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，有必要整理墻體底層上殘留的浮灰、脫模劑油污等，同時，對剪力墻外表的混凝土凸起、空鼓和疏松等部位進行處置，外墻上各種施工時預留的孔洞應填塞密實。

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、張貼巖棉復合板的底層外表，其平整度誤差應不超越4mm,當外表平整度超越答應誤差時，應對凸出部位打磨找平、凹進部位進行修補（當修補厚度超越6mm時，用1:2.5水泥砂漿抹灰處置、修補厚度<6mm時，可用粘結砂漿實施修補），以確保墻面平整度誤差在4mm內。此外，陰陽角應方正且上下順直。

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、為確保它與底層墻面的粘結力，底層墻面的含水率應<10%.墻面含水率的現場簡便測定辦法為：取透明塑料紙平鋪墻面，用膠帶將塑料紙四邊封住，過2~4h后若塑料紙內呈結露水，則表明基面含水率>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.

以上就是對復合板的基層墻面施工處理方法的介紹。在進行墻面處理的時候大家一定要掌握正確的處理方法，將墻面進行合理的打磨，確保墻面的平整度，特別是一些霉點的問題，只有處理干凈后在進行粘貼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.
