There are cracks in the walls of the new house, and the acceptance has been completed at this time,

This cannot be done in the fall, otherwise it will shrink and deform. In autumn, keep windows and doors closed for 1 to 2 days after painting, or ventilate only in the morning and evening to allow the walls to dry.

If there are cracks now, it is best to wait until the spring, otherwise, the wet weather will affect the remedial effect, and the cracks will still come to the door when the weather is warmer.

It is understood that in addition to the easy cracks at the junction of different materials, cracks may also appear on the wall. "When the painter is constructing, if the putty is not dry and the wall paint is brushed, it is easy to crack, and the imbalance of water and oil ratio of the wall paint may cause the wall to crack.

Due to the different shrinkage rates of different materials, cracks are most likely to appear at the junction of different materials. Cracks between wood boards and cement walls and gypsum boards and cement walls are particularly common, such as window covers, door covers, ceilings, etc., which are the most prone to cracks.

The principle of charging is that whoever entrusts and who charges. In general, the purchase contract already stipulates the obligation of the developer to provide the buyer with the area measurement data, so this cost should be borne by the developer.

Land use rights refer to the rights of units or individuals to occupy, use, benefit from and dispose of state-owned land or collective land in accordance with law or agreement. China's "Urban Real Estate Management Law" clearly stipulates that the purchase and sale of real estate refers to the simultaneous transfer of the ownership of the house and the land use right within the scope occupied by the house. In other words, during the term of the land use right, the property owner has full ownership of the property and the land use right.

According to China's relevant land laws, the land use right has a certain period, but it does not mean that the property right of the house will also expire after the land use right expires. Real estate transfer refers to the acquisition of real estate through transfer, sale, gift, inheritance and other means, and go to the housing ownership registration center to go through the procedures for changing the property rights, that is, the whole process of transferring property rights from Party A to Party B.

Cracks are most likely to occur where different materials meet.

If there are only some cracks on the surface, and only some small cracks, you can simply repair them, for example, the common practice is to lay film materials along the surface of concrete cracks, and epoxy resin or resin can be used to impregnate glass clothThis restores the surface aesthetics of the component and improves the durability of the wall.

If the crack is wide, it can be chiseled into a V-shaped or U-shaped groove along the surface of the cracked concrete, and the resin mortar material can be used to fill it, and materials such as cement mortar or asphalt can also be used.

If the seam on the surface is small but deep, the injection tube can be set up in the crack first, and the other parts can be sealed by surface treatment, and the material can be injected with low-viscosity epoxy resin, and the electric pump or hand pump can be injected to repair. If the crack affects the safety of the structure, the structure should be reinforced.

The cause of cracks in the walls of new houses

Generally speaking, there will be no cracks in the walls of the newly built house, but this does not rule out some improper operations during construction. However, it cannot be said with certainty that cracks in the walls of new houses are abnormal, but should be analyzed according to the actual situation. This may be formed during the construction of the project, or it may be caused by improper maintenance in the future.

For the wall cracks that have appeared, it is necessary to observe the shape and direction of the cracks, whether there is a development trend, analyze the causes of the cracks, determine the nature of the cracks, and judge whether the cracks have an impact on the safety of the house structure. If it does not affect safety, it can be dealt with simply. If the impact is large, appropriate technical means should be taken to reinforce the treatment.

If there is really no repair value, it should be demolished as soon as possible.

1. Temperature cracks - the most common house cracks, which have little impact on the safety of the house structure, this kind of crack only affects the indoor appearance of the house, and will not affect the safety of the house.

2. Settlement cracks - when the settlement development is slow and there is a weakening trend after the occurrence of settlement cracks, the cracks should be repaired after the cracks are stabilized. It takes 2-5 years for the foundation of a new house to stabilize and you don't have to worry too much about the possibility that the walls will crack due to the subsidence of the foundation after the cracks are repaired. If the crack has little impact on the overall aesthetics of the house, it can be repaired after the first repair.

The repair is generally filled with cement mortar, polymer mortar or elastic putty and gypsum, and the caulking tape is pasted.

3. Structural cracks - ordinary decoration methods cannot be repaired, and professional building structure personnel must be found to take corresponding measures according to the actual situation.

4. Cracks in latex paint on the surface Wallpaper cracks: If it is only a crack in the surface paint film, use fine sandpaper to polish the crack off and repaint it. If the wallpaper is cracked at the joint, moisten it with warm water and re-apply the wallpaper glue to paste.

