What should I do if there are cracks in the wall? What to do about cracks in the wall

The wall cracks caused by the cracking of the structural layer of the wall itself generally include two conditions, the first is that the original wall itself has cracks, and no appropriate treatment methods are taken in the later decoration process; The second is that the original wall has no cracks during decoration, but cracks occur in the later stage due to uneven foundation settlement and large temperature changes.

Cracks in the wall of the house are mainly due to the handover of different materials, and if the external temperature changes are relatively different, the temperature deformation between the floor and the masonry is not coordinated, which will lead to cracks.

The cracking of the putty layer is generally due to the improper ratio of the putty layer, uneven application, or too thick or too thin, and the strength of the wall is different, which leads to the cracking of the wall. Or the putty is painted before it is completely dry, and air accumulates in the wall, causing cracking.

In the crack of the wall, the base layer of the wall is cleaned, and a layer of good cloth, kraft paper or newspaper is pasted on the wall, and then putty is applied and latex paint is brushed. This method is to use the tension of the fiber to ensure the integrity of the paint film of the latex paint, and the method is relatively simple and easy.

If there are cracks in a large area of the wall, the crack will be excavated at the bottom of the wall to expand, and the spacing of the grooves is greater than 20cm, and the chiseled base is chiseled, and then the steel wire mesh is hung, and then the cracks are painted with elastic decorative materials to make up for the cracks in the wall.

Smaller cracks can be patched with caulking paste and seam paper tape. Cracks caused by the settlement of the building structure, as well as large cracks caused by tensile force and dry shrinkage, need to remove the putty layer on the wall and repair and strengthen it with steel wire mesh and high-strength nylon mesh cloth.

If the wall cracks are caused by foundation settlement, it is more difficult to deal with, in this case, the base layer can only be removed, the wall cracks are cleaned out, and then the epoxy resin injection is filled into the gaps until the gaps are filled. Hang steel wire mesh on the surface of the gap, and then powder cement mortar for reinforcement treatment. After doing the previous work, you can scrape the putty to make the wall paint.

The cracks on the wall don't really have much to do with it, you can take the latex paint and make it up, if the cracks continue to increase, then you have to consider shoveling the wall again to fill the putty, and then re-paint.

Cracks in the wall should be repaired by property personnel. Because the crack in the wall is a wall quality problem, you should find the property department to be responsible for repair.

What kind of cracks do you have to see on the wall, is it the rain that soaks the wall paint and cracks? Or does it cause the wall paint to crack? Or is it a crack in the structural layer of the wall?

The first two are easy to do, just find someone to fix it, and of course you can make it up yourself, but it may not be so good-looking. In the third case, you must find someone to evaluate and deal with it, because the house itself may have safety hazards.

The walls of my house are latex painted, so there are many latex paint cracks, and when the maintenance master comes to deal with it, he scrapes off the garbage on it, and then re-does it again, and the overall look is not bad.

Decorating the wall seems simple, in fact, there are still a lot of texts in it, especially the family that started work at the beginning of the year, basically entered the stage of painting the wall, due to the high temperature and rainy weather, the wall often has cracks, so, what to do with the cracks in the wall?

Method 1: If there are cracks in a large area, chisel the bottom of the wall at the crack into a "U" shape, and the spacing of the "U" groove is greater than 20cm, and the chiseled base is chiseled, and then the steel wire mesh is hung. Then the cracks are painted with elastic canopy decoration materials to make up for the cracks in the walls.

Method 2: Remove the insulation board on the surface of the wall, or remove the cement wall, install a layer of gypsum board or "five-centiboard" outside the insulation layer, and then make latex paint on it. This method can remove all the irregular cracks, and the cracks are generally the joints between the plates, which are easier to deal with.

However, this method is expensive and difficult to construct.

Method 3: Shovel off the cracked paint film and fill the cracks with elastic putty; Use elastic wall paint for construction, and use primer for the base layer with strong water absorption; Avoid construction under the condition of high temperature and low humidity; The paint film should not be too thick when applying. When spraying, be careful to avoid excessive atomization.

Precautions for wall decoration.

Pay attention to the inspection of the material.

There are many materials used in wall decoration, so be sure to check the materials used in wall decoration. First of all, it is necessary to pay attention to whether the foreman has stolen beams and changed columns, or whether the materials provided by the company are included in the situation. Then it is necessary to pay attention to the fact that every time the wall materials enter the site, the corresponding decoration materials can be signed and accepted only after confirming them, so as to avoid unqualified decoration materials being mixed into the construction site.

