Blackbutt Decking Sydney: Durable Elegance for Your Outdoor Living

Are you looking for a one-of-a-kind hardwood deck that holds its shape and style year after year?

The colour of each blackbutt deck board varies (thanks to the beauty of genuine hardwood), giving you an appealing and practical addition to your home.

In terms of appearance, blackbutt decking typically features a warm golden-brown color with a straight grain. It provides a clean, contemporary look that complements various architectural styles.

With a light hue, blackbutt can create the illusion of space in smaller areas, or provide unmatched strength and durability when building a large outdoor deck. No matter the design of your home, a deck feels like it’s always been part of the landscape, offering a timeless space to unwind or entertain today, tomorrow and for generations to come.

The Blackbutt Deck Difference

Blackbutt is practically designed by Mother Nature to deliver stunning deck boards that stand the test of time.

Offering advanced strength and durability, this hardwood timber can withstand hot Sydney summers and windy winters without bending, breaking or moving an inch. Ideal for external and structural use, it is used across decks, cladding, joinery and even internal flooring – allowing you to create hybrid living spaces that mix the inside and the outside for the ultimate lifestyle.

As an added bonus, the density of blackbutt (at 900kg/cubic metre) offers protection against some of the most common blights affecting homes – bushfires and termites.

And whether you live near a bushfire prone suburb or not, blackbutt’s fire-resistant qualities mean floating embers, or an overly packed fire pit, don’t pose a threat to your deck.

Get Ready for an Eye-Catching Backyard

The design of a deck and the look of the deck boards chosen can help in the decision to  install a new deck (or upgrade an existing one).

Blackbutt decking is one of natures gifts.  Its even texture includes a typically straight grain, lending itself to both decks and joinery in equal measure. As a native Australian hardwood tree, these deck boards are a striking combination of golden yellow through to pale brown, with light pinkish tones even popping up from time to time.

 Blackbutt takes well to staining. This means you can colour your deck’s boards in a range of stylish finishes to suit your home decor or outdoor space.

What colour is Blackbutt decking?

Blackbutt decking is widely recognized as the premium choice for blonde decking. Its heartwood exhibits a spectrum of colors, from golden yellow to pale brown, sometimes tinged with a hint of pink. The sapwood, on the other hand, is much lighter in color and can be difficult to distinguish from the heartwood.

How long does a Blackbutt deck take to install?

When it comes to a hardwood timber deck, it’s not the timber that impacts your construction timeline. Although certain hardwood timbers are easier to work with than others (relating to their ability to be sawed or machine cut), the deck construction process is typically broken into three distinct periods:

Phase one is the most time-consuming, with council applications and decking design taking time and energy. But once your deck has the seal of approval from your local council, construction can begin.

At UrbanArch Building, we strive to complete each job to the highest standards with minimal disruption to your life and routine. With the highest quality products, materials and specialists, we’re proud to let our results speak for us and endeavour to deliver an end product that meets and exceeds your vision.

How is a Blackbutt deck oiled?

Oiling a blackbutt deck is a good way to enhance its appearance, protect the wood, and extend its lifespan. Here’s a step-by-step guide on how to oil a blackbutt deck:

  1. Prepare the Deck: Start by ensuring the deck is clean and free of debris or dirt. Sweep or brush the surface thoroughly to remove any loose particles. Use a product like oxalic acid or Cutek Proclean to clean the deck. This will remove stains and brighten up the deck boards. Follow the manufacturer’s instructions and use a garden hose to give the deck a final wash down. Allow the boards to dry for several days to ensure that the boards are moisture free and ready for oiling.

  2. Choose the Oil: Select a high-quality penetrating deck oil designed explicitly for hardwoods like Blackbutt. Look for an oil that provides UV protection and is suitable for outdoor use. We recommend the Cutek range of oils and colour tones.

  3. Test the Oil: Before applying the oil to the entire deck, it’s a good idea to test it on a small inconspicuous area or a leftover piece of blackbutt wood to ensure you’re happy with the colour and finish.

  4. Apply the Oil: Using a paintbrush, roller, or applicator pad, apply the deck oil evenly to the blackbutt deck boards. Work in small sections, following the direction of the wood grain. Ensure the oil is used uniformly and avoid leaving puddles or excess oil on the surface.

  5. Allow Penetration: Allow the oil to penetrate the wood according to the manufacturer’s instructions. This typically ranges from 10 minutes to 30 minutes. It’s essential to let the oil soak in to achieve proper protection and a consistent finish.

