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.
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.
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.
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.
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.
