Zusammenfassung:The invention relates to the field of mortar, and particularly discloses plastering mortar and a preparation method thereof. The plastering mortar comprises the following raw materials in parts by weight: 110 to 130 parts of cement; 30 to 50 parts of shale macadam; 350 to 380 parts of fine sand; 30 to 50 parts of water; 5 to 15 parts of a thickening agent; and 10 to 20 parts of a reinforcing agent. The preparation method comprises the following steps: step 1, mixing the cement, the thickening agent and the reinforcing agent to obtain a first-stage mixture; step 2, mixing the first-stage mixture, fine sand and shale macadam to obtain a second-stage mixture; and step 3, mixing the second-stage mixture with water to obtain the plastering mortar. According to the plastering mortar, the shale macadam and the fine sand are adopted as aggregate of the plastering mortar, the shale macadam has micro-nano pores, and the micro-nano pores of the shale macadam have a water storage effect and absorb air reserved between th
