Protection of the paint coating of the car is not just a desire to preserve the shine, but a necessary measure to extend the life of the body. Ceramic coating with hardness 9H It has become the gold standard in child-selling, offering unrivaled resistance to chemistry and micro-scratches. Many car owners wonder whether it is possible to apply such a composition yourself in garage conditions.
The process requires not only high-quality materials, but also strict adherence to technology. Mistakes in the preparation or application phase can lead to divorces that will have to be cleaned with abrasive polishing. In this article, we will take a look at each step of the work, from washing to final polymerization, so you get the perfect result.
The main advantage of ceramics before wax or silant is the durability and physical strength of the layer. However, ceramic It is not a “armour” in the literal sense of the word, it only increases the threshold of damage to the varnish. Proper application guarantees a hydrophobic effect and a deep body color for up to three years.
Surface Preparation: The Foundation of Durability
Any work with protective compounds begins with thorough cleaning. On the body should not remain dirt, bitumen spots or traces of insects. Ignoring this stage will lead to the 9H ceramics It will seal the dirt under itself, and then it will be impossible to remove it without removing the entire layer of protection.
The first thing to do is wash the car in a contactless way using active foam. This will allow to soften the bulk of the contaminants without mechanical contact. Then, a manual wash using two buckets and microfibers to minimize the risk of new scratches.
After the main wash, chemical cleaning is necessarily carried out. For this purpose, special means are used to remove metal shavings and iron oxides, which often remain on the body after braking or moving along the track. The reagent changes color when it comes into contact with the metal, signaling the start of the reaction.
- 🚿 Conduct a thorough two-phase washing of the body.
- 🧪 Treat the surface with antibitum and metal remover.
- 🧽 Use a clay sponge or clay to remove ingrained contaminants.
- 💨 Blow all the gaps and joints with compressed air.
The final touch of preparation is degreasing. Even if the surface seems clean, it is left with silicones from shampoos or polishes. Antisilicone or isopropyl alcohol guarantee maximum adhesion (adhesion) of the ceramic composition with the varnish.
⚠️ Warning: Never apply ceramics on a hot body or in direct sunlight. The composition will start to dry instantly, which will lead to irremovable divorces and stains.
Abrasive polishing: elimination of defects
Ceramics do not hide defects, but emphasize them. If there are scratches, holograms or scuffs on the body, after applying protection, they will become even more noticeable. Therefore, the polishing step is critical to obtaining a mirror effect.
The process is divided into two main stages: recovery and finishing. First, an abrasive paste is used to remove the defective layer of lacquer. Then apply a polymer with less abrasive or without it to create gloss. It is important to work in stages, not missing the plots.
To work, you will need a polishing machine, preferably orbital-rotary, as it is safer for beginners. Circles are selected depending on the stiffness of the varnish and the degree of damage. Polishing requires skill, so it is better to practice in an inconspicuous area.
How do you know if the polishing is complete?
The defects disappeared, the surface became smooth and glossy. When carrying out with a finger (in a glove), there should be no roughness. The inspection is carried out under bright light.
After polishing, it is necessary to remove the dust formed in the process. To do this, the body is repeatedly washed or thoroughly blown with compressed air, and then again pass with a degreasing agent. Only then can the main stage be started.
Technology of application of ceramic composition
Application 9H ceramics It is a piece of jewelry that requires attention to detail. The composition usually comes in a vial with an applicator or requires application to a special napkin. It is important to work in a clean, well-lit room with a temperature of +15 to +25 degrees.
Apply the composition in small areas, about 50 by 50 cm. The movements should be cross-sectional: first along, then across, to ensure uniform distribution. Do not press hard on the applicator, the layer should be thin and barely noticeable.
Pay special attention to the time of the exhibition. Different compositions have different maturation times before polishing. It's usually 5 to 15 minutes. If you overstay it will become too hard and it will be difficult to remove.
☑️ Checklist of application
Use clean, dry high quality microfibers to polish. Change the side of the napkin or take a new one as soon as it becomes wet from the composition. It is critically important not to let the composition dry completely before polishing.Otherwise, you will have to re-paint the layer after grinding.
| Parameter | Meaning/Description | Impact on outcome |
|---|---|---|
| Temperature. | +15...+25 °C | Optimal Polymerization Rate |
| Humidity | Not more than 70% | High humidity slows down drying |
| Expenditure | 30-50ml in the car | Depends on the number of layers |
| Time to dry | 1-2 hours (between layers) | It's necessary to grasp. |
Drying and polymerization of coatings
After the application of the main layer, the polymerization process begins. At this time, the composition gains its hardness and chemical resistance. The car should stay in a dry room for at least 12 hours, or better 24 hours.
