How to remove shagreen after painting a car

Coarse shagreen (orange peel effect) can occur due to insufficiently diluted paint, a large spray gun nozzle, or rapid evaporation of the solvent from the paint.

To remove shagreen after painting, so-called deep abrasive polishing is required. The principle is that a thin layer of varnish is removed with sanding paper P1500 - P2000 using water. If the varnish is well dried, then dry sanding can be used using an eccentric sander and appropriate grinding wheels.

However, the first option is more common. With this method of sanding, the shagreen becomes less noticeable. If you continue sanding the varnish, you can achieve a completely flat surface, without shagreen, but the varnish layer will become significantly thinner, and this is not very good. Trying to completely remove shagreen, you risk rubbing the varnish down to the paint, which will be impossible to fix without repainting.

So, the freshly painted surface is sanded. There is also a point that for sanding it is better to use a hard flat block so that the sanding paper does not smooth out, but “cuts off” the tops of the shagreen. Next, you need to remove all remaining varnish particles from sanding with clean water. To smooth out scratches from P2000 sanding paper, you need to use an Abralon 2000 abrasive wheel, or a 3M Trizact 2000 or 3000 wheel. These abrasive wheels will smooth out the scratches and make the surface uniformly matte. The next step is to use an abrasive polishing paste. You can take 3M paste with a green cap, which replaces the outdated 3M pastes No. 1 and No. 2 (coarse and fine abrasive). It has a special composition and structure that can smooth out and almost completely remove remaining risks. You can read more about polishing in another article.

It is better to use this paste first with a dense circle and medium speed, and then use a circle of medium hardness and increase the speed. For cars with a dark paint color, you need to additionally use a polish that removes circular marks (holograms). 3M comes with this polish in a bottle with a blue cap. Polishing will restore the gloss and all that remains is to apply protective wax.

Reasons for appearance

Shagreen on a car can result from improper painting. And it arises for the following reasons:

The paint and varnish product was prepared according to the wrong recipe. As a result, the consistency turned out to be of low viscosity, which was not enough for uniform application on the surface of the car.
The paint manufacturer's instructions were not followed correctly. The wrong solvent may have been used.
The spray gun has not been adjusted correctly, so the air pressure does not meet the required parameters.
The spray gun used a very large nozzle.
The conditions in the box where the car was painted were unfavorable. The air temperature is either higher or lower than normal, which is why shagreen appears when painting and other defects.
The car paint product was stored incorrectly (at low temperatures). When using such paint, it lies unevenly on the surface of the car.
The painted parts were not dried correctly and the drying times of the layers were not maintained.

Shagreen on a car can appear even if the car is painted in specialized services. In order to avoid its occurrence, it is necessary to take measures that prevent such a defect.

Required roughness

But there are situations when it is desirable or even necessary to achieve a shagreen effect on the surface to be painted. Walls decorated with shagreen leather look very aesthetically pleasing and attractive. This trend has become quite fashionable recently.

Shagreen effect created intentionally

In addition, using shagreen dyes you can hide some defects in walls and other surfaces. For example, welding seams, kinks, small depressions or local roughness can be easily decorated using shagreen paint. In this case, all defects become less noticeable and seem like an interesting design move. While when painting without shagreen, the irregularities will remain visible and will spoil the overall picture of the interior.

The most popular shagreen is considered to be polymer powder paint. The surface for which powder shagreen is used can be of any kind. This includes plastered or primed wall surfaces, and various pipes and communications.

Shagreen has good adhesion to metal surfaces. Therefore, the paint can be used to decorate doors, safes, as well as metal objects and equipment. In addition to its texture that is pleasing to the eye, shagreen paint has protective properties and is designed to protect surfaces from adverse environmental conditions.

What to do to prevent a defect from appearing

It is possible to paint a car without the appearance of defects, but to do this you will need to follow some rules and adhere to painting technologies.

It is also recommended to use only high-quality tools in your work, as well as use good paint and solvents.

