What causes blistering of car paint

The reasons for blistering of car paint are as follows:1. The quality of the paint is not good, and this problem often occurs in the roadside shops outside. These stores produce very low levels of paint** because they all use low-quality paint.

These paints are sprayed on the car, and the quality can be imagined.

2. The construction conditions and processes are not rigorous, and the construction conditions and processes of the coating are high. Before painting, it is forbidden to have any moisture on the surface of the paint. Previously, the filler ash (putty) of the paint surface had to be thoroughly dried in a dry environment before it could enter the paint booth for painting.

The air hose connected to the painting gun must be kept dry and no moisture is allowed. The above points are also important reasons for the blistering of automobile paint.

3. If the paint is sprayed too thickly, the spraying layer of the paint is not paid more attention or the technology of the construction personnel is limited, it will often lead to the overall thickness of the paint being too thick and the paint body flowing down. In addition, if the post-grinding treatment is not good, bubbles will appear on the paint surface in the future.

The cause of blistering of car paint is that the paint quality is not very good, and the paint is uneven. The quality of the paint is not very good, this kind of situation often occurs in the street shop outside, this kind of shop usually spray paint is very low, because they are not very good quality of paint, there may be some problems after painting.

Solution to blistering of car paintIf the paint on the car is blistered, you need to go to a professional repair shop or 4S shop to find a professional repairman to repair it. The causes of paint blistering are complex. Generally speaking, the paint surface can only be repainted after it has been blistered.

If the blisters are small, you can spot apply them with the same type of paint, and the blisters range are large, so you can only choose to recoat.

In addition to the role of wax, the sealing glaze can increase the strength of the paint and prevent small scratches caused by wind and sand on the body. The retention time is relatively long, which can be up to about 3 to 4 months. The sealing glaze ** launched by the car beauty shop is basically done in years and in several times.

If the paint on the car is blistered, you need to go to a professional repair shop or 4S shop to find a professional repairer to repair it.

The reason for the blistering of car paint may be affected by the poor quality of the paint, most of the time, after the car is repaired with poor quality paint, after a period of time, the paint will change, and this situation often needs to be repainted.

It is also possible that when the car is painted, the repair personnel's skills are not exquisite or the construction process is not rigorous, the construction conditions and technology of the car paint are very demanding, the painting needs to be carried out in a dry environment before, the air duct connected to the spray gun for painting must be kept dry, and it can not be mixed with water, if the doped water may cause the car paint to blister.

If the paint is sprayed too thick, it will often affect the overall thickness of the paint is too thick, and the paint body will be indecent.

Daily maintenance of car paint.

1. Car washing should be regular, it is wrong to wash the car all by rain, the impact of rain on the paint is superimposed, there may not be much feeling at first, and the paint damage will be accelerated after a long time. The correct way to do this is to rinse your car after the rain and wipe it clean.

2. Waxing, glazing, coating and other paint beauty items can effectively protect the car paint.

3. If it is stained with asphalt, bird droppings, chewing gum, etc., it must be cleaned up in time, otherwise it will further corrode the car paint.

Cause analysis: After the dissection and analysis of the blistering part of the topcoat, the blistering layer is all above the middle coating. Only the topcoat film blistered, and the middle coating did not find any blistering.

The main reason is that the sealing ability of the primer is relatively poor, even if there is water vapor in the primer and primer film, it can volatilize through the micropores of the paint film. The paint film of the topcoat layer is relatively closed, especially after the complete reaction of the two-component paint, if the paint film contains water vapor, it cannot volatilize, and the topcoat film is locally stressed and produces bubbling phenomenon due to the action of weather temperature and bottom water vapor expansion.

The seasonality of producing rice grain bubbles is more obvious, and most of them occur.

In July and August, it is rainy and humid, and because the air contains a lot of moisture during this season, even in the paint booth, sometimes the humidity is greater than 70. When spraying paint, sometimes the surface of the coated object is ground by water, it is difficult to volatilize the water completely, if the paint is sprayed on the surface containing water, due to the relatively small amount of water vapor, it is distributed in a fog on the surface of the object. In the process of paint covering and film formation, water vapor can volatilize away with the volatilization of solvent, after drying, the paint film is closed to the water vapor, and the water vapor left under the paint film encounters climate change, and the water vapor at the lower part of the paint film expands, and the paint film will be jacked up, and the paint bubble is formed, which generally takes 3-5 days.

The coating needs to be sanded, all solvent bubbles removed, and reapplied.

There are many reasons for blistering, first of all, the putty scraped on the car is not completely dry and hurriedly sprayed with paint, and the iron plate of the car is broken when making sheet metal, and the putty is scraped without welding in time is also the cause of blistering. There are many reasons that will cause blistering, such as the poor quality of putty, or the air is too humid when spraying, the paint ratio is incorrect, and the place to be sprayed is not covered with insignificant corners when spraying.

It is preliminarily inferred that the cause of the aging of the paint surface is related to the paint used in the car. You can find the manufacturer, now the coating of the car is guaranteed to be more than 5 years without problems, can only be re-sprayed, if the area is small, you can spray locally. Depending on the size of your body and the quality of the paint, the cost of materials ranges from 7800 to 15600 yuan.

