Fascia
4. Install appropriate number of recommended fasteners as per pattern shown above, as overall size of fascia after being cut may be smaller than that of the standard size, thus the number of screws used every 18” may be different in different areas. Ensure screws are installed 1" from edge of stringer (do not install screws in the end of the stair tread).
5. If the fascia is not wide enough to cover the stair stringer, a secondary piece of fascia may need to be cut accordingly and installed. Install using one recommended fascia fastener on or near the space r.
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 TREX RECOMMENDED FASCIA RECOMMENDED 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 . **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.
