One is that a large area of plaster should be laid before the standard. Plastering shall be carried out in layers of 5mm to 7mm. Plastering mortar and cement mortar, each thickness of 7mm ~ 9mm. When the total thickness of plastering layer is more than 35mm, corresponding reinforcement measures shall be taken.

　　第二點是如果使用水泥砂漿和水泥砂漿抹灰器，應等到前一層抹灰器設置好后，才可以允許抹下一層抹灰。如果用石灰砂漿抹灰，則應等到前一層七至八層干燥后，再抹后一層。

　　The second point is that if cement mortar and cement mortar plasterer are used, the next layer of plastering shall not be allowed until the previous layer of plasterer is set. If plastering with lime mortar, wait until the first seven to eight layers are dry before plastering the second layer.

　　第三點是抹灰強度的底面不能低于抹灰強度的面。

　　The third point is that the bottom surface of plastering strength cannot be lower than the surface of plastering strength.

　　第四點是調好水泥砂漿混合后，應在初凝前用完，通常有硬砂擋，即砂漿開始凝結后不能繼續使用。

　　The fourth point is that after the cement mortar is mixed, it should be used up before the initial setting, and there is usually a hard sand block, that is, the mortar can not be used after it starts to set.

　　目前，灰漿出廠檢驗包括初凝時間、抗壓強度、密度、稠度、收縮率。抹灰干混砂漿有三個相關標準和規范:自凝加氣混凝土砌體砂漿和抹灰砂漿(jc890-2001)、建筑砂漿基本性能試驗方法(jgj70-1990)、水泥砂漿干縮試驗方法(JC/ t603-1995)。性能測試包括四個方面:材料的標準稠度、砂漿的保水性能、砂漿的分層程度和流動性。

　　At present, the factory inspection of mortar includes initial setting time, compressive strength, density, consistency and shrinkage. There are three relevant standards and specifications for plastering dry concrete mortar: self setting aerated concrete masonry mortar and plastering mortar (jc890-2001), basic performance test method for building mortar (jgj70-1990), and dry shrinkage test method for cement mortar (JC / t603-1995). The performance test includes four aspects: the standard consistency of the material, the water retention performance of the mortar, the stratification degree and the fluidity of the mortar.