Many masters highlight the basic requirements that help prevent the appearance of shagreen:

At the moment when the paint and varnish composition is mixed, the proportions should be strictly adhered to. In order for the proportion to be maintained with greater accuracy, it is necessary to use measuring containers for work.
A solvent should be used to paint the car and mix the paint. It must match the paint; as a rule, the manufacturer writes on the can which solvent should be used. You also need to know that the solvent is used not only according to the manufacturer’s recommendation, but also depending on the climate, room ventilation and volume of work.
Also, before painting, you should properly set up the spray gun. It should have a passport with data on pressure and other characteristics. Tool adjustments must be made after any use.
The temperature for painting a car indoors must meet certain indicators, namely about 20 degrees. A temperature discrepancy of 1 degree is allowed, both up and down.
Storage of paint and varnish compositions should not be in a humid place, and the temperature should correspond to the data in the paragraph above

It should be noted that shagreen is not so easy to remove from a car. In this regard, you need to be well prepared, since you will need to spend a little money and time.

Tips to prevent the effect from occurring

We can say that the effect of shagreen, or “orange peel”, is inherent in absolutely all painted surfaces. The only question is how noticeable this roughness is, and whether it is appropriate in a particular case. Most often it happens that they try to prevent or remove shagreen from the object being painted.

To do this, you need to pay special attention to the quality of the applied material and the manufacturer. Each layer, be it priming, varnishing or direct painting, must be done extremely carefully and accurately. Before use, you need to check and adjust all the tools used in the work.

Elimination of defects

As practice shows, shagreen is often obtained after painting a car. This is due to the fact that it is not possible to follow all the rules when performing the operation. To correct the situation, you have to resort to some methods:

In cases where the shagreen is small and insignificant, it is recommended to use the polishing method. Polishing should be carried out after the paint on the car has completely dried.

Then the shagreen will need to be removed using sandpaper. To work, you need water and the abrasive itself with a grit size of P1200 and P1500. When the main defect has been removed, you need to finish the polishing stage with P2000 and P2500 paper. After cleaning, you need to go over the parts with polishing paste to smooth the surface and give it shine.

If polish cannot remove defects from car parts, you should completely repaint them.

It is worth noting that when repainting, you need to remove all fresh paint and use sandpaper to smooth out and remove defects. After this, you can begin repainting.

Washing out

A number of other methods have been invented to eliminate varnish stains. Consider washout. You will need fine sandpaper (P2500 and P2000), putty, a vacuum cleaner and water. The treatment area is first thoroughly dried (an industrial hair dryer can be used). Then putty is applied to the stains. It will protect the varnish from damage. The putty layer is moistened with water and carefully polished with sandpaper (P2500). For a more accurate execution, you can wrap sandpaper around a flat block. Then they move on to fine sandpaper. This happens after the putty layer reaches the level. Work until the putty disappears. Final polishing again with P2500 sandpaper. At the end of the process, dust is sucked up with a vacuum cleaner and a layer of varnish is applied again.

What to do if shagreen appears when painting a car?

Shagreen after painting a car

Cases often occur when, after painting a car themselves, car enthusiasts violate an important technological sequence of operations or neglect special recommendations for the use of paint, which are in the manufacturer’s instructions.

The consequences of such actions are most often shagreen. The defect, which has been nicknamed "automotive cellulite", usually manifests itself in the poor merging of all the paint droplets on the surface. Although shagreen does not affect the integrity of the coating, it can seriously ruin its appearance.

How can you remove shagreen with your own hands? Is it possible to prevent such a defect from occurring in a garage? In this article we will try to consider in detail the main reasons for the appearance of shagreen after painting, and also tell you how to get rid of it.

Reasons for the appearance of shagreen

After painting both the car as a whole and its individual parts, shagreen may occur for the following reasons:

The coloring agent was made using the wrong recipe. The result is a low viscosity value, which is not sufficient for uniform application of the layer over the entire painted surface of the car.
Failure to follow the manufacturer's recommendations during the manufacture of the coloring agent. The result is the addition of the wrong thinner to the paint (more harsh for such a mixture).
Incorrect adjustment of the spray gun used. The result is either too low or too high air pressure.
Using a fairly large nozzle for the spray gun. In this case, defects may appear precisely because the resulting coloring composition is splashed over the entire surface and is not sprayed as necessary.
Unfavorable microclimate in the working paint booth. Low or high temperatures can cause various defects during painting, including shagreen.
Failure to comply with the storage conditions of the coloring agent used. When using paint that was stored in a room with a particularly low temperature, the mixture in this case does not spread well over the surface of the car being painted.
The required time and technology for drying the entire coating between the application of successive layers or in the case of using the air flow of a paint gun were not maintained.
Shagreen also occurs when painting in specialized automotive services. In order to prevent the occurrence of a defect, it is necessary to know the measures that will avoid its occurrence.

