Laying Decking Part 3 of 5
Buy decking boards that are long enough to span the width of the deck, if possible. If boards must be butted
Buy decking boards that are long enough to span the width of the deck, if possible. If boards must be butted end-to-end, make sure to stagger the joints so they do not overlap from row to row. Predrill the ends of boards to prevent screws or nails from splitting the wood.
Install decking so that there is a 1⁄8" gap between boards to provide drainage. Boards naturally “cup” as they age. Lay boards with the bark side facing down, so that the cupped surface cannot hold standing water.
General installation instructions for decking materials are shown here. Always follow the installation methods recommended by the manufacturer of the product you select.
T-clip Decking - Step 1
Push another deck board tightly against the front T-clips, attach T-clips at front of the new board, then fully tighten the previous set of T-clips. Add another deck board and repeat the process, to the end of the deck.
T-clip Decking - Step 2
Cover exposed deck board ends. Miter cut corners of the facing, and drill pilot holes 3⁄4 the diameter of the screws. Attach with 3" galvanized deck screws.
Fiberglass Deck Systems - Step 3
Place a length of retaining clips on top of the first joist. Center it on the joist and fasten with 2" galvanized deck screws. Attach lengths of retaining clips to the subsequent joists, so that the clips are perfectly aligned with the first length of clips, creating straight rows.
Fiberglass Deck Systems - Step 4
Place the open face of a decking board perpendicular to the joists, resting on top of a row of clips. Apply firm pressure to the top of the deck board until the decking snaps into place over the retaining clips. Work along the row, snapping the deck board in place. Attach the remaining deck boards in place, snapping each onto a row of retaining clips.
Fiberglass Deck Systems - Step 5
Cut the overhanging ends of the decking boards flush with the outside joists, using a circular saw with a fresh carbide‑tipped blade or a masonry cut-off disc.
Fiberglass Deck Systems - Step 6
Use 2" galvanized deck screws to attach the pre-fabricated facing, covering the exposed hollow ends and creating a decorative trim. Cover the screw heads with the screw caps.
Decking for a Curve - Step 7
Install decking for the square portion of the deck, then test-fit decking boards on the curved portion. If necessary, you can make minor adjustments in the spacing to avoid cutting very narrow decking boards at the end of the curve. When satisfied with the layout, scribe cutting lines on the underside of the decking boards, following the edge of the rim joist.
Decking for a Curve - Step 8
Remove the scribed decking boards, and cut along the cutting lines with a jigsaw. Install the decking boards with deck screws, and smooth the cut edges of the decking boards with a belt sander, if necessary.
Use a Template - Step 9
Lay the decking boards so the ends overhang the rough opening. Make a cardboard template to draw a cutting line on the deck boards. (When framing for a tree, check with a tree nursery for adequate opening size to provide space for growth.) Cut the decking boards along the marked line, using a jigsaw.
How to Install Decking with Spiked Clips - Step 10
Drive a spiked clip into the edge of wood decking at joist locations. Use the included fastening block to prevent damage to the spikes.