In addition, the occurrence of secondary construction should be avoided as much as possible during the construction process, which can also play a role in saving decoration costs.

Pay attention to the construction process.

Because the wall needs to be grooved to do the pre-embedding work of wires, we must pay attention to the process of construction. When the transformation increases the water pipe wire, the slotting on the wall can not be thrown horizontally, it should be thrown vertically, because the damage to the wall is great, the seismic resistance, the strength is very damaged, only the vertical throw, the length of the horizontal throw can not exceed 3-5 cm, if the groove is deeper, it is easy to touch the steel bar in the wall, and the steel bar sawing is easy to lead to the overall wall safety, on the contrary, if the groove is shallow, it is easy to occur the phenomenon of wall bulging. The reason for the appearance of wall cracks is very simple, it is not impossible to avoid wall cracks, and we need to check well when building the wall and choose a reliable construction unit.

If there are cracks in your home, don't be too anxious, in addition to the above three methods, you can also find a master who specializes in repairing the wall.

Cracks in the wall are a common problem, and the general treatment methods are as follows:

1.Treatment of small cracks: If the cracks are small, they can be closed with a seam sealer. First, the crack is cleaned first, then filled with a seam sealer, then scraped with a scraper, and then sanded with sandpaper after it dries.

2.Treatment of large cracks: If the cracks are large, you need to use a small hammer to knock the ridge mold rough to prevent the bricks from loosening, and then use a cleaning brush to remove the dust in the cracks. Then fill it with caulk, scrape the caulk flat, and then sand it carefully with sandpaper.

3.Strengthen the wall support: If the crack is caused by the wall becoming shakura-shaped, the wall support needs to be strengthened.

Methods include piling, drilling and reinforcement, wall reinforcement, etc., which need to be handled by professionals. Either way, it should be done according to the actual situation to avoid bigger problems. At the same time, maintaining the wall in daily life, such as uniform cleaning and ventilation, can reduce the possibility of cracks in the wall.

There are many reasons for wall cracking, some cracks are just problems with the putty layer of decoration, and some cracks are serious problems such as cracking of the building foundation wall, and the methods and measures to deal with them are very different. The developer's responsibility is to seek compensation from the developer.

The shelf life of the new house of the commercial house is generally two years, therefore, for the cracking of the foundation wall of the house that is not more than two years old, as long as it is not caused by human factors, the developer should be found to solve the problem, 1, now most of the new houses are frame or frame structure, the wall is the filling wall made later, and the cracks can not be seen when the house is delivered, and the cracks will appear after a long time due to the shrinkage of different materials. The transverse direction is mostly at the junction of the beam and the wall, and the vertical direction is mostly at the shear wall. Of course, it should be the developer's responsibility to correct this, because this is because the anti-crack net was not affixed at the junction of different materials during civil construction.

Many owners have the same problem, which is more telling the problem, and it is more powerful if everyone jointly finds the developer or relies on the owners' committee. In fact, it is not difficult to correct, and it is enough to make anti-crack nets during decoration. You can ask the developer to compensate, and the cost is used for decoration, which is convenient for everyone.

2. If the indoor wall is only cracked by the indoor putty layer, there are two possible reasons, one is that there is a problem with the putty material, and the other is that there is a problem with the decoration construction process and process. In the case of contracting labor and materials to the decoration construction party, during the warranty period, the construction party will be directly repaired and claimed. Outside the warranty period, if the crack is not serious, find someone to smash the putty layer around the crack to repair it; In case of severe cracking of large areas, it is recommended to scrape all the putty layers directly and then redecorate them again.

Wall cracks are a common problem caused by changes in the internal or external environment of a building. If these cracks are not dealt with in a timely manner, they will continue to grow, which can lead to structural damage and insecurity. Here are the main causes of wall cracks and how to deal with them.

Reasons:1Poor foundation: If the wall is built on an unstable or uneven foundation, it is prone to cracks. This can also be due to the subsidence of the foundation or the ** in the area.

2.Material issues: If building materials such as bricks, stones, or cement are not up to standard or of poor quality, they can create cracks during use.

