How to deal with the peeling of the indoor wall of the building

If there is a damaged place on the wall, first repair it with the three bags of powder and a little glue, then polish it with an abrasive cloth, and then buy a medium wall paint roller brush twice. Not for high quality, but for the wall to appear clean and refreshing.

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 after shoveling, scrape the putty again, apply primer, and then brush and repaint, so that it can be repaired in time, but there may be a little color difference with the original wall.

For the case of severe local spalling, it is necessary to consider whether it is the reason why the wall base is not done at all. Remove the original wall to the base layer of the wall, repaint it with an interface agent or sealing primer, and then polish it according to the plaster leveling, paste the mesh cloth (reinforcement and crack prevention), and scrape the wall lining three times, and the quality of the entire base will be much better at this time.

Most of the peeling of the wall is caused by water seepage in the bathroom or the exterior wall You can check it first to see if it is **infiltrated My family also had such a situation before, and the external wall seeped into the indoor wall Later, a friend recommended a product bought online to solve it.

Finally, spray moisture-proof to prevent moisture from penetrating.

How to deal with wall peeling:

1. 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 area, and smooth the edge of the shoveled part, scrape the putty again, apply primer, and brush again.

2. Professional reinforcement treatment for the grassroots level.

Remove the original wall to the base layer of the wall, repaint it with an interface agent or sealing primer, and then polish it according to the plaster leveling, paste the mesh cloth (reinforcement and anti-cracking), and scrape the wall lining three times, and the quality of the entire base will be much better at this time.

3. 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, 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.

4. Demolition of the old wall and comprehensive construction and refreshment.

First of all, the wall should be completely removed to the cement layer, and the house that has not been decorated for a long time needs to be removed to the surface of the brick wall, and then the wall should be fully renovated: leveling the wall - curing the base layer - brushing the interface agent - scraping the water-resistant putty three times - grinding the wall - applying the primer - applying the effect topcoat twice.

1. The big white is generally about 50 a flat, scraping the big white is a kind of interior wall decoration of the building, the thickness is about 1mm, it is good after drying, and it will not fade easily. It's just that I'm afraid of water, if it's soaked, it will fall off if you scrape it gently.

2. Its construction is more common in the current ordinary housing, which replaces the original large white powder fiber slurry wall, and has the advantages of low cost, fast construction speed and easy repair.

3, scrape the white generally 2-3 yuan a square, now generally two people, if there is a simple modeling and gypsum line labor cost of 12-15 yuan a square meter or so, depending on the construction difficulty of the site, if there is no gypsum line to simply install the yang angle and then once the gypsum twice putty 10 yuan a square meter.

There are a few main reasons for wall peeling:

Temperature change: Excessive temperature causes water-soluble salts to crystallize on the surface of the wall, causing peeling and peeling. In addition, the use of air conditioning causes the temperature difference between indoor and outdoor, which leads to the expansion or contraction of the wall surface, and also causes the local wall to peel off.

Wall dampness: In the rainy season, the wall is damp due to high air moisture, and the moisture penetrates into the paint surface and causes the paint film to lose its adhesion, resulting in peeling and peeling.

Mold on the wall: Mold and fungus can cause green or black mold spots and spots on the wall, which has a great impact on the overall appearance of the wall and also endangers the health of the people who live in the house.

Specific workarounds:

Dealing with old walls: If it is a partial peeling, then remove the peeling part and re-scrape the putty in a small area.

Reinforcement of 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 substrate with a reinforcing agent, and then carry out a series of steps such as plaster leveling, pasting mesh cloth, and brushing primer topcoat.

Direct brushing topcoat covering: After the survey, if there is no chalking or peeling phenomenon, for the place where the peeling is not very serious, you can directly apply the topcoat to cover.

1. The putty is not dried before the latex paint is constructed, so you must not be in a hurry when the wall is constructed, and you must wait for the putty to dry before you can start the construction of the latex paint.

2. After the construction of the first latex paint before the surface is dry, the next latex paint will be constructed, so the construction should be carried out in strict accordance with the construction instructions of the latex paint during construction, which can avoid such problems.

3. There are wax, oil and other substances on the wall, which reduces the adhesion of latex paint, and cleans up impurities such as wax and oil stains before construction, and strictly follows the construction instructions of latex paint to avoid such problems.

4. For the quality problem of latex paint itself, choose latex paint of high brand quality (such as Dulux) and strictly follow the construction instructions of latex paint to avoid such problems.

5. There are many reasons for peeling and peeling off the wall of the old house, such as: bubbles caused by water leakage, aging of the wall skin, etc., when encountering such problems, you can do local repairs, and paint latex paint, but this can not fundamentally solve the problem, in order to fundamentally solve such problems, it is recommended to shovel off all the old walls and then re-construct.

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!

The cause of peeling and peeling on 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.

For construction on the smooth surface of concrete and wooden boards, a layer of adhesive (tile adhesive) needs to be rolled on, 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.

This is a good treatment, tools, a roller, a gray knife, 240 sand skin 3 sheets, a sand frame, 2 bags of putty powder material, 5 kg of latex paint, steps, use a roller to add water to roll the wall first, and then use a gray knife to shovel off the wall skin, and then use putty powder and water to batch the wall, and after drying, put the sand skin on the sand frame to polish it, and then use the roller to roll the latex paint on the OK.

1. If the white wall part is bulging or slightly peeling, the peeling place should be cleared first, and the edge of the cleared part should be polished and smoothed, and the putty should be scraped once, primer, and then brushed. However, there may be a certain color difference from the original wall. 2. For the relatively serious situation of partial peeling, it is necessary to consider whether it is good to treat the base layer of the Zhengsou.

Clean the original wall to the base layer, re-brush it with interface agent or sealing primer 1 time, and then grind it according to the plaster leveling, paste the mesh cloth, and scrape the wall lining 3 times, and the overall quality of the base will be much better.

If there is no chalking or falling off, it means that the original putty layer is of good quality, and it can be directly smoothed with fine sandpaper and then refreshed after the topcoat can be refreshed.

2. Re-construction is equivalent to re-decoration, with a large amount of work and is suitable for many peeling walls. Remove the walls to the cement layer first, and if some houses have not been renovated for a long time (e.g. before the 80s), remove them to the brick walls, and then renovate the walls.

3. If there are large cracks in the wall, fill them with mortar first, and then smooth them out.

1. For the position of the top of the wall, directly use the plaster shovel to clean the external wall skin and putty, scrape the putty again after processing, and brush a layer of latex paint after drying. 2. First wet the place where the skin is peeled on the top of the wall to avoid large dust when rubbing, then use small things to knock out the small hole in the peeling position, and then use a plaster shovel to scrape the entire putty of the peeling wall, then spray a layer of water, then brush a thin layer of putty, and finally apply a layer of latex paint.

1. When the roof is peeled, use a plastering knife to shovel down the exterior wall skin, and then wait for the putty to be completely dry and start to brush the latex paint, wait for the moisture to be dissipated, and the wall will not peel after a period of time after drying. For the case of wall peeling, we must pay more attention to the rigor of the construction process when decorating, and the painting of the wall should wait for the previous process to be completely dry before the next process, which can greatly reduce the appearance of wall problems.

2. For wall decoration, the choice of materials is also more important, the putty should be brushed with less alkali putty material, which can prevent the wall from being alkaline, and the waterproof material should also choose a better one, which can greatly reduce the probability of the wall being damp and mildew.