Do not let moisture get on the body in the first 24 hours. Rain or dew can disrupt the structure of the forming layer, leaving stains or matteness. If the car was outside at night, a slight correction may be required in the morning.
Some formulations require multiple layers to achieve the stated hardness 9H. The second layer is usually applied 1-2 hours after the first one, when the solvent has completely evaporated. This increases the thickness of the protective film and enhances the hydrophobe.
Use infrared drying to speed up the process. Heating to 60 degrees for 30 minutes allows you to completely polymerize the coating in one session, increasing its resistance.
Complete crystallization of the composition takes about 7-14 days. During this period, it is not recommended to wash the car with chemicals or use automatic washing with brushes. Give the coating time to gain maximum strength.
⚠️ Please do not apply the second layer if the first one has not dryed. This will lead to the dissolution of the lower layer and the appearance of greasy spots that cannot be removed without polishing.
Ceramics care and extension of service life
Even the most durable coating requires proper care. Ceramics 9H It is resistant to chemistry, but aggressive alkaline shampoos can gradually reduce hydrophobic properties. Use neutral means for regular washing.
To maintain the effect, it is recommended to apply a ceramic activator or spray care once every 2-3 months. Such means refresh the hydrophobe and fill the micro scratches that occur during operation. This prolongs the life of the main layer.
Avoid using rough sponges and brushes. The best friend of ceramics is soft microfibre and the two-bucket method. Regular washing prevents the formation of a persistent plaque, which is more difficult to wash from a protected surface.
- 🧴 Wash your car with a pH neutral shampoo.
- 🚫 Avoid compositions containing wax or oils.
- 🧼 Use a separate bucket for wheel arches.
- 🌧️ Remove bird droppings and tree sap in a timely manner.
Compliance with these simple rules will preserve the shine and protection throughout the life of the coating. Ceramics is an investment in the look of a car and it pays off with the right attitude.
9H ceramics are not perpetual coatings, but consumables with a long service life that require careful care to preserve properties.
Frequent mistakes when applying independently
Beginners often make mistakes that negate all efforts. The most common of these is insufficient degreasing. If there are traces of polishes on the varnish, the ceramics simply will not lie evenly.
The second mistake is to apply a layer that is too thick. Many people think that the more composition, the better the protection. In practice, the excess turns into a sticky film that is difficult to polish, and iridescent divorces remain.
The third mistake is saving on expenses. Cheap wipes can leave a pile or scratch the varnish. Low quality applicators distribute the composition unevenly. Use only professional equipment.
⚠️ Note: If you notice divorces after application, do not try to wipe them by force immediately. Let the composition stand for 10-15 minutes, then gently polish the clean side of the microfiber.
It is also worth mentioning work in poor lighting. In a dark garage, you can’t see where the lineup is left and where it’s gone. Use powerful LED lights or work in daylight.
What to do if the ceramics are stained?
If the spots appear immediately, try polishing the area with a microfiber soaked in a polished spray. If the composition has already been polymerized, only abrasive polishing of this site will help.
Comparison of ceramics with other types of protection
To understand the value 9H ceramicsLet's compare it to the alternatives. Wax coatings give excellent shine, but last only 1-2 months. Silantes last longer, up to 6 months, but do not provide such hardness.
Liquid glass is an intermediate option. It is cheaper than ceramics, easier to apply, but its hardness is usually 5H-7H. Ceramics benefit in durability and chemical resistance, withstanding a more aggressive environment.
The film (anti-igravium) protects against chipping better than any chemistry, but is much more expensive and more difficult to apply. Ceramics are ideal for protection against burnout, chemical reagents and ease of washing.
Should I put ceramics on an old car?
Yes, if the paintwork has retained the depth of color and does not have strong corrosion. Pre-polishing will return the shine, and the ceramics will protect the residual life of the varnish from further destruction.
Can I apply ceramics over the wax?
No, it's useless. Ceramics will not be able to clutch wax and just drain or gather in drops. The surface should be completely clean and defatted.
How many layers of ceramics is optimal?
For most compositions, 1-2 layers are enough. Applying more layers does not give a multiple increase in protection, but only increases material consumption and the risk of defects.
How to verify the authenticity of 9H hardness?
At home, this is difficult to do. 9H hardness is a marketing designation that means high scratch resistance, but not absolute scratchability. The actual test can only be done in the laboratory.
Do I need to polish the car before each application?
When updating the coating after a year or two, a full polish is not always necessary. It is enough to make a light cleaning polish or use abrasive clay, if there are no deep defects.
