How to paint a car with Gravitex

Recently, the excitement around body painting with Gravitex has been gaining momentum. It suddenly became terribly fashionable and, it seems, absolutely necessary for everyone. But in reality - is this so? More recently, everyone was quite aware of the existence of such a procedure as priming a car body - there was no special excitement or promises of something unusual around it. And then Gravitex appeared, which seemed to offer approximately the same functions, but at the same time became terribly popular and necessary. Practice says that Gravitex actually gives a better result than conventional polishing. But it also costs more - you may need special equipment, for which the owner of the service will definitely take a percentage. So, what will you get if you decide to undergo such a procedure?

Rules for painting cars with Gravitex.

What is the secret of gravitex

So, what kind of secret does this fashionable composition keep, which is gaining popularity in the market by leaps and bounds? The name of this composition is not a trademark - different manufacturers produce compositions under this name. The composition may vary slightly from one to another. But, in general, the composition will be similar - it is a set of ingredients such as:

Synthetic resins in different proportions and with various impurities. From brand to brand, from budget to budget, their composition may vary.
Organic solvents may also vary the volume of this part of the composition and the specific ingredients.
Rubber.

This is exactly the composition of that “magic” protective layer that keeps the surface safe and sound, protecting it from various damages. What is gravitex for cars? First of all, it is film. A very important property of the film that is formed after painting with an anti-gravel composition is its elasticity. That is, if the metal moves imperceptibly, the film will also change shape. With normal polishing, it will flake and chip.

Benefits of anti-gravel products

The initial anti-gravel treatment of the car body (its lower parts) is carried out at the factory during the production of the car. However, over time, this composition loses its properties, which can lead to damage to the coating of the part. Therefore, to restore the protective layer, anti-gravel is used for the body, providing protection for its paintwork and/or the materials from which its components are made (metal, plastic).

The advantages of anti-gravel treatment of a car body can be identified as follows:

The coating formed by it (usually a polymer film) provides reliable mechanical protection that protects the treated sills, wheel arches and the bottom (optional) from the abrasive effects of sand, small pebbles, gravel and other solid particles when the car is moving. This protects their paintwork.
Protecting the coating from penetrating moisture, which, in turn, can cause corrosion. Thus, anti-gravel is an anti-corrosion treatment for the lower part of the body. This allows you to protect the metal no worse than special anti-corrosive compounds.
Protection of paintwork from exposure to ultraviolet radiation (sun rays), which causes fading, that is, loss of the original color. However, not all anti-gravel agents have this effect, but only for the most part those that can be applied directly to the paintwork (many cannot be applied to it).
Creation of vibration and noise insulation. Anti-gravel coating of the wheel arches provides an increase in sound insulation by approximately 40% (average value, it may differ for different products).
Protection of surfaces from exposure to oil and/or fuel, as well as other aggressive process liquids.

Some anti-gravel agents have additional benefits. For example:

products with a shagreen effect adhere better to the surface being treated;
with the help of some of them it is also possible to create a protective layer on plastic and/or rubber parts, thus protecting them from wear and exposure to ultraviolet radiation;
some anti-gravity agents are excellent at displacing moisture from small internal cavities on the body (for example, from headlight cavities);
universal products that have the function of anti-gravel and “liquid rubber” can significantly improve the aesthetic component, updating the appearance of the body paintwork.

Nuances and features of the composition

This last indicated property allows the successful use of gravitex in the following cases:

When you need to treat thresholds that are constantly exposed to mechanical stress.
Similarly in the case of the lower openings of car doors.
If the car is supplied without fender liners, you can also apply gravitex to the wheel arches.
Naturally, they need to process the underbody of the car, which is constantly exposed to mechanical impacts from various debris from the road, stones, etc.
The lower edges of doors are a very vulnerable area that wears out quickly.
Any plastic covers to provide additional protection.

There are even fans who cover absolutely the entire car with this composition. Literally from the wheels to the roof. This is really very convenient if the car travels a lot over rough terrain or bad roads.

Disadvantages of anti-gravel

However, there are also minor drawbacks to the process of using anti-gravel agents. Among them:

Anti-gravel compositions are harmful to the human body. Accordingly, during the application process it is necessary to use personal protective equipment - gloves, goggles, preferably a respirator. In addition, you need to paint with anti-gravel in a well-ventilated area or outside. Before operation, carefully read the safety precautions in the operating instructions!
High cost of anti-gravel treatment. Despite the fact that the price of one aerosol can of anti-gravel is relatively low, each of them is designed for a large area to be treated. It is also worth adding here the fact that processing is usually carried out in 2…4 layers. However, preventive treatment with anti-gravel allows you to keep the paintwork of thresholds and other body parts in good condition for a long time. · Most anti-gravel in packages after printing are not stored for a long time, but instead lose their performance properties. Therefore, there is no need to buy these funds for future use.

