How to avoid cracks in the walls before and after decorating the house? What s the solution?

Cracking of the wall of decoration and decoration has always been an old problem and a common problem in the engineering building decoration industry. Although it does not harm the application, it is ultimately defectivePerception of hazards. Some cracks are more serious, and even will swell and fall, which has safety risks.

Cracks in the interior decoration of the wall are a common problem in decoration, and it is also an inevitable problem in interior decoration.

Generally, after the end of the interior decoration, it is necessary to carry out repairs once in half a year to a year, mainly because of the cracks caused by the different thermal expansion deformation indices of various materials. Before decoration, inspect and repair the wall to solve the cracks in the bottom layer of the concrete on the wall. The bottom layer of the mixed mortar batch putty with hollow and cracked walls should be removed.

Buy a good interior wall putty powder, add a certain proportion of white glue to the interior wall putty powder, and the white glue selection is good for environmental protection. For the construction hole, fill the joint between the wall and the column and beam, smooth it with caulking gypsum, and open the V groove to repair the glue when necessary.

And paste caulking paper. Paste caulking paper at the joints between the gypsum ceiling and the wall. Generally, in the case of interior decoration for three months to one year, there will be some cracks in the adhesive gypsum lines, the decoration ceiling, and some of the walls.

It is better to ask a painter to carry out the repair, and it is better to complete the repair after a winter and summer, and the reliability of the raw materials is better. The probability of re-cracking in the middle and late stages is lower. Wallpaper can cover up and prevent small cracks, which can cause the wallpaper to wrap, unglue, and even tear.

Wall cracking has mixed mortar bottom cracking, structural cracking, surface decoration design layer (putty powder or wall paint) cracking, these three are all construction quality problems, raw material problems caused, it is necessary to pay attention to the quality of engineering construction during the operation, as far as possible. Maintenance method: chisel the original wall on both sides of the crack, chisel the crack 20 cm wide on each side, and then chisel the crack 1 cm deepFirst fill the void with elastic putty, and then use elastic putty to paste the alkali-resistant mesh cloth, wait for it to dry thoroughly and then change the plaster and scrape it flat.

You can pour adhesive into the wall and then make some repairs to the wall. Later you can use a bandage or a nylon mesh cloth.

I think it should be decorated with better materials. Like dragon rocks or some concrete. Also, be sure to paint twice.

In order to avoid cracking the wall surface of the new house decoration, there are the following points to pay attention to:

1.Choose high-quality wall materials: Choose high-quality wall materials, good raw materials and stable quality, which can effectively reduce the risk of wall cracking.

2.Lay a good foundation for the wall: Before construction, the foundation of the wall should be tamped, smooth and firm to avoid cracking of the wall due to poor foundation.

3.Avoid excessive vibration during decoration: Avoid excessive vibration during the decoration process, such as when using construction tools such as electric hammers and drilling machines, it is necessary to comply with the correct operation methods to reduce excessive vibration.

4.Avoid rapid drying: During the construction process, avoid rapid drying, do not use hot air tools such as hair dryers when wet, and speed up the drying speed of the wall, which can easily lead to wall cracking.

5.Fully consider the temperature difference: the wall of the new house should fully consider the temperature difference factor, especially in the northern region, the temperature difference between winter and summer is huge, to ensure that the wall during the construction process is dry and even.

6.Regular maintenance: The walls of the new house should be maintained in a timely manner to keep them dry and ventilated to avoid excessive humidity or dry environments.

To sum up, when decorating a new house, it is necessary to strictly control the wall construction process, select materials suitable for construction, control the quality in the process of applying the ridge, avoid excessive vibration, and carry out regular maintenance on the wall to avoid cracking and other problems.

<> it is normal for the wall to have cracks on the wall after the new house is renovated. First, it may be the wall cracking caused by the sinking of the foundation of the building. Second, the wall is made of different materials, and the expansion coefficient is not the same, which makes the junction crack.

Third, the ratio of cement is not accurate when plastering, and cracks are easy to occur when the ratio is high. Fourth, the material joints of the new wall and the old wall, ceiling, wire trench filling joints or partitions should not be properly cracked. Fifth, it may be that the putty is scraped too thickly or scraped unevenly, drying and shrinking.

Sixth, the quality of materials for the base layer such as internal insulation walls, cement or gypsum is not good, and there are cracks around the slots and construction holes left by hydropower transformation.

