wooden handrails and trims
  • Privacy and decorative screens
  • Fences and lattices
  • Timber cladding
  • Doors and shutters

The process for treating outdoor timbers is the same as it is for decking. Explore our Timber Floor Cleaner products.
