LKP in the car is what? Car thickness: table

The paint and varnish coating (LKP) is responsible for the external component of the car. It is the first impression that is remembered most, but it will not be positive if the machine looks ill-colored, with many defects on the surface. How to prevent this and how to fix the problems in an incorrectly colored car?

What is LCP?

When buying a vehicle one of the experts' recommendations is to pay attention to the LKP in the car. What's this?

LCP is deciphered as a paint and varnish covering. It should be paid special attention due to the fact that the defects can not be seen immediately, but the car body of the car is damaged very quickly, and even in a fairly new car they can appear in a matter of days.

In addition, when buying a vehicle in the secondary market, very often machines are after major repairs. The fact that a car has been in an accident is always hidden by the seller, but it is not difficult to identify it. For this, an examination of the vehicle's LKP is carried out, the data is obtained with the help of a special device and checked against the GOST. On them it is easy to find out the fate of the vehicle, since at sale hide defects very carefully.

Paint Coating Thickness

The requirements of the standards primarily apply to the thickness of the coating layer. It is measured in microns. Below is a table of LKP cars of different brands. It is made up more for producers. Nevertheless, it is useful to ordinary car owners, since it is not difficult to identify deviations during the examination.

Car thickness. Table

car model	Model	Interval LCP
"Nissan"	X-Trail, Patrol, Juke, Qashqai, Murano, Tilda, Pathfinder	From 80 to 120
"Peugeot"	208, 308, 508, 3008	From 100 to 120
"Skoda"	Octavia, Yeti, Superb, Fabia, Roomster	From 100 to 145
"Suzuki"	Grand Vitara, SX4, Swift, Splash	From 85 to 115
"Toyota"	LC200, Camry, Highlander, Auris, Verso	From 95 to 130
	Avensis, Corolla, Prado, Prius, RAV4	From 80 to 110
"Volkswagen"	Polo, Golf	From 80 to 110
	Tiguan, Passat, Caddy, Multivan, Amarok	105 to 140
	Touareg, Jetta	From 140 to 180

When carrying out the measurements before buying a car, a layer of paint more than 300 microns may become a reason for excitement. This means that it hides chipped and small defects. If the car was in serious repair, then the thickness can be more than 500 microns, this indicates the inept concealment of the traces of the accident. Obligatory to the comparison GOST requirements, the thickness of cars LKP, the table of values of which is presented above, can help the owners of machines.

Other requirements of GOST for LCP

The choice of coating for a new car must meet the following requirements:

• Color paint body - for different types of cars set its standard, so for large equipment should be warm or contrasting colors, say, blue with yellow;
• The invoice must also correspond to the brand of the car, the car for personal use can be both glossy and matte, but the great technique should preferably be smooth;
• The outer shell and large parts inside the car are covered with special care;
• The paint class should correspond to the class of the car and depends on the location of the parts.

It is important to know not only the concept of LCP in a car, it is what and how to choose it, but also how to apply it in case of repair.

Before applying the coating, the surface must be properly treated. GOST for each type of material and the staining method gives its list of actions, each of which has such items:

• Removes fat from the surface;
• Primer application for good adhesion;
• A protective anticorrosive layer is created;
• Treatment with passivating solutions;
• Application of oxidants to create a protective chemical and anodic film;
• Grinding is performed.

Every car owner needs to know about LCP, what it is in the car, how it should look and be applied.

The main types of defects and the causes of their occurrence

Defects often occur due to inexperience of the master, improper treatment of the metal before coating and due to many external factors.

The main reasons are incorrect external conditions of painting, violation of the principles of working with materials and inept handling.

If repair is planned, the car's LKP should be given special attention, since the following defects may occur.

Thin cracks

This defect has the form of thin long cracks not connected with each other, they differ little, but create a common somewhat repulsive appearance. On the surface it looks like a cloudy spot or a site devoid of luster. With increasing loads, cracks become larger, the defect area increases.

Causes:

• Poor-quality preparation for painting;
• Violation of the technology of work with the material;
• Poor-quality paint;
• Violation in the treatment with a primer;
• Incorrect mixing of paints;
• Too much material;
• The paint badly dried.

To eliminate such troubles, one should not only learn about the damage done to the car in the car (this is what we found at the beginning of the article), their reasons, but also to consult what kind of coverage is more suitable for the body. Most often all the paint that has such defects should be removed and painted again.

