The Importance of Exterior Oils to Protect Outdoor Timber

Timber is a popular choice for outdoor structures and furniture due to its natural beauty, durability, and versatility. However, when exposed to the elements, even the most resilient timber can suffer from weathering, moisture damage, and UV degradation. To maintain the aesthetic appeal and structural integrity of your outdoor timber, it’s important to select the right exterior oils.

Why Protect Outdoor Timber?


Outdoor timber is constantly exposed to varying weather conditions, including sunlight, rain, snow, and humidity. These elements can cause timber to expand, contract, crack, and warp over time. Without proper protection, timber can quickly lose its strength and visual appeal.

Moisture damage

One of the most significant threats to outdoor timber is moisture. Wood is a porous material, and when it absorbs water, it can lead to swelling, mould growth, and eventually rot. This not only affects the timber's appearance but also its structural integrity, making it unsafe for use.

UV Degradation

Ultraviolet (UV) rays from the sun can break down the lignin in wood, causing it to fade, turn grey, and become brittle. This process, known as photodegradation, weakens the timber and makes it more susceptible to further damage.


How Exterior Oils Protect Timber

How Exterior Oils Protect Timber

Exterior oils penetrate into the timber, creating a protective barrier that repels water and prevents moisture from seeping in. This barrier helps reduce the risk of swelling, mould growth, and rot, extending the life of your outdoor timber.

UV Protection

Many exterior oils contain UV inhibitors that shield the timber from the harmful effects of the sun's rays. These inhibitors slow down the photodegradation process, helping the wood maintain its natural colour and strength for longer periods.

Enhance Natural Beauty

Exterior oils enhance the natural beauty of timber by bringing out the wood's grain and colour. They provide a rich, lustrous finish that not only looks beautiful but also adds an extra layer of protection against the elements.

Easy Maintenance

One of the advantages of using exterior oils is their ease of maintenance. Unlike paint or varnish, which can chip and peel over time, exterior oils penetrate the wood and do not form a surface film. This makes it easy to reapply oil as needed, without the need for extensive sanding or stripping.


Choosing the Right Exterior Oil

When selecting an exterior oil for your outdoor timber, consider the specific type of wood and the environmental conditions it will be exposed to. Whittle Waxes offers a range of popular exterior oils:

Whittle Waxes Bangkirai oil.

Whittle Waxes Bangkirai Oil is a trusted, tried-and-tested solution for maintaining and enhancing the beauty of your exterior timber. Its powerful formulation ensures long-term protection against the elements while being safe and eco-friendly. Perfect for decks, garden furniture, and other outdoor structures, this oil brings out the best in your timber, extending its life and keeping it looking stunning year-round. For those seeking a blend of durability, beauty, and sustainable production, Bangkirai Oil is the ideal choice.

  • Designed to extend the life of exterior timbers such as Jarrah, Meranti, and Merbau.
  • Bangkirai Oil is quite heavily pigmented which can therefore mask the grain of some timbers.
  • Bangkirai Oil does not contain active ingredients that inhibit the growth of mould and mildew, making it Beehive Safe.
  • Safe for use on children's toys
  • Suitable for outdoor horizontal and vertical surfaces

Whittle Waxes Sun Protection Oil

Whittle Waxes Sun Protection Oil is a reliable shield designed to combat the damaging effects of UV rays while enhancing the natural beauty of your timber. One of the standout features of this product is its UV-resistant clear finish. While it protects your timber from harmful UV rays, it also allows the natural beauty of the timber to shine through, delivering a clearer timber look, rather than a varnish look. Whittle Waxes Sun Protection Oil is highly water-resistant and contains an active ingredient that protects against mould, algae, and fungal infection, ensuring your timber remains healthy and beautiful.

