The walls at home are peeling off badly, how can we completely improve them?

If the water leakage problem is not serious, why is the wall peeling phenomenon so bad? I carefully inspected the paint film and putty layer on the surface, and gently wiped it off with my hand! I suspect it's a quality problem with the raw materials?

Substandard materials and leaks will inevitably fall off. In order to prevent similar problems from occurring again in the future, a layer of wall solid or waterproof paint should be painted on the wall during renovation, and the leakage position should be plugged from outside the wall.

<> cement, elastic or waterproof putty alkaline; Ordinary putty neutral; Paint acidic. Therefore, the paint should have two layers: bottom + surface; The primer is responsible for sealing, isolating, and increasing adhesion.

If the primer is not done well + the surface coating is not alkali-resistant, the acid-base reaction precipitates water, the white wall turns yellow, the color wall bites, the putty and the base layer of the adhesion decreases, and then a large area of peeling. The rough house will be renovated after a year, the walls will be cool, dry and cool, and the chemicals in the cement sand paddle will be reactive.

The most money-saving way is to buy oxalic acid before the powder wall to burn it, oxalic acid is relatively cheap, about two dollars a catty, a set of 120 square meters of house 30 catties is enough, some particularly humid areas will have a small area of anti-alkali after burning, after grabbing it again, putty powder will not be taken off, it is important to note that if the wall near the bathroom is not well handled many times, it must be that the bathroom waterproofing is not done, and the bathroom waterproofing should be redone.

With the gradual evaporation of water, hydroxide is precipitated from the concrete cement surface, accumulating over time, so that the original decorative paint or paint is jacked up, no longer adhering to the wall, whitening, peeling, falling off, this process is called "pan alkali". What should I do if the walls at home are peeling off badly? The answer I gave:

Find out the reason for the peeling of the wall, according to the actual situation, shovel off the peeling wall, clean it up, and redecorate the wall.

You can use a shovel blade to remove the damaged wall surface, and sandpaper the surface of the wall to keep the wall dry and clean. Apply a layer of cleanser. Seal the base layer and improve the adhesion of the wall, so that the putty can be better bonded to the base surface.

Use a scraper to scrape the damaged part of the wall paste or putty powder back and forth to make up for the cleaned place, and if the wall is damaged, it can be applied many times until it is flush. Apply the wall paint evenly to the repaired wall, and after it has dried, apply the wall paint again.

You should remove the moisture, put some desiccant in the corner, get a dehumidifier in the house, and then go and repaint the wall to completely improve it.

It should be re-shoveled, and if there is such a problem, it may be that the material used is not good, so it should be re-brushed.

1. Use a putty knife to shovel off the wrinkled and bulging wall plaster, and the perimeter and wall are tight until they can't be shoveled off;

2. Use a small roller to dip the proportionally prepared interface agent, roll it evenly, and dry it naturally;

3. Add an appropriate amount of white glue to the water, stir with putty powder, and drape it on the interface agent coating with a knife to drape it solid and flat, because it is the first layer of the coat, it does not need to be too smooth with the surrounding original good wall, but it cannot highlight the original good wall and dry it naturally;

4. If the wall peeling wound is large and large, you can consider repainting the cement paint as a whole, and the wall peeling wound is small, so you can use a brush dipped in water to gently brush the wound.

This answer is suitable for the repair of the wall peeling in the case of the large spine part.

Use a shovel to clean the peeling area, sand it with sandpaper, then apply the interface agent, and use relevant materials to smooth the wall.

First of all, the original base layer putty is removed, and then the putty is scraped again, and the bottom glue is applied again, and the remedy can be successfully remedied when it is dry.

I think this situation may be due to the fact that the wall is not fixed when the putty is scraped, and the wall can be polished clean and repainted to ensure that the indoor windows are open and ventilated.

Solution: The other side of the toilet wall often resurges, if you want to deal with this situation from the source, you must make the surface of the wall waterproof again. That is, the floor tiles are dismantled, and then the polymer concrete waterproof architectural coating is applied. After the waterproofing is up to standard, the floor tiles are pasted on.

