How to deal with the roof peeling, and how to deal with the roof peeling?

1. The indoor roof peels off and falls off, and the reasons are roughly divided into the following situations:

1. If the top surface is damp, it is easy to cause the putty powder to peel and fall off, and the top floor is generally leaking rain, the insulation is not good, and the top surface is damp with condensation. The adhesion between the putty powder and the top surface fails, and the pulverization falls off.

2. Construction quality problems, poor quality of putty powder during construction, gypsum leveling layer is too thick during top construction, or 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, there is cracking and hollowing, the top surface is smooth, the adhesion between the putty and the top surface is insufficient, and the adhesive is not used in the construction process of the top oilman.

4. The cracking of the floor slab will also lead to the cracking of the base layer, causing the putty layer to crack and gradually fall off and peel.

Solution: It is recommended to ask a professional oiler to deal with it, first shovel off the peeling parts, check the cause, and repair it according to the reason.

The top surface needs to be treated with moisture, you can paint waterproof latex paint, you can seal the gypsum board, you can do an integrated ceiling, and choose the right method according to the actual situation and budget!

Second, the cause of peeling and peeling of the wall.

1. The peeling and peeling of the wall are mostly caused by water leakage or alkali reflux on the wall.

2. The bathroom peels off, and the putty is not water-resistant putty.

3. When scraping putty on the wall, continue the next construction without waiting for the putty wall to dry.

4. If you live in the old house for a long time, the wall will also be chalking and peeling.

5. Concrete walls, without special treatment, will also fall off.

6. When working on wooden boards, there will be peeling without special treatment.

Solution: 1. Latex paint peeling: We see a thin layer of skin with the naked eye, which is latex paint, so we only need to polish off the latex paint layer and then brush it again.

2. Water seepage and anti-alkali: It is necessary to treat the water seepage place before the batch scraping putty can be carried out, and the anti-alkali phenomenon requires a comprehensive roll coating treatment of oxalic acid. Choose water-resistant putty to scrape the wall.

3. The walls of the old house are seriously pulverized

First, if there is no serious peeling on the wall, choose the wall solid interface agent or adhesive for the cover, and then scrape the putty.

Second, if the base layer of the wall is pulverized, the wall will be seriously peeled and pulverized, or there will be floating ash, oil stains, and mold release agents on the surface of the wall base layer. In this case, the wall glue needs to be moistened the day before, and the wall is shoveled the next day.

4. For construction on the smooth surface of concrete and wooden boards, it is necessary to roll a layer of adhesive (tile adhesive), so that the batch scraping putty will not peel and fall.

Keep the wall dry, the wall base flat, and the putty should be scraped in batches, and try not to batch putty powder in rainy days, the air is humid in rainy days, and latex paint is prone to yellowing in the later stage.

In the process of decorating the old and new houses, the construction must be carried out in accordance with scientific methods, which can greatly reduce the trouble of moving in later and affect the normal life.

If it falls off in a small area, you only need to scrape the putty again at the place where it falls off. If it falls off in a large area, it is necessary to remove the wall skin around the falling off place first, and then re-apply the interface agent, scrape putty, polish the wall, brush latex paint and other processes, so that there will be no color difference.

Secondly, for the problem of sand cement ratio, in order to save money, increase the amount of sand and reduce the amount of cement, resulting in a very large probability of anti-sand. There is too much mud in the sand, which is also one of the reasons for the backsand. The problem of plastering surface is not big, the treatment is also very simple, shovel and repaint, if you want to save effort, wash it with water, brush it with glue or brush a layer of cement slurry.

For the problem of the roof wall peeling off due to the dampness of the wall, the wall should be treated with moisture in time. First, clean the peeling parts on the surface, clean all the white parts, and fix the wall after the wall is dry, it is recommended to use high-viscosity white powder to paint the wall.

Precautions for scraping putty.

1. The putty scraped is not a requirement for light, but for leveling.

2. It is necessary to pay attention to the putty on the wall, which is generally required to be scraped three times, but each time the putty is scraped, it is required to be painted again after it is dry.

3. When scraping putty, you must avoid cold wind blowing directly, so that although it seems that the wall can be blown dry, but in fact, the moisture of the wall is locked in the wall.

4. When the base layer is highly absorbent, it should be sealed with a primer before scraping and applying the putty, so as to avoid the rubber in the putty being too absorbed by the base layer and affecting the adhesion of the putty.

The above content refers to People's Daily Online-The thickness of wall leveling and scraping putty needs to be grasped.

Roof peeling treatment method:

1. Redo the walls. If the peeling of the wall is severe, the cement layer of the wall should be removed first, the dust should be cleaned, the wall should be kept clean and dry, and then the wall should be repainted.

2. Remove the spalling wall. During construction, use a spatula to remove the swelling or break the wall, and then use a small roller to soak the interface agent and apply it evenly to the wall.

3. Make the first layer at the bottom. Add some white glue to the bottom of the water, then add powdered putty, and then apply it to the wall with a tool to make sure the wall is flat, and finally apply emulsion paint to repair the wall.

How to prevent the wall from falling off:

1. Close the windows in the morning and evening to reduce humidity.

Humid air is very bad for the wall, so in daily life to prevent the humid air from entering the room, especially on a southerly day, it is necessary to close the doors and windows of the home, so as to avoid damp mold, bulging, falling off and other phenomena on the wall.

2. Check in time to remove water vapor from the wall.

When the weather is humid, check the humidity of the wall at home at any time, if the surface is already wet, use a dry cloth, air conditioner or dehumidifier to absorb the moisture in the wall, so that the wall will not mold and peel.

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.

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.

Decoration is a project with very high professional requirements, any link of negligence, there may be quality problems, such as simple white walls and ceilings, seemingly simple, in fact, the quality of coatings, construction technology, maintenance and other requirements are very strict, otherwise there may be problems in the short term. So, how to deal with roof peeling? What should I pay attention to when scraping white walls?

Let's take a brief look at it together. 1. How to deal with the peeling of the roof needs to remove the hollow parts around the peeling first, and clean it up, and then scrape the putty and brush the latex paint again. Because the part that has just been constructed will definitely be white, it is easy to have a color difference between the old and the new, and if the top area is small, it is recommended to re-construct the whole surface.

2. What to pay attention to when scraping the white wall 1. When scraping the white wall, first of all, we must ensure that the base has been cleaned and there is no unevenness, otherwise it will directly affect the flatness of the white wall. 2. If the wall has been scraped white when buying a house, and the owner wants to re-construct, it is necessary to remove all the existing coatings, or brush a layer of interface agent in addition to the existing coatings, otherwise it is easy to cause the new wall skin to fall off because of the existing coatings. 3. According to the experts of Qeeka Home, scraping the white seems simple, but in fact, the content is very particular, such as the temperature and humidity of the construction environment should be moderate, the number of layers of the scraping white, the construction process, etc., pay attention to the scraping of the white is generally more than two layers, and each layer of the white must be polished after it is dry.

4. After scraping the white, you can not open the window immediately for ventilation, because the wall surface that has just been constructed is relatively wet, and ventilation at this time is easy to lead to peeling, cracking, etc., it is recommended to close the window for 24 hours, and then ventilate, pay attention to the foggy or rainy day, you must close the window in time. Summary: The above about how to deal with roof peeling and precautions for scraping white walls are introduced here, I hope it will help you.