What is shagreen and why can it form?

Shagreen is an uneven surface of the body, popularly called “orange peel” for its visual and tactile similarity. It occurs when paint droplets do not completely merge after they hit the surface to be painted. It is not considered a disadvantage of the car, since it does not carry any bad consequences, but it noticeably spoils the appearance of the car.

There are many possible causes of shagreen, the most common of which are:

violation of the temperature regime in the box - painting work at low or too high temperatures;
using a spray gun that is too large a nozzle - in this case, the paint simply splashes on the sides in drops, instead of lying in an even layer on the surface;
mismatch between paint and solvent - the solvent should always be used only in the manner recommended by the paint manufacturer, otherwise shagreen cannot be avoided;
violation of painting technology - when painting in several layers, each of them must be completely dried, if this recommendation is ignored, “orange peel” cannot be avoided;
use of low-quality liquids (paint, solvent) or violation of their storage conditions;
Improper adjustment of the spray gun/gun - when it supplies insufficient or too much pressure.

How to prevent shagreen from appearing?

It is possible to paint a car without causing any defects if all established technologies are followed, as well as using the highest quality tools and materials. Experienced experts advise additionally following tips that will allow you to paint your car efficiently and prevent shagreen from occurring:

When mixing coloring agents, only the recommended proportions should be used, and measurements will be accurate if you use measuring containers.
The solvent must be selected in accordance with the manufacturer’s recommendations, as well as taking into account ventilation and climatic factors and the volume of work.
Correct adjustment of the spray gun, which is carried out according to the pressure indicators and characteristics specified in the personal passport for the product. The spray gun must be adjusted after each use.
It is necessary to establish and maintain a favorable temperature in the paint booth. The air in the box should be from +19°C to +21°C.
The place where varnishes and paints are stored should have a completely favorable microclimate. The air should be from +19°C to +21°C.

Removing shagreen and other defects after dyeing is the most labor-intensive and also costly process, in contrast to following the described recommendations and requirements.

Advantages and disadvantages of the method

If the paintwork is only slightly damaged, many people try to avoid an expensive painting procedure.

In addition, this procedure can be carried out on your own by purchasing the appropriate cans of paint. It is important to carry out the procedure in the appropriate room and in compliance with all technologies.

Before that, you can evaluate all the advantages of this method:

To carry out such painting, no special skills or preparation are required;
using a spray can you can carry out high-quality repairs;
any surfaces are covered, hard-to-reach places and bends are much easier to paint; no additional components in the form of a roller, spray gun, etc. are required during the work;
if you have no experience in painting, you will be able to apply an even layer of paint;
to apply an even layer you do not need to work with a roller or brushes;
Spray painting will cost less than other means; this service is available to many motorists.

However, it is necessary to realize that all painting methods have their own nuances and disadvantages.

Spray painting is no exception to this issue, so be prepared for the following disadvantages:

there are no detailed instructions on the rams for painting;
Sometimes you come across cylinders of poor quality, so before applying to a car, test on another surface;
Sometimes the declared shade and the real one may differ, so you should immediately purchase the required amount.

Select the color scheme in accordance with the labeling, but if you are still not sure of your choice, then you should consult with the experts in their field.

He will be able to carry out tinting using special equipment.

If the depth of the chip or scratch is insignificant, then it is not necessary to resort to painting; you can polish it.

If primer or metal is visible in the damaged area, then the work will be more serious and eliminating the defect will take longer, as will painting the damaged part of the body.

Spray painting a car is a step-by-step procedure that is ideal for doing it yourself, which allows you to save money at the same time.

This method is suitable for working with a small area of damage, but if the problems are serious, then contacting a service station cannot be avoided. All work will be carried out there in a special box.

How can you eliminate shagreen?

Unfortunately, it is often not possible to carry out all car painting work at the required level. The result of this can be various painting defects, including shagreen. How can you remove defects after painting a car?