Thus, the advantages outweigh the disadvantages, so treating the thresholds with anti-gravel is an excellent preventative measure for a car with any mileage.

We use it correctly, in accordance with technology

Well, and most importantly, how should the composition be applied correctly? First of all, you must find out all the details. We believe that you have already figured out the type of container and coloring. Now let's move on to the technical details.

For example, do you need to prime before painting?
How long will each individual layer take to dry?
What type is acceptable for treatment with this anti-gravel?
If you choose a pistol, what is the nozzle diameter?
What air pressure do you need?
What layer thickness should be maintained? Did the master dilute the composition?

Once all these nuances have been clarified, you can proceed directly to painting in accordance with the instructions. Since the entire process is usually described in some detail in the instructions, we will not repeat it.

Do-it-yourself anti-gravel treatment

Gravitex can be applied correctly in several ways. The technology will depend on the method of combining the protective layers of metal. But there are a number of preparatory operations that are valid for all types of anti-gravel treatment.

Thoroughly wash and dry the surface to be treated;
remove all areas of corrosion;
degrease the surface;

As we saw with the example of Novol GRAVIT 600 MS, the manufacturer allows gravitex to be applied to “bare” metal. If you applied gravitex to unprotected metal, after drying the surface must be varnished.

Anti-gravel, if you look at it under a microscope, has a porous structure, which suggests the ingress of some amount of moisture. In addition, constant temperature changes and gravel flying from under the wheels have a negative impact on the coating.

Over time, the protective layer will crack and begin to peel off (after 3-4 years this can happen even if you apply anti-gravel to an old glossy paintwork). Therefore, we recommend priming the surface before treating with gravitex. After drying, the primer should be sanded with P240 abrasive, and only then the compound should be applied. Even if you used a primer, coating with varnish will only increase the degree of protection.

Bottom treatment

It is not always possible to properly prepare the surface, and this is a failure.

Gravitex needs to be blown out with some kind of paint.

Surely no one has used BODY 950 to put on the bottom. Even in the store they advised me to use anti-gravel. Someone told me whether it absorbs water or not, it seems like it has a rubber base.

Anti-gravel does not absorb, but it can become porous and allow dirt and moisture to pass through. To guarantee, it is painted on top, with any paint, or with a brush, if on the bottom. It won’t help with rust; it will still swell in the winter. You need to clean off the rust and prime it, only then apply mastic. I would recommend epoxy auto primer. It does not allow water to pass through and, as a rule, it also contains anti-corrosion additives. Anti-gravel provides mechanical protection from stones, sand, etc.

The best examples of bright and anti-theft tuning

The most impressive look are business class cars, in which one part of the body has a familiar look, is beautifully painted and shines with metal, and the other part is covered with rust. Such a car invariably attracts attention and causes amazement among passers-by.

Powerful SUVs with all the attributes of a car for extreme travel in a rusty body will look as if they have recently returned from a dangerous expedition.

The best aerosol products:

Gravitex BODY 950 is universal, available in 3 colors (white, black and grey). Old Greek company, easily available in stores.

Disadvantages: it does not stick well, so it requires cleaning and degreasing. Increased consumption.

As a replacement, for larger volumes of work, use the less expensive and non-paintable BODY 900.

KERRY. Russian brand of Moscow JSC Elf Filling. The ideal combination of price and quality. 3 colors - white, gray and black. Good adhesion and anti-corrosion properties. Dries quickly.
Hi-Gear. The composition is similar to liquid rubber, transparent. The mixture is expensive. Forms an even layer and dries quickly. Protects the body well.

Gravitex must be applied strictly according to the instructions.

Disadvantage: several layers must be applied.

Liqui Moly 6109. Contains polyurethane resins, which gives increased strength and elasticity. High adhesion and compatibility with various types of paint, low consumption.

Disadvantages: only black color, high price.

Types of products for gravitex processing

Today the market offers a huge number of products for gravitex processing, which are indistinguishable from each other. There are a number of characteristics according to which these funds are divided into groups.

In terms of coating durability:

— long-term gravitex coating;
— gravitex for temporary protection.

By type of container:

— aerosol, ready for use;
- an aerosol can that requires the use of a specialized gun.

By color: transparent, white, gray, black.

Nowadays, “Gravitex” exists in white, gray, black colors and in the form of a product that creates a colorless film. For the gravitex coating to be effective, it must be painted in the color of the car body.

Finally, gravitex products are relatively divided into a number of groups based on the presence of auxiliary agents in their composition. In particular, gravitex can contain anti-corrosion agents, rust converters, as well as agents for better adhesion to car body coatings.

