Get expert advice on installing edge composite decking, including best practices, tools needed, and common mistakes to avoid.
Edge composite decking is a popular choice among homeowners for its durability, low maintenance, and aesthetic appeal. Unlike traditional wood decks, composite decking materials are made from a combination of recycled plastic and wood fibers, making them resistant to rot, insects, and moisture. Installing edge composite decking requires careful planning and the right tools to ensure a long-lasting and attractive result. This comprehensive guide will walk you through the installation process step-by-step, providing essential tips and recommended tools to help you achieve a successful outcome.
The first step in installing edge composite decking is preparing the site. Ensure that your deck foundation is level and secure. You can use a concrete pad or pressure-treated wood joists as a base. The substructure should be at least 1.5 inches above ground level to prevent water damage. Check local building codes and regulations to ensure compliance with safety standards.
Once the site is ready, it’s time to install the joists and framing. Use 2×8 or 2×10 pressure-treated lumber for the joists, spaced no more than 16 inches apart. Secure each joist with galvanized screws or nails. For added stability, consider adding blocking between the joists at regular intervals. Ensure that all fasteners are countersunk below the surface of the wood to avoid damaging the composite boards during installation.
Begin laying the composite boards perpendicular to the joists, starting at one end of the deck. Leave a small gap (about 1/8 inch) between each board to allow for expansion and contraction due to temperature changes. Use composite deck screws or hidden fasteners to secure the boards. Hidden fasteners are ideal for achieving a clean, seamless look. Drive screws into the center of each board to minimize the risk of splitting.
Cut the composite boards to fit the edges using a circular saw with a fine-tooth blade. When cutting, always wear protective gear, including gloves and safety glasses. After installation, apply a sealant or finish if desired to enhance the appearance and longevity of your deck. Regular cleaning and maintenance will also help preserve the beauty of your edge composite decking over time.
