Abstract: Disclosed is a fastening system and method for securing a sheathing board to an associated framing member. The system includes a feedband for retaining a series of fasteners and a powered drill for sequentially driving the fasteners. The feedband is made from a membrane of a polymeric compound. As the fastener is driven into the sheathing board, a portion of the membrane tears away from the surrounding feedband and becomes seated beneath the fastener. This acts to seal the penetration point and prevent water intrusion and otherwise prevents deterioration of the sheathing board.
