Decide on your final deck design.
Prepare and set the frame based on you desired deck layout.
Temporarily fix your edge cap, apply James Hardie Joint Sealant over the joists and place the first board.
Place the double winged base jointers over each joist and fix the screws ¾ of the way, then place the second board and tighten the screws all the way.
Place the next row of base jointers, then the following board and fix the base jointer all the way. Repeat the process until the deck is complete. Ensure there is a 10mm gap between the first deck board and the house.
Remove the temporarily fixed edge cap and seal the deck – refer to HardieDeck sealing guide (PDF, 1.87MB) for full details.
Install the snap-in top strips and the selected edge caps along the deck perimeter.
