Problems with interior decoration Cracks appear in the walls

Should not find others to be responsible, because the cement number of civil engineering is not enough, so it leads to cracks in the wall, that is, there will be cracks in the state of patching with cloth, to solve this problem is to cut off the cement on the wall and plaster it from the new plaster, there will be no problem, because when the weather is good, the air drying will lead to the joints, if the indoor moisture will not be fully responsible, this part of the cost will be very high!

Due to the high moisture content of the wall, the coating shrinks or expands with the change of air humidity.

From your description, although the wall was originally cracked, it is in a stable state, and if the substrate is treated properly, the original crack can be filled.

Now, if this situation is not treated, it should not affect daily use. If it must be treated, it is recommended to remove all the surface layers of the wall until the concrete wall or brick is exposed. Then choose the fine weather and carry out the construction in strict accordance with the specifications.

Expand and contract. It shouldn't be serious. Whether it is a crack in the wall or a crack in the surface.

If the wall needs to be pressurized, the slurry can be treated. If it is a surface, re-plaster the wall with mortar. What is the structure of your house.

Is that wall load-bearing or not, whether it is an interior wall or an exterior wall. You can let the decoration team come up with a plan and then do it. It's not a big problem.

As long as it doesn't affect structural safety.

It may be a problem with the cement on the wall, and there is also a relationship between thermal expansion and cold contraction. Since they promised you, they should be responsible, but it depends on their sense of responsibility, and there must be no documentary evidence.

This can be guaranteed, the crack can be repaired first, and then the patch treatment, in the batch of putty. It should be fine!

As a result, the wall will become moldy, the wall will fall off, and it will crack. Therefore, you should choose to paint the wall in summer or autumn, so that it dries faster and will not crack. And when painting the wall, you must find a skilled master to paint the wall, and the master must supervise the whole process in the construction process.

In this way, some corners can be avoided, and there will not be a lot of unnecessary trouble.

If it's a new house, you may have cracks in the walls caused by settlement, and there are cracks under both sides of the window sill. If it is an old house decoration, there are many reasons for the plastering layer or putty layer behind the shovel wall, the material or construction problem, or the temperature difference wall, and the wall cracking.

It is possible that in the process of construction, the formal process is not followed, or it may be due to the fact that the home is relatively wet, so it needs to be remedied in time.

This is mainly caused by open windows, especially in houses with short renovation time.

Wall cracks are the cracking phenomenon caused by the wall part of the building structure, which can be divided into the following four reasons according to the different materials of the materials themselves. Cracks in concrete walls, cracks in brick masonry walls, cracks in new partition panels, cracks in walls of different materials.

Patching Steps:

If there are cracks in a large area, the crack will be chiseled into a "U" shape on the base of the wall, and the spacing of the "U" groove is greater than 20cm, and the chiseled base will be chiseled, and then the steel wire mesh will be hung. The cracks are then painted with elastic decorative materials to compensate for the cracks in the walls.

Remove the insulation board on the surface of the wall, or remove the cement wall, install a layer of gypsum board or "five-centiboard" outside the insulation layer, and then make latex paint on it.

Shovel off the cracked paint film, fill the cracks with elastic putty, use elastic wall paint for construction, and use primer for the base layer with too strong water absorption, so as to avoid construction in the case of high temperature and low humidity, the paint film can not be too thick when painting, and pay attention to avoid excessive atomization when spraying.

This answer is applicable to the method of repairing cracks in the renovated wall.

After the home renovation construction is completed, what is the cause of cracks in the walls of the home?

After the decoration is completed, we all know that there will be cracks on the walls of the home, and some of the cracks are very large, which directly affects the decoration effect. New housecracks in the wallIt is a common problem of decoration. There are many reasons, it may be that the wall is too thin, it may be that the cement paint on the wall is not completely dry after the cement is painted, it may be a problem with the original building structure, or it may be that the penthouse is too stuffy and so on.

After the home renovation construction is completed, what is the cause of cracks in the walls of the home?

Analysis of the causes of cracks in the wall

1. Cracks caused by material quality.

The quality of putty and paint will also affect the decoration effect of the wall. Poor quality or counterfeit putty, the paint is prone to powder loss, cracking, falling off and other conditions.

