Abstract: A cementitious composition the properties of which are useful for: a) reducing shrinkage cracking in stucco systems due to excess water present in initial mixing required to achieve adequate slump necessary for application, but not necessary for material hydration b) reducing full thickness cracking as a result of minor structural movement by increasing the flexural strength, c) reducing the time required to place the layers of a three-coat exterior stucco system. The composition of this material is a blend of ASTM C 150 Portland cement, an ASTM C 1328 Plastic (Stucco) cement and a minor amount of a sulfonated naphthalene formaldehyde condensate (SNF), also described as Polynaphthalene sulfonates (PNS) cement superplasticizer, also known as a HRWR (High Range Water Reducer).
