新房一般交房时，都没在盖了没多久，所以墙体的沉降都不太好。这时轻体墙，梁等与承重墙交缝处等随着沉降都会有轻微的裂纹。对于轻体墙，可使用牛皮纸或的确良布进行处理。拐角接缝处可使用条状带孔牛皮纸处理。网格带一般应用于稍大缝隙的处理。

老房的墙面处理有几种情况：

年代稍远的房子，一般都是砖墙或沙灰墙，这种墙极容易有龟裂。因为是砖体有空气流动，谁都无法避免。使用贴布等方法可以延长出现龟裂的时间，但不能保证完全不裂。

近代的房子一般都是砖混或混凝土的房子，发生裂纹的情况就较少了。如是出现的话，可根据实际情况来处理。

最后说一下，选择装修公司时，尤其要注重售后方面。如果-wall-face-appears-such-as-any-of-the-above, all are repairable, as long as you choose a company that is honest and reliable in its after-sales service. They will not cause such problems after the heating season ends.

问题重点是在“all”上. That's why I'll answer you - it's not "all", but rather in areas where there are already cracks or where cracks tend to appear. And in my opinion, these are all remedial measures that address symptoms rather than the root causes of the problem.

The main reasons for cracking include uneven settlement and differences in the thermal expansion rates of different materials. Therefore, cracks usually occur at joints between walls and columns, near doors and windows.

Generally speaking, adding bricks can be prone to cracking... You need to apply them; at interfaces between two different materials... You need to apply them; around pipe slots when painting... You need to apply them.

Not always necessary. The characteristics and functions of auxiliary materials like mesh cloth are as follows:

Characteristics: Lightweight, high strength, heat-resistant, alkali-resistant, waterproof, corrosion-resistant,

anti-cracking stable dimensions.

Functions: Effectively prevent stress from causing shrinkage or external forces leading to cracking on the surface of the applied layer.

Dimensions: 10cm wide mesh cloth is available along with 15cm wide mesh cloth (a friendly reminder: please choose sizes based on your actual needs).

If wall conditions are severe and have been completely removed before re-doing work then no netting is needed because cement works better if there's no fear of it cracking later on - just wait until it dries before applying another layer.

Mesh fabric is generally used locally for things like electric wire channels etc., so yes this article does explain how netting helps avoid further damage by filling gaps left by wires etc., which would otherwise cause more issues over time.
