Ceramic coating 9H has become a revolution in the world of car care - it protects the paintwork from scratches, chemical influences and ultraviolet radiation, giving the car a mirror shine for years. But professional processing by the service costs 30–100 thousand rubles, and the result does not always live up to expectations. Is it possible to apply ceramics 9H yourself and save money? Yes, if you know the nuances of the technology and avoid common mistakes.
In this article - step by step guide with photos, videos and expert advice: from choosing a composition to finishing polishing. We'll look at what tools you'll need, how to prepare the body, and why 90% of failures when applying ceramics are due to improper washing and degreasing. You will also learn how to check the quality of the coating after drying and how long it will last in real conditions (spoiler: not always 5 years, as manufacturers promise).
What is 9H ceramic coating and why is it better than wax or liquid glass?
Ceramics 9H is a liquid polymer based on silicon dioxide (SiO₂), which after application forms a durable protective layer 2–5 microns thick. The number “9” in the name indicates hardness on the Mohs scale (maximum 10 for diamond). For comparison: car varnish has a hardness of ~2H, and wax has a hardness of only 0.5H.
Advantages of ceramics over alternatives:
- 🛡️ Scratch protection: withstands light mechanical impacts (branches, sand, car washes).
- 🌞 UV filter: prevents paint fading and the formation of microcracks.
- 💧 Hydrophobicity: Water and dirt roll off the body, making cleaning easier.
- ⏳ Durability: When applied correctly, it lasts 2–5 years (versus 3–6 months for wax).
However, ceramics also have disadvantages: high price (from RUB 5,000 per set), difficulty in application and the need for perfect body preparation. If there are any defects on the paintwork (scratches, holograms), ceramics will not hide them, but will only highlight them.
What tools and materials will be needed: complete checklist
For self-application of ceramics 9H you will need:
Single stage or two stage polishing machine (e.g. Makita 9237CX3 or Flex XFE 7-15 150>)
Polishing wheels of different hardness (yellow, orange, black)
Abrasive pastes (3M Fast Cut Plus, Menzerna Power Finish)
Degreaser (CarPro Eraser or isopropyl alcohol 99%)
Lint-free microfiber cloths (The Rag Company)
Applicator for applying ceramics (foam rubber or suedo)
Infrared lamp or heat gun (to speed up polymerization)
Protective gloves and respirator (ceramic fumes are toxic!)
-->
Also prepare a place to work: a clean garage with good lighting, free from dust and drafts. The air temperature should be 18–25°C, humidity - no higher than 60%. At a lower temperature, ceramics will polymerize less well, and at a high temperature, they will dry too quickly, leaving streaks.
⚠️ Attention: Do not use household hair dryers instead of a heat gun - they do not provide uniform heating, which leads to uneven polymerization of the coating.
Body preparation: washing, degreasing and polishing
This is the most important stage - 90% of success depends on preparation. If you skip even one step, the ceramics will lie unevenly or peel off after a few months.
Step 1: Washing and decontamination
Start with contactless car wash under high pressure (eg Kärcher K7) to remove coarse dirt. Then:
- Apply car shampoo with pH-neutral formula (for example, CarPro Reset) and wash the car by hand with a microfiber mitt.
- Treat the body clay bar (Nanolex Clay) with lubricant spray to remove bitumen and industrial contaminants.
- Rinse the machine again and dry with a lint-free towel or blower.
Step 2: Degreasing
Use a specialized degreaser (CarPro Eraser, Gyeon Prep) or isopropyl alcohol 99%. Apply the product to a microfiber cloth and wipe the body in small areas, avoiding circular motions (to avoid leaving holograms).
To check the cleanliness of the surface, put on latex gloves and run your finger over the body. If you hear a squeak, there are still contaminants, you need to repeat degreasing.
Step 3: Polishing (if necessary)
If the paintwork has scratches, holograms or oxidation, polishing is required. Use:
- 🔵 Abrasive paste (for example, Menzerna FG400 for deep defects).
- 🟡 Final paste (Poorboys SSR2.5) to restore gloss.
- 🔴 Polishing wheel medium hard (orange for 3M or yellow for Lake Country).
Polish at speed 1200–1800 rpm, holding the machine at an angle of 45° to the surface. After polishing, degrease the body again!
What happens if you apply ceramics to an unpolished body?
Ceramics will not hide paintwork defects, but will only fix them. Scratches and holograms will become even more noticeable due to the increased gloss depth. In addition, the coating may peel off in areas with wax or silicone residues.
9H ceramic application technology: step-by-step instructions
Now we move on to the most important stage. Important: work in protective gloves and respirator — ceramic fumes are harmful to health.
Step 1: Apply the first layer
Shake the ceramic bottle (Ceramic Pro 9H, Gyeon Ceramic Coating, Nanolex Si3D) and apply a few drops to the applicator. Work in small sections (50×50 cm), so that the coating does not have time to dry.
- 🔄 Apply with cross-shaped movements (first horizontally, then vertically).
- ⏱️ Waiting time before removing excess -
30–60 seconds(check the instructions for your composition!). - 🧹Remove excess clean microfiber without pressure, moving in one direction.
