Wait seven days, then remove the plastic and mist the patch with water. Mix up a batch of stucco following the second-coat recipe, and trowel on a 3/8-inch-thick coat, working from the bottom up. Pack down the edges with a brick trowel. Wait for the wet sheen to disappear, then trowel the patch smooth, just below the level of the existing stucco. Cover again with a plastic sheet.
