Cement stucco is durable and stands up to harsh outdoor elements. The two main categories of stucco include traditional or cement stucco and newer synthetic stucco.

The reaction of the gypsum with water gives off heat through crystallization and causes the plaster to harden. Plaster contains cement and sand-like stucco but uses gypsum as a binder. Stucco withstands the rigors of weather, unlike plaster. These additives typically work with one-coat stucco only. Additives such as acrylic fibers or fiberglass strands, added to the stucco mixture, improve the strength of the stucco, and help prevent cracking and chipping. Modern stucco contains Portland cement, sand, and lime with additional materials used for strength or aesthetics.
