Fill the crack of the wall, how to make up the crack of the wall

If you do it according to the standard, it should be fine, if it is a calculation problem at the time, it should not only be the top floor, if the wind speed is relatively large, the top floor is definitely not the most stressed floor. Then there are only a few possible scenarios left. Check the main material you use, and see if he has any special requirements, such as how many days can be filled after completion, etc., and if there is cracking, the main body is either structurally faulty or material.

Then ask your workers carefully to see if there is a problem with the wall when filling, if there is any problem when building the main building, if only one floor and one unit are broken, it should be a problem with the construction operation.

The biggest drawback of cement slag bricks is that the expansion coefficient is large, and it is okay when you build the wall, but after a while, when the moisture in the wall runs away, the volume of the brick will shrink, and cracks will appear

The top floor is a floor with a relatively large temperature difference between day and night, plus the wind is strong, the drying is sufficient, and the cracks are a little bigger.

In the plastering process, the steel wire mesh is pasted after the first plastering of the wall, so as to prevent the cracks caused by the water shrinkage of different substrates at the lower mouth of the beam, the shear wall and the brick body.

Summary. Hello, I am very honored to be able to answer this question for you, according to my understanding and professional analysis, the wall cracking can be pasted on the non-woven fabric, PVC mesh cloth, and then modulated concrete to wipe evenly on the top, and then according to what surface of the decorative material putty powder or latex paint you use for the later uniform coating on it.

Dear, hello, the reasons for the cracking of the masonry wall are as follows: 1. Insufficient soaking in water before sticking the wall tiles will lead to cracking. 2. The reserved gap is too small when tiling, which is the phenomenon of thermal expansion and cold contraction of the wall. 3. If the master cuts the tiles improperly, the improper operation of the tile cutting operation will cause hidden cracks and cracks.

4. The cement mortar is unqualified, or the proportion of the cement sofa is incorrect, which will lead to cracking of the tile.

Causes of vertical cracks in the wall:

1. The concrete strength grade is high, the dust delay of the pumped concrete bone bench is small, the slump is large, the water-cement ratio is large, and the amount of cement is also large, and the amount of concrete in this project is very large, which produces a large amount of hydration heat.

2. The wall was dismantled 24 hours after the pouring was completed, and the watering and maintenance were less than 14 days due to the rush period, the schedule, and the watering and maintenance. At that time, it was just in time for the cold air to hit, and the temperature difference between day and night was large. One of the main reasons for cracks is that a large amount of hydration heat is generated after pouring large-volume concrete, and it is not fully cured in the environment with a large temperature difference.

3. Although the wall construction process adopts the segmented layered pouring method, the thickness of the layered pouring is not clear, some are thick and some are thin, and the main links in the construction, such as vibration, etc., are not operated in accordance with the construction and acceptance regulations.

How to repair cracks in the wall.

1.When you notice a crack in the wall of your home, you should fix it as soon as possible. The first step is to chisel the cracked wall first, we first sprinkle water on the wall, wet the wall and then clean it again, so that the chiseling is more labor-saving.

The walls were chiseled to expose the cement mortar wall or putty.

2.After we chisel off the old wall skin, the next step is to apply the interface agent on the wall, and we must pay attention to the uniform application of the interface agent. For the cracks, special treatment should be carried out, you can use kraft paper tape and white latex to stick the cracks to prevent further cracking.

In addition, we also need to level the uneven wall, generally gypsum is more commonly used, the uneven difference is not more than centimeter, and then paste. "Generally, non-load-bearing walls such as lightweight walls and insulation walls need to be patched."

3.After all of the above is processed, everyone is ready to scrape putty. The quality of putty is related to the effect of construction, you can choose putty with higher particle fineness and harder texture, and you can also add a certain amount of white latex to improve the hardness of putty.

4.The last step is to paint the wall, you can put a little more water when you prepare the primer, so that it is easier to paint evenly. When you paint, you should make sure that every part of the wall is painted, so as to ensure the effect of construction.

After the primer is completely dry, you can brush the topcoat, when you brush the topcoat, do not add excessive water, and the drum should not be too short to choose the hair, but it must be fine. The latex paint will dry 4 hours after painting, but do not scrub or touch the wall for 7-10 days.

Causes of cracking of the wall.

There are two main types of wall cracking: settlement cracking and cracking. Settlement cracks are mainly caused by the subsidence of the wall structure, and the cracks are mainly caused by the insufficient strength of mortar or putty, and there are mainly the following reasons for wall cracking:

1. There are cracks in the insulation layer of the original house, which leads to cracking of the wall after decoration;

2. Improper repair and painting after wall slotting, resulting in cracks in wall shrinkage;

3. The ratio of cement is not accurate when plastering, and it is easy to crack if the ratio is high

4. The wall surface is greasy and unevenly scraped.

5. The ratio of latex paint and water is not suitable, and the above non-standard operations will lead to cracking of the wall.

Expand your knowledge: Walls:

The wall mainly includes load-bearing walls and non-load-bearing walls, which mainly play the role of enclosure and separation space. The wall of the wall load-bearing structure building is integrated with the load-bearing and enclosure, and the function of the building wall of the skeleton structure system is to enclose and separate the space. The wall should have sufficient strength and stability, and have the ability of heat preservation, heat insulation, sound insulation, fire prevention and waterproofing.

There are many types of walls, including single-material walls and composite walls. It is an important task of building structure to comprehensively consider the factors such as enclosure, load-bearing, energy saving, and aesthetics, and design a reasonable wall scheme.
