What are the causes of latex paint peeling, wrinkling and cracking? How to prevent latex paint from

The decoration of our interior walls can be roughly divided into three situations. The first case is the application of latex paint on the walls. The second case is the wallpaper on the walls.

The third case is the tiles attached to the walls. At this stage, our living room, bedroom, study and other locations are the same as most of the walls, mainly latex paint. However, poor construction of latex paint will produce slight cracks, bites, etc., therefore, the family miscellaneous group would like to introduce the specific construction process of indoor wall latex paint in detail in this article, and how to prevent some problems in the construction quality of latex paint.

The feeling of scratches on the walls of our interior has been fully completed and reached the corresponding strength. In this case, it is necessary to scrape at least 7 days or more, and the greasy things on the wall have been polished by abrasion, and some of the dust on the greasy surface has been cleaned. We have selected the corresponding paint according to the requirements of our home decoration design.

In particular, some special color paints have been matched accordingly. The corresponding construction tools are prepared, and the construction conditions are available, and the interior latex paint can be painted. We need to understand the overall construction process of latex paint engineering.

In fact, it boils down to four words, that is, two sides. The so-called bottom two sides are the bottom primer once, and the two sides are painted twice.

We need to know the approximate sequence of the latex paint construction process on both sides of the first floor. When applying the primer, the grease of the wall has already been treated. I painted it twice.

It's all done on the primer. Therefore, we should pay attention to the painting works at all stages. Cracks caused by seasonal climate change are normal, and there are many seams between the ceiling line and the door frame in general, so this situation goes without saying.

But if it's because you didn't pay attention to the temperature while painting, it's not normal. The paint temperature of latex paint is also one of the key factors for not breaking, and the surrounding environment is best from 5 to 35 when painting. At this temperature, the envelope is good and it is not easy to crack.

In this case, think about whether the walls are damp or not! Like the wall near the bathroom, the waterproofing is not good, and moisture can penetrate the outdoors and make the walls damp. To consider the paint itself, the paint nowadays is generally water-based, so pay attention to the proportion of moisture added.

Otherwise, it will reduce the adhesion of the paint, and it will be easy to peel off later. If the base layer is handled well and not cleaned, it may be eliminated because it is greasy and the base layer does not adhere well. Alternatively, if the paint is painted without the primer drying, it will also affect the paint effect of the entire latex paint.

Before construction, the base layer of the wall is alkaline, or the direct light is received for a long time during the construction process, or the indoor ventilation is not smooth during the construction, and the wall may change color and yellow.

1.The construction temperature is too low. It cannot reach the film-forming temperature of latex paint and cannot form a continuous coating film.

2.Improper treatment of the base layer: such as cracking of the coating film caused by cracking of the wall.

3.The second coat is applied when the first coating is too thick and not completely dry, which causes cracking of the coating film due to the difference in the drying speed of the inside and outside.

4.The cracking of the cement putty scraped in batches causes the cracking of the coating film The solution to the peeling and cracking of the wall: 1. Peeling and cracking of the small area of the skin. Shovel off the peeled part and the surrounding wall skin, and patch it with the same color paint.

This reason is usually caused by drying too quickly after brushing latex paint, and it is best to avoid spring and autumn to prevent peeling, because the air is dry during these two seasons.

1. Because of moisture.

For example, the wall near the bathroom may not be waterproof, causing moisture to penetrate into the outside, which will cause the wall to become damp and peeling.

2. The reason for the paint itself.

Nowadays, the paint is generally water-based, so it is necessary to pay attention to the addition of too much water when proportioning, otherwise the adhesion of the paint will be reduced, and it will be easy to peel off in the future, which is also one of the important reasons for the peeling of latex paint.

3. The grassroots level has not been dealt with well.

If the base layer is not cleaned before applying the latex paint, it will cause the putty and the base layer to adhere poorly and form a falling off; Or the topcoat is applied before the primer is dry, which will also affect the application effect of the entire latex paint.

In the renovation, due to various reasons, there will be various problems after the wall decoration, such as:Latex paintCracking, peeling, etc., what are the causes of wall latex paint peeling (bursting) and cracking? The old house was renovated, the original wall putty ***, on which a thin layer of putty was scraped again, brushed with latex paint, and a year later, there was a burst of skin, and now it is getting more and more powerful. There are several main reasons:

Listening to the subject's own statement, the subject is the renovation of the old wall in his own home, and the quality of his original wall putty is very good. A layer of thin putty was re-approved, and the latex paint began to burst after a year, almost two years, and it is getting more and more powerful, how can it be better handled at a smaller price? Fourth, there is a hidden danger of moisture infiltration in the wall, and the living environment of the space also affects the wall.

For example, sun, rain, heat expansion and cold contraction.

Wait too fast, <>

The newly renovated living room, not lived for a long time, the wall peeling, chalking, falling off, will definitely bring a lot of trouble to the owner, will complain that the paint is not good, or the construction workers are sloppy. However, you may not know that in fact, the root cause of wall peeling, chalking, and peeling off is not the surface coating and construction level, but how to deal with the base layer during construction. In such a situation, the original paint film is too thin, and there is no strong grip on the base putty.

And the putty is scraped directly on the original paint surface.

