Is Cumaru Wood a Smart Decking Choice? Here’s What You Should Know

Creating a beautiful outdoor space involves picking the right material for your deck. Cumaru wood, also called Brazilian Teak, is becoming popular for decks because it’s really tough, looks great, and can handle outdoor conditions well. But is Cumaru wood truly a smart decking choice? In this blog post, we’ll delve into the characteristics, advantages, and considerations associated with Cumaru wood decking to help you make an informed decision for your outdoor project.

The Beauty of Cumaru Wood

Cumaru wood, native to South America, boasts a rich and luxurious appearance that can transform your outdoor space into a stylish haven. With a beautiful range of golden to reddish-brown hues, Cumaru decking adds warmth and character to any environment. The wood’s fine grain and interlocking texture further enhance its visual appeal, making it a sought-after choice for homeowners looking to achieve a timeless and elegant deck design.

Exceptional Durability

One of the most compelling reasons to consider Cumaru wood for decking is its remarkable durability. Cumaru is renowned for its high density and natural oils, which contribute to its exceptional resistance to rot, decay, and insect damage. This inherent strength allows Cumaru decking to withstand the harshest outdoor conditions, including heavy foot traffic, extreme weather, and constant exposure to UV rays. As a result, Cumaru wood has a longer lifespan compared to many other decking materials, making it a smart investment for homeowners looking for a lasting solution.

Natural Resistance

One of the standout features of Cumaru wood is its natural resistance to moisture absorption and fungal growth. This resistance is due to the wood’s high oil content, which acts as a protective barrier against water penetration. As a result, Cumaru decking is less likely to warp, crack, or split over time. Additionally, its resistance to fungi and mold growth ensures that your deck remains aesthetically pleasing and safe for outdoor activities.

Low Maintenance Requirements

Choosing Cumaru wood for your decking project also means opting for a material that demands minimal maintenance. Cumaru’s natural oils help maintain its colour and integrity without constant intervention, unlike other wood species requiring regular sealing or staining. A simple cleaning routine involving mild soap, water, and a soft brush is typically sufficient to keep your Cumaru deck looking its best. This low-maintenance aspect of Cumaru wood makes it an attractive choice for homeowners seeking a hassle-free outdoor living space.

Environmental Considerations

While Cumaru wood offers an array of benefits, it’s important to consider the environmental impact of your decking choice. Cumaru is a tropical hardwood, and its popularity has led to concerns about deforestation and unsustainable logging practices in some regions. However, some hardwood suppliers offer Cumaru wood that is certified by organizations such as the Forest Stewardship Council (FSC), indicating responsible and sustainable sourcing. When considering Cumaru wood for your decking, be sure to research hardwood suppliers that prioritize ethical and eco-friendly practices to minimize negative environmental impacts.

Cost Considerations

As with any building material, cost is a factor that homeowners must consider. Cumaru wood tends to be moderately priced, falling between the more budget-friendly options like pressure-treated lumber and the higher-end choices like ipe wood. While the initial cost of Cumaru decking may be higher than some alternatives, its durability and longevity can offset the upfront expenses by reducing the need for frequent replacements or repairs. When evaluating costs, it’s important to weigh the long-term benefits of Cumaru wood against your budget constraints.

Installation and Maintenance Challenges

While Cumaru wood offers numerous advantages, it’s essential to be aware of potential challenges associated with its installation and maintenance. Due to its high density, Cumaru wood can be more difficult to cut and install compared to softer woods. Specialized tools and expertise may be required to achieve the desired results. Additionally, while Cumaru’s natural oils contribute to its resistance to decay, they can also make it more difficult for stains and finishes to adhere effectively. Proper preparation and application techniques are crucial to ensure a successful finish that lasts.


In the quest to create a stunning and enduring outdoor living space, Cumaru wood presents itself as a compelling option for decking material. However, when evaluating Cumaru wood for your decking project, conducting thorough research, consulting with professionals, and selecting a reputable hardwood supplier are key steps to ensuring a successful outcome. By weighing the benefits against the challenges and making an informed choice, you can create a beautiful and resilient outdoor space that enhances the value and enjoyment of your home for years to come.