Precautionary measures: There are two treatment methods that can be used at this time, but the correct way for them to do it is to do waterproofing of brick joints. The first countermeasure is to brush waterproof glue on the brick joints at the same time, but the joints must be cleaned and tidy.

The second countermeasure is to remove the brick joints and then make tile joints. In addition, special attention must be paid to the fact that if there is a gap in the wall tiles, this gap must be repaired with glue to prevent it from seeping along the gap.

The exterior wall was caused by a leak in the exterior wall. When it rains, the precipitation drives down the walls, and if there are cracks in the outer walls, it gradually penetrates into the inner and outer walls of everyone. This causes the interior and exterior walls to peel and fall off.

The waterproofing of the façade suffered damage. For example, the commonly used exterior walls are brushed with real motor paint, or wall tiles, or installed building curtain walls. Either way, as long as there is a gap, the water will flow through the gap.

There are gaps in the body. After the water is stored in the external wall, if the waterproofing of our wall is up to standard, then the water will not seep in. However, in general, most of the exterior walls have gaps, so if precipitation penetrates, it will gradually seep into people's rooms along these gaps.

Root removal countermeasures: If you want to remove the resurgence of the inside of the exterior wall, then you need to deal with it from the exterior wall. Searching for the actual leakage of the façade is very difficult.

It can be remediated by using the method of grouting of interior and exterior walls. Apply high-pressure grout to the place where the moisture resurgence occurs, and introduce epoxy resin glue, so that the building water will be blocked. Second, the epoxy cement permeable crystal can be brushed on the inner surface of the wall, and the coating of the epoxy cement permeable crystal can be used to prevent water penetration.

It is necessary to find out the cause first, whether it is because of the wall decoration falling off due to water leakage, or the quality of the raw materials of the wall causing the wall to peel. In this case, first of all, all the putty layers of this wall should be shoveled; Then, find the root cause of the wall leakage, and check whether there is a quality problem in the wall base; The third step is to paint the wall solid and waterproof paint on the wall during the renovation, and repair the infiltrated parts; The fourth step is to select good quality putty powder and wall paint for batch scraping.

It is very likely that there is a leak in the roof, it may be because the waterproofing project was not done well during the renovation, it may be because of the sun exposure, or it may be because the putty is not shaved well.

It may be due to the material. Many rooms are coated with inferior materials, causing the walls to peel. Use some paint to repaint the walls.

If the skin of the wall falls off, we have to deal with it differently depending on the situation. If the wall skin is partially peeled off, then only the peeled part needs to be removed, and then a small area of putty scraping is sufficient; If the wall skin is a large area of peeling, then it is necessary to remove all the places where the wall has fallen off, and then re-scrape the putty to repair the wall skin.

Reasons for this:

1. The wall skin may be settled in the house foundation, when the wall foundation is settled, the wall will be stretched in this process, resulting in the situation that the wall skin is dropped.

2. It may be that the workers did not clean the base layer at the beginning of the construction, and then began to paint the latex paint, which will lead to the latex paint and the wall not being 100% fitted, and the latex paint will easily fall off the wall after it dries.

3. It may be caused by the fact that the stirred mortar is not used up in time. If the mortar cannot be used at the right time, the mortar will be parked for too long the next day, resulting in a weakening of its adhesion, which in turn reduces the adhesion of the mortar to the wall, and eventually leads to the wall skin falling off. Therefore, when decorating, the materials of the day must be used on the same day.

