I built my first composite decking picnic table last summer for my backyard. My kids wanted a sturdy table for picnics, and I wanted something easy to clean and weather-proof. This project was fun, simple, and saved money compared to buying a fancy outdoor table. In this article, I’ll share how you can build your own table. You’ll learn what composite decking is, get a step-by-step guide, and find tips to make it easy. Whether you’re new to DIY or a pro, this guide is for you. Let’s get started!
What Is a Composite Decking Picnic Table?
A composite decking picnic table is an outdoor table made from composite decking boards. These boards mix wood fibers and plastic to create a strong, weather-resistant material.
Why Use Composite Decking?
Composite decking is perfect for outdoor furniture. It doesn’t rot, splinter, or need much care. Unlike wood, it handles rain, sun, and snow well. I love that my table stays smooth and looks great all year.
How It Compares to Wood
Wood tables are cheaper but need constant upkeep. They can crack or warp in bad weather. Composite decking lasts longer and saves time. However, it costs more upfront and can get hot in direct sun.
Why Build Your Own Composite Decking Picnic Table?
Building your own table is rewarding. You save money and make exactly what you want. My table fits our small deck perfectly, and I picked a color to match our house. Plus, it’s a fun project to do with family or friends.
Benefits of a DIY Picnic Table
- Customizable: Choose the size, shape, and color you like.
- Durable: Composite decking lasts 25+ years with little maintenance.
- Eco-Friendly: Many brands, like Trex, use recycled materials.
Drawbacks to Consider
- Cost: Composite boards are pricier than wood.
- Weight: The table is heavy, so plan to build it near its final spot.
- Heat: Dark colors can get hot in the sun, so choose wisely.
Step-by-Step Guide to Building a Composite Decking Picnic Table
Here’s how I built my 8-foot-long picnic table. It seats eight people and uses composite decking for the tabletop and benches. Follow these steps for your own.
Tools You’ll Need
You don’t need fancy tools. Here’s what I used:
- Drill: For screws and pre-drilling holes.
- Saw: A circular saw cuts composite boards cleanly.
- Measuring Tape: To get sizes right.
- Screws: Use stainless steel screws for composite decking.
- Safety Gear: Wear gloves and safety glasses.
Materials for Your Table
I used affordable materials from my local hardware store. Here’s a list:
| Material | Quantity | Cost (Approx.) |
|---|---|---|
| Composite Decking Boards (5.5” x 8’) | 6 | $150–$200 |
| Pressure-Treated 2x4s | 8 | $40–$60 |
| Stainless Steel Screws | 100 | $20–$30 |
| Wood Glue | 1 bottle | $5 |

Step-by-Step Instructions
- Plan Your Design: I sketched a simple 8’x3’ table with two benches. A diagram of the frame and board layout helps.
- Build the Frame: Use 2x4s to make a rectangular table frame. Add diagonal braces for strength.
- Cut Composite Boards: Measure and cut six 8-foot boards for the tabletop and benches.
- Attach Boards: Screw boards to the frame using stainless steel screws. Pre-drill holes to avoid cracking.
- Build Benches: Make two bench frames with 2x4s. Attach composite boards on top.
- Secure Everything: Check all screws are tight. Add glue for extra hold.
- Place Your Table: Move it to your backyard or deck. Get help—it’s heavy!

Tips for Success from My Experience
I made mistakes building my first table. Here are tips to help you:
- Choose Light Colors: Dark composite boards get hot in the sun. I picked a light gray to keep it cool.
- Check Joist Spacing: Composite decking sags if supports are too far apart. Use 12-inch spacing, not 16 inches.
- Use Hidden Fasteners: Screws on top can look messy. Try hidden clips for a cleaner look.
Common Mistakes to Avoid
- Skipping Pre-Drilling: Composite boards can split without pre-drilled holes.
- Using Wrong Screws: Regular screws rust. Always use stainless steel.
- Ignoring Weight: Plan where to place the table before building—it’s hard to move.
Comparing Composite Decking Brands
Not all composite decking is the same. I compared three popular brands for my project.
| Brand | Pros | Cons | Cost per Board |
|---|---|---|---|
| Trex | Durable, eco-friendly, many colors | Expensive, can get hot | $25–$35 |
| Fiberon | Affordable, recycled materials | Less rigid, may sag | $20–$30 |
| TimberTech | Long warranty, premium look | Very pricey | $30–$45 |

Cost-Saving Ideas
Building a composite decking picnic table can be budget-friendly. Here’s how I saved money:
- Use Leftover Boards: I used scraps from a deck project to cut costs.
- Shop Sales: Check Home Depot or Lowe’s for deals on composite boards.
- Build Smaller: A 6-foot table uses fewer boards than an 8-foot one.
Safety Tips for Your Project
Safety matters when building. Follow these tips:
- Wear gloves to avoid splinters from cutting boards.
- Use safety glasses when sawing composite decking.
- Work in a shaded area to avoid overheating boards during assembly.
Other Options for Outdoor Tables
If composite decking isn’t right for you, try these:
- Cedar Wood: Looks great, resists weather, but needs sealing yearly.
- Pressure-Treated Wood: Cheap but may splinter or warp over time.
- PVC Decking: Lightweight and durable but more expensive than composite.
| Material | Durability | Maintenance | Cost |
|---|---|---|---|
| Composite Decking | High | Low | $$$ |
| Cedar Wood | Medium | High | $$ |
| Pressure-Treated Wood | Low | High | $ |
