What should I do if the computer is painted? What to do if the lacquered table top is peeled

Paint peeling and how to solve it:

1. The batch of putty is not dry.

If the second coat is applied before the first coat dries, it is easy for the paint to peel.

Solution: Remove the old paint by scraping and sanding, then apply an acrylic primer. Allow to dry completely and reapply with indoor acrylic paint.

2. Caused by moisture.

If the paint is left in a humid environment for a long time, it is very easy to peel, crack, and peel.

Solution: First of all, solve the problem of wall leakage and let the wall be fully dry, and remove the peeling and peeling layer for normal surface treatment.

Post-paint. 3. There is no primer brushing.

If there is no primer, then the paint and the base layer can not be well bonded, the adhesion of the paint is very bad, and it is easy to peel off and fall off.

4. Inferior primer.

Paint inferior primer with very poor performance during the rainy season.

If the economic conditions allow, simply upgrade and replace.

The paint door, that is, the dust-free paint baking process carried out outside the door panel, is the paint door that is painted through the paint after spraying and entering the drying room for heating and drying process. At present, the vast majority of paint-free doors on the market refer to PVC veneer doors. It is made of PVC veneer vacuum blister processing technology for the outermost part of the solid wood composite door or molded door.

Its advantages are bright color, strong visual impact, good surface finish, easy scrubbing, moisture-proof and fireproof performance. The types of high-grade PU paint doors are divided into piano paint and metal paint, and metal paint is better than piano paint.

The advantages of the paint board: it is very beautiful and fashionable and has excellent waterproof performance, strong anti-fouling ability, and is easy to clean. It is more suitable for young high-end consumers who have high requirements for appearance and quality, and pursue fashion.

The disadvantages of the paint board: the process level is high, the rejection rate is high, so the highest level; It should also be carefully cared for when used, and it is relatively afraid of bumps and scratches, and once it is damaged, it is more difficult to repair it professionally. At the same time, because the quality of the surface paint is difficult to distinguish, if you claim to be a high-grade PU paint, but the ** is very low, it can be judged that it is almost impossible to use high-grade environmentally friendly paint.

When you have the feeling of using a low-grade paint door, you will find that under the pollution of oil smoke, it may change color after a short time, and the luster will gradually disappear. Although the painted door panel is beautiful, if you use inferior paint, it will definitely peel in the corners after a long time, especially in the north, where the temperature difference is large and the climate is dry, which is inevitable.

Repair of lacquered doors:

The paint-free door cannot be repaired, and the color of the paint-free door is like how to repair our ** color.

His color is not lacquered, it is added when making the plywood, and the outermost layer is a layer of PVC plastic film, if this film is damaged, it can only be sent back to the factory and wrapped back, and the paint door can grind off all the paint and then paint.

If you just open a slit, you can use a watercolor pen of a similar color to trace it. If it is too big, you can find a paint-free leather with a similar color and paste it with all-purpose adhesive.

One is to clean the peeling part and repair the paint or spray paint the whole surface, and then buy a waterproof, colored tablecloth to cover it.

Peel the peeling part with sandpaper, and then buy some self-spraying paint with the same color and spray it yourself.

Clause. 1. Find a professional repair company to repair.

Clause. Second, the overall paint film grinding, buy some Xingguo water-based wood putty to scrape off the peeling part, use wood putty to grind flat, brush Xingguo water-based wood paint, the overall effect is not as good as the paint, but expensive in the construction is simple to save money, environmental protection, etc., related products can go to the Xingguo water paint workshop to see, for your reference.

There are many reasons for paint cracking, and the paint is most taboo to be painted on damp walls, which will undergo chemical changes after being wet, which is also the main reason why many new houses often have paint peeling and peeling. Therefore, it is best to wait until the walls are completely dry before applying paint. If the paint surface has fallen off, you can scrape off the falling part with a putty knife, and then use cellulose putty or paint and gypsum powder naughty putty to flatten the unevenness and pits, and smooth it with sandpaper after drying, and then paint it.

It is advisable to be thin when brushing, you can brush several times, and you should wait for the previous time to dry before brushing.

