Trex Decking for Backyard Gathering Spaces in Minneapolis, MN

Understanding Trex Collections for Your Gathering Space

Trex offers several collections, each with distinct aesthetics and features, all sharing a core of 95% recycled content and a protective three-side cap. For a backyard gathering space, the choice of collection can define the mood and style.

The Enhance® lines, including Basics and Naturals, provide a balance of value and performance. Enhance Basics offers traditional colors like Clam Shell, Beach Dune, and Saddle, while Enhance Naturals provides multi-tonal, wood-grain inspired options such as Foggy Wharf and Rocky Harbor. These are suitable for projects where a natural wood look is desired without extensive maintenance.

For an elevated aesthetic and enhanced performance, the Select® Earth Tones and Transcend® lines (Earth Tones and Tropical) offer richer colors and textures. Select Earth Tones, with colors like Pebble Grey and Woodland Brown, combine high-performance shell technology with nature-inspired hues. The Transcend lines, like Transcend Earth Tones (Gravel Path, Rope Swing) and Transcend Tropical (Havana Gold, Island Mist), are designed for a luxurious finish and vibrant color retention, ideal for a premium gathering space that serves as a focal point.

All Trex boards are 1 inch by 5.5 inches in profile and come in 12, 16, and 20-foot lengths, available in both grooved and square-edge options. This consistency across lines simplifies planning and allows for creative design combinations.

Coordinating Dimensions and Layout for Social Flow

A successful gathering space requires thoughtful dimensioning and layout. Consider how people will move, sit, and interact. For example, a common recommendation for dining areas is a minimum of 10x10 feet to accommodate a table and chairs comfortably, allowing for chair pull-out and circulation. Lounge areas might require similar dimensions, depending on the furniture.

When planning with Trex boards, which are typically 12, 16, or 20 feet long, aim to minimize waste. For a hypothetical 16x20-foot deck, using 20-foot boards for the longer dimension can reduce butt joints. If your deck is 16 feet wide, you could use a single 16-foot board. For a 20-foot width, two 12-foot boards with a seam, or a single 20-foot board if available, would work. The placement of joists and blocking is critical for supporting seams and ensuring proper board spacing.

Consider a picture-frame border using square-edge boards for a refined look. This often requires additional planning for mitered corners and proper support underneath. The fascia, available to match Trex decking, is used to conceal the deck's substructure and create a finished edge. Ensure you account for the fascia's dimensions when calculating the overall deck footprint and material quantities.

Fastening Systems: Hidden Clips vs. Face Screws

The choice impacts both the aesthetic and the installation process.

Hidden clips provide a clean, fastener-free surface, which is often preferred for gathering spaces where a smooth, uniform look is desired. These clips fit into the grooved edges of the boards and attach to the joists, creating consistent spacing between boards. This method is generally recommended for the main deck surface.

Face screws are used for square-edge boards, typically for perimeter boards, stair treads, or fascia. While visible, modern composite-compatible screws are designed to blend in and minimize mushrooming. When face-fastening, pre-drilling can help ensure a clean appearance and prevent material stress. Always follow the manufacturer's specific instructions for screw type, spacing, and depth to maintain the warranty and ensure structural integrity.

Regardless of the method, proper fastening is crucial for the longevity and stability of your deck, especially in Minneapolis where seasonal temperature fluctuations can affect materials.

Maintenance for Lasting Enjoyment

One of the key advantages of Trex decking is its low maintenance. Unlike traditional wood decks that require regular staining or sealing, Trex boards are designed to resist fading and staining due to their protective three-side cap. The manufacturer specifies a simple soap-and-water wash for routine cleaning, which helps maintain the warranty.

For Minneapolis's climate, which includes snow and ice in winter and humidity in summer, regular cleaning becomes even more important. Debris, pollen, and leaves can accumulate and, if left, potentially lead to mildew or minor discoloration. A seasonal wash, perhaps in spring after the snow melts and again in the fall, can help keep the deck looking its best.

Avoid using harsh chemicals, pressure washers at high settings, or abrasive cleaners, as these can damage the deck surface and potentially void the warranty. Always refer to the specific cleaning guidelines provided by Trex for your chosen collection.

While Trex is designed for durability, proactive maintenance, like promptly clearing snow and ice with a plastic shovel (avoiding metal), can further protect your investment.

Worked Example: A 14x18-Foot Deck in Transcend Tropical

Let's plan a hypothetical 14x18-foot deck for a Minneapolis backyard gathering space, using Trex Transcend Tropical in "Island Mist." This collection offers a rich, multi-tonal look.

For the main deck surface, we'll use grooved boards. The 18-foot length is a standard Trex board length, so we can run these boards parallel to the 14-foot dimension to minimize seams.

To cover the 14-foot width with 5.5-inch wide boards, we'll need approximately 14 feet / (5.5 inches / 12 inches/foot) = 30.54 boards. Since we need full boards, we'll purchase 31 boards. We'll use hidden clips for fastening.

For the perimeter, we will add a picture frame border using square-edge boards in the same Island Mist color. This requires four pieces for the outer frame. For the 18-foot sides, we'll need two 18-foot square-edge boards. For the 14-foot ends, we'll need two 14-foot square-edge boards. Note that 14-foot boards are not a standard length, so we would purchase two 16-foot square-edge boards and cut them to 14 feet, leaving reusable 2-foot offcuts.

Finally, for fascia, we'll need to cover the perimeter. The deck has two 18-foot sides and two 14-foot ends. We would purchase two 20-foot fascia boards (cut to 18 feet with 2-foot offcuts) and two 16-foot fascia boards (cut to 14 feet with 2-foot offcuts). Always confirm exact dimensions and availability of fascia boards when ordering.

Before you order

• Select a Trex collection (Enhance, Select, Transcend) that matches your aesthetic and performance needs.
• Determine the desired dimensions of your gathering space, accounting for furniture and traffic flow.
• Plan board layout to minimize waste, considering standard Trex board lengths (12, 16, 20 ft).
• Decide on hidden clips for main deck surfaces or face screws for perimeter and stairs.
• Account for fascia boards to finish the deck edges.
• Confirm local building codes and structural requirements for your deck project in Minneapolis.
• Consider future maintenance and cleaning requirements for your chosen Trex collection.

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.