Many families will have cracks in the walls of the house after renovating the new house, and at this time, everyone will consider how to repair it. For those who don't know how to decorate, they don't know how to deal with it, so everyone knowsWhat should I do if there are cracks in the wall after the renovation of the new house?What should I do if there are cracks in the wall after the renovation of the new house?

1. Temperature cracks. Common house cracks, has little impact on the safety of the house structure, this kind of cracks, only affect the interior appearance of the house, will not affect the safety of the house, can be appropriate some remedial measures: paste non-woven fabrics at the cracks, post PVC mesh cloth or plug the joints with mortar, and then repair them with paint.

2. Settlement cracks. When the settlement crack develops slowly and weakens after the occurrence of the settlement crack, the crack should be corrected after the crack is stabilized. It will take 2-5 years for the foundation of a new house to gradually settle, and you don't have to worry too much about it after the cracks are repaired, during which time the walls may still crack due to the subsidence of the foundation.

If the crack has little effect on the overall beauty of the house, it can be repaired after the first repair. Corrections are usually filled with cement mortar, polymer mortar or elastic putty, gypsum, and caulking tape is posted.

3. Structural cracks. Ordinary decoration methods can not be corrected, it is necessary to find professional building structure personnel according to the actual situation, corresponding measures.

4. Cracks in the appearance of latex paint. Wallpaper cracks: If there are only cracks on the surface of the paint film, use fine sandpaper to polish the cracks off and paint them from scratch. If the wallpaper is cracked at the joints, moisten it with warm water and apply the wallpaper glue from the beginning.

5. Putty screed cracks. If the crack has been deepened into the putty layer, you can first use a sharp object 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 then paint or paste wallpaper according to the normal process.

6. Cracks in the plastering layer of cement mortar. If the plastering layer presents a large area of hollow and high potato digging, the original plastering layer should be knocked out, and the plastering layer of cement mortar should be made from scratch, and then painted or wallpaper according to the normal process after leveling. However, the cost will be relatively progressive, 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, 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 method 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 together.

7. Structural cracks caused by wall cracks: This kind of wall cracks are caused by ** or foundation decline. This kind of problem is unavoidable, and it usually takes about 2-5 years for the foundation of a new house to gradually stabilize.

Therefore, it is not recommended to start the decoration immediately after receiving the house, and it is best to wait for the foundation to stabilize for a period of time before decorating.

After the decoration of the wall of the new house is completed, there will be cracks, when encountering such a situation, we need to know how to deal with it, the above is what to do if there are cracks on the wall after the decoration of the new house and the reason why there are cracks on the wall after the decoration of the new house.

Cracks in the wall will not only affect our normal life, but also affect the beauty of the wall, which will greatly reduce the moodWhat should I do if there are cracks in the wall after the renovation of the new house?This? How annoying is that?

1. First of all, you have to look at the crack depth of the layer. Fine cracks usually mean that the paint on the surface has a coating defect.

2. If the surface paint is broken, it may be the cause of the coating, which is caused by the improper mixing of resin and pigment in the paint. After application, the coating continues to react, the coating becomes dry and embrittle, and surface stresses are created.

3. There is also a crocodile pattern, cracked to the second layer of paint, this situation is easy to occur at the bottom, the surface of the paint does not match, and the harder paint will shrink and suspend on the softer paint after coating, and the surface will produce large surface cracks.

4. There is also a kind of crack, the bottom material is cracked. This situation is compounded by many reasons as the coating is affected by factors such as expansion, shrinkage, wetting, and drying. It may be that the surface treatment of the substrate is not carried out well during construction.

It may be that the film thickness of the structure is too thick. It may be that the primer is not drying and a second coat is applied. It's a matter of construction.

1. You can shovel off the partially cracked paint film, and then fill the cracks with elastic putty; Then use elastic wall paint for construction, and the base layer should be treated with excessive water absorption; Do not carry out construction when the temperature is relatively high or the humidity is too low; The paint film should not be too thick when painting.

2. If there is a crack in a large area, the wall surface of the crack surface can be chiseled into a "U" shape. The spacing of the "U" grooves needs to be greater than 20cm, and the well-defined substrate needs to be chiseled and then the wire mesh is suspended. Then, the problem is solved by applying a decorative material with a wide and elastic width to the cracks to compensate for the cracks on the wall surface.
