Yes, a groove can be routed into a Trex decking board using the Trex Groove Cutter/Router, which can be purchased online. The Trex-branded router is specifically designed for creating grooves in Trex and other composite decking materials, ensuring a precise and clean cut for Hidden Fasteners. If you don't have access to the Trex- branded router, you can also use any 5/16” cut height carbide router bit with a ¼” shank, which is compatible for routing grooves into Trex boards.

Using the right tools, such as the Trex Groove Cutter or the recommended carbide router bit, ensures the groove is accurately milled without damaging the material. The groove will be perfectly sized for Trex's Hidden Fastener system, providing a sleek, fastener-free appearance on your deck. Whether using the Trex-branded router or a compatible bit, it's essential to follow proper cutting techniques to avoid overheating and ensure a clean, smooth finish. Always refer to the manufacturer's guidelines for optimal results when routing Trex decking.

When choosing fireplaces and fire pits, there are various options, each with distinct benefits and considerations. Here are our recommendations for safe installation on Trex decking:

For gas-burning fire pits/fireplaces, these are typically installed by cutting around the Trex decking, not directly on top of it. A fire-resistant material is placed underneath, and a protective stone wall or similar material is used to contain the fire and shield the decking from heat. Gas fireplaces should not be placed directly on Trex decking without proper protection. Propane tables are generally safe, as they don't produce downward heat. Trex Outdoor Furniture also offers propane tables to complement their furniture collections.

For wood-burning fire pits, these should not be placed directly on Trex decking unless a heat barrier is used. While we don’t have a specific recommendation for heat barriers, many are available on the market. It's important to note that Trex can soften at temperatures as low as 176°F, and the intense heat or embers from a wood-burning fire can damage the decking.

The unyielding shell of our high-performance decking—Trex Transcend Lineage, Trex Transcend, Trex Enhance and Trex Select—means it never needs painting or staining. The rich color and protective finish are engineered into the shell, and the shell is designed to remain free of rotting, splitting, splintering and insect damage for the duration of the warranty. Painting Trex decking may void your warranty.
