DECKING

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.

Fascia Installation Recommendations

** 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.