Liqui Moly Steinschlag-Schutz

Liqui Moly anti-gravel product forms a textured surface when applied. When completely dried, the product exhibits high resistance to solvents. If necessary, it can be painted with auto enamel immediately after application, without waiting for drying.

Advantages:

resistance to temperatures from -20 to +120 °C;
can be applied to untreated or varnished surfaces;
the processed part is ready for use in 10 minutes;
Complete drying in 2 hours;
has a pleasant aroma.

Flaws:

It is undesirable to spray at sub-zero temperatures;
Sometimes the gas in the can runs out, but there is still some product left.

How to properly apply gravitex using a gun

As for cans, you need to have all the components in order to feel its benefits. Using a gun makes the process simpler and more comfortable for a person, and coating application becomes more accurate. An application gun is your choice if you are planning a long, precise process and it is important for you to treat every crevice.

Anti-gravel coating functions

Anti-gravel paint, no matter in what form it is presented, performs the following functions:

protecting the surface of the bottom, sills, bumpers and boxes from impacts of stones, dirt and moisture, preventing the appearance of cracks and rust;
sealing by sealing cracks and damage, which prevents their further increase;
increase in vibration and noise insulation properties.

We also recommend that you carefully study our specialist’s article about what Movil for cars is.

Anti-gravel body 950 instructions for use

Everyone knows body 950 anti-gravel very well. This is its next generation, the next step in anti-gravel production technology. What makes them different? The first is the rubber content.

In terms of rubber content, this composition is almost identical to rubber! Almost 80% rubber is contained in this product, which allows it to achieve amazing elasticity.

For example, we applied anti-gravel to silicone paper, then removed it and subjected it to deformation. To our great surprise, we did not find a single crack; moreover, when we tried to tear it, the anti-gravel stretched like liquid rubber.

Therefore, its anti-gravel properties are at the highest level: the pebbles are perfectly springy, and dirt is not absorbed (like body 950). In addition to all this, such an anti-gravel composition, where such an amount of rubber is excellent sound insulation.

The fact is that the elastic material perfectly “removes” vibrations from the metal. Next, on a vertical surface we will look at how “obedient” this material is in work.

To apply body 951 anti-gravel we used a spray gun from the same company

Important note. To apply this anti-gravel you must use a high-quality spray gun, always with an adjustable nozzle

Guns with a direct-flow tube will not be able to properly apply this anti-gravel.

Now we will show how anti-gravel works in various situations in which we can use it. For example, sometimes there is a need to create an even seam, like factory ones.

Under natural conditions, when we take a tube with sealant, we cannot convey this seam. The same anti-gravel, due to the fact that it allows itself to be applied in a thick layer, easily copes with the task.

Naturally, this will not be a factory seam. But it will be a very beautiful and high-quality imitation. There is an increasingly common situation (in particular with Volkswagen cars) where a thick coat of sealant is sprayed on the sills.

We can use anti-gravel body 951 to repeat this structure. It is so vertically stable that we can repeat any, even large, structure. And it will remain with us in the form in which we applied it.

Finally, we will show a test for the vertical stability of the material. We will apply it to one point. Without moving the spray gun, we can estimate the thickness of the material without dripping.

Gravitex you shouldn't be afraid of roads

The appearance of all cars deteriorates over time due to scratches, minor dents and various types of abrasions that appear due to unfortunate stones, crumbs, sand and various objects slipping from under the wheels. A minor scratch not only worsens the appearance of the car, but will also later become the epicenter of corrosion if the car is not protected in due time.

Sometimes attempts to paint over scratches fail. If you choose the wrong paint color, the car, at best, loses its pleasant appearance. Then you have to completely repaint the bumper or the entire fender and wait for the unwanted appearance of the next stone. Such problems can be anticipated if you think about gravitex protection in time. How to deal with this difficulty using products designed for gravitex processing? You will read about this in this article.

Purpose and advantage of gravitex

A car on the road is at great risk, and it is not always visible to the naked eye. For example, stones, gravel, salt, crumbs, sand and various debris that slip out from under the wheels peel off the paint in the lower areas of the car body, on wheel arches, fenders, and even more so under the bumper. This significantly distorts the overall appearance, but does not slow down the corrosion process. Over time, the situation only becomes more complicated. This often leads to problems with the machine.

The solution to the dilemma is the means by which Gravitex treatment is carried out, the so-called anti-gravel. Their special composition allows them to take on the impact of pebbles and other solid particles, absorbing it entirely, which minimizes the risk of damage to the body. When covering areas of the body that are particularly prone to risk, these products guarantee protection of the car body and paintwork from numerous adverse factors:

— prevent damage from impacts from gravel, stone chips, pieces of glass and various debris;
— guarantee the integrity of the paintwork of wheel arches, fenders, sills, the lower section of the bumper and other components of the body;
— protect particularly risk-prone areas of the body from corrosion;
— maintain the beautiful appearance of the car;
— due to their springiness, they reduce body vibration and noise levels.