The presence of craters and funnels on the surface

This defect occurs immediately after staining. It is caused mainly by silicone particles that enter the polishing mixture.

Causes of occurrence:

• Poor cleaning before painting;
• Use of soap;
• Particles of dust, polishing material, the presence of villi that remained on the surface;
• Use of poor-quality materials.

When a local repair of the car's lacquer is carried out, it is necessary to remove silicone residues from the surface, clean it well and apply a new coat of paint.

Insufficient adhesion

The quality of the painting is highly dependent on the adhesion to the surface. Sometimes the material is simply chunks separated from the metal or old coating. The defect manifests itself almost immediately after the application of the paint and is particularly noticeable on the places of old strokes.

To avoid this problem, you need to know about the quality of the paint in the car. What does it mean? What could have led to its appearance? It can be:

• Poorly prepared surface;
• Remnants of rust, oils, wax;
• Uneven priming;
• Poorly mixed materials;
• Violation of the technological process of painting;
• Use of solvent of poor quality;
• Exposure to too high temperatures during drying.

When dealing with these defects, remove the paint from a sufficiently large surface, much larger than the damaged area. The surface is sanded using a sandblaster or a grinder.

Blistering

High-quality painting requires a perfectly flat surface. Bubbles appear on old and new layers of paint, the main reason - a sharp drop in temperatures during drying.

The main causes of bubbles:

• Getting moisture or air under the paint;
• Poor surface preparation, residues of contaminants on it;
• Use of a poor-quality solvent;
• Insufficiently well-dried lower layers of paint;
• A high viscosity of the paint, which led to the surface boiling;
• Too much primer or paint.

Defect can be removed, only completely repainting the car.

Layering of paintwork

This defect arises with time even after the factory painting.

Main reasons:

• Residues of contamination;
• Too high ambient temperature when working with materials;
• Very small amount of primer;
• Poorly smoothed the layers between the paint;
• Poor interaction of primer, paint and coating.

To get rid of this defect, you need to remove all the paint down to the bottom layer, and often to the metal.

Presence of percusses and influxes

Usually occurs on inclined surfaces. The reasons are as follows:

• Too high intensity of spraying;
• High atmospheric pressure;
• Too dense layer of paint;
• Slow evaporation of the solvent;
• Poorly dried layers.

The plot needs to be well polished and cleaned, and then repainted again.

Turbid surface

The defect looks like a muddy-white badly stained spot. It is unpleasant in that it eventually leads to other defects, such as cracks and the formation of bubbles.

Main reasons:

• ; Painting in conditions of high humidity ;
• Use of a poor-quality solvent;
• Solvent is added more than necessary;
• Incorrect air circulation in the room where the painting is done.

You can get rid of by polishing the surface.

Plaque similar to dust

It looks in the form of poorly colored drops of different diameters.

Causes of occurrence:

• A solvent having the property of rapid drying;
• Inaccurate application of paint and its exposure to different surfaces without further cleaning;
• The paint dried up too quickly.

The defect can be easily eliminated by grinding the damaged section.

Matte coating

High-quality painting involves obtaining a shiny surface.

The causes of haze may be:

• Uneven coverage;
• Insufficient thickness of the material;
• The presence of scratches before painting.

For elimination, the surface is smoothed again and another layer of paint is applied.

How to protect the car cover?

Protection of the car's LCP involves the use of various drugs.

1. Application of polishes and waxes. These materials can brighten the car, have a moisture-repellent basis, and also protect against minor damage. In addition, they repel road dust and protect against organic attack. Service life - from one year to three, it depends on the price and quality of the application.

2. Use of "liquid glass". This material is applied in a thick layer and creates a spectacular appearance. Such a glass film can protect the car for three years.

3. You need to know not only about LKP, what it is in a car, but how to protect it. Another method of protection is the "liquid cover", it is available, easy to apply and well protects from scratches, but its service is short enough.

4. Protective film. It is applied to the machine parts and fits snugly against the previously cleaned surface. It has an aesthetic appearance, allows you to make the coating matte or more shiny.

5. Cloth cover. It is selected for a particular car. The disadvantage is the fact that getting under the cover of small debris is difficult to track, and it can significantly destroy the paintwork.

6. Plastic and acrylic deflectors, which simply blow off debris from the surface of the car.

Thus, it is important not only to properly prepare the surface for paint, choose the right material, but also protect it from possible damage.
