Here are the steps to follow when installing fascia and risers: Fascia: Install screws at a maximum inch interval, with three screws across the face at each interval.

Fascia need to be installed with the same gaps and specialty fasteners to allow for ventilation and prevent cracking. The sections below discuss the specifics of gaps and fasteners. Because many of the Trex and Fiberon composite decking products are made to mimic the natural color variations of wood decking, they recommend that you lay out your complete deck before applying composite decking fasteners.

This will help identify places where color variations are too similar or visually jarring. To increase the visual appeal of the deck, consider alternating the direction of the wood grain from one length to the next. For Fiberon deck boards, the wood grain pattern repeats every 44 inches. Try staggering the arrangement when laying composite decking to achieve the desired visual effect.

When arranging your decking, be sure to leave the required gaps end-to-end and between boards, as well as between the outside deck board and any permanent structures. These gaps are critical to allow for drainage as well as expansion as outdoor temperatures rise. Both Trex and Fiberon have recommended gap widths based on the outdoor temperature at the time of installation:. If your deck is built with metal framing and joists, they will expand differently than wood.

As a result, minimum gapping for your deck board will be different as well. Low maintenance cellular PVC is available in board and sheets and comes in smooth or textured finishes.

Cellular PVC products come in white but can be painted, if desired. Here is a nice example of how you can install skirting, fascia and an access door under your deck. Install a nailer board between support posts to attach the bottom side of the skirting or install 2x4 vertical framing flush on the outside of the frame. Use a piece of scrap material to space your skirt boards.

Next, fasten each skirt board to the top and bottom of the skirt frame. Keep the bottom of the skirt at least 1" above the ground. Start each section using a level. Use the level every boards to make sure the boards are still plumb. Fasten the vertical 2x4 framing to the deck frame using screws. This technique could also be used to support all the skirt framing if you don't have any available support posts to attach to.

Build an access door using a Z brace. Make sure the angle brace starts at the bottom hinge and ends at the latch.
