How to repair cracks in the wall is a common problem, but it is also necessary to distinguish the situation before taking measures. Generally, the plastering layer, wall paint layer or wall structure layer is prone to cracks. Cracks in the paint layer are easier to solve, sanded with sandpaper, and then applied with the same color topcoat.

If the crack starts from the plastering layer, it is necessary to first flatten the wall to the surface of the plastering layer, then repaint the cement mortar and then repaint it according to the latex paint process. If there is a crack in the structural layer of the wall, then you need to find a professional to inspect the specific structure of the house. Usually there are large-scale cracks in the home, it is recommended to find a professional team to check and remedy, such as the Nippon Paint Refresh Service team, they will use professional tools to detect wall problems, and then give a specific construction plan.

After signing the contract with the owner, it will come to the construction according to the agreed time, will help move the furniture, do the shelter protection, and after the construction is over, it will not be a walk, it will help to return the furniture to its place, clean up the site, and finally Nippon Paint refresh There is also a set of professional acceptance standards to facilitate the owner's acceptance results. In addition, if you want to take this opportunity to refresh other areas related to the wall, such as curtains, now Nippon Paint Refresh also expands to provide curtain refresh, including basic and upgraded 2 types, which will improve the refreshed home decoration from the three dimensions of fabric, style and texture, so that the living environment is more coordinated, more environmentally friendly, safer and smarter.

First of all, it is necessary to check what kind of crack it is.

If it is a structural crack, focus on checking its danger and convergence.

If the structural crack is still spreading, a professional should be brought to the site to deal with it.

In short, to ensure the safety of the structure and the safety of the people.

Secondly, the construction is carried out on the repair of the cracks after stabilization.

Generally, the cracks are plugged first, and green linen silk can be used to plug them with 1:3 cement mortar on the outside.

Finally, scrape the surface, whiten, and repair according to the surrounding wall decoration.

Buy gypsum powder to plaster the big white wall, and use cement to make up the cement wall.

First of all, to find the cause of the crack, if it is the expansion joint between the structural wall and the brick wall, generally in the maintenance of the base layer all need to be shoveled out of the cracks, and then with epoxy resin injection to fill the gap until the gap is filled and then do follow-up treatment, if the cement stucco layer cracks, generally because the ratio of cement and yellow sand is not right when the wall is powdered, this crack as long as the putty layer is removed to expose the crack of the cement stucco layer, and then directly paste it with carbon fiber anti-crack cloth.

How to deal with cracks in the wall.

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 interior appearance of the house, and will not affect the safety of the house, and some remedial measures can be taken appropriately: paste non-woven fabric, paste PVC mesh cloth or plug the joints with mortar, and then paint and repair them.

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 surface latex paint 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.

If it is a wall that has cracked and fine lines, the cracked wall base and coating should first be treated with joints or joints to ensure the integrity of the matrix. The loose base should be closed with wall reinforcing agent in advance, and then the subsequent application of putty, primer and topcoat should be carried out. At the same time, it is necessary to pay attention to avoid high temperature, humidity and other environments.

Possible causes of wall cracking:

1. There are cracks in the insulation layer of the original house, which leads to cracking of the wall after decoration;

2. Improper repair and painting after the wall is slotted, resulting in cracks in the wall shrinkage;

3. The ratio of cement is inaccurate when plastering, and it is easy to crack if the ratio is high;

4. The situation is that the ratio of wall putty is improper or uneven scraping.

5. The ratio of latex paint and water is not suitable, and the above non-standard operations will lead to cracking of the wall.

Whether in an office building or in the house we live in, we often see cracks in the walls that affect not only the aesthetics of the walls and living room, but also the time the walls are in use. I'll talk about it nextThere are cracks in the walls of the houseand the method of patchingThere are cracks in the walls of the houseCauses.

1. Crack paint.

In some cases, it is more common to crack the paint layer, which is lighter and easier to repair. A crack in the paint layer refers to a crack in the paint layer on the outer surface of the wall. This is mainly due to the poor quality paint used in the decoration or due to the incorrect construction of the painter.