5. Putty screed cracks: If the cracks have 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 grid cloth or kraft paper and then use putty for leveling, and finally paint or paste wallpaper according to the normal process.

6. Cracks in the plastering layer of cement mortar: 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 or wallpaper should be painted or pasted according to the normal process after leveling. However, the cost will be relatively higher after this treatment, and the owner can choose the repair method according to his own economic ability.

If there is only a large area of cracking, there is no sand, hollowing, or falling off, you can paste a good cloth all over the wall, and then paint or paste wallpaper according to the normal process. The relatively low cost is to nail a layer of gypsum board directly on the original wall, which requires environmentally friendly milky white rubber and steel nails to be used at the same time.

7. Cracks at joints: It is recommended to repair the whole building after the deformation tends to be stable, and the repair within a short period of time is prone to recurrence.

If you don't care about the developer, you can find the housing authority, which belongs to the three-guarantee period.

When the house is handed over, it is undoubtedly the happiest time for buyers, so this means that they will have a house of their own, but every year there will be some flaws in the delivery of the new house, such as water seepage on the ground of some buildings, so if there are cracks in the walls of the house after delivery, what should I do at this time?

First of all, it depends on how serious the crack is, if the damage to the wall is relatively large, it may involve safety issues, and according to the provisions of the sales contract signed between the buyer and the real estate developer, the developer should deliver the qualified house to the buyer, if there is a quality problem in the house during the acceptance process, then the buyer can ask the developer to terminate the contract, and ask for compensation for damages, if the wall of the house is cracked, Even if the developer has delivered the house to the buyer for use, but the quality of the main structure of the house is unqualified, the buyer naturally has the right to request the developer to terminate the contract and require it to compensate for losses.

Secondly, if the cracks in the walls of the house will not be so serious, then you can let the developer arrange personnel to repair, in fact, the cracks in the walls of the house may also be because of the gaps in the plastering layer, but this will not affect the main structure of the house, so if there are cracks in the plastering layer, then you only need to remove the plastering layer and then re-plaster to improve the situation, if it will not affect the main structure, then it can be repaired. The work on these restorations is still largely undertaken by the developers themselves.

Finally, in fact, if there are cracks in the walls of the house, as long as it does not affect the main structure of the house, as long as the developer arranges personnel to rework, most of them are not major problems, but if it involves the safety of the main structure, then the buyer has the right to terminate the contract with the developer, and at the same time require the developer to compensate.

You can negotiate with the property, and then you can negotiate with the developer to have the developer repair it, which is not a big problem.

You can find the property, let the developer of the property negotiate, or you can apply for compensation, which can be repaired in a timely manner.

At this time, you should communicate with the developer, and you should also call the local consumer association, the local housing management department and the regulatory bureau.

First of all, it is necessary to determine whether the crack is a structural crack or a crack in the plastering protective layer.

Cracks in the plastering protective layer do not affect the use of the house, you only need to contact the property or developer to repair it, if the ground is tiled, it will not be repaired and will not affect the tiling.

If it is a structural crack, it is necessary to contact the developer, and the developer will repair it and the quality inspection department will issue an inspection report that does not affect the quality of the house. If the standard of use is still not met after repairs, the property should be checked out and the developer will compensate the buyer for the corresponding losses.

Determine the cause of cracks on the wall.

One: subtle shallow cracks;

Causes: 1. The wall contains moisture during the painting process, and 2. Cracks are caused by changes in temperature and humidity.

Solution: Wait for automatic recovery. Paste wallpaper on the wall.

2. Deep cracks or original cracks appear again after repair.

Reason: Due to the small size of the wall, there are cracks that cause putty to appear after repair.

processing methods; Now it is useless to simply repair the putty. It is necessary to scrape off the putty on the cracks, use cement mortar or resin mortar to repair the cracks on the wall, and then repaint with putty after the wall is dry and solidified.

Three: local cracks.

Reason: uneven subsidence of the foundation and stretching the wall.

Treatment: Check whether the wall is stable, if it is stable and not sinking, use gypsum powder to repair it. If the crack is still expanding, then use cement grout to close the crack and then repair it with gypsum powder.

Four: large-scale cracks or cracks.

Reason: The foundation is unstable, and the treatment method is to pick up the heavy cover.