Surface polishing

After the paint has dried, you need to clean the entire defective area using absolutely any abrasive material (for example, sandpaper). The abrasive depends mainly on the degree of damage to the car's surface. Polishing is the final process of getting rid of a defect; it creates shine and gloss.

Repainting

In some cases, when polishing does not remove staining defects, it will be important to repaint the entire surface. Before repainting, it is necessary to smooth out the most defective areas with fine-grained sandpaper.

Painting a car without the appearance of shagreen is the rule, not the exception. At the same time, its occurrence is a minor tragedy. Shagreen is only a cosmetic flaw and does not in any way threaten the integrity of the body and coating. The car owner decides whether to remove or leave the shagreen after painting the car; it all depends only on the appearance and degree of the defect.

Painting a car is a rather complicated technical process that requires compliance with all requirements and conditions.

Painting a car without shagreen is quite accessible to any car enthusiast; the main thing is to strictly follow the specified requirements, as well as the recommendations of manufacturers of painting materials.

Shagreen surface effect

The “shagreen” texture is a modern trend in the design of apartments and houses, loved by designers. A very convenient type of painting that hides minor surface defects well and does not require preliminary puttying or plastering - unless, of course, there are potholes and cracks deeper than 2 mm on the walls.

A large selection of colors and shades makes this textured paint very popular. In addition, it is applied to the surface only once, which greatly facilitates and simplifies painting work.

Textured compositions are produced based on water-based paints. They are prepared in a special paddle mixer, loading it with synthetic-based water-based paint and fillers - potassium glass and marshallite. The prepared composition is kept for about half an hour, after which it becomes completely homogeneous.

The surface is first thoroughly cleaned and primed with a synthetic paint composition. After the primer has dried, paint is applied in one or two layers 1-2 mm thick. You can use a spray gun or, for small areas, a paint roller.

There is no need to try to cover large surface imperfections with just textured paint. If there are large depressions and irregularities on the base, they will still have to be repaired first. Now they produce textured plasters that can be used for this purpose. After drying, the plaster is coated with acrylic paint, and the shagreen effect is preserved.

Powder formulations

Powder compositions are used to paint metal surfaces. They also give a good shagreen effect, masking scratches and unevenness. Here you need to focus on the object that needs to be decorated.

Polyester paint shagreen is more suitable for products intended for outdoor use. Such compositions withstand the vagaries of the weather well and protect the object from the negative effects of atmospheric phenomena.

If the product or structure is exposed to chemicals, then it is better to use epoxy-based paint. Mixed epoxy-polyester paints are used for indoor structures.

Based on textured compositions, you can achieve a very interesting “Antique” effect. The fact is that the protrusions on the painted surface are slightly different from the color of the base. The result is original shades, given the variety of colors of powder paints.

Paints with a shagreen effect are wear-resistant, abrasion-resistant, do not fade, significantly save money on repairs and have a unique, original appearance. The use of such compositions in the design of premises, metal products and structures gives them strength, resistance to the external environment and a special charm.

Effective ways to remove shagreen

When painting a car or part of its body, sometimes a cosmetic defect occurs in the form of a small uneven surface (shagreen), which looks like an orange peel. The appearance of such a defect is possible at any stage of applying paint and varnish mixtures, and even during varnishing, if they are carried out in violation of the technological sequence or without following the recommendations contained in the instructions for the paint.

Irregularities can be either small in size (fractions of a millimeter) or very significant in size (0.5-0.7 centimeters). In addition, the visual visibility of defects is affected by the color of the coating. White shagreen is noticeable on a car much more than similar flaws on a dark-colored body. Therefore, owners of light-colored vehicles are often concerned about how to remove shagreen.

Types of powder dyes

The composition of shagreen paint may vary depending on the direction of application. First of all, shagreen is distinguished by the type of main component. Paint can be:

polyester;
epoxy;
polyester-epoxy.

Polyester shagreen paint is intended for coating objects and surfaces that are directly exposed to natural factors: rain, snow, wind, frost and direct sunlight. If the object being painted is threatened by acids or alkalis, then it is better to choose epoxy paint. For surfaces that are constantly indoors, polyester-epoxy shagreen paint is suitable.

