抹面砂浆厚度到底是多少呢?施工时需要注意什么?

  墙面施工是建筑施工中必须进行的一项工程,本工程的施工质量关系到整个房屋的施工质量,是绝对不容忽视的。那么水泥砂浆的抹灰厚度到底是多少呢?施工过程中需要注意什么?

  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?
  每层抹灰厚度(每次厚度)根据各地区的基础材料、灰浆品种、工程件质量标准及气候条件确定。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)水泥砂浆厚度每次5 ~ 7mm。
  (1) the thickness of cement mortar is 5 ~ 7mm each time.
  (2)石灰砂浆或混合砂浆厚度每次7 ~ 9mm。
  (2) the thickness of lime mortar or mixed mortar is 7-9mm each time.
  (3)抹灰表面覆盖麻刀灰、纸棱灰、石膏灰等,压扁压实后麻刀灰厚度不超过3mm;纸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墙面、楼板底部用腻子刮,厚度为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浆、水泥混合砂浆喷毛基层、纸筋灰浆覆盖,并与膨胀珍珠岩水泥抹面砂浆,总厚度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)板条厚度、金属网用麻刀灰、纸筋抹灰每次3 ~ 6mm。
  (6) the thickness of the lath, the metal mesh shall be plastered with pockmarks and paper bars for 3 ~ 6mm each time.
  水泥砂浆与水泥混合砂浆抹灰层,应等前一层抹灰层凝结后,可施后一层;石灰砂浆抹灰层,应等一层七至八万后,才能敷一层。
  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.
  水泥抹面砂浆应分层施工。当抹灰总厚度大于或等于35mm时,应采取加固措施。应加强不同材料基体交界处表面的抹灰处理,防止开裂。使用加筋网片时,加筋网片与基材搭接宽度不得小于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.
  当抹灰厚度过大时,容易产生鼓形、脱落等质量问题。在不同材料的交界处,连接处表面抹灰层容易开裂,吸水收缩不一致。
  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.
  水泥抹面砂浆注意事项
  Precautions for cement plaster mortar
  抹项目质量的关键是债券坚决不开裂空鼓和脱落,如果债券不强,会有缺陷如空鼓、开裂和脱落,这将减少墙上的保护作用和影响装饰效果。经调查分析,产生裂缝、空鼓、抹灰层脱落的主要原因是衬底表面不干净。
  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.
  如基体表面的灰尘和疏松物、脱模剂和油污等影响抹灰粘结牢固材料不完全清洁;基体表面光滑,抹灰前表面未被磨破。抹灰前基体表面不透水,抹灰后砂浆中的水分很快被基体吸收,使砂浆质量差,使用不当;一旦抹灰过厚,干缩较大,会影响抹灰层和基体的粘结牢度。
  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.
  以上是济南抹面砂浆公司关于水泥抹面砂浆厚度及注意事项的介绍,希望能对了解水泥抹面砂浆施工有所帮助。另外,这种方法更适合南方潮湿的空气,一般外墙用水泥砂浆。对于干燥地区,使用混合砂浆。本文来源:http://www.swdld.cn
  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.
