What are the solutions to the peeling and falling blocks of the indoor roof?

The problem of dampness needs to be solved first, otherwise it will also fall off. It can be moisture-proof, but it depends on the reason for its peeling and whether it is serious.

This situation can only be solved by shoveling off the original skin, re-approving the roof, scraping it with putty glue and milky glue and gypsum powder, plastering, sanding, and painting.

No matter what it is, it will change with the passage of time, when we decorate, some of the furniture in the home will wear out because of time, in fact, the walls are the same, and they will fall off because of time.

If you're damp, find a master who paints the walls, shovel all the putty off the roof, and then apply a new plaster, then apply putty powder, and finally paint the latex paint, and it should be fine.

Shovel off all the previous skin, re-apply the plaster, apply putty powder, and brush it again.

You can just pull off the original skin and brush it again, but it's a bit time-consuming and money-consuming.

The floor slab is made of pouring concrete in the main construction, so the surface of the roof of this layer is concrete.

I believe everyone has encountered that when the house is old, there may be peeling, and then we must find the reason before we know which method to use correctly. Let's introduce to you how to solve the problem of roof peeling.

How to solve the roof peeling.

1. Generally speaking, it is a putty base problem, and the solution is to replace it with better putty, and pay attention to eradicating the old putty before brushing.

2. If the adhesion of the base layer is relatively poor, it will cause the wall to crack and fall off. Solution: Increase adhesion.

3. If the indoor temperature causes cracking. Solution: Don't open the windows too often to reduce the indoor humidity.

How to prevent the wall from moisture.

1. Close the windows in the morning and evening to reduce moisture ingress.

If the weather is too humid to the wall will bring harm, first of all, to prevent moisture from entering the room, when returning to the south of the day, special attention can not be opened, so as not to give moisture the opportunity to sneak in, generally speaking, the window closing time is every morning and evening, relatively speaking, the humidity during this time is relatively high, if you do not close the window in time, water vapor will enter the room, the window opening time can be selected at noon, the time can not be too long.

2. Use desiccant and other products to absorb moisture.

For example, you can consider buying some desiccant and other products, reasonable use can reduce the indoor humidity, and you can also consider using lime, laundry detergent and other these to absorb moisture.

3. Use air conditioners and dehumidifiers.

You can also use dehumidification appliances, you must know that most of the air conditioners now have a dehumidification function, so you can use this function when you return to Nantian, and you can also consider buying a professional dehumidifier, although it is higher, but its dehumidification effect is better.

4. Check and clear the water vapor on the wall in time.

When the weather is more humid, check the condition of the wall, if you find that there is condensation on the wall, then you should take measures, such as using a dry rag, dehumidifier, etc. to absorb the moisture from the wall.

Summary: The relevant content of how to decorate the roof peeling is introduced here, and the appropriate method can be selected to solve it according to the actual requirements. If you want to know more about related knowledge, you can consult Qijia.com.

There is a leakage in the waterproofing of the concrete floor slab on the top floor of the building, which will cause water to leak into your home when it rains, resulting in the return of moisture and mildew on the wall in the room, but this kind of possibility is not large, because the water leakage is generally more significant, and the leakage part will be more irregular, so you are not likely to be due to the problem of waterproofing. The top floor of the building is not very well insulated, resulting in heat and cold, resulting in condensation, this situation is generally more common in the northeast in winter, because your home is the top floor of the building, the general thermal insulation is lacking in the corners of the roof and the wall, this possibility is very large, it is proposed to improve the wall insulation countermeasures, should be able to **.

Why is it that the problem of concrete floor slabs and external insulation of external walls is only moldy at the foot of the wall? Could it be that the other roofs and walls are not insulated and insulated? However, it is very likely that thermal insulation in other places is not good, so why is there no mold?

That's because when there is moisture on the indoor wall, there will be a cyclone in the room due to open windows for ventilation or people walking, which will make the top of the wall dry and irritable, and it is not easy to grow mildew. Therefore, it is easy to grow mildew on the back of the bed in the bedroom. The premise is that the walls are all walls.