On the market of paints and varnishes, polyester-epoxy shagreen paint with a color gradation effect is often found. This means that the upper part of the resulting “grains” - roughness - will differ in color from the main shade. So, for example, you can get silver tops on a white background, or golden ones on a black background. The name of the paint in this case speaks for itself. Antique shagreen, illustrating the examples above:

Shagreen is also distinguished by the size of the resulting roughness. Depending on this, the paint can be coarse or fine-grained. In this case, the choice of shagreen is determined only by the quality and type of the desired coating. However, it is worth remembering that to obtain a coarse-grained pattern, the consumption of powder paint will be much greater than for a fine-grained pattern.

Reasons for the formation of shagreen

Beginner painters very often encounter the problem of shagreen paint after painting a car. Of course, adherence to technology and a responsible approach to work will help minimize the possibility of defects. But in order to completely get rid of shagreen, you will also need ideal atmospheric conditions with a certain level of humidity and temperature. Among the main factors that contribute to the emergence of such shortcomings are the following:

Incorrect adjustment of the spray gun. If the gun nozzle is not at the optimal distance, then this location often leads to paint splashing. Therefore, it is important to select the correct diameter of the spray hole of the device and pre-adjust the air stream.
Inconsistency of the microclimate in the box. To ensure uniform drying of paint and varnish products, it is necessary to adhere to the temperature regime. So, if the hangar is too hot, this can lead to increased evaporation of the solvent and premature hardening of the paint. Otherwise, it will dry very slowly, forming clumps.
Uneven operation of the compressor. The consequence of the air “spitting” of this electrical apparatus is the uneven distribution of enamel and the formation of shagreen.
Chemical incompatibility of the solvent with varnish or primer. The issue of choosing a solvent that matches the primer and varnish is extremely relevant. And if this factor is neglected, all the work can go down the drain.
Insufficient paint viscosity. This problem can occur if the technology for preparing its composition has been violated, or the wrong container has been selected for measuring the dosage of components. Painting a car is a very serious undertaking, and here you cannot add hardener and thinner “by eye” without adhering to the proportions.
Storing the coloring composition in a cool place.

The final result depends on the quality of the work at each stage. Priming, enameling, varnishing of the car body - all this must be performed at the highest level. Even a minor mistake in one of the steps can lead to a defect appearing after painting and drying is completed.

Instructions for spray painting a car

The dyeing process is divided into a certain number of stages. At the first stage, preparatory work is carried out, which includes cleaning the body, degreasing work, and the use of anti-silicone.

At the next stage, you need to decide on the shade. Having previously checked the body marking instructions, a specialized store will help you choose the required option.

To prevent an error, colorize the body. Specialized equipment and software will evaluate the level of color fading and other factors.

It is worth noting that you will have to spend a lot of money on the procedure. In addition, paint options such as “metallic” or “chameleon” cost much more, because these shades are the most popular.

Methods for removing shagreen

Professional painters know very well from their own experience how to remove shagreen. There are two main ways to remove it:

The first method is more preferable, and if the situation with poor-quality paint application can still be corrected, then it is used. The second option is an extreme measure that the master has to take in case of complete failure.

Polishing

Minor irregularities on the surface of the car appear even if painted in conditions close to ideal. Simple roughness can be removed by cleaning using any abrasive materials. At the initial stage of polishing, sandpaper with a grain size from P1200 to P1500 is used: a small rubber or wooden block is wrapped in sandpaper and a smooth, uniform surface treatment with defects occurs. During the process, it is periodically necessary to wash off the resulting dust and microparticles of paint from the working surface. To do this, it is recommended to use clean distilled water, the excess of which is removed with a rubber sponge.

After rough processing, finishing matting is carried out with abrasive paper numbers P2000 or P2500. At the final stage, special pastes are applied to the body, after which the surface acquires gloss and shine.

Also, to remove shagreen, they produce special Trizact grinding discs for polishing machines. They have a soft backing onto which abrasive particles with a grit size of P2000 or P3000 are sprayed. Such devices greatly facilitate the work and do not leave behind deep scratches.

Repainting

If the paint applied to the surface unsuccessfully and the white shagreen remains even after mechanical treatment, you will have to start work from the very beginning. In this case, it will be necessary to completely remove the old coating so that its flaws do not appear in the future. In addition, the previous protective material may be incompatible with the new one. Therefore, repainting is a very labor-intensive operation.

