Cracking can occur in portland cement stucco. Cracking is generally not caused by labor failure nor material defect in the stucco and can be minimized by following sound design and construction practices such as: proper installation of lath, proper incorporation of stress relief joints in the construction, proper sand gradation for field mixed stucco, proper proportioning of stucco mix ingredients, use of the minimum amount of water in the stucco mix for placement of stucco, avoiding the use of excess water, moist curing of the stucco after it has been applied, additional application of base coat adhesive cement along with fiberglass reinforcing mesh, and proper sequencing of construction to avoid stresses in the freshly placed stucco.
Efflorescence is a normal occurrence in portland cement based products and can affect final appearance of finish products installed over stucco. For use on vertical above grade walls only. Do not use below grade or on roofs or roof-like surfaces.
