There is a partial peeling of the wall, do you need to renovate it completely?

If you are not very old, you can scrape off part of the wall skin and re-apply putty and paint. If the area is too large, it is best to renovate the whole wall, otherwise it is not beautiful and not strong.

If there is local peeling, there is no serious peeling, you can do local renovation and rectification

In daily life, due to external factors such as the weather, or the quality of the wall paint itself is not up to standard, many families will have the phenomenon of wall peeling, which is very unsightly and affects the home environment and the mood of the occupants. Next, I will bring you four steps to turn your old wall into a new wall when the wall is peeling.

1. What should I do if the wall peels?

Step 1: Use a putty knife to shovel off the wrinkled and bulging wall plaster, until the perimeter and the wall are tight and cannot be shoveled off;

Step 2: Use a small roller dipped in the proportional interfacial agent (sold in paint stores), roll it evenly, and dry it naturally;

Step 3: (1) Add an appropriate amount of white glue to water, stir with putty powder, and drape it on the interface agent coating with a batch knife, draped it solid and flat, because it is the first layer of the coat, it does not need to be too much required to be smooth with the original good wall around it, but it cannot protrude from the original good wall and dry it naturally;

2) Repeat the program of (1), slightly protrude the original good wall, after natural drying, use No. 50 cloth sandpaper to smooth the peeling part of the wall, and then use No. 120 imported sandpaper to polish and flat, if there are conditions to buy a sand frame, you can put the sandpaper on the sand frame to polish is conducive to the smoothing of the wound, and the more strict requirements of friends can hold an incandescent bulb to shine on the concave and convex condition of the wall, and then selectively polish the convex part, and the friend with a large peeling wound can take a 3m long aluminum alloy frame to flatten the wall as a reference, depending on the specific situation. Step 4: If the wall peeling wound is large and many, you can consider re-brushing the cement paint as a whole, the wall peeling wound is small, you can use a brush dipped in water to gently brush the wound, (applicable to ordinary walls, the same applies to wood boards and calcium silicate board walls, and the white glue label is required to be more than 2000).

Second, the daily maintenance of the wall.

1. The dirt will stay soon.

If you find that the special dirt on the wall should be wiped in time, the method is to scrub the water-resistant wall with a cloth, and blot it with a dry towel after washing; For non-water-resistant walls, wipe them with erasers, etc., or use a towel dipped in some cleaning solution to wring them out and wipe them gently. In short, it is necessary to remove the dirt in time, otherwise it will leave permanent marks over time.

2. Attention should be paid to decoration.

When nailing nails on the wall, the wall is very prone to powder loss, you can use tape paper to stick to the place to nail in advance, and then nail the nail, there will be no more powder loss. If there are calligraphy and paintings, photo frames, etc. hanging on the wall, when they are removed for a long time, there will be traces on the wall, you can spray stain remover directly on it to wipe, if the stain is heavy and not easy to wipe it, you can use fine sandpaper to wipe it, and the force should be light when wiping. 3. Wax water maintenance is convenient and clean In daily life, the wall is mainly dust, water droplets and other splashes, cleaning and maintenance methods are to wipe off the surface of the floating ash every day, and regularly clean and maintain with fountain mist wax water, the wax water not only has a cleaning effect, but also forms a transparent protective film on the surface, which is more convenient for daily cleaning.

As living conditions get better and better, many people buy new homes. But I believe that many friends have encountered or are experiencing such a situation, that is, the wall at home has been used for a long time, it will crack, peel, and mildew on rainy days. These situations on the wall greatly affect the aesthetics of the home!

In this regard, many people will choose to decorate the master to get, in fact, it is not necessary, the following Chenyang paint will teach you a trick, and you can easily do it at home.

First, the reason for the re-dampness and peeling of the wall

Water seepage on the exterior wall leads to moisture return, generally due to cracks in the exterior wall, damage to the waterproof layer of the exterior wall of the building, or no insulation layer or insulation layer is not done well. The bathroom is not waterproof, and the wet wall leads to moisture and peeling.

Painting wall paint, paint or inlaid tiles before the putty is dry during decoration, as well as the use of putty powder and paint that are not up to standard for environmental protection and quality, will lead to mildew on the wall. Or the humidity in the room is too high during the rainy season, causing moisture to return.

