In pursuit of the perfect shine of the body, car owners are increasingly paying attention to modern protective compounds, including liquid quartz occupies a special place. This service has become a popular alternative to classic polishes and expensive ceramics, offering a balance between price, quality and durability of the coating. Many drivers, when stopping at a regular car wash, do not even suspect that the “quartz” offered there can be radically different in composition and properties from what is applied in specialized detailing centers.
The essence of the technology is to create a thin layer of silicon dioxide on the surface of the paint and varnish coating, which provides a hydrophobic effect and protection from an aggressive external environment. Applying quartz on a sink is often positioned as an express service that takes no more than an hour, which raises questions among sophisticated car enthusiasts regarding the depth of penetration of the composition. Unlike multi-stage ceramics, which require several stages of preparation, quartz sink compounds are designed for quick application, but this does not make them useless.
Understand the intricacies of the procedure, differences from wax and understand when it is really necessary update the protective layer with quartz composition, a detailed analysis of the technology will help. It is important to understand that the result directly depends not only on the chemistry, but also on the quality of the preliminary preparation of the body, which at fast washes is often carried out on a residual basis.
What is liquid quartz and how does it work?
Liquid quartz is a polymer composition, the main active component of which is silicon dioxide (SiO2). Upon contact with air and the surface of the body, a polymerization reaction occurs, resulting in the formation of a durable, transparent film. This film fills the microscopic pores of the varnish, creating the effect hydrophobicity, due to which water rolls off the body, taking dust and dirt with it.
Unlike traditional waxes, which simply lie on the surface and are washed off after 3-5 washes, quartz forms more stable chemical bonds with paintwork. However, it is worth distinguishing between professional compositions that require complex preparation and drying in a chamber, and those that are used in streaming car washes. The latter are often hybrid solutions that combine silicones and quartz components to achieve a quick visual effect.
The protection mechanism is based on the high density of the molecular lattice of the frozen composition. It prevents acid rain, chemicals and bird droppings from penetrating the car's paintwork. Glossy effect, which drivers value so much, is achieved by leveling the surface microrelief, which improves light reflection.
Chemical basis of the composition
Most quartz coatings are based on tetraethoxysilane or its derivatives. It is these substances that, when they evaporate, leave a hard layer of silicon dioxide on the surface, which is comparable in hardness to sand, but in a microscopic layer it is elastic and does not scratch the body.
Differences between quartz and wax and full ceramics
There is confusion in the car care services market, and often the customer is offered “ceramics” at the car wash, which in fact is an ordinary quartz spray. In order not to overpay, you need to clearly understand the difference between the three main types of protection. Wax - This is the cheapest and short-lived option, creating a greasy film that lasts for at most two weeks.
Quartz coating (in the format of a car wash service) is the “golden mean”. It provides protection for 6 to 12 months, is excellently hydrophobic and has deep color. Full ceramics (9H and higher) is applied only in detailing centers, costs 5-10 times more, requires polishing the body before application and provides protection for 2-3 years, but it is less elastic and can chip on impact.
The main advantage of quartz over wax is its resistance to chemicals and temperature. Wax (wax) can run on a hot hood in the summer or be washed off with an alkaline shampoo. Quartz easily withstands heat and contact with most car shampoos. However, unlike expensive ceramics, quartz from the sink will not save you from serious mechanical damage or deep scratches.
- 🚗 Durability: Wax lasts 2-3 weeks, quartz on the sink - 6-8 months, professional ceramics - up to 3 years.
- 💧 Hydrophobic effect: In wax it is weak and quickly disappears, in quartz it is pronounced and stable throughout its entire service life.
- 💰 Cost: Quartz is much more affordable than ceramics, but more expensive than regular waxing in terms of service life.
Quartz on a sink is a compromise solution: it gives 80% of the effect of expensive ceramics for 20% of its price, but requires more frequent updating.
Application technology for automated washes
The process of applying a protective composition on modern complexes is usually automated and occurs at the final stage of washing. After the main cycle of washing away dirt and foam, when the car is drying or driving slowly, the nozzles spray the active composition. The whole process takes a few minutes and does not require human intervention.
There are two main methods of application: contact and non-contact. In the first case, soft brushes are used that rub the composition into the paintwork, which theoretically improves adhesion, but carries the risk of “cobwebs” appearing on dark cars. Non-contact method (soft touch) is safer for varnish, but requires ideal water chemistry and a very precise dosage of the reagent.
