Wall construction is a necessary project in construction. The construction quality of this project is related to the construction quality of the whole house, which can not be ignored. So what is the plastering thickness of cement mortar? What should be paid attention to in the construction process?

　　每層抹灰厚度(每次厚度)根據各地區的基礎材料、灰漿品種、工程件質量標準及氣候條件確定。每道工序的厚度一般控制如下:

　　The thickness of each plastering layer (each thickness) shall be determined according to the foundation materials, mortar varieties, quality standards of engineering parts and climatic conditions in each region. The thickness of each process is generally controlled as follows:

　　(1)水泥砂漿厚度每次5 ~ 7mm。

　　(1) the thickness of cement mortar is 5 ~ 7mm each time.

　　(2)石灰砂漿或混合砂漿厚度每次7 ~ 9mm。

　　(2) the thickness of lime mortar or mixed mortar is 7-9mm each time.

　　(3)抹灰表面覆蓋麻刀灰、紙棱灰、石膏灰等，壓扁壓實后麻刀灰厚度不超過3mm;紙棱灰和石膏灰不得大于2mm。

　　(3) the plastering surface shall be covered with pockmark ash, paper edge ash, gypsum ash, etc., and the thickness of pockmark ash after flattening and compaction shall not exceed 3mm; the thickness of paper edge ash and gypsum ash shall not exceed 2mm.

　　(4)混凝土板及大型模板建筑的墻面、樓板底部用膩子刮，厚度為2 ~ 3mm。

　　(4) the wall and floor bottom of the concrete slab and large formwork building shall be puttied with a thickness of 2 ~ 3mm.

　　(5)如采用聚合物水泥砂漿、水泥混合砂漿噴毛基層、紙筋灰漿覆蓋，并與膨脹珍珠巖水泥抹面砂漿，總厚度3 ~ 5mm。

　　(5) if polymer cement mortar, cement mixed mortar are used to spray the base course, paper reinforced mortar is used to cover, and the mortar is plastered with expanded perlite cement, with a total thickness of 3 ~ 5mm.

　　(6)板條厚度、金屬網用麻刀灰、紙筋抹灰每次3 ~ 6mm。

　　(6) the thickness of the lath, the metal mesh shall be plastered with pockmarks and paper bars for 3 ~ 6mm each time.

　　水泥砂漿與水泥混合砂漿抹灰層，應等前一層抹灰層凝結后，可施后一層;石灰砂漿抹灰層，應等一層七至八萬后，才能敷一層。

　　For the plastering layer of cement mortar and cement mixed mortar, one layer can be applied after the previous plastering layer is set; for the plastering layer of lime mortar, one layer can only be applied after 70000-80000.

　　水泥抹面砂漿應分層施工。當抹灰總厚度大于或等于35mm時，應采取加固措施。應加強不同材料基體交界處表面的抹灰處理，防止開裂。使用加筋網片時，加筋網片與基材搭接寬度不得小于100mm。

　　The cement plaster mortar shall be constructed in layers. When the total thickness of plastering is greater than or equal to 35mm, reinforcement measures shall be taken. The plastering treatment of the surface at the junction of different materials should be strengthened to prevent cracking. When using reinforced mesh, the overlapping width of reinforced mesh and base material shall not be less than 100mm.

　　當抹灰厚度過大時，容易產生鼓形、脫落等質量問題。在不同材料的交界處，連接處表面抹灰層容易開裂，吸水收縮不一致。

　　When the plastering thickness is too large, it is easy to produce quality problems such as bulging and falling off. At the junction of different materials, the plastering layer on the joint surface is easy to crack, and the water absorption and contraction are inconsistent.

　　水泥抹面砂漿注意事項

　　Precautions for cement plaster mortar

　　抹項目質量的關鍵是債券堅決不開裂空鼓和脫落,如果債券不強,會有缺陷如空鼓、開裂和脫落,這將減少墻上的保護作用和影響裝飾效果。經調查分析，產生裂縫、空鼓、抹灰層脫落的主要原因是襯底表面不干凈。

　　The key to the quality of plastering project is that the bond will not crack, empty and fall off. If the bond is not strong, there will be defects such as empty, cracked and fall off, which will reduce the protection effect of the wall and affect the decoration effect. Through investigation and analysis, the main reasons for cracks, hollowing and falling off of plastering layer are unclean substrate surface.

　　如基體表面的灰塵和疏松物、脫模劑和油污等影響抹灰粘結牢固材料不完全清潔;基體表面光滑，抹灰前表面未被磨破。抹灰前基體表面不透水，抹灰后砂漿中的水分很快被基體吸收，使砂漿質量差，使用不當;一旦抹灰過厚，干縮較大，會影響抹灰層和基體的粘結牢度。

　　For example, the dust and loose substance, mold release agent and oil stain on the surface of the base affect the bonding material of plastering, which is not completely clean; the surface of the base is smooth, and the surface is not worn before plastering. Before plastering, the surface of the base is impervious to water. After plastering, the moisture in the mortar is quickly absorbed by the base, resulting in poor quality and improper use of the mortar. Once the plastering is too thick and the shrinkage is large, it will affect the bonding fastness of the plastering layer and the base.

　　以上是濟南抹面砂漿公司關于水泥抹面砂漿厚度及注意事項的介紹，希望能對了解水泥抹面砂漿施工有所幫助。另外，這種方法更適合南方潮濕的空氣，一般外墻用水泥砂漿。對于干燥地區，使用混合砂漿。本文來源：http://m.zzmdwxsh.com

　　The above is the introduction of Jinan plastering mortar company on the thickness and precautions of cement plastering mortar, hoping to be helpful to understand the construction of cement plastering mortar. In addition, this method is more suitable for the humid air in the south. Generally, cement mortar is used for the exterior wall. For dry areas, use mixed mortar.
