T R E X ® FASCIA INSTALLATION RECOMMENDATIONS WHEN USING DECK BOARDS AND COMPOSITE DECKING FASTENERS FOR FASCIA. While Trex prefers the previous methods of attachment for fascia applications, as these are the very best options, there are also other recommendations that can be followed for deck boards being used for fascia. Use two Trex recommended composite decking screws every 12". NOTE THAT FASCIA APPROVED FASTENERS CANNOT BE USED IN THIS APPLICATION. IN ADDITION ALWAYS refer to manufacturer instructions to ensure that recommended screws can be used for fascia applications. The top screw should be placed 1" from the top of the rim joist , and the second screw 1" from the bottom of the rim joist .
T R E X ® FASCIA INSTALLATION RECOMMENDATIONS
GENERAL NOTES: » Trex Fascia utilized around the perimeter of a deck must be gapped with the same requirements as Trex decking to allow for expansion/contraction of the fascia.
» When using 2" x 8" framing, attach fascia using 2 fascia approved fasteners; when using 2" x 10" or larger framing, attach fascia using 3 fascia approved fasteners. Top screw should be placed 1" from the top of the rim joist, the second screw in the center of
the rim joist, and the third screw 1" from the bottom of the rim joist. WHEN USING APPROVED FASCIA FASTENERS: » Approved fascia fasteners can only be used with 1 x 8 or 1 x 12 fascia product and cannot be used with decking products that are being used as fascia trim or stair risers.
**IN ADDITION , also use a weather-resistant, construction-grade adhesive (adhesives that work with wood will work with Trex products) as a SECONDARY fastener when attaching deck boards used for fascia. Remember to wipe away any excess before it dries or is allowed to drip onto other Trex surfaces.

Install 3/16" to 1/4" thick x minimum 1" wide exterior grade spacers (these should be cut the same length as the rim joist), and spaced 9" on center. Install fascia screws as stated below at spacer locations (ensure that spacer screw does not interfere with fascia screw).
Install fascia UNDER decking edges/ends. This will optimize the aesthetics of the installation.