Now it is not easy to buy a house, because the house price is very high, then the house needs to be decorated after buying, if the decoration is not qualified, it will be easy to appear this phenomenon of wall peeling, especially if the part of the home is wet by moisture, it will fall off piece by piece, which affects the appearance very much, and even will cause serious damage to other parts of the interior that have been decorated, and will cause people to be unable to move in. <>

First of all, when there is a peeling phenomenon at home, we must solve the problem for the cause, and then deal with the peeling problem, if the wall is only slightly peeled off, you can re-brush the interface agent locally and then apply putty, but after operating in this way, the color gap between this place and other places will be very large, if the peeling area is relatively large, then it is best to do a good job of cleaning up the grassroots, shovel off all the original latex paint, re-approve the wall, and then apply a new layer of latex paint, If it is a newly renovated home, I still recommend using the second method, because after this method operation, the overall wall still looks very new, and it will not form a strong gap with other walls. <>

If you want not to let the wall peel, first choose the material, the above is very critical, when decorating a new house, we try to choose high-quality wall paint, so that to a large extent can prevent the phenomenon of wall peeling in the future, do not choose poor quality because of a temporary cheapness, must be purchased through formal sales channels, choose qualified products, especially paint, will pay a greater price in the future. In addition, strict control of the construction process is also very important, in order to better prevent the wall from peeling, there are many details that need to be paid attention to, when the home is decorating, it is best to stare at the paint master yourself, so as not to cut corners when they are working. <>

If the peeling of the wall is serious, you can remove the wall and re-lay it, or you can choose to paste the wall with wallpaper or paint it again with latex paint. The windows of the room are opened and well ventilated.

When decorating a new home, if you find that the wall is peeling, you can choose to use some tools to remove the peeling parts, and then scrape the wall with the same paint or putty.

The windows should be opened for ventilation in time, and the decoration master should be called ** to seek a solution, or let them come to see it on site to help them solve the problem of wall peeling.

Peeling walls is a common problem in old houses, which can affect the aesthetics and longevity of the house. To this end, solving the problem of wall peeling must be dealt with in a timely manner, and here are some ways to deal with it:

1. Clean the wall: The reason for the peeling of the wall may be because of the long-term accumulation of dust, grease and attachments on the wall, which affects the adhesion of the paint. Cleaning the wall can be wiped with a rag dipped in soapy water or detergent to remove the attached dirt.

2. Repair the wall: After cleaning, use the repair cement provided by the interior decoration manual to fill the wall to fill in the large scratches, cracks, dents and other problems on the wall. After waiting for the cement to dry, use sandpaper to sand and align the wall surface.

3. Primer: Primer is an important step, which can enhance the easy adhesion of the paint and make the surface uniform. In crafts such as wallpaper and wallpaper, primer is also essential.

4. Choose high-quality wall paint: Paint is the last line of defense for wall protection, and choosing high-quality wall paint can increase the anti-peeling, waterproof, moisture-proof and other functions of the wall. When choosing a wall decoration paint that meets your needs, you should pay attention to some details, such as color, quality, paint film thickness, durability and other information.

5. Proper maintenance: Decorative materials should be properly warranted, and the account should pay attention to the maintenance of the wall, and carry out regular cleaning and cleaning, such as wiping the wall with a damp cloth to clean the wall, avoid hitting the surface with key points, and avoid using spicy and aggressive chemicals when touching and groping. At any time, during the rainy season with a wet utensil to sprinkle water, make sure that the windows are leaky and the door of the hosiery is rigid to avoid moisture.

In this way, the wall surface can remain in its original shape for a long time, even during the rainy or wet season.

1. Dispose of the old wall and scrape the putty. If it is a partial peeling, then remove the peeling part and re-scrape the putty in a small area. However, if there is extensive peeling, then it is necessary to remove all the peeling parts and scrape the putty again.

The former may have the problem of color difference, while the latter has a relatively large amount of work.

2. Strengthen the base layer. If the wall is peeling and peeling on a large scale, the first thing to think about is whether there is a problem with the bottom layer of the wall. During construction, it is necessary to re-reinforce the base with Gordon refreshing wall reinforcement, and then we will take a series of steps such as plaster leveling, pasting mesh cloth, brushing primer and painting.

3. Brush the top coat to cover the cracks. After the survey, if there is no chalking or peeling, for the place where the peeling is not very serious, you can directly apply the topcoat to cover, which should be the best situation.
