First, the problems of workers, such as small problems such as not handling the big white material well (this is rare).

Second, when some houses are built, the walls are made into doors to facilitate the construction of the building, and then the door is blocked when the building is completed (that is, the wall of your house is blocked). In this case, the professional white workers will use caulking tape to embed the gaps around the original blocked door before construction, and then hang the big white, so that there is no problem.

What's the matter with cracks on the wall? What is the solution?

Putty scraping the wall can make the wall look softer and more delicate, that is, beautify and save materials. However, if the frankincense layer breaks, it is easy to cause the surface layer of the hand stall to break.

**Method: If the crack has penetrated into the layer of cement, you can also first use a sharp tool to enlarge the size of the crack with a screwdriver, rivet and polish the plaster, use mesh fabric or kraft paper and then align the greasy bridge mess level.

Mainly due to the quality of wall paint products and the wrong operation in the construction process of wall paint. If the temperature is too low, the film-forming temperature of the wall coating cannot be reached, and a continuous coating film cannot be formed, which will also cause the paint on the wall to crack.

Treatment: If it is only a crack in the surface paint film, you can use fine sandpaper to polish the crack, and you can choose the same color wall paint as you can repaint. In addition, many consumers have made every effort to choose a good painting when they buy paint, especially when they see a carton that says "crack resistant" on it, thinking that using this paint can prevent the wall from cracking the product.

Gypsum cracks are divided into normal cracks and abnormal cracks. Normal cracks mainly refer to cracks in the plaster layer caused by the shrinkage of cement mortar. Abnormal cracks are mainly caused by insufficient materials or construction techniques. Normal cracking is difficult to avoid, but abnormal cracking can be avoided.

**Method: If vacuum cast in a large area in the plaster layer, the layer of the original plaster must be removed and the plaster layer of the cement mortar must be reworked, then leveled and painted according to the normal process.

The crackage of the seal is mainly caused by the joint between the wall cutting reinforced concrete and brick ceramite, the reinforced concrete beam and the ceramsite brick door compartment, separating the plasterboard between the macroscopic joint and the original wall panel. Cracks in the office board are mainly due to the surrounding environment or external forces. Drywall, prefabricated partitions and prefabricated floor slabs will shrink and change position, which will result in joint cracks, usually vertical or horizontal.

Solution: It is recommended to repair the entire building after the deformation has stabilized, and the repair can be repeated in a short time.