It is relatively easy to repair cracks in the paint. We just need to sandpaper the walls and repaint them with wall paint of the same color.

2. Putty of the crevice layer.

The paint is the shallowest layer of the process, and the lowest layer is the putty layer, and if there are cracks in the putty layer, then we need to repair it in time. Everyone knows that when decorating a wall, the first thing to do is to apply a layer of putty so that it can be protected and decorated. Putty can make the wall softer and more delicate, and it is also easy to paint the back of the swimmer.

Brush cracks in the putty layer are mainly caused by putty being too thick or too thin. When repairing, we need to first use a sharp tool to widen the crack, then immediately fill it with plaster, then sand it and flatten it, put in a layer of kraft paper, and then smooth it with putty powder for painting.

3. Cracks in the plastering layer.

There are cracks in the walls of the houseThis is mainly due to the poor quality of the cement mortar used, and repairing it will be even more problematic. First, we have to remove the surface of the empty wall, then make a new layer of plaster, and then carry out the normal treatment on the wall. Due to the complexity of the restoration, we had to inspect the walls before renovating.

1. Temperature will cause cracks.

There are cracks in the walls of the houseThe reason is that if the temperature between the floor and the masonry is not coordinated, then the masonry will create temperature stress. Masonry itself has the effect of tensile strength. If the temperature exceeds the tensile strength, the wall is prone to cracks.

2. Crack latex paint.

If there are cracks in the latex paint on the outside of the wall, the repair is very simple. You can use sandpaper to grind the cracks and then brush them again with a new latex potato paint.

3. Crack caulking layer.

The reason for the cracks in the putty layer is that the putty brush is too small, and the cracks occur naturally after a long time.

If you want to find a company to repair it during the renovation, then it is definitely not covered by the warranty, and you have to pay for it if you want to repair it, and if you want to find a professional to repair the limb potatoes, then you need to pay a high cost. Is there any way you can fix it yourself?

Today, I will talk about the wall crack treatment methods and some skills, I hope to help you.

1. What is the cause of wall cracks?

1. After the house is built, cracks are left when the insulation layer is decorated, so that cracks will appear on the wall when the interior decoration is carried out.

2. The wall is not suitable for covering after installing the line pipeline, and cracking will occur when the wall shrinks.

3. When applying the cement of the wall base, the cement is not properly blended, and the cracks will easily occur if the cement is used more.

4. When scraping putty, cracks will appear if the putty is applied unevenly or the putty is not suitable.

5. When brushing latex paint, the contrast between paint and water is wrong, which will cause cracks on the wall.

Second, the wall crack treatment method.

1. If it is a temperature crack, then it is easier to do, which is also the crack we often see, this kind of crack will not have an impact on the structure of the house, but will only have some impact on the interior aesthetics. The solution is to paste a non-woven fabric or plastic mesh cloth on the cracked wall, and then repair it with some paint.

2. If you encounter settlement cracks, then you need to wait for the cracks to not continue to spread before processing, because the general house will sink within three or five years after the construction, and it will be stable after sinking to a certain amount, and the cracks will spread during the sinking period, so don't rush to repair it, wait for the cracks to no longer spread before starting to repair. The solution is to use cement and elastic putty, or use plaster to fill and repair, and finally brush the putty.

3. If it is a structural crack, then there is no way to repair it by itself, because improper repair will have an impact on the structure of the house, and the general treatment method cannot deal with this kind of crack, so it is necessary to find a professional person who understands the building structure to deal with it.

4. If the surface of the latex paint is cracked or the wallpaper is cracked, then the solution is to use sandpaper to polish the cracks, and then brush with new latex paint. If the wallpaper is cracked, soak the wallpaper with water, brush some glue and re-glue it.

5. If there are cracks in the putty layer, then you need to use a pointed tool, such as a screwdriver, to expand the cracks, then stuff some plaster, polish it flat, dip it with a layer of plastic mesh cloth, then brush with new putty, and finally brush with latex paint of raw wall color.
