Does Sto Powerwall Stucco have fibers in it, and, if so, what do they do?
Yes, Sto Powerwall Stucco has fiber reinforcement. The fibers resist tensile stress, particularly during the early stages of strength development of the stucco. The fibers help to resist tensile stress from plastic shrinkage of the stucco, as well tensile stresses that may occur when the stucco is in service. By resisting tensile stress the fibers reduce the risk of cracking in the stucco.
