![]() ![]() Install the remaining deck boards using the same techniques, spacing them evenly. Install the next deck board with two screws in each standard joist, spacing the two deck boards by about 1/8 inch apart. Fasten the deck board to the joists with 2-inch deck screws (for 1-inch-thick lumber) or 2 1/2-inch screws (for 1 1/2-inch-thick lumber). Position the holes slightly off-center so they won't interfere with the frame screws. Alternatively, you can place the first and last boards so they overhang the end joists by 1 inch, or so, for a finished look just be aware that you won't have the same overhang at the sides of the frame.ĭrill pairs of pilot holes aligned with each standard joist, with one hole going into the end joist and one into the standard joist. Place one deck board along one long side of the deck frame so it is flush with the outside face of the end joist. Measure all of the 12-foot-long deck boards, and trim any as needed so they are 144 inches each. Do the same to mark the other end joist.Īdd two more standard joists inside the frame so each end is set between a pair of layout lines, making sure the tops of the joists are flush. Drill pilot holes, and fasten through the end joist and into the standard joist with three 3 1/2-inch screws at each end. Measure from the inside of one corner of the frame and make a pair of marks every 16 inches along one of the 12-foot end joists. Place the two end joists over the ends of two of the standard joists to create a 120-inch-by-144-inch rectangle.ĭrill pilot holes, and fasten the pieces together with three 3 1/2-inch deck screws at each corner, using a drill. Measure the two 12-foot 2x8s if they're anything over 12 feet, trim them to exactly 144 inches (lumber often runs a fraction of an inch longer than the nominal dimension in this case, 12 feet). Cut 10 pressure-treated 2x8 boards to length at 117 inches, using a circular saw or power miter saw these are the standard joists. If necessary, you can also build the deck on top of the concrete blocks.