Such a thing may be caused by the leakage of the wall into the walls of your house, and then seep into the room along the concrete, it is very likely that the leakage is not big, so it is not very easy to be found, and there is not much seepage, so it can produce this kind of clammy and cold situation at the foot of the wall, and if you are in this clammy and cold situation for a long time, the wall will grow moldy and peeling! The treatment method is to brush the waterproof architectural paint on the wall and roof at the mold, and the total area should be brushed as large as possible, about two or three meters above and below the mold in your corner, and all the way to the top of the ring beam should be brushed with waterproof architectural paint, and the concrete floor slab of the roof including the foot of the wall also needs to be brushed. Since the concrete will spread when it sees water, it may leak not far from the foot of the wall.

If you live in a high-rise building, it shouldn't be too humid, it may be a roof leak, you can ask employees to check the waterproofing of the roof, according to your description, it should be a roof leak, and you can observe whether the water leakage is aggravated on a rainy day.

The surface of the cast-in-place slab is provided with a release agent. We all know that the concrete floor slabs in our rooms are made of frame templates, binding steel bars, and pouring concrete. In order to realize the separation between the template and the cement, and facilitate the removal of the board, a layer of release agent is generally brushed on the template.

The existence of the template release agent is a serious harm to the bonding of the putty powder, therefore, most of the putty powder will fall off if the putty powder is not solved immediately if the release agent is not solved. When the height difference of the cast-in-place slab is too large, the appropriate treatment method should be to apply high-strength mixed mortar to carry out batch putty ground leveling. In other words, before approving the putty, we first use mixed mortar to level the ground of the cast-in-place slab.

If putty is applied for leveling, the scraping layer of putty powder is too thick, and the conclusion is that the putty powder has fallen.

It may be that it is often not ventilated, it may not be thoroughly dried, it may be that the quality of the material is too poor, it may be caused by the subsidence of the foundation. The skin of the wall should be removed, then re-sanded and repainted. You can add some white gum to the water.

There are many reasons why the roof and wall skin fall off, it may be damp, or it may be in the process of decoration, the ratio of cement and lime is not right. Repairs should be made in a timely manner.

The wall is not treated well, and the materials used are also related to a certain extent, which needs to be eradicated and then repainted, and the wall can be sanded rough.

1. If the roof is peeled, the falling part should be removed, and the removal range can be appropriately expanded by about 10 cm. 2. After grinding and smoothing the removed part, select the appropriate putty powder, mix it evenly according to the specified proportion, and apply it to the wall, and it is better to scrape the putty twice. 3. Wait for the putty to dry completely, and then reapply the primer and topcoat, in order to ensure the appearance, it is best to repaint the overall roof, otherwise there will be color difference.

1. The peeling of the roof may be due to the improper proportion of putty powder or the uneven stirring, which will lead to improper treatment of the base surface of the wall, so that even if the latex paint is brushed in the later stage, it will crack or fall.

2. In case of humid climate or the rainy season, it will cause the phenomenon of peeling on the roof.

3. Pay attention to grasp the time when carrying out construction, and dry and dry thoroughly after each link is completed, and remember not to carry out the next process when the wall is not dry. Each process must ensure that the wall is thoroughly dried before construction, otherwise there will be a phenomenon of wall peeling and falling off.

4. In the process of construction, it is necessary to choose a more experienced decoration team to carry out the construction as much as possible, and at the same time, it is necessary to measure the size and height of the ceiling in strict accordance with the construction requirements before construction.

First of all, the peeling wall skin should be shoveled off until the cement wall is exposed; Secondly, polish the wall flat, if the wall is uneven, it is recommended to scrape a layer of putty and then level; Finally, apply the primer twice and the topcoat three times. Note: You must wait for the previous paint to dry thoroughly before you can brush the next one.

Reasons for the peeling off of the roof wall:

1. Under normal circumstances, there will be a foundation settlement phenomenon in the new house for 1 to 2 years, so it will inevitably cause the wall to stretch, resulting in cracks, peeling and cracking of the wall. When facing the settlement of the foundation, do not rush to repair the wall, but wait for the settlement period of 1 to 2 years to gradually stabilize before repairing the wall.

2. Since the real estate developer uses plain ash to smooth the wall before handing over the house, workers must remove the plain ash of the base layer and repaint the primer before painting the wall. If the construction personnel do not treat the base layer in place during the decoration, it will lead to a large area of peeling and cracking on the wall after brushing the latex paint.