  6. Wipe Off Excess: After the recommended penetration time, use a clean cloth or mop to remove any excess oil the wood has not absorbed. This step helps to prevent a sticky or tacky surface.

  7. Drying Time: Allow the oiled blackbutt deck to dry completely. The drying time can vary depending on weather conditions. It can take up to 24 hours to dry. Avoid walking on the deck or placing furniture on it until fully dry.

  8. We recommend two or three coats of oil for maximum protection based on the location of your deck. The more your deck is subject to the effects of the sun, the more it will benefit from an additional coat of oil.

  9. Make sure the first coat is fully dry before applying the second coat.

  10. Regular Maintenance: To maintain the oiled blackbutt deck’s appearance and protection, reapply the oil periodically as the oil manufacturer recommends or when the wood begins to look dry or weathered.

Remember to follow the oil manufacturer’s specific instructions for the best results. It’s also a good idea to consult with a professional or refer to the product guidelines for additional recommendations based on your specific blackbutt deck and environmental conditions.

Frequently Asked Questions About Sydney Blackbutt Decking

Is Blackbutt good for decking?

When used for decking, blackbutt timber can provide a beautiful, natural look to outdoor spaces. It can complement various architectural styles and provide a versatile base for outdoor living spaces. It has a warm, honey-brown colour with occasional subtle pinkish tones.  It can be easily combined with other materials, such as stainless steel or glass, to create a customised and contemporary deck design.

Blackbutt timber is known for its stability, an important factor for decking. It has a relatively low shrinkage rate, meaning it is less likely to warp or twist when exposed to changes in moisture and temperature. It is also a good choice for decking due to its durability, strength, and aesthetic qualities.

Blackbutt timber is generally easy to work with, making it a popular choice for professional builders and DIY enthusiasts. It can be cut, shaped, and installed relatively easily, which can help streamline the decking installation process.

Adding its natural resistance to decay, termites and insect attacks, you have the perfect timber for a beautiful, long-lasting deck.

Remember, while blackbutt timber offers many advantages for decking, assessing your specific needs, budget, and local environmental factors is essential before making a final decision. Additionally, following proper installation techniques and adhering to local building codes and regulations is crucial for ensuring a safe and structurally sound deck.

If you have any specific concerns or requirements for your decking project, consult a professional builder, architect, or timber specialist who can provide detailed information and recommendations.

Does Blackbutt decking get hot?

During our intense summers, materials can become quite hot. Decking materials that are darker in colour, such as Merbau and Jarrah, tend to absorb more heat than lighter ones because they absorb more  sunlight. This can cause the surface of the decking to become quite hot, particularly when exposed to direct sunlight.

Lighter-coloured woods such as or blackbutt, tend to reflect more sunlight and heat, making them generally cooler to the touch. However, it’s important to note that all decking materials can become warm under the sun, regardless of colour.

When selecting a decking material in Sydney or any other location with a warm climate, it’s important to consider factors such as sun exposure, shade coverage, and the overall comfort of the deck. In areas where intense sunlight is a concern, consider including shading options, such as umbrellas or pergolas to reduce direct sun exposure and reduce heat retention on the deck surface.

Additionally, regular deck maintenance and cleaning, regardless of colour, can help prevent the buildup of heat-trapping debris and improve its comfort.

Ultimately, it’s a good idea to consider your specific climate, deck location, aesthetic preferences, and the intended use of the deck when choosing between darker or lighter-coloured decking materials. Consulting with local decking professionals or suppliers can provide further insights into your situation’s best options.

Where does this type of hardwood grow?

It is found in coastal NSW and southern QLD. A taller eucalyptus variety, the trees can grow up to 50 metres high.

Is Blackbutt decking termite-resistant?

Yes. It is a dense hardwood (900kg/cubic metre) with a density that makes it tough for the most determined of termites to make their home in your deck.

Blackbutt decking is generally considered to have a good natural resistance to termites but is not entirely termite-proof. Blackbutt is a dense hardwood, and its natural characteristics make it less attractive to termites than softer wood species. However, it’s important to note that no wood is entirely immune to termite infestation.

While blackbutt may offer some inherent resistance to termites, it is still recommended to take preventative measures to protect your decking from termite damage. Here are a few steps you can consider:

  • Regular Inspections: Regularly inspect your blackbutt decking to detect any signs of termite activity, such as small holes, mud tubes, or wood damage. Early detection can help address the issue before it becomes extensive.

  • Proper Installation: Ensure that your blackbutt decking is properly installed, with appropriate ventilation and clearance from the ground. This can help minimise the risk of termites accessing the wood.

