If there are cracks in the wall, what are the ways to repair and renovate them?

Normal cracking cannot be prevented, and abnormal cracking should be avoided. When the hollow drum area of the plastering layer is too large, the plastering layer needs to be knocked off again, and then brushed after leveling, and the repair is higher; If it is a small area of cracking, there is no hollowing, falling off and other problems, you can paste the polyester cloth on the wall and then spray paint.

<> there are cracks in the putty layer, cracks will also appear in the wall, which is mainly caused by improper treatment in construction, once the cracks enter the putty layer, the cracks need to expand, then fill the caulking plaster and polish, and then use grid cloth or kraft paper to level with putty, and finally finish the repair with paint or wallpaper. Cracks in the structural layer of the wall are due to cracks in the structural layer of the wall itself, or cracks in the wall itself, and then the appropriate treatment method is not taken in the decoration.

Cracks at the bottom of wall joints can also lead to surface cracks, which mainly occur in reinforced concrete shear walls and ceramsite brick joints, gypsumboard partition walls and original wall joints, behind sealing doors, reinforced concrete beams and ceramsite brick joints. Treatment method of cracks in the wall of the insulation board: cut the cracks with a putty knife and fill the plaster as deep as possible.

Be sure to fill it evenly. Then use a bandage, watercress cloth or white dakara cloth to paste the cracks, and then blow putty or do other processes after drying. If the crack is more severe, it may be better to patch the seam with kraft paper or newspaper.

You should shave often, shaving thinner each time and at longer intervals. But pay attention to the number of times you scrape putty, and it is easy to fall off.

Can't see clearly. Look at what I posted above.

No matter how good the decoration of the house is, once you live for more than ten years, it is inevitable that there will be some phenomena that we do not want to see. I believe that there should be many owners who encounter cracks on the vertical and missing surfaces of the house walls, but for many people, they do not know how to repair the cracks in the walls? What do you need to pay attention to when repairing?

1. How to repair wall cracks.

First of all, the paint film of the first cracked part of the fiber should be removed, and then the cracks should be filled with elastic putty. However, when carrying out construction, it is necessary to treat the base layer with a primer. However, it is necessary to avoid operating at high temperatures and low humidity, which can easily affect the effect, and the paint film should not be too thick when applying.

Secondly, if the crack area of the wall is too large, the crack of the wall base can also be chiseled into a "U" shape, the spacing should be greater than 20 cm, and the chiseled base is chiseled, and then the steel wire mesh is hung on it. Then use elastic decorative paint to repair the cracks.

2. Precautions for repairing wall cracks.

a. How to repair wall cracks? In fact, you should find out the cause before fixing it. Because the cause of wall cracking is different, the treatment method is also a little different.

Only by finding the real cause can we remedy it in a targeted manner, rather than just patching it up.

b. Most of the reasons for cracks in the wall are caused by the weather, but it is not so easy to deal with. However, if you want to stop water and rain, you need to do a good job of defense. There are many high-quality waterproof coatings on the market, and you can buy some and use them to prevent their outflow for a long time.

c. In addition, it should be noted that if the base is not firm, the base of the wall must be removed, and then the base layer is re-processed, so that it can be foolproof and will not affect the future residence. Of course, after the construction is completed, attention should also be paid to the maintenance of the wall, especially to avoid rain or exposure.

A variety of different crack treatments:

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 the surface of latex paint and cracks in the wallpaper: 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.
