How and what to process the bottom of the car against corrosion?

Most car enthusiasts buying a car try to save money and do not consider it necessary to carry out anti-corrosion treatment of their car. They rely entirely on factory processing. This is permissible if the car is bought for a short time. If you drive a car for a long time, then the bottom should be processed immediately after purchase. Let's find out how to properly process the bottom of the car and what means for this exist.

Why spend

When the car moves its bottom is constantly exposed to small stones, gravel, small particles of asphalt, as well as other objects that fly out from under the wheels. Snow and ice, road salt, various dirt - all this aggressively affects the surface of the metal coating. As a result of this influence, the paint exfoliates, chipped and microcracks appear. Already the exposed metal gets moisture and causes corrosion. Metal eventually rusts not only in damaged areas, but under a layer of the whole paint, because there is condensation at too rapid temperature changes. Anticorrosive treatment of the bottom of the car avoids all these problems.

Processing from manufacturers

At automobile factories, especially in our country, the body and the bottom of the machine are not treated for corrosion at all. Therefore, those who purchase such cars should prioritize such treatment - this will increase the life of the bottom and body.

In new cars of foreign brands, the bottom is covered with a protective layer by anodizing, and a zinc coating is applied, which can protect against premature corrosion. Owners of new foreign cars may not carry out processing for 5 years. But for used cars of foreign manufacturers, a mandatory inspection is necessary, because nobody knows if the bottom was restored during pre-sale preparation. Even if the body is restored, it is still necessary to apply materials for processing the bottom of the car.

Metal over time can accumulate in itself fatigue. These processes contribute to lowering the strength characteristics of the body. Oxidizing and corrosive processes greatly accelerate the accumulation of this fatigue.

Kinds

Means of anticorrosive protection can be made on the basis of several components. So, sometimes there are mixtures in which there are aggressive substances. They can significantly damage the bottom coating. Therefore, it is worthwhile to know how to treat the bottom of the car against corrosion, so that it is both reliable and safe.

In its composition, the materials for corrosion protection are divided into wax and bitumen. According to their purpose, the funds are also divided into two groups. The first group is mixtures for hidden internal surfaces. The second group is designed to protect exposed surfaces. This is what can be used to treat the bottom of the car against corrosion.

Types of mixtures for internal surfaces

So, for the protection of hidden surfaces apply non-drying compounds. This mixture has a liquid state. The drug completely fills all microcracks and other defects and leaves no room for oxidative and corrosive processes. Wax or paraffin formulations can also be used. The preparation forms a special film on the surface. It reliably retains the internal parts from the effects of moisture and oxidative processes. If you are looking for what to process the bottom inside the car, the wax-based compounds are very effective and popular. This protection is also good because it works and does not lose its efficiency over wide temperature ranges.

Types of means for open surfaces

In order to protect the external surfaces from corrosion, a bituminous mastic, PVC mastic, and liquid plastic are recommended .

The bitumen mastic includes bitumen itself, as well as synthetic oils. Mastic can act as an anti-gravel treatment of the bottom of the car, and also protect the surface of the metal from access to oxygen. These compounds are recommended to apply a thin layer on the bottom of the car. The thickness of the layer should be from 0.25 to 0.4 mm.

PVC mastics are created on the basis of rubber. Their strength is quite high, as well as overall efficiency. These coatings have established themselves as one of the most durable. Often these mixtures are used in factories, as special conditions are required for application and creation.

Liquid plastic does not have high resistance to mechanical influences, therefore it is used rather as a second cosmetic layer after the main anticorrosive material.

Anticorrosive products: market review

For those who are looking for what to process the bottom of the car against corrosion, the modern market offers a lot of different options and means. Let's look at what they are.

WAXOYL HARDWAX: anticorrosive for the bottom

The mixture is supplied in cartridges. The manufacturer claims that this compound is ideal for exterior body parts and is designed to protect against corrosion of the car's bottom and wheel arches. This mixture is produced in Switzerland.

Pack the mixture in cans of 5 liters, in metal drums in volume 58 and 200 liters. The mixture is black. With regard to consumption, then for 1 square. M need from 0.15 to 0.18 liters of the composition. As stated by the manufacturer, the processing of one car may require about 2 liters of this drug. The thickness of the applied layer is from 60 to 80 μm.

The mixture is a mastic with anticorrosive properties from solutions of various paraffins, bituminous particles, as well as corrosion inhibitors. These substances were dissolved in white spirit. Before processing the bottom of the car against corrosion, it is necessary to clean the surface of dirt, as well as rust, which lies in layers. After cleaning, the surface can not be dried.

As an advantage, it is emphasized that the preparation perfectly fights with different foci of rust, and also withstands various and even extreme climatic conditions. For the climate of our country this is what is needed. When it's hot, the product does not flow when it's cold - the coating does not lose its plasticity. The composition can be applied either by air or by airless method. If you fully comply with the technology, you can get excellent results. If you do not know what is best to handle the bottom of the car, try this option.

RAST STOP "B"

This is another drug that is positioned as a treatment for the bottom. Supplied in cans of 520 ml, in canisters of 1 liter and in barrels. Expenditure of funds per 1 square. M is about 0.6 liters. To handle this composition of a middle class car, you will have to stock up 2 liters of this drug.

This tool can be used both professionally and for self-processing. The composition of the composition is based on high purification oils.

This is an uncurable compound. It is constantly in semi-liquid state. A special group of additives allows this mixture to easily penetrate into cracks and various defects. The mixture effectively protects not only against corrosion, but also from the electrolyte.

The manufacturer recommends applying a layer of mastic by airless spraying. In this case, it is possible to achieve a higher surface quality. The composition can also be applied with a brush, which is very important for those who are looking for what you can handle the bottom of the car with your own hands.

NOVA GOLD

This is another tool for anti-corrosion protection of cars. This drug can be used for any type of car. The composition can be applied both in professional conditions and with your own hands, which is relevant for experienced motorists. They are accustomed to servicing their cars on their own and do not think about where to process the bottom of the car.

The composition is a suspension of metallic fillers with bituminous alkanes. Supplied in aerosol cans, canisters in 1 liter, in barrels.

Excellent anticorrosion treatment of the bottom of the car will be with the means of "Nova Gold". For the application of this material, there is no need to somehow prepare the metal. It can be applied either by air or by airless method. If you do the work yourself, the manufacturer allows you to apply the tool with a brush.

The composition of this preparation allows it to combat corrosion very effectively. The protection works for a long time. If you are looking for better treatment of the bottom of the car, then this compound is ideal for you.

Handling the bottom with your own hands

You already know which processing aids you can use. Applying the compound on the bottom is very simple. The work is done in several stages. The first thing you need to call a pit or flyover. Then you need to light up the working surface and remove the wheels. Further, before processing the bottom of the car, the surface is cleaned of dust and dirt. After all, the remedy will be kept only on the cleanest possible surface. Clear the bottom is possible with the help of a strong head of water. After thorough washing, the surface must be dried. This will help purge the compressed air. Then assess the state of lacquers and paints on the bottom, remove all defects, delamination and swelling. For this you need to use a special tool. Then the surface is degreased. On the dry bottom, zinc-containing primers are applied, and then after drying, the agent that you have chosen. If you do not yet know what to process the bottom of the car, modern manufacturers offer a variety of options available. Then the mastic is applied. It is necessary to do breaks to dry the layers. After work, the layer will be approximately 2 mm. It is better to use the means in jerricans, cylinders can be expensive. So, we figured out how and how to treat the bottom of the car against corrosion.
