What tools are required?

No special tools are required when using pre-grooved deck boards, just a drill with screwdriver tip. When using decking without the grooved edge, a router with proper bit will be needed to create a groove in board edge at each joist or along the entire edge of the deck board.

45° angle installation

Where deck is in the walled corner of the house: Always start with small triangular piece of decking in that corner and work your way out. When installing Trex HideawayTM fasteners, offset the center 1/2" towards the long point of joist so screw will not exit side of joist when driven.

How to do a butt seam

First, install a small framing board (10 - 12") alongside the joist in which the seam is going to land. Install additional fastener into previous board above small framing block. Line up your first board in the center of the joist and the small framing board. Install fasteners and screws at each joist of the first board including the joist at the seam. Then install your second board in the same fashion, and place a second fastener at the seam attaching it to the small framing block. Make sure you follow end-to-end gapping specifications.

To use the Trex Hideaway Fasteners on unslotted boards:

Use a router with the proper routing bit to create a groove at every intersection of the deck board and support joists, as well as entire edge of the board.

How to replace a board

  • Make two parallel cuts down the center of the board to be replaced, and remove the center piece.
  • Remove the remaining pieces of decking from the tabs.
  • Using a claw hammer bend the tab, on the side of the board with the screw heads showing, downward so that it does not interfere with the spacer tab.
  • Position new board into place, and carefully slide onto remaining tabs, once fully installed the deck board will drop into position.
  • Once board is set into position, secure using a 1/8th inch drill bit, place the bit into the seam of the board and into the groove, and predrill a pilot hole through the board at a 45° angle
  • Install a stainless steel finish screw through groove into joist to hold the board in place.
