As to why there is a crack, there are many reasons for this.
Cracks on the surface of the wall caused by cracking of the wall paint are mainly caused by poor quality of the wall paint products and improper operation during the construction of the wall paint.

3, wall "fancy" cracking plaster layer cracksCracks on the plastering layer of the wall are divided into normal cracking and abnormal cracking. Normal cracking mainly refers to cracks in the plaster layer caused by shortening of the cement mortar. Irregular cracking is mainly due to cracks due to information or improper construction process. Normal cracking is difficult to prevent, but abnormal cracking conditions can be avoided. If there is a large area of ​​hollowing in the plastering layer, the original plastering layer should be knocked out, and the plastering layer of the cement mortar should be re-doed. After the leveling, the paint should be painted according to the normal procedure. However, after such treatment, the cost will increase relatively. If there is only a small area of ​​cracking, there is no turning, emptying, falling off, you can fill the wall really good cloth, and then brush the paint according to the normal process.

Gypsum board, prefabricated partition board and prefabricated floor board will be shortened and change in orientation, resulting in cracks in joints, usually vertical seams or horizontal seams. It is recommended to wait for the entire building to stabilize after the deformation has stabilized, and the repair within a short time is prone to be repeated.
5, wall "fancy" cracking putty cracksThe wall scraping putty can make the wall surface more lubricated and delicate, and the flatness is much higher than the cement wall surface, so that the paint on the wall surface works better, and at the same time, the paint is saved. If cracks occur in the putty layer, it will simply cause the surface to crack. Therefore, care must be taken to prevent cracking of the putty layer during construction. If the crack has penetrated into the putty layer, you can first use a sharp tool to enlarge the crack to a screwdriver size, then fill in the caulking plaster and polish and level it, put it on a grid cloth or kraft paper, put it in a leveling with a putty, and finally follow the normal procedure.