The moisture of the putty will also cause a certain degree of damage to the original paint surface. Refresh service: The general formal process will provide full shovel and full batch service and partial eradication service.

Even if you think the original putty layer is okay, you should brush the old wall with glue or a primer such as reinforcement sealing, and then scrape the new putty powder.

Here you need to remind you that the wall is generally wet and will fall off after a few minutes, because the latex paint will oxidize after a few years, which may be due to poor paint quality and weak adhesion, resulting in easy to fall off. It is possible that you have not applied the primer and the adhesion is not strong. It is possible that the base layer has not dried and the topcoat has been brushed, and the latex paint wall will peel off due to moisture.

It may be that the brush is too thick, or the quality of the paint is not very good, you can change the product to a thin layer of brush to try.

It is very likely that the latex paint is opened for ventilation after the emulsion paint is brushed, resulting in the cracking of the latex paint wall skin, or it is possible that the putty is not scraped well, resulting in uneven wall surface, so that the thickness of the paint is uneven, or it is also possible that the quality of the latex paint is not very good, or the brush is too thick, which will lead to bursting skin.

It may be because there is too much dust accumulation, or the brush is too thick, or it may be because the quality of the latex paint is not very good, or it is not sanded when it is refurbished.

First of all, this is a very normal reason, because if you stay for a long time, then this will definitely happen. But I think the reason for this is that the temperature in the house is too high. Therefore, we must pay attention to this kind of problem in ordinary times.

Summary. Will latex paint peel Latex paint peeling off is actually a very common phenomenon, and the reasons for falling off are: The problem of the contact surface of the base layer:

When the latex paint is applied, the wall is not clean, the workers are lazy, and the wall is not polished and cleaned, resulting in the adhesion of the latex paint is not strong; Weather or environmental problems: during construction or use, long-term exposure to humid environment, resulting in excess moisture in latex paint, when the wind blows or when the weather is dry, latex paint will shrink and tighten, causing peeling. The former phenomenon.

Wall cause: Although your wall is a new wall, it does not exclude this reason, the wall is not good, and it will also cause the surface to crack and fall off. Latex paint product reason:

Don't say much about this reason, you choose not good paint, fake and shoddy products or brands with poor qualifications.

Reason for latex paint products: Don't say much about this reason, you choose not good paint, fake and shoddy products or brands with poor qualifications.

After priming, why does spraying latex paint still peel.

I bought latex paint from a specialty store.

Causes of pro-latex paint primer crusting: the reason for the estimation of latex paint primer is poor quality, poor adhesion, or wrong mixing ratio debugging; The cleaning and leveling of the wall is not in place; The dust is too big and not cleaned, and the brush is too thick; Long-term exposure to humid environment during construction leads to excess moisture in latex paint. Here's why:

Clause. First, the quality problem of latex paint itself may be due to the poor quality and poor adhesion of the purchased paint products, or it may be due to the wrong debugging of the mixing ratio. This requires everyone to do an inspection of the latex paint to see the actual situation. Second, look at the situation of your own wall, if the cleaning and leveling of the wall is not in place, resulting in impurities on the wall and latex paint peeling.

Thirdly, the dust is too big and not cleaned, the brush is too thick, or the paint quality is not good, and it may also be that there are oily things on the old surface. The renovation of the old wall needs to be polished, and it does not need to be shoveled off, just sweep away the dust, and if there is a greasy or dirty layer, it will be partially polished off. Fourth, weather or environmental issues.

During construction or use, long-term exposure to a humid environment leads to excess moisture in latex paint, and when the wind blows or the weather is dry, the latex paint will shrink and tighten, resulting in peeling. For the former phenomenon, it is better to consult during construction, and in the latter case, for example, to brush latex paint in the bathroom, you had better choose waterproof latex paint.

Summary. Related information: 1. Before the construction of latex paint, it is necessary to check the base layer of the wall, if there is unevenness, it is necessary to do the leveling work first, and then clean the wall after processing, and then clean the wall, and there shall be no more stains or dust, otherwise it will affect the later painting effect, peeling, falling off and other phenomena.

2. Before the construction of the wall, it is also necessary to see whether the wall meets the construction standards. You must know that before the wall is painted with latex paint, it must be dry, otherwise it will affect the construction effect. Generally speaking, the wall needs to be kept dry for about two weeks, and the moisture content is reduced to less than 10% before construction.

3. Before the latex paint is not used, it needs to be placed in the area where the sun does not shine and the rain cannot be wet, so as to avoid the problem of the quality of the latex paint and affect the later painting. Moreover, during construction, the water content added should be added strictly according to the instructions, so as not to have too much or too little water and reduce the quality of the coating. 4. The construction of latex paint should also make the surrounding temperature meet certain conditions.

If the indoor temperature is below 5 degrees, it is not possible to carry out construction, which will affect the quality of the paint. If the temperature is too low, you can choose to turn on the indoor heater and raise the temperature before construction.

Hello, I am honored to answer for you: 1. What is the reason for the peeling of latex paint 1. Before the construction of latex paint, the dust on the wall is not cleaned up, or there is unevenness. 2. When painting latex paint, the humidity of the wall is large, which affects the quality of latex paint.

3. When the wall is new, it is directly brushed with latex paint without treatment. 4. There are problems with the quality of latex paint, resulting in poor painting effect.
