What will be an ideal response?
Being Portland cement based, stucco shrinks, creating tensile stress in it. Therefore, it needs reinforcement, which is
provided by a lath. The lath is made by stretching a galvanized steel sheet that has been slit at regular intervals, so
that the lath is like a steel mesh. The stucco and lath together behave like a reinforced concrete element.