Step 2: Polymerization
After applying the first layer, the coating should polymerize. Depending on the composition, it takes from 12 to 24 hours. You can speed up the process using:
- 💡 Infrared lamp (keep at a distance of 30–50 cm, 10–15 minutes per area).
- 🔥 Heat gun (temperature
40–60°C, no higher!).
⚠️ Attention: If polymerization occurs unevenly (for example, one side of the car is in the shade), the coating may be obtained with varying degrees of hardness and hydrophobicity.
Step 3: Apply a second coat (optional)
Some manufacturers (for example, Ceramic Pro) it is recommended to apply 2 layers for enhanced protection. The second layer is applied through 1–2 hours after the first, using the same technology. However, remember: Excess ceramic does not increase protection, but only wastes material.
The optimal coating thickness is 2–3 microns. More does not mean better: a thick layer takes longer to dry and may crack.
Common mistakes and how to avoid them
Even experienced detailers make mistakes when working with ceramics. Here are the most common:
| Error | Consequences | How to avoid |
|---|---|---|
| Application to a dirty body | The coating peels off after 1–3 months | Thorough washing, decontamination, degreasing |
| Working in high humidity | Formation of white spots (efflorescence) | Control humidity (max. 60%) |
| Using dirty napkins | Micro scratches on fresh surfaces | Change napkins every 2-3 panels |
| Failure to comply with holding time | Uneven polymerization, streaks | Strictly follow the manufacturer's instructions |
Another common problem is "rainbow effect" (holograms after polishing). It occurs if:
- 🌀 The circle used was too hard.
- 🔥 Polishing was carried out at high speeds (>2000 rpm).
- ☀️ The work was carried out in direct sunlight.
To eliminate holograms, re-polish problem areas final paste (for example, Jezz RN3.01) and a soft circle.
Car care after applying ceramics
9H ceramics do not make the car invulnerable - it requires proper careto last the stated 2–5 years. Here are the basic rules:
First 7 days: curing period
At this time, the coating gains maximum hardness. Prohibited:
- 🚿 Wash your car (even contactless!).
- 🌧️ Keep in the rain or snow.
- 🧴 Apply waxes, silicones or other protective compounds.
Further care
After curing:
- 🧼 Wash your car pH-neutral shampoo (for example, CarPro Reset).
- 🛡️ Apply once every 3-6 months enhancing spray (Gyeon Ceramic Detailer).
- 🚫 Avoid car washes with brushes - they even scratch ceramics.
To remove stubborn contaminants (bitumen, bird droppings), use special cleaners (CarPro TarX), but not abrasive sponges!
To test the hydrophobicity of the coating, drop water on the hood. If the drop holds its shape and rolls off easily, the ceramics are fine. If it blurs, it’s time to apply a reinforcing layer.
How much does 9H ceramics cost and where to buy it?
Prices for ceramic coatings range from 5,000 to 30,000 RUR per set, depending on brand and volume. Here are popular options:
| Brand and model | Volume | Price (2026) | Service life |
|---|---|---|---|
| Ceramic Pro 9H | 50 ml | ~12 000 ₽ | 3–5 years |
| Gyeon Ceramic Coating | 30 ml | ~8 500 ₽ | 2–4 years |
| Nanolex Si3D | 50 ml | ~9 000 ₽ | 3–5 years |
| Koch Chemie 1K-Nano | 100 ml | ~7 000 ₽ | 1–2 years |
It is better to buy ceramics from official dealers or trusted online stores (for example, Detailing.ru, Autodetailing.shop). Avoid AliExpress and markets - they often sell fakes with low content SiO₂.
⚠️ Attention: Cheap ceramics (up to 3,000 ₽) typically contains less than 20% silica and lasts no longer than liquid glass. Focus on the composition: high-quality coatings have70–90% SiO₂.
FAQ: Frequently asked questions about 9H ceramics
Can ceramic be applied to matte or vinyl flooring?
Yes, but requires special ceramics for vinyl or matte surfaces (eg. Ceramic Pro Vinyl or Gyeon Ceramic Coating Matt). Regular 9H ceramic will make the vinyl look glossy and may cause peeling.
How many layers of ceramics are optimal for a daily driver?
Sufficient for most cars one layer. The second layer is only suitable for premium or sports cars that are frequently washed and polished. Three or more layers are a marketing ploy that does not provide a real increase in protection.
How to remove ceramics if it is applied crookedly?
The only way is abrasive polishing (paste Menzerna FG400 + hard circle). This removes 1-3 microns of paintwork, so it is better to entrust the process to professionals. The alternative is to wait for normal wear and tear (1-2 years).
Can ceramics be applied to new cars with factory wax?
No! Factory wax (for example, on Toyota or Hyundai) must be completely removed using degreaser or solvent based cleaner (CarPro Tar Remover). Otherwise, the ceramics will not adhere to the varnish.
Is it true that ceramics protect against chipping?
Ceramics does not protect against chips from stones or road accidents - its hardness (9H) concerns only scratches. To protect against chipping you need PPF film (polyurethane protection) or armored glass.
