A water draining exterior wall structure for a building having a building framework is disclosed. The wall structure includes a plurality of prefabricated panel sections secured to a building framework to form a wall surface. Each panel section includes a support structure for attachment to the building framework which has a water barrier deck substantially co-extensive with the support structure. In addition, a plurality of fascia panels overly the water barrier deck and are attached thereto by beads of silicone adhesive so that a gap is provided between the deck and each fascia panel. A gutter is also provided in each panel which extends along the bottom of each panel section for collecting water entering the gap and carrying the collected water to a drainage end of said gutter so that water can drain out of said panel section. Water drainage dams are also provided, each of which is located in a joint between adjacent panel sections below the drainage end of a gutter of each panel section. Each dam (1) receives water having drained out of the gutter(s) located immediately above it and (2) directs the received water out of the joint in which said dam is located, thereby draining water from said wall structure.
