Step 4: Attaching Diagonal Bracing

Place a 2"x4" board diagonally behind the 4"x4" posts. With a pencil, mark the angle at each end and cut. Attach the 2"x4" diagonal board by toe-screwing two - 2 1/2" deck screws from each side. Repeat the process, alternating angles from section to section. Bracing should be placed between the posts along the outside perimeter of the deck, and the 4"x4" posts perpendicular to the pool. The 2"x4" bracing boards along the outside perimeter of the deck will need a compound miter cut (a cut angled in two directions - vertically and horizontally).

See Splash Pool Deck Plan for locations of 2"x4" bracing boards.