3.Softening and shrinking: In some cases, concrete may soften and shrink, resulting in cracks. This can be due to overuse of water, accelerators, or casts, among other things.

4.Temperature and humidity changes: Walls are subjected to seasonal temperature and humidity changes, causing rapid expansion and contraction, which can lead to cracks in the wall.

Coping methods:1Observe the cracks:

The nature and location of the cracks need to be observed first to determine their severity and health. If the cracks are small and shallow, they can be repaired by filling, while if the cracks are very deep or continue to expand, they need to be thoroughly repaired and reinforced.

2.Repair cracks: Wall cracks can be filled by using a mixture of mortar adhesive and sand. When repairing cracks, prepare mortar and some tools such as shovels and brushes. The mortar is then gradually added to the cracks and leveled under pressure using a brush or shovel.

3.Repaint: Paint can repair cracks and have an aesthetically pleasing appearance. Before repainting, sandpaper or equip the wall with process tools to remove uneven surfaces.

4.Reinforcement of walls: If the cracks continue to grow, reinforcement materials may be required. This repair required shutting off electricity, new wall construction materials, and tools to fill in the cracks and cover the surface.

In short, if you find a crack in the wall, don't let it go, you should take the necessary measures, such as observation, repair and reinforcement, so that you can avoid the crack from getting worse and ensure the safety and stability of the house.

Causes and treatment of wall cracks.

1. Cracking of the paint layer.

The cracks on the wall surface caused by the cracking of the wall paint layer are mainly caused by the poor quality of the wall paint products and the improper operation in the construction process of the wall paint.

The temperature is too low to reach the film-forming temperature of the wall paint and cannot form a continuous coating film, resulting in cracking of the wall paint.

Treatment: If it is only a crack on the surface of the paint film, use fine sandpaper to polish the crack off, choose the same color wall paint, and repaint it.

2. Cracking of the putty layer.

Wall scraping putty can make the wall more smooth and delicate, and the flatness is much higher than that of the cement wall, so that the wall painting effect is better, and it also saves paint. If the putty layer cracks, it is also easy to cause cracking in the surface layer. Therefore, it is necessary to pay attention to avoid cracks in the putty layer during construction.

Treatment: If the crack has penetrated deep into the putty layer, you can first use a sharp tool to expand the crack to a cone size, fill in the caulking plaster and polish and level, paste the mesh cloth or kraft paper and then use putty for leveling, and finally paint or paste wallpaper according to the normal process.

3. The plastering layer is cracked.

The cracks of the wall plastering layer are divided into two types: normal cracking and abnormal cracking, and normal cracking mainly refers to the cracks in the plastering layer caused by the shrinkage of cement mortar; Abnormal cracking is mainly caused by improper materials or construction technology. Normal cracking is difficult to avoid, but abnormal cracking can be avoided.

Treatment method: If there is a large area of hollowing in the plastering layer, the original plastering layer should be knocked out, the plastering layer of cement mortar should be redone, and then painted according to the normal process after leveling. However, the cost will be relatively higher after this treatment.

If there is only a small area of cracking, there is no sand turning, hollowing, and falling off, you can paste a good cloth all over the wall, and then paint according to the normal process.

4. Cracking at the joints.

Cracks in the base layer of wall joints can lead to cracks in the surface of the wall. The cracking of the joints mainly occurs at the joints between the reinforced concrete shear wall and the ceramsite bricks, the joints between the reinforced concrete beams and the ceramsite bricks, the doorways of the back blocking, and the joints between the gypsum board partition wall and the original wall. The cracking of the joints is mainly due to the influence of the surrounding environment or external forces, gypsum boards, prefabricated partition panels and prefabricated floor slabs will shrink and change their positions, resulting in cracks at the joints, which are generally vertical joints or horizontal joints.

Solution: It is recommended to wait for the deformation of the whole building to stabilize after the repair, and the repair within a short period of time is prone to recurrence.

5. The structural layer of the wall itself is cracked.

Cracks in the structural layer of the wall itself can also lead to cracks in the surface wall. There are two situations, one is that the original wall itself has cracks, and no appropriate treatment measures have been taken in the later decoration process; Second, the original wall was decorated without cracks, but cracks occurred in the later stage due to uneven foundation settlement and large temperature changes.

Solution: Ordinary decoration methods cannot be repaired, and professional building structure personnel must be found to take corresponding measures according to the actual situation.
