- Does this board need painting or sealing?
- No. Composite decking is made to be left bare; it does not need stain or sealant. Clean it with soap and water.
- What fasteners does a grooved board use?
- Grooved boards take hidden clips that sit in the side grooves and screw to the joist. The clips are sold separately and must match the board's groove.
- Can I use it for a ground-level deck?
- Yes, but keep it off the soil on a framed substructure with airflow underneath, as you would any composite deck.
- How does it compare with Trex's other lines?
- Signature is Trex's premium line, with a more natural look and a longer warranty than the entry-level Enhance line. Whidbey is the gray colorway.
- How far apart should joists be?
- Follow Trex's installation guide for the Signature line; composite is more flexible than wood, so spacing matters. Check the guide before framing.
- Where is the Trex Signature Whidbey Grooved Composite Deck Board 1-in x 6-in x 20-ft cheapest?
- At The Home Depot, for $195.20, as of our latest check.