2. Cracks caused by different materials.

Gypsum board may be used in background walls, ceilings, etc., due to the different materials of gypsum board and cement, moisture content, shrinkage, etc., so that even if the two parts are tightly bonded during decoration, cracks will occur after a long time.

3. Cracks formed by hollowing the wall.

Rough house due to the quality of the building may have a certain area of hollow drum, if the area is larger, it is necessary to knock off the hollow drum part, re-wipe with cement again, so that the junction of the old and new cement because of the different ratio of water loss shrinkage is easy to crack.

4. Cracks caused by putty on the wall.

When batching putty, the thickness is uneven, or the same wall is batched at different times, so that cracks will occur between the new and old putty due to drying and shrinkage.

5. Cracks caused by slotting and ash filling.

Cracks are also prone to occur after the trunking is filled, this is because the drying speed and shrinkage rate of cement mortar are different from putty powder, the putty on the surface of the wall has been dry, and the cement mortar inside has not dried thoroughly, resulting in cracks.

6. Cracks caused by poor pipe arrangement.

After the wall is slotted, when laying line pipes and water pipes, some workers cut corners and directly seal the pipes with cement without fixing them. There is no problem with such a wall at the beginning, but after a long time, the line pipes and water pipes will loosen, and cracks will also occur.

Wall cracking is mostly caused by cracks in the cement of the wall, or cracks in the joints of the wall "insulation board", or cracks in the lap of the old and new walls, or cracks in the connection between the trunking and the original wall after the plumber slots, most of them are not the quality problems of decoration, but the insurmountable defects in the building. In order to pursue the decorative effect, decoration can be used to compensate for architectural defects.

During the use of the wall at home, if there is a problem with the quality, it is easy to crack. What's the deal with cracks in the walls of the home decoration? PChouse will take you to find out.

1. Cracking of the wall structure, and the cracking of the wall caused by the subsidence of the foundation caused by the wall structure.

2. Cracking at the splicing of the old and new walls. The materials used in the new wall and the old wall, as well as the humidity and shrinkage ratio of the wall, are different, resulting in wall cracking.

3. The quality of the wall base material is poor, and the putty is cracked. Poor quality putty powder, generally water resistance is also relatively poor, the paint is liquid, the putty that is not resistant to water will appear pulverized after encountering the paint, and then there will be hollowing and cracking.

4. The base putty is scraped too thickly and cracks. If the wall base material is scraped too thickly, it will dry unevenly and crack easily.

5. The parts that are easy to crack are not treated with anti-cracking. Generally, the internal insulation wall of the home, the sand and gray wall of the old house, the light wall, the cement or gypsum and other base materials are of poor quality, the junction of the two walls, the slotting left by the hydropower transformation, the holes left by the construction and other crackable parts.

1. Shovel the wall skin, and remove the wall skin around the crack during construction, and then carry out the wall base treatment, which can not only prevent the wall from cracking again, but also make the wall and the paint film better bonded. 2. After painting the interface agent and shoveling the wall skin, the base layer should be cleaned to ensure that the base layer is free of dust and stains, and then the interface agent should be applied, which is conducive to better adhesion between the interface agent and the wall. 3. Filling leveling, after the interface agent is dry, it is necessary to fill and level the treatment, and the construction can be filled with fast-drying powder in the depression, and a layer of leveling treatment can be done first, which is conducive to subsequent construction.

Relevant knowledge development materials: 1. Lay the fiber net, and after the leveling work is completed, lay a layer of fiber net at the grassroots level. It not only controls the shrinkage of the wall, but also ensures that the wall paint does not crack with the deformation of the wall, so that the wall surface can be stronger.

2. After laying the fiber net, it should be leveled again. Pay attention to the leveling this time to be more serious and careful, to completely smooth the uneven places on the wall, so that the mesh and the wall are fully fitted together. 3. Pay attention to the completion of the painting in accordance with the requirements, and pay attention to the construction environment, so that the paint surface will not crack due to environmental impact.

After the painting is completed, it is necessary to take protective measures in front of it, and do not touch it immediately to avoid leaving traces.

