What should I do if there is a crack in the wall? What should I do if there is a crack in the wall?

There are many reasons for cracks on the wall, such as: flaws in the construction of the house, including the mortar mix ratio is not enough when the mortar is leveled, or the cement mortar is not dried thoroughly and the ash is batched, which will cause the cement mortar to crack after drying. It will cause latex paint cracks after the decoration is completed, and the other is that the decoration workers in the construction in order to shorten the construction time, the bottom is not completely dry when the bottom layer is polished, which will also cause this phenomenon.

Generally, it can be solved according to the specific situation: 1. Cracks in a straight line from the inside to the outside. This is the reason for the settlement of the building itself.

For example, a new home will have a sinking foundation within a year or two of the first occupancy, and then gradually enter a period of stabilization. In the process of settlement, the wall will have horizontal or oblique cracks due to uneven settlement. Do not take any measures against the base layer during the settlement process, and wait for the settlement to gradually stabilize before dealing with the cracks.

Treatment: Shovel off the cracked wall of the base layer - paste anti-crack bandage - batch putty - brush latex paint. 2. Local obvious cracks or even cracks.

This kind of crack can be scraped off with a shovel blade after the heating is over, and then putty and latex paint are brushed. However, there will be a global and partial color difference. It is recommended to leave the latex paint left over from the previous decoration, and when repairing again, using the original latex paint can effectively reduce the color difference.

3. Very subtle shallow cracks. This kind of crack is related to the wall being too dry in winter, do not rush to repair it after the end of heating, generally after the relatively humid climate in spring, the crack can heal on its own.

If there are cracks in the wall, special treatment must be carried out, otherwise even if the putty is scraped, it will crack again in the future: shovel each crack into a V-shape (V-shaped means that the section of this groove is V-shaped, if the crack is small, the V-shaped is 30 degrees, if the crack is large, the V-shaped 45 degrees), blow the floating soil clean, fill the V-shaped crack with real 903 glued gypsum powder, seal it with kraft paper tape after drying, and then scrape the putty.

Similarly, for the places that have been grooved in the wall in the hydropower renovation, they should also be sealed with plaster, pasted with kraft paper, and then scraped putty.

This wall should be cold or cool or with hollow bricks to crack the occurrence, harmless, when the beginning of the decoration masking paper and net hanging glue did not carefully deal with it, perhaps only scrape off the wall skin and do it again.

1. You can use pressure grouting, which is very simple, as long as the adhesive is put into the air compression excitation machine, and then fill the gaps on the wall, so that the cracks on the wall can be effectively repaired. 2. Or knock open the original cracks on the wall, and then use elastic putty to repair them. 3. If the crack is relatively large, you can also directly remove the cement on the outer layer of the wall, and then install a layer of gypsum on the outside, and evenly apply latex paint, so when decorating the house, you must buy good materials and choose a good supervisor, so as to ensure the quality.

Reasons for this:

1. It may be because the quality of the wall itself is not very good, because the developer is not in place during construction, and the material selection is not good enough, and the construction process is not careful enough, which can be said to be the main reason.

2. It is also possible that this house is an old house, so the foundation is not very firm, resulting in instability, or when decorating lamps and lanterns at home, too many chandeliers are chosen, because the chandeliers are sagging, so the stability is not good enough, and the wall will be deformed for a long time.

3. Or when decorating the house, the materials used in the wall are not very good, and inferior products lead to failures. Ming teasing.

1. First of all, find a putty knife, if you don't have it, you can replace it with a thin iron plate, putty, buy paint with the same color as the wall, and a piece of sandpaper about 500 mesh;

2. Use the putty cavity to scrape off the paint on the upper edge of the crack, scrape it flat all around, pay attention to the control area, don't scrape too wide, scrape off the crack, and then use the adjusted putty powder to fill the crack. To scrape flat with a putty knife;

3. After filling the putty for about an hour, after the putty is dry, the hand feels a little hard, so use sandpaper to polish the putty smoothly;

4. Then use the adjusted paint to paint the wall, and paint a little from top to bottom;

5. Since it is a partial rework, it is recommended to spread newspapers on the ground to avoid dust and paint everywhere. After brushing the paint, I feel that the round rock is very smooth and do not touch it, because the Zhengyu paint will be leveled automatically.

Most of the wall cracks are caused by cracks in the cement of the wall, or cracks in the joints of the wall "insulation board", or cracks at the lap of the old and new walls, or cracks at the junction between the trunking and the original wall after the plumber slots, most of which are not the quality problems of decoration, but the insurmountable defects in the building. The solutions are:

1. If there are cracks in a large area, the bottom of the wall base bucket at the crack should be chiseled into a "U" shape, and the spacing of the "U" groove should be greater than 20cm, and the chiseled base should be chiseled, and then the steel wire mesh should be hung.

2. After the wall substrate is cleaned, a layer of good cloth, kraft paper or newspaper is pasted on the wall, and the tension of the fiber is used to ensure the integrity of the latex paint film.

3. Remove the insulation board on the surface of the wall, or remove the cement wall, install a layer of gypsum board or "five-centimeter board" 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 sides of the plate, which is easier to deal with.

4. Adopt decorative materials with elasticity. There is a kind of "elastic putty" that can compensate for the problem of cracks in the wall to a certain extent. A certain wall paint can also play a role in covering small cracks in the wall.

The cracks on the wall generally have temperature cracks, settlement cracks, and structural cracks, and different crack structures have different solutions.

1. Temperature cracks: The common cracks in the house cavity have little impact on the structural safety of the house, because they will only affect the appearance of the house and will not affect the safety of the house. Remedy:

In the cracked places, we can paste non-woven fabric, paste PVC mesh cloth or sew it with mortar, and then apply paint.

2. Settlement cracks: Settlement occurs slowly, and after settlement cracks occur, we should repair the cracks after they are stabilized. The base for new homes will gradually stabilize over a period of 2 to 5 years.

After the crack is repaired, the wall may still crack due to the sinking of the base, so you don't have to worry too much. If the crack has little to no effect on the overall aesthetics of the house, it can be repaired after a long time. Repair usually pastes it with cement mortar, putty or cement elastic putty, plaster filling and caulking tape.

3. Structural cracks: Hu draft's ordinary decoration methods cannot be repaired, and there is no way to repair them, at this time, we should find professional building structure personnel to repair it according to the specific situation, and adopt some good measures.

This answer applies to the treatment of cracks in 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.

How to deal with cracks in the wall?

1. 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.

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.

Treatment suggestion: First of all, you can directly use latex paint to repair. The specific method is to brush the latex paint once in the cracked position without shoveling.

At this time, although there is a color difference, it can be repaired. In addition, you can also paste some decorative paintings or hang some decorative paintings to cover up.

Another measure that can be taken is to eradicate and rebuild. At this time, the cracked surface of the latex paint layer is gently shoveled off. Of course, it is necessary to paste masking paper around the area in advance to avoid damage to the area.

Then you can repaint the latex paint, which can also be repaired.

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.