First of all, the old wall should be surface treated before painting. Because the old wall has been stained and pulverized to varying degrees, directly painting on the surface of the old wall will not only affect the smooth effect of the appearance, but also produce isolation and pores at the interface of the two paints.

Secondly, the paint layer we paint should not be too thick, because when the paint film is thick to a certain extent, the flexibility of the paint film will be reduced and brittle, and finally the paint will be peeled.

Finally, in order to increase the adhesion of the paint, we can first treat the substrate, then apply a layer of primer and then coat it. Jiangsu Geelong Paint has professional engineers, you can go to consult about the paint questions.

The biggest reason for the peeling of the wall is that the moisture content of the wall is too high, the moisture seeps out, condenses in the paint film, causing peeling, the base layer is not closed, and the paint film should be scraped off and repainted.

Peeling is caused by moisture! And it's a leak in the bathroom! Throw the tiles at the bathroom door, throw them to the waterproof layer, and then increase the cement mark and re-grout! That's it! After processing, it must be re-hung in the peeling place!

The specific situation depends on the change of the field, but the logarithm of this case is. Reason 1: The waterproof layer of the bathroom is not done thoroughly, causing the water to accumulate on the ground or wall after showering and slowly penetrate into the opposite wall, and the second reason is that the heat pipe of the toilet water pipe is damaged due to the continuous alternation of cold and heat at the elbow after being used for a period of time. Leakage is caused, which affects the corresponding wall.

Peeling is definitely caused by moisture. The problem lies in the handling of the basics, and it is difficult to say on what basis. First, check your walls and windows for water seepage.

In addition, the standard construction of latex paint is generally one bottom and two sides. That is, one primer, two topcoats, the primer has good moisture-proof and mildew-proof properties, and the topcoat has good hiding power. Of course, in the general construction process, there are many construction methods that directly take the second topcoat, and there are generally no major problems.

The temperature of your room is definitely not high, almost all the paint should be applied above 10 degrees, especially the oil-based paint used for wood decoration, the temperature is best around 24 degrees, and a certain humidity should be maintained.

The causes of peeling and peeling of latex paint are as follows:

1. The humidity in the substrate is too high.

2. The surface treatment is not clean, resulting in poor adhesion of the coating.

3. Inferior primer is used.

Here's how to fix it:

1. Solve the problem of wall leakage and let the wall be fully dried.

2. Shovel off the peeling and peeling layers for normal surface treatment and coating.

3. Choose a matching primer.

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.

1. The peeling and peeling of the wall paint is mainly caused by the construction process, which can be dealt with according to the following methods.

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.

Answer 1: If the wall is damp and peeling due to rain, the peeling wall should be repaired and the interior should be dehumidified. If the peeling is severe, you need to shovel off the wall, treat the base layer, scrape putty, and brush the primer and topcoat.

2. Before the formal construction, it is necessary to check the firmness of the wall to ensure that the cement mortar on the wall is smooth and firm, so that the subsequent construction will be safer. If it is found to be loose after inspection, it needs to be replaced to avoid unnecessary leakage.

3. Before the formal construction of the wall, the surrounding wall should be protected, so that when applying putty and paint, it will not cause damage or scratch to the surrounding foreign objects. Scraping the wall or scraping the wall to repair it later requires more time and economy. During the drying process of the wall, try to open the window for ventilation and natural drying.

Do not turn on the air conditioner to speed up drying, so as not to cause cracking of the wall.

Preparation before putty: Before applying putty, check the flatness of the wall. When the wall is not smooth enough, it should be leveled, smoothed, and then painted with putty.

If the economic conditions allow, it is recommended to brush the RCC interface agent on the wall, and then start to apply putty powder after it is completely dry, so that the wall will be firmer and not easy to peel or peel off. When brushing putty, it is recommended to brush it twice as much as possible, and the interval between the two times should be longer, so as to ensure a better putty effect.

The peeling of the wall peels off, and according to your description, it is not excluded that there is a phenomenon of dampness and dampness. It has nothing to do with the previous wallpaper, it is recommended that you check whether the wall is damp, and find the specific cause in the maintenance is more critical.