The first picture is damp, water leakage caused by the wall peeling, you should first check each inlet connection near this wall to see if there is any water seepage, if so, first solve the waterway problem, and then find an oiler to come and repair the wall. There are many reasons for the cracking of the wall with putty and wall paint, including the reason for the wall itself, the reason for the dampness of the soaking water, and of course, the possible construction reason. What should I do if there are cracks in the wall after a year of renovation?

<> cracks are mainly concentrated in the last part of the bay window, and there is water seepage on the left side of the bay window and the lower side of the bay window. Everyone found that the cracks and water seepage of the walls here are all in the bay window. In fact, over the years, this problem has become more and more prominent, and it is really necessary for everyone to understand this knowledge.

Let's take a look at the structure of the bay window first, and then determine the treatment plan. For our renovated house, it is not uncommon for cracks to appear on the wall after living for a period of time, and there are actually many reasons for these cracks on the wall.

Strictly speaking, after the house is renovated, a professional home inspector will be asked to check whether the quality is passable, and only after meeting the standard can you move in. However, cracks in the walls of the house after a year of renovation are mainly due to improper construction, subsidence of the foundation of the real estate, informal treatment of the insulation wall, and problems with cement painting. Now that we know why, what are the remedies?

It is mainly a problem of the quality of wall decoration construction, or the problem of civil plastering layer. Check the crack with a blade, if it is putty, the latex paint is cracked, and re-repair it. Paste caulking tape, scrape putty, brush paint.

Determine the cause of the problem, is the wall cracking, the foundation decoration contractor will maintain, if the original cement is not removed during the decoration, this needs to find the property developer to solve, according to the contract, generally now the warranty period of the project is more than 2 years, or find someone to deal with it yourself.

You should deal with it yourself, you can go out and find some professional masters, and re-deal with these cracks for the home, so that the home looks very beautiful.

This problem may be that the wall paint is too thick during decoration, and you can find a decoration worker to maintain and repair the wall paint. There may also be a problem with the wall itself, so you have to find a property.

For the masonry structure of the house, the top and the masonry are mutually constrained, in the case of constraints, if the temperature between the roof and the masonry is not coordinated under the condition of external temperature change, the masonry will produce temperature stress, for the masonry itself there is a limit value of tensile and shear strength, when the temperature stress exceeds this limit, the masonry will have temperature cracks.

Solution: For our house, there are still many cracks, and the cracks in the house will seriously affect the aesthetics of the interior, the solution is that we can paste non-woven fabric or mesh cloth on the cracks, and then we can re-scrape the putty and paint it, so that the cracks will not be visible.

Situation 2: Because of the cracks in the latex paint, if there are such cracks in our house, the solution is actually relatively simple, we can first use fine sandpaper to polish off the cracks in the latex paint, and then we can use the latex paint to repaint it, if this feels uneasy, we can shovel the cracks, and then re-scrape the putty and paint.

Situation 3: Because of the cracks in the building structure, the expansion joints of the structural wall of the house and the brick wall will also extend to the surface of the wall, for this kind of crack is also a more common crack after our home decoration, and it will also be manifested as a crack formed by latex paint.

Solution: It is relatively difficult to deal with this kind of crack, we need to shovel all the base layer of the wall, after cleaning the crack, we use epoxy resin to fill the gap, use carbon fiber anti-crack cloth on the surface of the crack to reinforce the treatment, and finally we can re-scrape the putty and paint it.

Situation 4: Because of the cracks in the cement stucco layer, this situation is mainly because when we paint the wall, the mixing ratio of cement and sand is not right, which leads to the cracking of the cement stucco layer, and finally leads to the cracking of latex paint.

Solution: In this case, we need to remove the cracks at the position of the cracks and see the cracks made by the cement painting, and then we paste a carbon fiber anti-crack cloth at the location of the cracks, and then re-scrape the putty and paint it.

Situation 5: Because the putty layer is cracked.

If this happens to the walls of our home, it is mainly because the thickness of the putty layer is too thin when we paint the wall, which leads to cracking.

Solution: In such a situation, it is relatively easy to solve, we can directly paste carbon fiber anti-crack cloth or log pulp bandage on the crack, and then we continue to scrape putty and paint.

Because it is for several different situations, I share with you some solutions to cracks in the wall, I hope it will be helpful to friends in need.