When decorating, the waterproof construction quality of the balcony and bathroom is not up to standard, and the leakage of the water pipe will cause water seepage and moisture resurgence, or cracks at the junction between the baffle plate and the wall under the balcony window, or the poor sealing performance of the window may lead to external rainwater seeping into the room and causing moisture relapse.

Second, the treatment method of wall re-moisture peeling

If the area of the wall is large and there are multiple layers of mold, it is recommended to partially remove the surface of the damp peel and repaint it. First of all, it is necessary to remove the part of the surface that is damp; Use sandpaper, etc., to smooth the surface; The scope of façade removal should be appropriately expanded, which can be 50 cm higher than the existing moisture return height.

Use a brush or roller brush to evenly brush 2-3 times with waterproof and mildew-proof anti-mildew separator, and then brush horizontally, vertically, and horizontally again to ensure that the bottom liquid is fully brushed and evenly brushed; Each pass needs to be thoroughly dried before the next coating.

After the anti-mildew isolation solution is fully dried, stir the anti-mildew isolation layer with water to the paste and scrape the shoveled wall in batches, and scrape it to a level with the wall that has not been shoveled, this layer is mainly for mildew prevention and filling. Finally, use waterproof putty paste to repair the leveling, and then apply latex paint to partially repair the damp peeling wall.

First, the wall comes.

The peeling of the topcoat is mainly caused by self.

Caused by construction process problems, it can be dealt with as follows.

Second, the treatment of the wall paint bulging and peeling off.

1. When processing, be sure to scrape off all the damaged paint on the original wall, and then brush a layer of wall interface agent to prevent the putty in the gap from interacting with the new putty;

2. After the "double insurance" process is completed, paint the waterproof putty once, wait for it to dry thoroughly, and carry out the second putty painting;

3. After the waterproof putty is completely dry, flatten the wall with sandpaper, clean it up, and paint the wall paint or paint;

Note: The wall treatment is that the ash on the wall must also be cleaned up, otherwise there will be bulging and other phenomena.

Re-eradicating a partial patch will do.

If the wall is damp and moldy.

Bai normal is due to the local climate is relatively humid or the back of the damp wall dao water seepage in the past, resulting in the dampness of the wall surface You can deal with it like this: 1. Thoroughly clean the peeled and damp wall with a shovel.

2. Continue to remove the floating ash on the wall to prevent the floating ash from affecting the bonding strength.

3. Evenly brush the separator with a brush and apply it 2-3 times, with an interval of about 3 hours between each time.

4. After the isolator is dried, the putty can be scraped in batches, and the batch scraping time is not less than 24 hours each time.

5. After the putty is dried, carefully polish it with No. 180 sandpaper.

6. Clean the surface dust and paint latex paint 2-3 times, with an interval of about 6 hours between each time.

There are many old houses and even some new houses with peeling walls, which is actually very common, but it is also very troublesome, because the peeling walls look very ugly, and if they fall, they can hurt their families. It's just a superficial phenomenon, but it can have a big impact on our house. Here's a detailed introduction, why does the wall skin peel off?

and wall peeling renovation methods.

1. The construction process was reduced, and the construction team found during the renovation was not formal, and the owner was deceived.

2. Failure to follow the formal process 3. The use of inferior materials is very important, it directly affects our wall life and the health of homeowners. For example, the construction party uses glue instead of interface agent to save costs, and putty powder instead of putty paste, in which case the wall must be peeled and renovated.

4. Slight peeling for temperature problems usually occurs in the living room balcony area of the homeowner. Because the lighting on the balcony is better, this area is most directly affected by the change in heat, so it will be more prone to a slight **, which is usually not particularly severe.

5. If there are many reasons for peeling and peeling off the walls of the old house or the old house, such as soaking caused by water leakage, if we want to fundamentally solve these problems, we must peel and renovate the wall.

6. There are swag and graffiti on the wall if the wall says it was accidentally stained with wax and oil. These stains then react chemically with the latex paint to reduce the adhesion of the latex paint. This is often the case in the kitchen or children's room.

Wall peeling renovation method 1: remove the peeled part and re-scrape the putty 1, processing method: if the drum is slightly cracked or peeled off, if the base layer of the wall is relatively stable, the problem can be eliminated, and the edge of the removed part can be smoothed, then the putty can be scraped again, the primer is applied, and then the brush is applied again, and the selected material is selected.

The construction team can handle the peeling of the wall in a dusty and efficient manner.

