Trex Golden Hour Composite Decking 12ft Grooved

When building a premium outdoor space, the details matter. The Trex Golden Hour Composite Decking 12ft Grooved is designed for homeowners and contractors who demand a pristine, unblemished deck surface. Unlike traditional square-edge boards that require top-down drilling, these grooved boards feature a channel along both sides. This allows you to slide in Trex Hideaway® Universal Hidden Fasteners, securing the board to the joist invisibly. The result? A smooth, splinter-free deck that looks like a high-end interior hardwood floor.

Unmatched Performance & Sun-Smart Technology

As outdoor living experts, we highly recommend the Trex Enhance Naturals line for its perfect balance of aesthetics, durability, and value.

• SunComfortable™ Heat-Mitigation: The Golden Hour colorway is engineered with specialized heat-mitigating technology. While all decking absorbs heat in direct sunlight, this specialized formulation reflects more solar energy, allowing it to stay cooler to the touch compared to traditional, darker composite boards.

• Scalloped Profile: The underside of the board features a scalloped (ridged) design. This reduces the overall weight of the board, making it as easy to handle and cut as traditional lumber, without sacrificing structural integrity.

• Hassle-Free Maintenance: Forget the annual chore of sanding, staining, and sealing. A simple wash with warm water and mild dish soap is all you need to maintain that gorgeous, golden-hour glow year after year.

Expert Installation Note: For standard residential deck builds, ensure your joists are spaced no more than 16 inches on center (O.C.) when installing these boards perpendicularly. Always use approved composite hidden fasteners (such as Trex Hideaway® or FastenMaster Cortex) to ensure your 25-year warranty remains fully valid.

Frequently Asked Questions

Do I have to use hidden fasteners with Trex Golden Hour Composite Decking 12ft Grooved boards?

Yes. The grooved profile is specifically manufactured to house hidden fastener clips. If you wish to face-screw your deck boards, or if you are installing a “picture frame” border around the perimeter of your deck, you should purchase the Square Edge version of this board.

Does this Trex Golden Hour Composite Decking 12ft Grooved get hot in the summer?

Golden Hour utilizes Trex’s heat-mitigating technology, making it cooler than early-generation composites. However, like any material left in direct summer sun, it will get warm. Care should always be taken with bare feet on hot, sunny days.

Can I pressure wash Trex Golden Hour Composite Decking 12ft Grooved?

Yes, but use caution. Only use a fan-tip nozzle, keep the wand at least 8 inches from the deck surface, and ensure your pressure washer is set under 3100 PSI to avoid damaging the protective composite shell.
