Slip a 2-inch plastic washer over a 1 5/8-inch drywall screw, and drive it into the lath through one of the adhesive-filled holes. The screw pulls the lath against the plaster's back side while the washer gives the screwhead a wide clamping surface. Plant washers about 8 to 12 inches apart on both sides of the crack.
