In the modern world car body is subjected to enormous loads. Road chemicals, small stones, ultraviolet radiation and dust leave an indelible mark on the paintwork, turning a once shiny car into a dull reminder of its former beauty. That is why owners are looking for ways to protect themselves, and one of the most popular solutions has become quartz coating, which is often confused with ceramics, but which has its own unique characteristics.
This material is a silicon dioxide-based liquid glass that creates a durable crystalline film on the surface. It not only hides minor defects, but also really repels dirt, water and reagents. Unlike traditional waxes, which wash off after a few washes, quartz protection lasts for months, maintaining deep color and mirror shine.
However, before you take money to a detailing center or buy a jar of composition for self-application, it is worth understanding the essence of the technology. What's really behind the marketing promises? Is this really a panacea for scratches or just an expensive way to wash your car? Let's dive into the technical details.
Chemical composition and principle of action
The basis of any high-quality quartz composition is SiO2 (silicon dioxide), which occurs naturally as quartz. Liquid polishes use nanoparticles of this substance, which, after application and polymerization, form a hard but elastic network. This mesh chemically bonds to the paintwork, creating an additional protective layer.
Unlike ceramic compounds, where silicon carbide is often used (SiC) for maximum hardness, quartz strikes a balance between durability and visual impact. Hydrophobic properties are achieved due to low surface adhesion: water does not spread, but collects into large drops that roll off, taking dust and dirt with it.
It is important to understand that “liquid glass” is not just a name, but a description of a physical process. When dry, the solvent evaporates and the solid particles fuse into a monolithic structure. That's why quartz coating so effectively resists aggressive environments.
⚠️ Attention: Despite the high hardness after polymerization, the freshly applied composition is extremely sensitive to moisture and dust in the first 12-24 hours. Violation of the drying temperature conditions can lead to clouding of the layer.
Key benefits of body protection
Why do drivers choose this method? First of all, we are talking about preserving the presentation of the car. Deep color and the rich shine that quartz gives visually rejuvenate the car. The “wet body” effect is maintained even in dry weather, which is especially appreciated by aesthetic lovers.
The second important aspect is chemical inertness. The film protects the varnish from oxidation under the influence of ultraviolet radiation and prevents paint fading. In addition, it creates a barrier to bird droppings and tree resin, which under normal conditions quickly corrode the varnish.
The third point is ease of care. Thanks to the antistatic effect, dust sticks to the body less. And if the car gets dirty, you can simply rinse it with water from a hose to wash off the main dirt. This saves time and money on car washes.
- 💎 Aesthetics: Increased color depth and the appearance of a mirror shine.
- 🛡️ Protection: Barrier from reagents, ultraviolet radiation and minor mechanical influences.
- 💧 Hydrophobic: Self-cleaning effect and quick drying of the body.
Comparison with ceramics and wax
Many people confuse quartz, ceramics and wax, considering them synonymous. This is a mistake. Car wax is a carnauba or synthetic based product that gives great shine but only lasts 1-2 months. It is quickly washed off with alkaline shampoos.
Ceramics (Ceramic Pro, Gyeon and analogues) is one step higher in hardness and durability (up to 3-5 years), but requires ideal body preparation and is difficult to apply. Quartz occupies the niche of the “golden mean”. It is harder than wax, but softer than ceramic, which makes it more forgiving when applied.
If ceramics are armor, then quartz is a dense, elastic jacket. It hides small “cobwebs” (piles) better due to its structure, while hard ceramics can only preserve them. The choice depends on what result you want to get and how much you are willing to spend.
| Parameter | Car wax | Quartz coating | Ceramics |
|---|---|---|---|
| Service life | 1-2 months | 6-12 months | 2-5 years |
| Hardness | Low | Average | High |
| Hydrophobic | Weak | High | Maximum |
| Difficulty of application | Low | Average | High |
Body preparation before application
The quality of the result depends 80% on preparation. Apply quartz composition You can’t apply it to a dirty or damaged surface—you simply comment out the defects and they will become even more visible. The process begins with a thorough two-phase wash.
After washing, chemical and mechanical cleaning must be carried out. Chemicals remove bitumen stains and metal dust, and claying (using a clay mitt or block) removes stubborn dirt, making the surface smooth as glass. Without this step, adhesion will be compromised.