  • Suitable for outdoor vertical surfaces such as: Wooden cladding, Carports, Doors and windows, Window shutters, Fences, Pergolas, Outdoor furniture and Cubby houses.
  • Not suitable for horizontal timbers as they tend to wear sooner due to foot traffic and other factors, and hence, may not retain the oil's protective qualities as effectively. We recommend Whittle Waxes Bangkirai Exterior Oil or Cutek Wood Coatings for exterior horizontal surfaces such as outdoor decks.
  • Not suitable for coating beehives as it contains active ingredients that inhibit the growth of mould and mildew. We recommend Whittle Waxes Bangkirai Exterior Oil or Whittle Waxes Teak Oil for the exterior coating of beehives instead, and Whittle Waxes Hardwax Oil for coating the interiors of beehives.

Whittle Waxes Teak Oil

Whether you're maintaining a yacht deck, pool deck, or ensuring the longevity of your outdoor furniture, Whittle Waxes Teak Oil provides excellent protection against moisture and UV rays. Whittle Waxes Teak Oil is a specially formulated, solvent-free emulsion that delivers a low sheen, abrasion-resistant finish and protects the timber surface against algae and moss by drying quickly.

  • Not suitable for high tannin content timbers
  • Satin-matte finish
  • Teak oil is ideal for outdoor furniture and marine applications.
  • Safe for use on children's toys, safe for the environment, safe for bees.

CUTEK® Extreme CD50

CUTEK® Extreme CD50 is a high-performance, oil-based wood stabiliser that highlights the natural grain and beauty of wood, while providing robust and long-lasting protection. Working from the inside out to control moisture, and minimise warping, cupping, and splitting, CUTEK® Extreme CD50 improves the service life of your timber. Applied as a clear oil, CUTEK® Extreme CD50 will allow wood to naturally silver over time. Mixing in one of the many CUTEK® Colourtones will help to enhance and maintain the freshly oiled natural look of your wood or alter your wood colour to meet your design requirements.

  • A highly effective, non-drying oil that is suitable for exterior horizontal and vertical applications such as decks, pergolas, carports, fences, etc.
  • As CUTEK® is a non-drying oil, the oil can float to the surface if water is allowed to pool over the timber. Reapplication of the oil will be required to continue to protect the timber.
  • Not suitable for use on food preparation surfaces, children's toys, beehives, kennels, or stables.

Protecting your outdoor timber with exterior oils is essential to preserving its beauty and durability. By providing a moisture barrier, UV protection, and enhancing the wood's natural appearance, exterior oils help extend the life of your outdoor timber structures and furniture. With the right oil and proper application, you can enjoy the timeless elegance and strength of timber for years to come.

The Whittle Waxes Story

Most companies go from A to Z. We went from Z (Zimbabwe) to A (Australia). What an exciting journey it has been - and it's not over yet!

Although Whittle Waxes officially launched in Australia in 2004, our journey (and love affair) with timber started a long time before that. Company founder, Giles Whittle-Herbert, grew up on a farm in Zimbabwe, where he inherited a passion for working with wood that goes back generations. For many years he ran a successful carpentry business in Zimbabwe.

On arrival in Australia in 2004, Giles noticed a big gap in the market for natural and safe hardwax oils. He already had an excellent working relationship with an overseas supplier, so all he needed to do was make the Australian market aware of the many benefits of hardwax oils.

20 years later, Whittle Waxes is proud to be leading the way in the supply of natural, high quality finishes in Australian, with satisfied customers across the board, including home renovators, professional polishers, flooring suppliers, timber companies, architects, and designers.

Our Evolution Hardwax Oil continues to exceed expectations and is now a firm favourite all across the country, particularly with those who appreciate a quality finish that is safe, durable and environmentally friendly. Whittle Waxes has introduced a number of other quality products, including colour stains, exterior oils, Wax Polish and Floor Care for easy floor maintenance.

At Whittle Waxes, we genuinely love to interact with our clients so if you have any questions, please do not hesitate to get in touch. Thanks for all your support!
