After a year of renovation, there are cracks in the wall, who should I go to deal with?

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.

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.

Generally, there are many reasons for cracks in the wall, which are mainly divided into four types.

1.The construction process is not up to standard. For example, in the place of slotted wiring, it is perfunctory if it does not follow the formal process.

2.There is a subsidence of the foundation on the floor, and there is an encounter"Boom"Wait.

3.The insulation walls of the building are informally treated. Because the insulation wall is spliced together block by block, if there is no formal process treatment, it will also lead to cracks in the wall.

4.There is a problem with the cement stucco layer. For example, the ratio of cement and sand, moisture content is not in place, etc.

Solution: For the wall cracks caused by slotted wiring and foundation subsidence, we must strictly follow the process construction: first of all, we must fill it with stucco plaster, and then paste bandages, cloth or kraft paper at the slotted parts or cracks, and then do other base treatments.

The non-standard process does not use kraft paper at all, but directly brushes, and cracks will inevitably appear after a long time.

In fact, you can consider repairing with brand anti-crack coatings, such as Nippon, Red Apple Paint and other brands of anti-crack coatings.

In your case, it should be caused by building settlement. As it is now, it will continue to be for years to come.

The reasons for the cracking of the wall after decoration are simply the following two aspects:

1. That is, there is no anti-cracking treatment in the place where the anti-cracking treatment should be done, or the anti-cracking treatment is done but the anti-cracking treatment is not standardized; Specifically, the places where the wall needs to be treated with anti-crack treatment mainly include:

1) The place where the original wall is cracked; (2) the place where the light wall and the load-bearing wall meet; (3) the place where the light body wall and the light body wall meet; (4) Where there are construction holes in the wall; (5) There are slots on the wall; (6) The wall has a hollow drum and delamination; (7) The place where the light body wall is connected to the top.

2. The materials and construction technology for the treatment of the base layer such as plaster putty on the wall are not standardized.

In the process of wall foundation treatment, the selected gypsum, putty, mesh cloth and other materials should meet the requirements of national standards, and at the same time, when scraping gypsum, putty and other treatment layers, it is necessary to wait for the wall treatment of the previous layer to dry thoroughly, and then carry out the follow-up treatment layer construction, such as after scraping the gypsum, it is necessary to wait for the gypsum to dry thoroughly and then scrape the putty, before the bonding of different materials, the interface agent must be used to treat the interface agent.

Solution: It is necessary to conduct a specific analysis of the causes of wall cracking, and then take corresponding anti-crack treatment measures to deal with it. The inspection methods include the quality inspection of the hollow drum delamination of the wall, scraping the cracks, and checking the crack depth for comprehensive analysis.

For the cracking of the wall due to the settlement of the foundation, this possibility is relatively small, if this situation really occurs, there should be more cracks in the indoor and outdoor walls of different floors of the same building.

This situation generally occurs in new houses, and it is recommended to do the treatment after 1 year, and the treatment method is to use kraft paper or caulking tape, gypsum powder and white latex, putty powder and latex paint treatment!

Wall paint cracking is a lot of new homes for owners, and after a period of renovation or even a very short period of time, you will find more or less cracking on the river surface. The cracking of the paint film on the surface of the wall will seriously affect the visual effect of the decoration of the wall. It can even cause the paint film to crack, which will affect the life of the wall.

If only the crack of the surface. Just use fine sandpaper to sand off the cracks, and choose the same color of the wall area to repaint.

There are many reasons for cracks, such as: building defects, including insufficient mortar mix ratio when mortar leveling, or cement mortar is not dry and ash, which will cause the cement mortar to crack after drying. It will cause latex paint cracks after the decoration is completed, and the other is that the decoration workers in the construction in order to shorten the construction time, the bottom is not completely dry when the bottom layer is polished, which will also cause this phenomenon.

If it is an irregular crack on the wall as a whole, it is the overall removal, and then re-construction, if the wall appears in a vertical line or a horizontal line into a straight line of cracks, it may be the wall insulation layer joint of the house or the wall expansion coefficient caused by the construction hole reserved during the civil construction of the building is not the same, the crack left, if so, only need to follow the direction of the crack, evenly remove the wall, and use elastic putty to lay the base, Paste the seam tape with glue, and then level it as a whole, and make primer and topcoat in turn.

