Durability - Portland Cement Association

Portland cement plaster (stucco) should not be confused with exterior insulation and finish systems (EIFS) or synthetic stucco systems that may have performance problems, including moisture damage and low impact-resistance. Synthetic stucco is generally a fraction of the thickness of portland cement stucco, offering less impact resistance.
