What Is Merbau Wood?

Merbau wood, originating primarily from Southeast Asia and parts of Australia, is a highly sought-after material, especially in the construction and carpentry industries. Known scientifically as Intsia bijuga, this hardwood is renowned for its remarkable strength and aesthetic appeal.

Characteristics of Merbau Wood

Merbau is distinguishable by its rich, dark reddish-brown color, which often deepens with age. This wood also features a unique interlocked grain pattern that not only enhances its visual appeal but also contributes to its structural integrity. A notable aspect of merbau wood is its high oil content, which gives the surface a natural sheen and helps in maintaining its condition over time.

Why Choose Merbau for Decking?

The choice of merbau wood for decking is influenced by several compelling factors. Firstly, its natural beauty and warm tones make it an attractive option for outdoor spaces, blending well with natural landscapes and enhancing the overall aesthetic of homes and commercial properties. Secondly, the durability of merbau wood is exceptional. It is capable of withstanding heavy foot traffic, making it ideal for decks and patios that are frequently used.

Durability and Resistance

One of the strongest selling points of merbau wood is its resilience. It holds up remarkably well against the elements, making it suitable for various climates, from humid tropical settings to colder, wetter conditions. This durability is due to its dense structure and natural oils, which protect it from decay, rot, and damage caused by pests such as termites. These properties ensure that merbau wood decking remains in excellent condition for many years, often outlasting other materials without the need for frequent treatments or repairs.

Color and Aesthetic Appeal

Merbau’s coloration is not just beautiful but also versatile, able to complement a wide range of design choices and styles. Over time, the wood can shift to a more subdued brown, retaining its elegance and providing a timeless look to any installation.

Merbau wood stands out in the realm of decking materials due to its combination of beauty, durability, and resistance to weather and pests. Its ability to maintain its integrity and appearance with minimal maintenance makes it a popular choice among homeowners and builders alike. For those looking to invest in a deck that lasts, merbau provides a robust, stylish, and practical solution that is hard to surpass.

By understanding the characteristics and benefits of merbau wood, consumers and professionals can make informed decisions about their decking materials, ensuring both longevity and aesthetic appeal in their outdoor spaces.

Why Does Merbau Need Special Decking Oil?

Merbau is a popular hardwood choice for decking due to its durability and striking appearance. However, to maintain its aesthetic appeal and longevity, special care, particularly in choosing the right decking oil, is essential. Here’s a detailed explanation of why Merbau needs special decking oil, addressing its natural oil content, potential issues if not maintained properly, and the importance of selecting the appropriate oil.

The Natural Oil Content of Merbau

Merbau wood is naturally rich in oils, which significantly contributes to its durability and resistance to weather conditions. These natural oils serve as a protective barrier, helping to repel water and prevent the wood from drying out too quickly, which can lead to cracking and splitting. The presence of these oils also gives Merbau its vibrant, deep color, enhancing its overall visual appeal. However, over time and exposure to the elements, the natural oils can deplete, causing the wood to lose its luster and protection. This depletion underscores the need for regular application of a quality decking oil, tailored to replenish and reinforce the natural oil content of Merbau.

Common Issues with Unmaintained Merbau Decking

If Merbau decking is not regularly maintained, several issues can arise that detract from both its functionality and aesthetic quality. Common problems include:

Fading: Prolonged exposure to sunlight can cause the rich colors of Merbau to fade, resulting in a dull, washed-out appearance.

Cracking and Splitting: As the natural oils diminish, the wood becomes more susceptible to moisture changes, leading to cracks and splits.

Greying: Without proper oiling, Merbau can start to grey due to oxidation and UV exposure.

These issues not only affect the look of the deck but can also compromise its structural integrity over time.

The Importance of Choosing the Right Decking Oil

To counteract the natural depletion of oils and combat the potential issues associated with exposure, selecting the right decking oil for Merbau is crucial. A specially formulated decking oil for Merbau can:

1. Enhance Appearance: High-quality oil can restore and enhance the natural color of Merbau, making it look vibrant and new.