  • Regular Maintenance: Regularly clean and maintain your blackbutt decking, including keeping the area surrounding the deck free from debris and vegetation. This reduces potential hiding places and moisture accumulation, which can attract termites.

  • Professional Advice: Consider consulting with a pest control expert or a professional in your area specialising in termite prevention. They can provide specific recommendations and guidance tailored to your location and circumstances.

    Remember that while blackbutt decking may have a natural resistance to termites, it is always important to remain vigilant and take preventive measures to protect your investment and ensure the longevity of your deck.

Do I need council approval to build a deck?

Council regulations vary, though certain heights, sizes, and materials may need authorisation before construction begins. Your deck installation team will walk you through these requirements.

How to clean a Blackbutt Hardwood deck?

Blackbutt decking is easy to clean, with regular maintenance the key to longevity. Outside of regular oiling and staining,  you can clean your board with a mop and pH neutral cleaning agent. Avoid steam mops, abrasive brushes or steel wool.

To keep your blackbutt deck looking pristine, it’s crucial to clean it regularly. Here are some steps you can take to clean your blackbutt deck effectively:

  • Remove Debris: Start by getting rid of any debris, such as dirt, leaves, or twigs, from the surface of your deck. Use a broom, leaf blower, or soft-bristled brush to thoroughly sweep the deck.

  • Prepare a Cleaning Solution: Create a mild cleaning solution by mixing warm water with a gentle detergent. Avoid using harsh chemicals or bleach as they can damage the wood. Instead, use a mild dish soap or a specialized deck cleaner recommended for hardwood.

  • Apply the Cleaning Solution: Use a mop, soft brush, or deck cleaner applicator to apply the cleaning solution to your blackbutt deck. Work in small sections to ensure even coverage. Follow the manufacturer’s instructions and let the cleaning solution sit on the deck for a few minutes.

  • Scrub the Surface: Gently scrub the deck’s surface in the direction of the wood grain using a soft-bristled brush or a deck scrub brush. This will help remove stains, dirt, and grime. Be careful not to apply too much pressure or scrub too aggressively, as it can damage the wood fibers.

  • Rinse Thoroughly: After scrubbing the deck, rinse it thoroughly with clean water. Use a garden hose or a pressure washer on a low setting to rinse away the cleaning solution and loosened debris. Make sure to remove all soap residue.

  • Allow to Dry: After rinsing, allow your blackbutt deck to air dry completely before walking on it or placing furniture on it. Depending on the weather, this may take a few hours or longer.

By repeating this cleaning process once or twice a year, you can help maintain the beauty and longevity of your blackbutt deck. However, the cleaning frequency may vary depending on factors such as climate, level of use, and exposure to the elements. Always follow the manufacturer’s recommendations and consult with a professional if needed.

Blackbutt Decking: Pros and Cons

It is known for its strength and durability, leaving you a deck that handles family gatherings, Christmases and events year after year no matter how many guests you entertain. Blackbutt is a really beautiful timber, and luckily for us, its pro’s more than outweigh its con’s.


  • Durability: Blackbutt is a durable hardwood known for its strength and resilience, making it suitable for outdoor applications like decking. It can withstand heavy foot traffic and resist rot, decay, and insect damage.
  • As a naturally fire-resistant hardwood timber, blackbutt is ideal for decking in bushfire prone areas thanks to its natural ability to protect against fire damage.
  • Natural Beauty: Blackbutt has an attractive appearance with a warm honey or pale brown color and a straight grain pattern. It can add a touch of elegance and natural beauty to your outdoor space.
  • Versatility: Blackbutt decking can be stained, oiled, or left to weather naturally, giving you various options to customize its appearance to match your desired aesthetic.
  • Sustainably Sourced: Blackbutt is commonly harvested from sustainably managed forests, making it a more environmentally friendly choice compared to certain other materials.
  • Blackbutt timber has a very straight grain. It accepts oil very well and is considered  easy to maintain.



  • Maintenance. Like any natural timber decking, blackbutt requires regular maintenance to keep it in good condition. It will need periodic cleaning, sanding, and resealing or staining to protect it from weathering, UV damage, and moisture absorption.
  • Cost: Blackbutt decking is generally more expensive than some other decking options, which can impact the overall project cost.

  • Weathering: Without proper maintenance, blackbutt decking can fade, gray, and develop cracks over time, especially if exposed to harsh weather conditions.

  • It has a high tannin content and may leach when it becomes wet.