If the wall is wet, it is necessary to remove the damp part of the original wall during maintenance, and then repair the cause of water seepage and repaint it in order to effectively avoid the same problem in the later stage.

If you install it yourself, see what causes the peeling, and then find a worker to prescribe the right remedy for the paint. If you are looking for a renovation agency, contact them directly.

It is necessary to remove it before it can be brushed with latex paint, otherwise it will definitely peel.

The peeling off of the wall is the problem of the wall base, and the original base layer needs to be removed and redone, and the specific steps are: shoveling the wall - interface agent - gypsum - putty twice - grinding - primer - topcoat twice.

The wall sprayed for 2 days, even the lacquer fell off together, the putty seller, the paint merchant did not admit the account, please ask which department to find me to be fair.

1.The base layer of the ground is not done correctly, so that the paint and the base layer can not be well bonded, or the base layer is not firm, and the base layer falls off directlyThe ratio of lacquer is not right 3

Before the time of use, early use, improper maintenance (generally unlikely to have such a problem) Anyway, basically, there are not too many human factors, mainly focusing on the problem of the base layer and the paint itself.

In the final analysis, the decisive factor of coating (paint) peeling is mainly the influence of the base layer, and the quality of the coating itself, such as the anti-aging performance of film-forming substances, will also be one of the reasons, but qualified products generally do not have a similar situation! The coating process of shipbuilding you mentioned is no exception, the anti-rust treatment of steel plate is the key, local cracking, oxidation, corrosion and other effects are the key factors that constitute the peeling, peeling and cracking of the finishing paint!

I.1The reason for the peeling of car paint is mainly related to the painting process, the method of spraying primer is improper, and the thinner used is of the wrong type or poor quality. The bottom surface is not well treated and is polluted by wax, grease, water, and rust.

No metal surface treatment agent is used on the surface of steel or aluminum, or the type of treatment agent used is incorrect.

2.The other reason for peeling of car paint is that the surface temperature of the substrate is too high or too low and the pressure of the compressed air is too high when spraying. For the peeling of the car paint, it is necessary to grind off all the peeling areas and re-spray.

2. Measures to prevent peeling of car paint: 1. Thoroughly treat the surface of the substrate ready to be sprayed. 2. Be sure to use the correct metal surface treatment agent on the surface of steel or aluminum, and start spraying within 30 minutes after treatment to prevent rust on the surface of the substrate.

3. When spraying and drying, it should be guaranteed to be within the recommended temperature range. 4. Use the correct process to spray the primer to ensure that the primer layer is fully cured before spraying the topcoat. 5. Use the recommended diluent to dilute the paint to the required viscosity range.

6. The coating should be thin and wet each time. 7. Adjust the spraying pressure correctly.

Paint peeling is a common problem in decoration, mainly due to the soft and non-strength of the base layer, and the formation of "anti-grip" by the finishing coating! The paint surface is bursting, peeling, it is mainly due to improper foundation treatment, mixed with paint foundation treatment usually uses oily putty or putty, and many construction personnel in order to facilitate the construction of water-based putty, there will be no problem when handing over, and after a period of time due to the change of moisture and climate, the paint surface bursts, peeling. Strict control of the construction process and the concealed engineering of the construction process is the premise of ensuring quality.

The reason for peeling and peeling of wall paint.

1. There are problems such as oil stains and dust on the painted wall. Prevention: Clean the base layer before brushing the paint.

2. The surface of the coating film formed by the primer is too smooth, and the surface coating film cannot penetrate the substrate, and there is no good adhesion with the primer. Prevention method: Use the same brand and matching primer to paint.

3. The bonding strength of putty powder is too low, and the water will dissolve it when it penetrates into the base layer. Prevention method: Choose water-resistant putty powder with good strength as fan ash material.

4. The cohesion of the elastic coating film itself is strong, the permeability is worse than that of the general coating, and the coating film is prone to the phenomenon of peeling off the whole sheet. Prevention method: Choose the best elastic paint and brush the paint twice.