Imported paint is still much stronger than domestic paint.

There may be many reasons for blistering, which are generally due to the quality of their own paint, spraying process, and aging. After blistering, it is generally necessary to deal with it, and re-paint after taking care of it, and if the blistering is small, it can be temporarily coated with the same color and type of paint to avoid affecting the iron layer.

Hello car owner, this needs to be sanded off and repainted.

Blistering of car paint can be caused by poor paint quality or improper repair of car paint. Slight blistering of car paint needs to be treated, car paint blisters will not disappear on their own, after the owner finds out, must not be ignored, need to be dealt with in time, otherwise the consequences are very serious.

The blistering of car paint itself does not disappear, and the reason for the blistering may be that the paint quality is not good, and there may be some problems after spraying.

In addition, painting requires a good construction environment and certain technology, and there can be a little water before painting; Before painting, the paint surface needs to be filled with putty, and then thoroughly dried in a dry environment before entering the spraying room for painting; The air hose attached to the paint gun must be kept dry and not exposed to moisture, as this may cause the paint to blister.

Slight blistering of the paint needs to be dealt with promptly. First of all, blistering can affect the appearance. If you don't pay attention, after a while, the paint may crack, and then there will be rainwater seeping into the internal metal rust, which will then expand the damaged area and damage the body.

Therefore, once you find that the car paint is blistered, you should go to a professional repair shop or 4S shop to find a professional repairer, if the blistering area is large, you should choose to repaint.

Paint bubble is one of the manifestations of paint damage, unfortunately, car paint bubble does not have too many good treatment methods, if the blistering is less, you can choose to use the same color paint point, but that is just a rainy day, if the body part of the blistering phenomenon, then the best treatment can only do car paint, otherwise it will affect the beauty of the body.

In this case, there will definitely be car owners who ask, since the consequences of car paint blistering are so serious, what is the reason? The causes of automotive paint blistering are complex, but a few common ones are paint quality and construction process. Because this aspect of the factors can not be controlled by the owner, so we can only do paint maintenance, in order to avoid or slow down the possibility of car paint blistering, the car wash should be timed, full rain washing is wrong, rain superimposed on the car paint, at first may not feel too much, a long time will accelerate the damage of the car paint.

The right thing to do is to wash the car after the rain and wipe it clean. It can be waxed, glazed, painted and other paint beauty products can effectively protect the car paint.

It may be that the quality is relatively poor, it may be that it is thicker when spraying paint, or it may be that the technology is not up to standard; No, you can't leave it alone, you must do a good job of partial repairs.

Because your car is often exposed to rain, it will blister. If you don't leave it alone, the car will rust and affect the aesthetics of the car.

The quality of car paint is not good. No, if this happens, you must repair the car immediately.

Hello, the primer is not treated well or has oil stains.

It's usually rusty, and it's rusted from the inside, so let's go and see it.

This should not be the case with the original paint, whether yours has been sprayed or on the hood. That is, the paint is not sprayed well, and the bubbles baked by the engine heat.

Paint the back of your car. At that time, the paint was not used well, or the construction was not professional, and the paint would blister and peel off within two years. It is recommended to respray or try the body color change film.

There are many reasons for blistering, first of all, the putty scraped on the car is caused by the rush to spray paint before it is completely dry! In addition, the iron plate of the car was broken when making sheet metal, and scraping putty without welding in time was also the cause of blistering! In addition, the primer that you spray before you spray the topcoat will cause blistering if it is not cleaned or reacts!

There are many reasons that can cause blistering, such as the poor quality of putty, or the air is too humid when painting, the ratio of paint is incorrect, and the place to be sprayed is not covered completely exposed to the insignificant corners, many, many reasons.

There could be several reasons for this:

The first is that the construction environment is not good, the airtight is not good, and there is water mist falling on the surface of the paint during the construction process;

The second is that there is a problem with the oil-water separator, and there is water in the spray gun;

The third is that the paint is misted during the drying process.

If it can be solved by polishing after painting, it needs to be re-sprayed if it can't be solved by polishing.

The causes of car paint bubbles are:

1. The paint quality is not good.

This kind of problem often occurs in the roadside shops outside, and the paint in this kind of shop is often very low, because they also use low-quality paint, and the quality of these paints sprayed on the car can be imagined.

2. The construction conditions and process are not rigorous.

The construction conditions and technology of the paint are very demanding, and it is strictly forbidden to have the slightest moisture on the paint surface before painting; The paint filling ash (putty ash) in the early stage needs to be thoroughly dried in a dry environment before entering the paint room for painting; The air duct connected to the spray gun for painting must be kept dry and does not allow the slightest moisture, which is also an important reason for the blistering of the car paint.

3. The paint is sprayed too thickly.

The spraying of the paint layer is not paid much attention or the technical limitations of the construction personnel often lead to the overall thickness of the paint is too thick and the paint body is downstream, and the later polishing is not handled well, which will also lay the groundwork for the future paint blistering.
