Many houses will have cracks on the wall after living for a long time. Most of the cracks are irregularly distributed with different depths. Some surface putty cracks and internal mortar plastering layer cracks are very shallow, which is difficult to observe. Some cracks are deep to the bottom of mortar plastering layer (wall surface). If the putty is not firmly combined with the mortar surface, the surface putty is easy to peel and fall off, which seriously affects the appearance.

提醒你墙面裂缝大体分为四种

Remind you that there are four kinds of wall cracks

1.墙体裂缝：裂缝随地基的变动呈现不均匀的分布。

1. Wall cracks: cracks are unevenly distributed with the change of foundation.

这是由于墙体沉降变形造成的。解决办法：

This is caused by wall settlement and deformation. terms of settlement:

1).如果是建筑一直沉降变形、不要忙于修补,等待不再变形时再进行修补。

1) If the building has been settlement and deformation, do not be busy with repair, and repair it when it is no longer deformed.

2).修补要根据裂缝形状、密度大小而采取多种方案,可用开槽修补或者加网格布修补,一定用高弹腻子粉。

2) Various schemes shall be adopted for repair according to the crack shape and density. It can be repaired by slotting or adding grid cloth, and high elastic putty powder must be used.

2.粉刷层裂缝：找平砂浆柔性不够,表现为比较大的龟裂纹,一般是均匀的分布。用高弹腻子或双组份弹性腻子粉满批,分别修补。

2. Cracks in the painting layer: the leveling mortar is not flexible enough, which is characterized by large turtle cracks, which are generally evenly distributed. Repair with high elastic putty or two-component elastic putty powder.

3.保温层裂缝：一般呈现不规则的裂缝是比较常见。是由于苯板的收缩变形、网格布、砂浆、不正确的施工等很多原因造成的。解决办法应根据裂缝的大小及分布不同而定,如果比较严重,有必要加贴网格布或网布,如果不严重就用双组份的柔性腻子粉满批。

3. Insulation layer cracks: generally, irregular cracks are common. It is caused by the shrinkage deformation of benzene plate, grid cloth, mortar, incorrect construction and many other reasons. The solution shall be determined according to the size and distribution of cracks. If it is serious, it is necessary to paste mesh cloth or mesh cloth. If it is not serious, it shall be fully approved with two-component flexible putty powder.

4.腻子层裂缝：一般表现为细微的龟裂纹,均匀分布,注意不是缝是纹,纹和缝是有区别的。

4. Cracks in putty layer: generally, there are slight turtle cracks, which are evenly distributed. Note that the cracks are not cracks, but lines, and cracks are different.
