COMPOSITE DECKING INSTALLATION

For any decking where two boards meet end-to-end over a joist, add additional blocking (figure 2). Allow 1/4" distance between all decking material and any permanent structure or post. After all of the decking has been attached, snap a chalk line (white or yellow chalk recommended) flush with or up to 1-1/2" out from the deck framing and trim with a circular saw.
All wood and composite decking products require proper ventilation and drainage to ensure their longevity. When using a minimum 2x6 joist standing on edge and the suggested 1/4" side gap,decks made of plastic wood there should be a 2" clear space between the bottom edge of the joists and grade in order to allow for proper ventilation. Adequate drainage is also needed to prevent water from pooling under the deck.
Fasteners
For ease of installation, the Equator fastener fits into the slot on each side of the deck board to eliminate pre-drilling and provide a timeless, fastener-free deck surface. The deck boards require traditional fasteners on the outside and inside edges of the deck.
Begin by fastening the outside edge of the first board to the rim joist every 16". For this, we recommend using 2-1/2" corrosion-resistant, composite wood deck screws. These screws help prevent the common “mushroom” effect that sometimes occurs when using standard fasteners. It can also reduce the amount of pre-drilling and countersinking.
If using ordinary coarse-thread deck screws, always pre-drill a pilot hole and countersink prior to driving screws. Screws should be driven flush with the surface. Do not over- tighten. Use one fastener per board every 16". For any decking where two boards meet end-to-end over a joist, add additional blocking. Always pre-drill a pilot hole when fastening within 1-1/2" of board ends, whether using composite or wood screws. Do not over- tighten screws at board ends.
On the other side of the board, place an Equator hidden fastener into the slot and center on the joist (figure 3). Install a #8, 2" stainless steel screw at a 90° angle through the Equator fastener and drive flush. Do not over- tighten. The fastener wings must remain level with the joist for the next board to fit correctly (figure 4). Install one Equator fastener at each joist location. Slide the next board into place so the wings on the previous fasteners fit into the slot on the side of the board. Make sure the side gap between the boards is 1/4".

To keep the interior boards from moving over time, we
recommend pinning the boards at the center of their length using a #8, 2" stainless steel screw. This holds the deck board in place at the center of each board and allows the decking to expand/contract at the ends of the boards.
Pre-drill in the slot of the deck board with an 1/8" drill bit ([url=http://www.woodplasticcompositepanel.com/project-case/composite-panels-for-cladding]Composite panels for cladding for sale[/url]). Drive screw into the slot so it’s flush with the bottom of the groove (figure 5). This will allow you to properly fit an Equator hidden fastener into the slot. Install Equator hidden fastener clip over the screw and centered over the joist. Fasten using a #8, 2" stainless steel screw at a 90° angle through the Equator hidden fastener and drive flush with the clip (figure 6). The fastener wings must remain level with the joist for the next board to fit correctly (figure 4).
Install one Equator fastener at each joist location along the length of the board. For installations where deck boards are butted end-to-end at the joist, we recommend adding an 8" block and using an Equator hidden fastener clip at the end of each board (figures 7 and 8). Be sure to gap the boards as previously described.best composite decking suppliers Repeat the process for each board until the outside edge of the final board is fastened with screws. Use fascia to conceal the board profile and inhibit board movement over time. If no fascia is being used, the entire perimeter of the deck should be fastened to the rim joist with screws. Use two fasteners at the end of each board. These screws will be inconspicuous once the railing is installed.
