Garapa Decking for Terrace Projects in Bismarck, ND

Understanding Garapa Hardwood for Terrace Applications

Garapa (Apuleia leiocarpa), also known as Brazilian Ash, is a tropical hardwood originating from Brazil. It is characterized by its golden color, which can add a warm and inviting aesthetic to any outdoor space. This natural hue can be maintained with appropriate finishing or allowed to gradually weather to a silver-gray patina over time, depending on homeowner preference and exposure to the elements.

Beyond its appearance, Garapa is valued for its durability. It is considered very durable and resistant to termites and weather changes, which is a key factor for outdoor applications like terraces that are exposed to varying conditions. Its air dry density is 4.11 lbs/bf. These attributes contribute to its potential for a long lifespan.

For decking, Garapa is described as scratch and slip resistant, with minimal splintering. These characteristics are important for creating a comfortable and safe walking surface, especially in high-traffic terrace areas. It is important to note that while resistant, no material is entirely impervious to wear or damage.

Designing a Defined Terrace Space with a Picture Frame Border

A picture frame border is a design technique where the perimeter boards of a deck or terrace run perpendicular to the main field boards, creating a distinct visual frame. This approach can be particularly effective on terraces, helping to define the space and provide a clean, finished edge.

When planning a picture frame border with Garapa decking, consider the dimensions of your terrace and the available board profiles. Garapa is available in profiles such as 5/4"x6" (actual 1" x 5.5"), with lengths ranging from 3 to 24 feet. This variety allows for flexibility in designing the border and field sections.

The contrast in grain direction between the border and field boards can enhance the visual appeal, drawing attention to the terrace's boundaries. This design choice also provides a practical benefit by eliminating visible end grain along the main perimeter, potentially offering a tidier appearance.

Planning Your Garapa Decking Layout: A Worked Example

Consider a hypothetical terrace project in Bismarck, ND, measuring 12 feet by 16 feet. The homeowner desires a picture frame border that is one board wide around the entire perimeter, with the main field boards running parallel to the 16-foot dimension.

For this example, we will use 5/4"x6" Garapa decking boards (actual dimensions 1" x 5.5").

First, calculate the border boards. The two long border boards will be 16 feet long each. The two short border boards will need to fit between the long border boards. Since each long border board is 5.5 inches wide, the effective length for the short border boards becomes 12 feet - (2 * 5.5 inches) = 12 feet - 11 inches = 11 feet 1 inch. For material ordering, these would typically be ordered as 12-foot boards to allow for precise cutting on site.

Next, calculate the main field boards. The width of the field area will be 12 feet - (2 * 5.5 inches) = 11 feet 1 inch. The length of the field boards will be 16 feet - (2 * 5.5 inches) = 15 feet 1 inch. This calculates to roughly 23 boards. For a 15-foot 1-inch length, 16-foot boards would be a practical purchase. Always round up to ensure sufficient material.

Total boards for this hypothetical example: 2 x 16-foot boards for long borders, 2 x 12-foot boards for short borders (cut to fit), and 23 x 16-foot boards for the field. This amounts to approximately 27 boards. This is an area-equivalent calculation; actual purchase quantities may vary based on available lengths, cut waste, and any specific installation requirements. Always consult with your installer and supplier for precise quantities.

Remember to account for waste, typically 10-15%, especially with custom cuts for borders and any potential defects or miscuts. Always order slightly more material than the exact calculated quantity.

Considerations for Bismarck, ND Climate

Bismarck, ND, experiences a continental climate with significant temperature fluctuations, including cold winters and warm summers. Materials chosen for outdoor projects must be capable of handling these extremes.

Garapa's natural resistance to weather changes makes it a suitable option for such environments. While it resists decay and insects, proper installation practices, including adequate ventilation beneath the deck, are crucial to ensure its long-term performance.

The golden color of Garapa can be maintained through regular cleaning and application of UV-inhibiting finishes, or it can be allowed to weather naturally. In a climate with strong sun exposure, the natural weathering process may occur more rapidly without protective finishes. Homeowners should consider their desired aesthetic and maintenance commitment when planning their project.

Maintenance and Longevity of Garapa Decking

Garapa hardwood is known for its natural resistance to rot, decay, and insects, which means it does not require constant chemical treatments. This can reduce the ongoing maintenance burden compared to some other decking materials.

To maintain the original golden color, regular cleaning and the application of a penetrating oil finish with UV inhibitors are recommended. Without such maintenance, Garapa will gradually lighten and turn a silvery-gray over time. Both appearances are valid aesthetic choices, but it's important to understand the commitment involved in maintaining the original color.

Regular cleaning helps prevent the buildup of dirt, mildew, and other debris that can trap moisture and potentially lead to staining or degradation. Sweeping the deck regularly and occasional washing with a mild cleaner and water can help keep the surface in good condition.

Complementary Products for Your Terrace Project

Beyond the decking boards themselves, several other products can enhance the functionality and aesthetics of your Garapa terrace. Consider durable fasteners, whether visible face screws or hidden fastening systems, designed for hardwood applications. Hidden fasteners can provide a clean, unblemished surface, complementing the refined look of a picture frame border.

For the sub-structure, treated lumber or other durable framing materials are essential to provide a stable and long-lasting foundation for your Garapa deck. Ensuring proper joist spacing and support is critical for the performance and safety of the deck.

Finally, explore options for railings or privacy screens that complement the golden tones of Garapa. Materials like metal, glass, or even other hardwoods can create a cohesive and inviting outdoor space. Consider these elements early in the design phase to ensure a unified aesthetic.

Before you order

• Define your terrace dimensions and desired layout, including any border elements.
• Determine if you prefer Garapa's natural golden tone or its weathered silver-gray patina.
• Research appropriate fasteners for Garapa hardwood (face-fastened or hidden).
• Plan for adequate ventilation beneath the deck structure, especially in Bismarck's climate.
• Consider the structural requirements for your terrace, including joist spacing and support.
• Factor in a waste percentage (typically 10-15%) when calculating material quantities.
• Evaluate complementary products such as railings, lighting, or privacy screens.
• Confirm local building codes and regulations for terrace construction in Bismarck, ND.

Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
