How to Build a Trex Deck Over a Concrete Patio

Transform your concrete patio into a stylish and functional outdoor living space with a Trex deck. Trex is a composite decking material known for its durability, low maintenance, and resistance to rot, fading, and insects. Building a Trex deck over a concrete patio is a straightforward project that can be completed in a few days with the right tools and materials.

Materials You'll Need:

Trex decking boards
Trex joists
Trex fascia boards
Trex stair treads (if needed)
Trex hidden fasteners
Screws or nails
Level
Measuring tape
Circular saw or miter saw
Drill
Concrete anchors (if needed)

Step 1: Prepare the Concrete Patio

Clean the concrete patio and inspect it for any cracks or uneven areas. Repair any damage before proceeding. Make sure the patio is completely dry and level.

Step 2: Install the Trex Joists

Lay the Trex joists perpendicular to the direction you want the decking boards to run. Space the joists evenly, typically 12-16 inches apart. Secure the joists to the concrete with concrete anchors or screws, if necessary.

Step 3: Install the Trex Decking Boards

Start by installing a Trex fascia board along the perimeter of the deck. This will provide a finished edge. Then, lay the Trex decking boards on top of the joists. Use Trex hidden fasteners to secure the boards to the joists.

Step 4: Install the Trex Stair Treads (Optional)

If your deck includes stairs, install the Trex stair treads. Start by securing the stringers to the concrete patio and joists. Then, attach the stair treads to the stringers with screws or nails.

Step 5: Finish the Deck

Install any railings or other accessories you desire. Seal the deck with a Trex deck sealer to protect it from the elements and enhance its appearance.

Tips for Building a Trex Deck Over Concrete:

Use a level to ensure that the deck is level in all directions.
Allow for expansion and contraction by leaving a small gap between the decking boards.
Use stainless steel screws or nails to prevent corrosion.
Follow the Trex installation instructions carefully for the best results.
