The Best Above Ground Pool Deck Material List for 2024

Selecting the right materials for your above ground pool deck is the foundational step in transforming a basic swimming structure into a durable, attractive, and safe outdoor living space. A well-planned deck provides a stable surface for sunbathing, a clean barrier against muddy pool entry, and a defined area for setting up lounge chairs and dining setups. This guide serves as a comprehensive material list, breaking down every component required from the ground up to ensure a professional and long-lasting installation.

Understanding the Role of the Decking Itself

The decking material is the most visible element of your project, and choosing between composite, wood, or rigid plastic laminate involves balancing aesthetics, maintenance, and budget. Composite decking is currently the top choice for many DIYers and contractors due to its resistance to rot and splinters, while traditional pressure-treated pine remains a cost-effective option if you are comfortable with annual sealing. Regardless of your choice, calculating the square footage correctly is critical to avoid wasted materials and ensure you have enough fasteners and edging to complete the job.

Composite and Engineered Wood

• Composite decking boards (usually 1" thick)
• Hidden fasteners or stainless steel screws
• End caps and transition pieces
• Ripping blades for clean cuts around the pool frame

Traditional Wood Options

• Pressure-treated 2x6 or 5/4 x 6 decking
• Galvanized or coated deck screws
• Waterproof wood sealer or stain
• Plastic shims for leveling

The Structural Foundation: Frame and Support

Above ground pools rely on a robust frame to maintain shape, and the deck must integrate seamlessly with this structure to distribute weight evenly. You will need additional 2x4 or 4x4 lumber to build a perimeter ledger board and support beams that lock into the pool walls. Lag screws and structural adhesive are essential for creating a rigid connection that prevents the deck from shifting or squeaking under the weight of multiple people and furniture.

Ground Preparation and Moisture Control

Before any wood touches the ground, you must address drainage and moisture control to prevent premature decay. A layer of crushed stone or gravel acts as a stable base and prevents the wood from sitting in pooled water. Landscape fabric placed between the stone and the soil stops weeds from pushing up through the cracks, while plastic edging or retaining blocks keep the stone contained and create a neat border around the pool area.

Safety and Aesthetic Border Components

To secure the perimeter of the deck and hide the pool's side wall, you will need specific edging materials that lock the structure together. Aluminum pool deck edging is popular for its rust-free properties and sleek appearance, providing a clean transition between the wood and the pool wall. Additionally, installing deck skirting—using materials like lattice boards or slatted wood panels—hides the pump and plumbing while deterring pests from nesting underneath the structure.

Hardware, Fasteners, and Installation Supplies

The longevity of your deck depends heavily on using the right fasteners. Standard nails are unsuitable for outdoor decks; you must use coated or stainless steel screws designed to resist rust. Post base brackets and concrete pier blocks are necessary if you plan to install deck posts for a handrail or shade structure. For comfort underfoot, consider adding adhesive foam weather sealant around the top of the pool wall to cushion the transition between the deck and the pool edge.

Finishing Touches and Long-Term Maintenance

Once the deck is constructed, the final materials ensure the space is welcoming and safe. Outdoor area rugs can define seating areas and add color, while durable cushions made for marine or outdoor use withstand sun and rain. For lighting, solar path lights or low-voltage LED strips installed under the deck rim create ambiance and prevent nighttime trips. Finally, keeping a supply of deck cleaner and a standard tool kit on hand will help you address scratches and reseal the surface efficiently, ensuring your deck remains a central feature of your backyard for years to come.