Wall Crack Repair Steps:

1. Use a putty knife to scrape out the width of the gap, and scrape it into a figure-eight shape, with the outer width and the inner narrow.

2. Use gypsum block dry powder to plug the void, and the filling depth is not less than 30-40mm, which does not need to be filled with the wall, which is lower than the wall.

3. Brush 108 glue in the gap and paste the glass cloth or cowhide note.

4. Scrape 821 putty 2-3 times and smooth it with the original wall, and polish it with sandpaper after drying.

5. Adjust the wall paint, brush the sample first after the paint is adjusted, compare it with the wall color after drying, the color is close, the color difference is not large, and then paint the wall.

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.

If the home is dry and the walls are relatively damp, it is prone to cracks. There are many reasons for cracks, and the wall cracks are different, and the difficulty of repair and the method of repair are also different

Cracks in straight lines from the inside out. This is the reason for the settlement of the building itself. For example, a new home will have a sinking foundation within a year or two of the first occupancy, and then gradually enter a period of stabilization.

In the process of settlement, the wall will have horizontal or oblique cracks due to uneven settlement. Do not take any measures against the base layer during the settlement process, and wait for the settlement to gradually stabilize before dealing with the cracks. Solution:

Shovel off the cracked wall of the base layer - paste anti-crack bandages - batch putty - brush latex paint.

Local cracks and even cracks are more obvious. This kind of crack can be scraped off with a shovel blade after the heating is over, and then putty and latex paint are brushed. However, there will be a global and partial color difference.

It is recommended that the owner leave the leftover latex paint from the previous decoration, and when repairing it again, the original latex paint can effectively reduce the color difference.

Very subtle shallow cracks. This kind of crack is related to the wall being too dry in winter, do not rush to repair it after the end of heating, generally after the relatively humid climate in spring, the crack can heal on its own.

If you want to do it yourself, then you will dispose of the cracked paint and then fill it with water, so it may be different for you to have a different color in that place, so I suggest that you go to a professional to deal with it.

Go to the renovation company and ask them to send a craftsman to make up for it! Or you can buy some leak-proof ones yourself, such as glass glue, and stick them on!

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.

What should I do if there is a crack in the newly renovated wall? What are the reasons?

Putty scraping the wall can make the wall look softer and more delicate, that is, beautify and save materials. However, if the frankincense layer breaks, it is easy to cause a breakdown of the surface layer.

**Method: If the crack has penetrated into the layer of cement, you can also first use a sharp tool to enlarge the size of the crack with a screwdriver, fill the plaster crack riveting and abolitor light, use mesh fabric or kraft paper and then align the putty level.

Mainly due to the quality of wall paint products and the wrong operation in the construction process of wall paint. If the temperature is too low, the film-forming temperature of the wall coating cannot be reached, and a continuous coating film cannot be formed, which will also cause the paint on the wall to crack.

Treatment: If it is only a crack in the surface paint film, you can use fine sandpaper to polish the crack, and you can choose the same color wall paint as you can repaint. In addition, many consumers have made every effort to choose a good painting when they buy paint, especially when they see a carton that says "crack resistant" on it, thinking that using this paint can prevent the wall from cracking the product.

Gypsum cracks are divided into normal cracks and abnormal cracks. Normal cracks mainly refer to cracks in the plaster layer caused by the shrinkage of cement mortar. Abnormal cracks are mainly caused by insufficient materials or construction techniques. Normal cracking is difficult to avoid, but abnormal cracking can be avoided.

**Method: If vacuum cast in a large area in the plaster layer, the layer of the original plaster must be removed and the plaster layer of the cement mortar must be reworked, then leveled and painted according to the normal process.

The cracking of the sealing celery is mainly caused by the joints between the wall cutting reinforced concrete and brick ceramite, reinforced concrete beams and ceramsite brick door compartments, separating the joints between the plasterboard and the original wall panels. Cracks in the office board are mainly due to the surrounding environment or external forces. Drywall, prefabricated partitions and prefabricated floor slabs will shrink and change position, which will result in joint cracks, usually vertical or horizontal.