The final stage of preparation is polishing. Even if there are no obvious scratches on the car, machine polishing with an abrasive paste removes the oxide layer and small scratches. Only the primer is applied to a perfectly clean and grease-free varnish, and then the quartz layer.
☑️ Preparation checklist
DIY application technology
If you decide not to contact professionals, you will need a perfectly clean, dry and warm room (garage). Dust and drafts are the enemies of the process. The temperature should be in the range from +15 to +25 degrees Celsius. Air humidity also plays a role: too high will slow down polymerization, too low will speed it up, which will lead to difficulties with polishing.
Application occurs using special applicators (microfiber or suede cloths). The composition is distributed in a thin layer with cross movements. The main mistake beginners make is applying too thick a layer. Quartz must lie in a thin film, otherwise it will not fit into the crystal lattice correctly.
The most critical moment is the moment of removing excess. After application, you need to wait a certain time (usually 3-5 minutes, depending on the brand) until the composition begins to matte. At this point, you need to gently rub it with a clean microfiber until the streaks completely disappear. If you leave it too long, the composition will “stand up” and it will be extremely difficult to remove it.
⚠️ Attention: Work only in good side lighting. In the dark or in poor light, you will not see where the greasy stains from the composition remain, which, after polymerization, will turn into irremovable stains.
The secret of professionals
Use several clean microfiber towels. As soon as one stops sliding along the body or begins to “smudge,” immediately replace it with a new one. Saving on rags is unacceptable here.
Coating care and service life
After application, the machine requires time to fully cure. Usually this is from 7 to 14 days. During this period It's better not to wash the car and do not leave it in the rain. If it rains in the first hours, don’t panic, just let the car dry naturally without wiping it.
To extend the life of the coating, it is recommended to use special shampoos with neutral pH and additives that support hydrophobe. Aggressive chemistry in self-service car washes (active foam with a high alkali content) gradually destroys the protective layer, reducing its lifespan.
Once every 2-3 months you can apply an activator spray or “quick ceramic/detailer” after washing. This refreshes the hydrophobic properties and adds shine. With proper care, the quartz coating retains its properties for up to a year, after which the procedure can be repeated without completely removing the old layer (only by washing and degreasing).
- 🚿 Washing: Use only soft sponges and non-contact chemicals.
- 🧴 Activators: Apply treatment sprays once a month to restore the effect.
- 🚫 Limitations: Avoid hard brushes and abrasive pastes during use.
Carry a quick-drying spray for glass and bodywork in your trunk. If drops of water remain after washing, they can be quickly removed without leaving streaks, which is critical for preserving the hydrophobe.
The durability of the coating directly depends on the frequency and quality of washing: aggressive chemicals kill the protection faster than time.
Is the game worth the candle: final analysis
Coating a car with quartz is not magic, but a chemical process that actually works. It will not make the body immortal, but it will make life much easier for the owner. The car stays cleaner longer, looks brighter and better resists the aging of the paint.
However, you shouldn’t expect that insects will stop sticking to your car or that it will become bulletproof. This is a trade-off between maintenance cost and visual impact. For new cars or cars in excellent condition, this is a great way to preserve their value.
If you are ready to take care of your car, wash it with the right products and periodically renew the coat, you will be pleased with the results. If you plan to wash your car once every six months at the first car wash you come across with a brush, quartz will only waste your money.
⚠️ Attention: Do not believe the promises of “eternal coverage”. Any chemistry has its own resource, and quartz is no exception. After a year, the hydrophobe will begin to weaken, and this is normal.
Is it possible to apply quartz over old faded varnish?
Technically it is possible, but there is little point in it. The coating will only highlight defects and will not restore color. First, restorative polishing is necessary, which will remove the oxidized layer, and only then does it make sense to apply protection.
How many layers of quartz can I apply?
Usually apply 1-2 layers. Applying the third and subsequent layers does not make practical sense, since adhesion is reduced, and this will not add a visual or protective effect. The first layer acts as a primer, the second as the main one.
Will the coverage affect the cost of the CASCO policy?
By itself, no. However, if you obtain a certificate for application at a specialized center, some insurance companies may offer a discount on CASCO, since the risk of damage to the paintwork and the cost of restoration are reduced.
Do I need to polish my car after applying quartz?
No, you cannot polish the coating. Abrasive polishes will remove the protective layer. If scratches appear on the coating, you can try to mask them with special “fillers”, but full polishing is possible only after the quartz layer is completely removed.