2. Protect Wood: It provides a protective layer that minimizes water absorption and UV damage, significantly extending the life of the deck.

3. Prevent Deterioration: Regular application helps to prevent common issues like cracking, splitting, and greying, ensuring the deck remains in excellent condition.

Decking oil formulations specifically designed for Merbau typically contain UV stabilizers, mildew inhibitors, and other components that help maintain the wood’s natural beauty and structural integrity. It’s important to follow the manufacturer’s recommendations for application intervals to ensure optimal protection and appearance.

In conclusion, the natural oil content of Merbau, while beneficial for its initial quality and durability, requires regular supplementation through appropriate decking oils to maintain its condition and appearance.

Types Of Decking Oil Suitable For Merbau

When it comes to enhancing and protecting your Merbau decking, choosing the right type of decking oil is crucial. Merbau, a popular hardwood known for its durability and rich color, requires specific care to maintain its natural beauty and longevity. In this article, we will explore the different types of decking oils available—water-based, oil-based, natural, and synthetic—and discuss their advantages and disadvantages, particularly about Merbau wood. We’ll also highlight which types are most effective in preserving the aesthetic and structural qualities of this exquisite hardwood.

Water-Based Decking Oil


Water-based decking oils are known for their quick drying times and low odor. They penetrate Merbau wood well, providing a clear finish that enhances the wood’s natural color without significantly altering it. Water-based oils are environmentally friendly, with lower volatile organic compounds (VOCs), making them a safer choice for families and pets.


While water-based oils provide a durable finish, they might not be as long-lasting as oil-based options. They may require more frequent reapplication to maintain the wood’s appearance and protection.

Oil-Based Decking Oil


Oil-based decking oils are highly effective in deeply penetrating the dense fibers of Merbau. They tend to enhance the grain and natural hues of the wood, providing a rich, glossy finish. Additionally, oil-based oils typically offer superior moisture resistance and durability, reducing the frequency of maintenance.


The main drawback of oil-based decking oils is their longer drying times. They can also emit strong odors and higher levels of VOCs during application, which might be a concern in terms of health and environmental impact.

Natural Decking Oil


Natural decking oils, often made from plant-based sources and essential oils, are ideal for homeowners seeking an eco-friendly option. These oils not only provide good protection and enhancement of Merbau’s natural characteristics but also maintain a safer environment around the home due to their non-toxic nature.


Natural oils might not provide as robust a barrier against weather elements and wear as synthetic oils. They can also be more expensive and may require more frequent applications.

Synthetic Decking Oil


Synthetic decking oils are designed to offer the best in durability and protection. They are specifically formulated to resist fading, staining, and moisture, making them an excellent choice for high-traffic areas or regions with severe weather conditions.


These oils might alter the natural color of Merbau decking more significantly than other oils. They can also be more challenging to apply evenly and are generally less environmentally friendly due to chemical additives.

Choosing the right decking oil for Merbau can significantly impact the wood’s longevity and appearance. Water-based and natural oils offer environmental benefits and ease of use, making them suitable for those prioritizing safety and minimal environmental impact. Oil-based and synthetic oils, however, provide enhanced durability and moisture resistance, ideal for decks exposed to harsher conditions.

For most Merbau decking, oil-based decking oils are generally recommended due to their deep penetration and long-lasting protection. However, the final choice should consider the specific needs of your decking area, including exposure to elements, traffic levels, and personal preferences for maintenance frequency and environmental impact. By selecting the appropriate oil, you can ensure that your Merbau deck remains a stunning and durable feature of your outdoor space.

How To Choose The Best Decking Oil For Merbau

When it comes to enhancing and protecting your merbau decking, choosing the right decking oil is crucial. Merbau is a popular hardwood that is known for its durability and beautiful rich color. However, to maintain its appearance and longevity, you need the right oil that can protect it from the elements and enhance its natural beauty. Here’s a comprehensive guide to help you choose the best decking oil for your merbau deck.

