Step 12: Attach the Decking.

Starting from one side of the deck, attach the first 2"x6" surface board flush to the edge of the deck. Along the angled section of the deck, allow the 2"x6" surface boards to extend past the angled end boards by at least one inch. Secure with two 2 1/2" deck screws at the connection of each support board. If the surface boards are pressure treated and wet, position the boards flush against each other (edges touching). Within a few days, a small gap will form as the boards dry and shrink. If the surface boards are cedar, redwood, or composite decking, leave a 1/8" gap between the surface boards.

After all surface boards are secured, use a chalk line to mark a line that follows the angled end boards. With a circular saw, trim the overhanging 2"x6" surface boards so that they're flush with the the angled end boards.
