Now that you have put the deck frame and joists in place, you can install the decking of your deck. You have a variety of materials to choose from - pressure-treated wood, redwood, cedar and even artificial wood. Your choice will be based on your preference for aesthetics versus ease of maintenance. Make sure that butt joints in the decking do not occur in the same joists for two consecutive rows. Make sure that they are staggered for both aesthetic and structural reasons.