Criteria for Selecting the Right Decking Oil

1. UV Protection: One of the first considerations should be how well the oil can protect the wood from ultraviolet (UV) rays. Continuous exposure to sunlight can cause the wood to fade and deteriorate over time. Look for oils that specify UV protection to ensure that your deck maintains its color and durability.

2. Moisture Resistance: Water resistance is another critical factor. The ideal oil will create a barrier that repels water, preventing rot, mold, and mildew. This is particularly important in damp or humid climates.

3. Ease of Application: Consider how easy the oil is to apply. Some oils require more preparation and a more meticulous application process, while others are more straightforward. Oils that are easy to apply and quick to dry will save you time and effort.

4. Finish: Decking oils can vary in the type of finish they provide, from matte to glossy. Your choice will depend on the aesthetic you prefer for your deck. Matte finishes generally offer a more natural look, while glossy finishes provide a high sheen that highlights the wood’s natural grains.

Factors to Consider

Climate: The climate in your area plays a significant role in choosing the right oil. For example, decks in sunny areas will benefit from oils with enhanced UV protection, while decks in rainy locations will need better moisture resistance.

Existing Condition of the Deck: Assess the current condition of your deck. If it’s new and in good shape, you might opt for a lighter oil that enhances its natural color. For older decks, a heavier oil might be needed to restore and protect the wood.

Personal Preferences: Finally, consider your personal preference for the deck’s appearance. Whether you prefer a glossy or a matte finish can significantly influence your choice of oil.

1. Preparing Your Merbau Deck for Oil Application

Gather Your Materials and Tools

Before you begin, ensure you have all the necessary materials and tools

  • Decking oil suitable for merbau
  • High-quality brush, roller, or sprayer
  • Sandpaper (120-150 grit)
  • Clean rags
  • Broom and hose or pressure washer
  • Protective gloves and eyewear

Clean the Deck

Start with a thorough cleaning of your deck. Remove all furniture and sweep away any loose dirt or debris. For the best results, use a pressure washer or a stiff broom and a dedicated deck cleaning solution to remove old finishes, stains, and any mold or mildew. Allow the deck to dry completely, which typically takes 24-48 hours.

Sand the Surface

Once dry, sand the deck lightly with 120-150 grit sandpaper. This will smooth out imperfections and help the decking oil penetrate more effectively. Remember to sand in the direction of the wood grain to avoid scratches. Clean up all sawdust with a broom or blower.

2. Applying Decking Oil on Merbau

Choose the Right Conditions

For the best results, choose a dry day with temperatures between 10°C and 30°C. Avoid oiling in direct sunlight or when rain is expected within 24 hours.

Apply the Decking Oil

Stir the oil thoroughly before and during use to ensure a consistent finish. Using a brush, roller, or sprayer, apply the decking oil along the length of the deck boards, working on a few boards at a time to avoid lap marks. Ensure an even application, paying particular attention to end grains and joints. Allow the oil to penetrate for the time specified by the manufacturer, usually 10-15 minutes, then wipe away any excess oil with a clean rag to prevent pooling and uneven drying.

Second Coat (if needed)

Depending on the oil brand and your deck’s condition, a second coat might be necessary for optimal protection. Refer to the product’s guidelines for drying times between coats.

3. Safety Precautions

While applying decking oil, wear protective gloves and eyewear to avoid skin and eye irritation. Ensure your work area is well-ventilated, especially if you’re using solvent-based oils. Keep children and pets away from the deck during the application and drying process.

4. Maintenance Tips to Extend the Life of Your Deck

To maximize the life and look of your oiled merbau deck:

  • Regularly sweep and clean the deck to remove dirt and debris.
  • Reapply decking oil every 12 to 24 months, or as needed, based on weather exposure and foot traffic.
  • Address spills and stains promptly to prevent permanent damage.

By following these detailed steps, you’ll ensure your merbau deck not only looks beautiful but also stands up against time and weather. Proper application and regular maintenance of decking oil are key to prolonging the life and beauty of your outdoor living space.
