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.

提醒你墻面裂縫大體分為四種

Remind you that there are four kinds of wall cracks

1.墻體裂縫：裂縫隨地基的變動呈現不均勻的分布。

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

這是由于墻體沉降變形造成的。解決辦法：

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

1).如果是建筑一直沉降變形、不要忙于修補,等待不再變形時再進行修補。

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).修補要根據裂縫形狀、密度大小而采取多種方案,可用開槽修補或者加網格布修補,一定用高彈膩子粉。

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.粉刷層裂縫：找平砂漿柔性不夠,表現為比較大的龜裂紋,一般是均勻的分布。用高彈膩子或雙組份彈性膩子粉滿批,分別修補。

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.保溫層裂縫：一般呈現不規則的裂縫是比較常見。是由于苯板的收縮變形、網格布、砂漿、不正確的施工等很多原因造成的。解決辦法應根據裂縫的大小及分布不同而定,如果比較嚴重,有必要加貼網格布或網布,如果不嚴重就用雙組份的柔性膩子粉滿批。

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.膩子層裂縫：一般表現為細微的龜裂紋,均勻分布,注意不是縫是紋,紋和縫是有區別的。

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.