3. Of course, the unreasonable design, material selection and structure will also lead to the problem of roof and wall skin falling off. For example, CMC and CMS will react when added to lime calcium powder and white cement, which will cause depowdering of the wall.

Or add an appropriate amount of gray calcium powder or white cement to polyacrylamide, which will also cause depowdering due to chemical reaction.

Answer 1: Remove the shedding layer and deal with it in a targeted manner according to the following situation. 2. Polishing the old wall to increase the surface roughness, and then treat it with an interface agent (10% environmentally friendly glue or a special interface agent for sleeping treasures). 3. Use degreasing and cleaning agent to remove the release agent or other grease components on the surface, and then apply putty.

4. Use two-component or special plywood putty for construction. 5. Marble, mosaic, tile and other exterior wall surfaces should be made with special exterior wall renovation putty. 6. Use the putty within the shelf life.

1. The quality of the putty base layer, such as the original putty is not eradicated, and the quality of the original putty layer is poor.

Solution: Replace the putty of ***, and the old putty must be removed before refreshing the putty.

2. The adhesion between the latex paint and the putty base is poor, and it cracks and falls off.

Solution: Increase the adhesion of latex paint.

3. The convection air is too strong, and the temperature and humidity change greatly, resulting in cracking.

Solution: Don't open too many windows and reduce the indoor humidity.

The roof peeling generally does not exceed these reasons: first, the base layer is too thick and easy to shell and fall.

Second, the base layer does not dry out, causing the surface paint to peel.

Third, the original base of the house did not roll glue.

Fourth, water seepage upstairs leads to peeling.

This can be repaired, it is recommended that it is best to shovel it all, and it is most ideal to use white cement to cover the bottom The actual situation is still to be seen before you know what solution to use to solve it.

In this case, most of the walls are damp, causing the wall surface to fall off. Now the wall should be treated with moisture in time.

Treatment: Clean the peeling places on the surface, clean all the white parts, and fix the wall after the wall is dry.

In the rolling house, when the mud is scraped, there is no air in the middle, first it blisters, and finally it slowly becomes like this.

Huhu, my family also uses this situation But my house is 15 years old, this is the original decoration when the waterproof is not done, if there is no large area of this situation, that is, the corresponding position upstairs for a long time flooding. Generally upstairs problem.

The water vapor at home is heavy, and the paint of the paint is raised and falling off!! It is advisable to repaint the !! after cleaning

It may be that the humidity of the air is too high and too damp.

The saying in the Northeast is anti-frost, that is, the house is not dried and the decoration begins. There may be a water leak upstairs.

There is water seepage in the upstairs resident's home, do you see if the location of the upstairs owner is not waterproof? Washroom or kitchen location?

Many people's roofs are not specially decorated, generally latex paint is applied directly after priming. However, due to dampness, incorrect construction, etc., the roof may bulge, peel, or even fall off piece by piece. So what can we do with the peeling of the house?

Spalling of the roof can be repaired on its own. If it is a quality problem of the putty base, it can be removed and replaced with a putty; If the cracks and peeling are caused by the poor adhesion between the latex paint and the putty base, the viscosity of the latex paint can be increased; If the convection air is too strong and the temperature and humidity change greatly and causes cracking, the indoor humidity must be reduced.

1. If the top surface is damp, it is easy to cause the putty powder to fall off. Generally, the top floor leaks rain and the insulation is not good. There is condensation and dampness on the top surface. The binding force between the putty powder and the top surface fails, and the powder is pulverized and peeled off.

2. Construction quality problems. The quality of putty powder is poor during construction, and the gypsum leveling layer is too thick during the construction of the top surface, or the putty layer is too thick, which is easy to cause the putty layer to crack and hollow, and then cause it to fall off.

3. The quality of the top cement mortar plastering layer is poor, the cracking is hollow, the top surface is smooth, the bonding force between the putty and the top surface is insufficient, and the top oiler of the adhesive is not used in the construction process.

4. The cracking of the floor slab will also cause the cracking of the base layer, resulting in the cracking of the putty layer, which will gradually peel off and peel off.

You can brush it directly, but it will be uneven, so it is best to clean up the peeling parts, and then use putty to mend the defects. If there are cracks, they should be soaked in kraft paper and pasted, and then repaired with putty, and after the putty is completely dry, then sandpaper again. In this way, if you paint latex paint, it will look better and be more compliant.