All this requires the least amount of time, effort and money. Thanks to this, nowadays almost all car enthusiasts carry out gravitex treatment on their cars.

Structure and features of gravitex

All of the above features of gravitex coating are provided by its components. Often, gravitex is produced in the form of an aerosol or liquid (it is applied with a spray gun or a special-purpose gun). Gravitex consists of rubber, synthetic resins and organic solvents. When the surface is coated, the liquid dries and acquires the desired qualities.

When dried, the gravitex coating hardens, but remains elastic, its surface becomes finely lumpy, and its thickness is 1-2 mm. However, this layer is more than enough to combat road difficulties.

A huge advantage of gravitex is the permissibility of painting or enameling it in the color of the car body. However, this treatment is recommended when using some gravitex coatings, since it guarantees protection against corrosion. Since gravitex has a spongy structure, dampness sometimes reaches the metal of the car body. If its components are not an anti-corrosion agent or a rust converter, then applying paint to this surface when drying is mandatory.

Types of products for gravitex processing

In terms of coating durability:

— long-term gravitex coating;
— gravitex for temporary protection.

By type of container:

— aerosol, ready for use;
- an aerosol can that requires the use of a specialized gun.

By color: transparent, white, gray, black.

Options for using gravitex

Depending on the position of the surface to be treated, the method of applying gravitex is selected.

Steps for applying anti-gravel to painted metal surfaces:

- clean and degrease the surfaces being treated;
— use tape or another method to cover surfaces that should not be subject to gravitex application;
— using a specialized gun or spray gun, apply gravitex coating;
— remove the protective agent;
— a day must pass before the first trip;
- if necessary, paint with automotive enamel or varnish, following all operating instructions for these products.

Applying Gravitex to unpainted surfaces or to the bottom of the car requires a slightly different course of work:

- clean and degrease the surfaces being treated;
- apply the appropriate type of primer;
- if necessary, puttying is carried out;
- cover surfaces that should not be treated using tape or other methods;
— as soon as the soil has dried, apply a gravitex coating;
- after the gravitex has completely dried, paint it using automotive enamel and varnish.

Gravitex gun

A special gun for Gravitex is a device designed for applying Gravitex to a surface before painting. In general, it is used in mechanical engineering, in car services. In general, Gravitex is used in areas that are subject to intense mechanical influences, such as car sills and the lower areas of doors. It is also possible to use gravitex to treat the underbody of a car body, both from the outside and inside. As a result of drying, Gravitex acquires the characteristics of dense rubber, protecting the car body and weakening the impact of stones. Using this device, an even layer is applied to the surface. It has a comfortable handle and a soft, large trigger.

Gravitex protection is very necessary, and even more so very effective. Every motorist who cares about his favorite car wants it to maintain its sophisticated appearance longer. Such a person will definitely carry out this easy process, and will no longer be afraid of scratches and chips, which are almost inevitable in the conditions of our domestic roads.

Considering the state of current roads, it is virtually impossible to do without anti-gravel.

Low cost, simple application and reliability - all this is combined in gravitex, which for a long time forms armor for the body of your car from many inconveniences. Protected means armed!

After the rain, this place was always wet, I searched for the reason for a long time, and found it.
Somebody placed the molding unsuccessfully against the glass on the outside of the door and a hole formed and all the water flowed inside the door, and then collected there on the threshold. Here in the photo we see the diligent work of the craftsmen. Such welding work, but high-quality and with complete chemical treatment for rot and corrosion protection (high-quality! not ARA and not Kazakhs!) approximately how much does it cost you, let’s say in Moscow?

the surface where this Body 950 will be applied need to be washed with kerosene or white spirit, then apply this Body and that’s it? Or do you need to apply more paint to the anti-gravel layer from Body?

Last spring I had the imprudence to work on the wheel arches (the fight against rust, I’ll say right away that it did not end in my favor.) I cleaned the edges of the arches to bare metal (9, it seemed to me). Treated with phosphoric acid (converter), then leveled the sinks and potholes with fiberglass putty. And then (the devil pulled me) instead of paint, apply anti-gravel (matte black, made in Ukraine, bought at Auchan for 120 rubles). And on you, your little machine gun, after 3 months, rusty stains appeared!! In addition, this anti-gravel has a different color depending on the degree of humidity. Absorbs water, or what?? Don't repeat my mistake.

It seems that the anti-gravel composition is hydrophilic. When dry it is gray in color, but as soon as you wet it with water it becomes intensely black. I didn’t know about such properties, and that’s how I got caught. When it warms up, everything will have to be redone.
