所謂抹灰層表面的收縮裂縫，是指墻體表面的抹灰出現的一些不規則的像蜘蛛網狀的裂紋。這類裂紋的寬度和深度特別小，裂紋沒有完全裂透的，只是抹灰層的表面出現。

　　The so-called shrinkage cracks on the surface of the plaster layer refer to some irregular spider like cracks that appear on the plaster surface of the wall. The width and depth of these cracks are particularly small, and the cracks have not completely penetrated, only appearing on the surface of the plaster layer.

　　原因分析

　　Root cause analysis

　　①抹灰層表面出現很多不規則裂縫，最常見的一個原因就是，墻體抹灰的基層含水率過低，也就是基層太干燥。正常情況下，應該在抹灰之前的墻體澆水濕潤。

　?、?There are many irregular cracks on the surface of the plaster layer, and the most common reason is that the moisture content of the base layer of the wall plaster is too low, that is, the base layer is too dry. Normally, the wall should be moistened with water before plastering.

　?、趬w的抹灰有或沒有及時的灑水養護。抹灰層一般都是很薄的，所以里面的水泥砂漿的水分很容易丟失。因此要求抹灰完成以后必須使用灑水的機器的對表面噴水，保持去濕潤，養護的時間不能少于一周。

　?、?The plastering of the wall has or has not been timely watered for maintenance. The plaster layer is usually very thin, so the moisture in the cement mortar inside is easily lost. Therefore, it is required to use a watering machine to spray water on the surface after plastering is completed, to keep it moist, and the curing time should not be less than one week.

　　處理方法

　?、倏梢圆扇≡谀ɑ覍拥谋砻鎾觳＠w網進行修復。對于裂縫的部位直接掛一層玻纖網，然后使用抹面膠漿之類的材料進行修復。

　?、?Fiberglass mesh can be hung on the surface of the plaster layer for repair. Hang a layer of fiberglass mesh directly on the crack area, and then use materials such as plaster to repair it.

　　②還可以采取在拼膩子的時候掛網來防止開裂。因為這時抹灰層的開裂并不嚴重，所以只要做好了防止膩子開裂的措施就可以了。

　?、?You can also hang a net when applying putty to prevent cracking. Because the cracking of the plaster layer is not severe at this time, as long as measures are taken to prevent cracking of the putty, it is sufficient.