Subtleties of the process

Elimination of smudges should be carried out on a dry coating. If the paint is not completely dry, this can lead to separation of the bead along with the paint layer. Cavities and enamel detachment may occur. Place masking tape around the defect. Use a blade to cut off the influx, starting from the top to the base. Then they move on to sanding. To do this, wrap a rubber block in sandpaper and moisten it with a soap solution. Then they change the skin to a less grainy one. Too large smudges can be cut off while they are still wet. After removing the buildup, apply a thin layer of putty and after 20 minutes sand it using the technology described above. It is much easier to remove small smudges. If it is a small part, it can be turned over in the opposite direction to the direction of the leak. If the smudge is barely noticeable, you can touch it up a little.

Alternative methods of applying paint to a car body

Powder painting of cars will help to avoid the possibility of unevenness and cosmetic defects as much as possible. This technology makes it possible to obtain high-quality polymer coatings with minimal material consumption and good performance properties. And special additives that regulate spreading and have good corrosion resistance provide reliable protection to the body metal.

The powder paint method has a number of undeniable advantages, which has led to the popularity of its use in the modern automotive industry.

Preparatory procedures, how to paint correctly

If you decide to carry out all the repair work on your own, then you should do everything as soon as possible. Once you discover damage, do not delay the process, as the problem may get worse.

Once the scratch reaches the metal, the oxidation process begins, leading to rust and corrosion. Because of these defects, more serious work will be required.

Before painting, the car is cleaned using conventional detergents. You need to wait until the surface is dry and then degrease it.

For this, special wipes and solvent are used. After saturating one napkin with it, wipe the surface dry with the second. To ensure greater comfort, you need to remove the part that will be worked on.

All other areas of the body that cannot be painted are covered with protective film and masking tape.

To prevent painting defects from appearing, a special chamber is needed; the room must be completely clean of dust and other contaminants. Lights, like devices, should be directed toward the work surface to avoid glare.

Work should not be carried out outdoors, as exposure to sunlight will negatively affect the result. At high temperatures outside, only the first layer is subject to drying out; it will take longer to wait for complete drying.

Therefore, before applying a new layer, wait until the previous one dries.

Before spraying the can, you should shake it well. Try not to go overboard and cover up the rest of the components.

If you are not sure of the result, then you can try your hand at an old part that you have.

Don't forget to follow the existing instructions and stock up on the following tools:

paint,
sandpaper of different levels,
putty and primer,
antisilicon,
polyethylene,
masking tape,
elements for protection.

When doing all the work yourself, be sure to consider hand protection; use a rubber or silicone spatula so as not to cause unnecessary damage to the surface.

The work of the aerosol begins only after the primer has been applied, dried and polished.

Shagreen after painting a car - how to deal with the problem?

Painting a car is a complex and specific task that needs to be done professionally. If the painting process is done incorrectly, after its completion you will have to remove a lot of unpleasant little things. This will delay the work and make the appearance of the machine of lesser quality. Lumps of paint, unpleasant streaks and drops, dots and an uneven layer - all this happens when you approach the car inappropriately or in the wrong conditions. Shagreen when painting a car sometimes occurs even among specialists with extensive experience.

Shagreen is an “orange peel” that can be very noticeable or quite fine. If painting is done by a specialist in a chamber, then this effect will not be noticeable. If you use high-quality materials and good equipment, you can completely avoid such a nuisance. Such effects can be removed either by redoing the work in a certain area or without painting. Shagreen leather should not be allowed to appear on a beautiful car. Let's take a closer look at this point.

When shagreen is a virtue

Among car enthusiasts, shagreen is considered a defect, but in many ways it is an advantage. For example, for painting safes or commercial equipment, dyes with shagreen – powder paints – are specially used.

Due to its original relief and appearance, this coating is used to hide minor defects in welds. The coating can be either matte or glossy, there is a large selection of colors. The color with shagreen looks impressive.

Using powder paint, an “antique” effect is achieved - the tops of the tubercles have a color different from the base one. The result is a very beautiful visual effect.

Shagreen is also perfect for painting walls. You can create interesting design effects. The color in combination with the relief surface of the walls will look very attractive.