2. Process: Remove the damaged part to the base layer, scrape off the putty paste twice, polish the latex paint again, and apply the topcoat twice (required).

Wall peeling renovation method 2: deep renovation 1, treatment method: If there is a large area of peeling off on the wall, it is time to consider whether to build and use the wall in accordance with the official process.

To cope with this situation, the original wall should be removed to the cement layer, filled with interface agent, and then carried out gypsum leveling (hanging net) and then leveling, the quality of the entire base will be much better, and the wall peeling renovation will be completed.

2. Process: wall removal of the base layer, hanging net processing, gypsum leveling, scraping putty paste, grinding, latex paint primer brushing, topcoat brushing twice (required).

Peeling of the walls not only affects the aesthetics of our homes, but the cracks can get bigger and bigger over time. If the situation is serious, it will bring us safety risks. These issues have a direct impact on the safety and comfort of our lives.

Extensive peeling of the wall is a very common problem, usually caused by aging, damp or damp wall surfaces, poor paint quality, etc. In this case, we can take the following methods to fix the peeling problem on the wall:

2.Priming: Priming is required before applying paints and coatings. Depending on the material chosen, the base is primed with an appropriate substrate primer to promote the adhesion of the paint and the stability of the paint.

3.Apply waterproof paint: If the surface of the wall is peeling due to moisture, you need to use waterproof paint to apply. This coating prevents moisture from penetrating into the wall and preventing the wall from becoming damp and loose.

5.Paint application: Choose the appropriate wall paint to apply according to your needs.

According to the area of brushing, wall paint is usually divided into two types: paint and water paint. Paint has strong hiding power and toughness, but it takes a long time to dry; The water paint dries for a shorter time, but the hiding power is slightly worse.

6.Repair gaps: After painting, if there are cracks or gaps, they should first be closed with fiberglass mesh cloth or gap filler.

In short, early repair can keep the wall beautiful, if the peeling is serious, it is recommended to ask a professional to repair it, so as to avoid repeated construction.

In our home life, I believe that many friends have encountered the phenomenon of peeling, cracks, mildew, fading and other phenomena on the wall of the house, so what should we do if these problems occur? In fact, when these problems arise, we must first find the cause, so that we can.

Get the right medicine. Achieve the effect of doing more with less. Let's take a look at the reasons for wall peeling and how to deal with wall peeling.

Reasons for peeling on the wall:

Reason 1: Caused by the loosening and pulverization of the base layer of the wall.

Reason 2: There are floating ash, oil stains, release agents, etc. on the surface of the base layer.

Reason 3: The moisture content of the base layer is too high.

Reason 4: The construction team is working in a high humidity environment.

Reason 5: Freeze before the paint dries.

Reason 6: There are cracks in the insulation layer of the original house, which causes the wall to crack during decoration.

Reason 7: Improper repair and painting after the wall is slotted, resulting in cracks in the wall shrinkage.

Reason 8: When plastering, the ratio of cement is not appropriate, and if the ratio is too high, it will crack.

Reason 9: The ratio of wall putty is inappropriate, or the scraping is not uniform.

Reason 10: The ratio of latex paint and water is not appropriate, resulting in cracking of the wall.

How to deal with the peeling of the wall:

1. Directly roll the brush topcoat to cover the part.

If it is a simple fading, it is generally recommended to take the way of a roller brush to cover a new round of primer and similar topcoat, but before construction, it is necessary to judge the quality of the putty layer of the wall at this time: choose the worst piece of the wall to fade with water, and then use a shovel to produce a shovel forcefully, if there is no chalking or falling off, you can directly use fine sandpaper to polish and smooth the treatment and brush the new primer and topcoat.

2. Scrape the peeling part and scrape the putty.

If the white wall or bare wall is partially bulging or slightly cracked and peeling, you can remove the problematic place, and smooth the edge of the shoveled part, scrape the putty again, apply primer, and brush again, but there may be a little color difference with the original wall.

Comprehensive construction is the same as redecoration, the amount of work is the largest, and it is suitable for walls with many cracks, peeling and powdering. First of all, the wall should be completely removed to the cement layer, if it is some houses that have not been renovated for a long time, it is necessary to remove the surface of the brick wall, and then fully construct and renovate the wall: level the wall.

Curing the base layer. Brush the interface agent.

Batch scrape three times of water-resistant putty.

Wall sanding. Apply primer.

Effect topcoat on twice.
