The paper aims to achieve Proper knowledge of the properties of stone and understanding deterioration factors and deterioration mechanisms are necessary for successful maintenance, protection and suitable conservation interventions. avoiding technical errors that occur during building up the building. These technical errors cause stucco decoration falling. samples from the building (Mohamed Ali house) stone blocks and Crystalline salts are Analyzed by X-ray diffraction & X-ray fluorescence. To be able to interpret the wall damage accurately. Results showed that Halite salt efflorescence occur in vertically stone bedding plane. thermal expansion coefficient of a salt exceeds the surrounding rock stone weathering Exfoliation occur. So incorrect position for building stones, Not perpendicular to Bedding Plane of Sedimentary rocks, This problem must be avoided because its harmful effect to the Stability of Wall Stucco Decoration in Historical Buildings.