Now you know what shagreen means during painting work - it can be either a defect or a decorative coating. It all depends on what and how to paint.

Why might shagreen appear on your car?

Lumps of paint material on a car can be seen during unprofessional painting. Incorrect distance of the gun from the metal or incorrect hand movements will result in poor paint application to the surface. But this is not the only reason for such trouble. The performer’s limited experience should always be taken into account, not allowing a beginner to carry out responsible work on expensive areas. Shagreen can appear on car body parts for the following reasons:

low quality paint - in this case it will be very difficult to remove this defect by any means;

poor compressor performance during painting work, low or too high pressure;

a clogged spray gun that has not been washed properly for a long time, poor atomization;

poor-quality metal preparation before painting, textured putty surface;

poor quality of the primer used to expose the part before applying the paint and varnish material.

The choice of method to remove the effect depends on the cause of the appearance of shagreen. There are two options for car processing to eliminate such consequences. This is a treatment that involves removing a layer of paint, and also without repainting the car. If shagreen appears on the entire surface of the car after painting, you will have to take a more serious approach to eliminating the problem. Most likely, the preparation was performed poorly.

Let's sum it up

An unpleasant shagreen defect on the body of your car can occur when painting metal parts. Most often, this effect is present when an inexperienced specialist is working, but it can also arise for other reasons. It is important to notice the “orange peel” on body parts in time and carry out restoration to eliminate the unpleasant visual defect. It can be eliminated by polishing or repainting the area.

Of course, it is better to avoid poor-quality painting, since it will be very difficult to remove this nuisance without visible visual consequences on the car. Sometimes specialists have to completely repaint the entire part on which the shagreen appeared. Even if such an unpleasant situation arises when painting a car, everything can be eliminated. Read the instructions for combating this phenomenon and carry out all procedures efficiently and without unnecessary nerves. This will help make the car beautiful again.

Eliminating the defect - the main methods of combating without painting

To save your car from shagreen and not have to repaint the car again, spending a lot of money on materials, you can try to eliminate the defect by polishing. But in this case, the polishing technology will be slightly different than with standard refreshment of the paintwork. It is important to observe all the features and stages of the polishing process:

Wait a day after painting so that the paintwork adheres properly.
Use 1500 grit sandpaper and matte the surface.
You can use wash technology to matt the top layer.
Next, apply polishing abrasive paste to the damaged area.
Use a polishing machine with a soft felt pad to polish.
Repeat the procedure after finishing the paste on the area several more times.

All that remains is to wash off the unused remnants of the paste and evaluate the result. But if the painting was done too poorly, polishing work will not always help correct the situation. Sometimes you will have to use a drastic method to correct errors and repaint part of the car.

How to spray paint a car - step by step guide

No matter how diligently you take care of your car, it is impossible to avoid minor scratches and damage.
Most often, the top layer of paint is damaged when parking, when the doors were unsuccessfully opened or there were stones on the road.

In any case, the damage is not significant, it is not always possible to notice it immediately, but over time it can turn into a serious threat and become a problem.

In this case, you just need to contact a car service. There you will already have to shell out a more serious amount of money.

Therefore, while the problem is insignificant, they prefer to eliminate it at the root, not go anywhere, but simply paint it on their own using spray paint.

The method is very economical and does not require special knowledge.

Removing the “orange peel” with high-quality painting

Even many experts with extensive experience sometimes wonder how to remove shagreen after painting a car. This is a rather difficult task, which is performed individually in each individual case. To get rid of troubles on the surface of metal parts, from various bumps and pits, you will have to perform the following procedures:

Wash the paint down to the primer, leaving no old enamel on the damaged area.
Assess the quality of the soil and, if necessary, wash it down to metal.
Perform metal processing to eliminate unpleasant effects in the future.
Open up the area with a new layer of primer and wash the top part again for a smooth surface.
After the primer has dried, paint the area using high-quality enamel.

Also, after completing all the processes, it is necessary to thoroughly polish the paintwork, making sure that there are no unpleasant effects. The car will look great if all processes are carried out efficiently. But in the case of local painting, other problems are possible. If the transition to the old coating is not done professionally, you will have to deal with a visible spot of local paint. So this task is also performed only by specialists.
