Wet the edge of the old stucco so it won't suck moisture out of the patch and weaken the bond between old and new. Scoop fist-size wads of wet stucco onto a brick trowel and toss them against the wire lath until it's completely covered. Smooth the mix with a finishing trowel, then pack it against the edge of the existing stucco with a brick trowel. Keep adding more material until this layer is about 1/2 inch below the existing stucco surface.
