Composite board has many advantages in fire prevention, thermal insulation and other aspects. During construction, we should pay attention to the treatment of the base wall. First, it is to make the bonding of composite board more firm, and second, it is also to ensure that the quality of the project is not affected. Let's introduce how to deal with the base wall.

一、在施工前，有必要整理墙体底层上残留的浮灰、脱模剂油污等，同时，对剪力墙外表的混凝土凸起、空鼓和疏松等部位进行处置，外墙上各种施工时预留的孔洞应填塞密实。

1、 Before construction, it is necessary to sort out the residual floating ash, release agent and oil stain on the bottom layer of the wall. At the same time, the concrete bulges, hollows and looseness on the surface of the shear wall shall be disposed, and the holes reserved during construction on the outer wall shall be filled tightly.

二、张贴岩棉复合板的底层外表，其平整度误差应不超越4mm,当外表平整度超越答应误差时，应对凸出部位打磨找平、凹进部位进行修补（当修补厚度超越6mm时，用1:2.5水泥砂浆抹灰处置、修补厚度<6mm时，可用粘结砂浆实施修补），以确保墙面平整度误差在4mm内。此外，阴阳角应方正且上下顺直。

2、 The flatness error of the bottom surface of the rock wool composite board posted shall not exceed 4mm. When the surface flatness exceeds the allowable error, the protruding parts shall be polished and leveled, and the concave parts shall be repaired (when the repair thickness exceeds 6mm, it shall be plastered with 1:2.5 cement mortar. When the repair thickness is less than 6mm, it can be repaired with bonding mortar), so as to ensure that the flatness error of the wall is within 4mm. In addition, the internal and external corners shall be square and straight up and down.

三、为确保它与底层墙面的粘结力，底层墙面的含水率应<10%.墙面含水率的现场简便测定办法为：取透明塑料纸平铺墙面，用胶带将塑料纸四边封住，过2~4h后若塑料纸内呈结露水，则表明基面含水率>10%,不宜施工。

3、 In order to ensure its adhesion with the bottom wall, the moisture content of the bottom wall shall be less than 10%. The simple on-site measurement method of wall moisture content is: take transparent plastic paper to lay the wall, seal the four sides of the plastic paper with adhesive tape, and if there is dew in the plastic paper after 2 ~ 4h, it indicates that the moisture content of the base surface is more than 10%, which is not suitable for construction.

以上就是对复合板的基层墙面施工处理方法的介绍。在进行墙面处理的时候大家一定要掌握正确的处理方法，将墙面进行合理的打磨，确保墙面的平整度，特别是一些霉点的问题，只有处理干净后在进行粘贴才可以起到好的使用效果。

The above is the introduction of the construction treatment method of the base wall of the composite board. When dealing with the wall, we must master the correct treatment methods, polish the wall reasonably, and ensure the flatness of the wall, especially some mildew problems. Only after cleaning, can we have a good use effect.