It is important to understand that the body must be perfectly clean before spraying quartz. If the washing does not include the stage of active foam or manual finishing of hard-to-reach places, the effectiveness of quartz is reduced. The dirt remaining in the pores will not allow the composition to take hold, and it will be washed off after the first trip in the rain.
Body preparation: critical stage
The quality of the final result depends 70% on preparation. Even the most expensive quartz composition will not adhere to a greasy film or layer of bitumen stains. At specialized car washes, they often offer a service before applying protection. decontamination — removal of metal inclusions and bitumen with special cleaners.
If you plan to apply protection, make sure the car has been through a hand wash or a quality active foam. Simply passing under a high-pressure jet will not remove all contaminants. Particular attention should be paid to cleaning wheel arches and the lower parts of the rapids, where the concentration of dirt is maximum.
⚠️ Attention: Applying quartz to an uncleaned body will seal dirt under a layer of polymer. This will not only deprive the car of its shine, but can also provoke corrosion in chipped areas, since moisture will be preserved under the film.
Ideal preparation also includes drying the body before application, if the technology requires it. Some compounds are applied to a wet surface, others - strictly to a dry surface. At automatic car washes this parameter is controlled by the program, but at manual stations it is worth checking that the technician does not start polishing a car wet with mud.
☑️ Control of preparation for application
Comparison of efficiency and cost of services
The economic feasibility of choosing quartz is obvious when compared with regular visits to the car wash without protection. A car with a treated body gets dirty less, which allows you to increase the intervals between washes or switch to cheaper express options.
Below is a comparative table of the various types of coatings available on the services market:
| Parameter | Carnauba wax | Liquid quartz (wash) | Ceramics (Detailing) |
|---|---|---|---|
| Service life | 2-4 weeks | 6-9 months | 24-36 months |
| Hydrophobic | Medium | High | Maximum |
| Price (average) | 300-500 rub. | 1000-2500 rub. | 15000-40000 rub. |
| Scratch protection | Missing | Minimum | High (microhardness) |
It is worth considering that the price at a car wash may vary depending on the class of the car and the brand of chemicals used. Popular brands like Koch Chemie, Grass or Shafite have established themselves as reliable suppliers of compositions for the mass market.
Order quartz application in late fall, before the start of the winter season. This will help protect the body from reagents and salt, which are most aggressive in the cold season.
Car care after treatment
After applying the protective layer, the rules for car care change. The main rule is to avoid aggressive chemicals. Alkaline shampoos, which are often used in cheap car washes to remove heavy dirt, can destroy the structure of quartz faster than expected.
It is recommended to use a two-phase wash: first wash off the main dirt with water, then apply a pH-neutral shampoo. Drying also plays a role: using rough rags or felt mittens can leave micro-scratches on the protective layer itself, although the varnish underneath will remain intact.
Periodically, approximately once a month, it is recommended to use activator sprays (quick detailers) containing SiO2. They refresh the hydrophobic effect and extend the life of the base coating. Do not scrub the body with abrasive sponges or use “all stain removers” containing solvents.
⚠️ Attention: If you notice that the water has stopped rolling into “balls” and is simply spreading over the body like a film, then the resource of the quartz layer has been exhausted. Re-processing required.
Frequently asked questions (FAQ)
Is it possible to apply quartz to an old car with scratches?
Yes, you can. Quartz will not hide deep scratches, but it will preserve them and prevent oxidation of the metal in the chipped areas. However, for a better visual effect, it is advisable to undergo a light polishing before application to remove the “cobwebs”.
Is quartz composition harmful to rubber bands and plastic?
Modern compositions for automatic car washes (soft paint) are safe for rubber, plastic and chrome, provided the washing technology is followed. Problems can only arise if the concentrate gets on the glass (leaves rainbow stains) or if the composition dries on the surface before washing.
How often do you need to renew the coating on your sink?
On average, the effect lasts from 15 to 25 wash visits or about 6-8 months of use. The frequency depends on the storage conditions of the car (garage or street) and the intensity of use.
Will quartz protect against sandblasting on the highway?
No, the thin polymer layer is not armored film. It will not save you from impacts from gravel and sand at high speeds; for this you need a polyurethane anti-gravel film. Quartz protects only from chemicals and ultraviolet radiation.
Is it possible to wash a car with quartz using a touchless car wash?
Yes, it is possible and necessary. Touchless washing is even preferable, as it minimizes the risk of new scratches. The main thing is to choose sinks that use high-quality chemicals and well-filtered water so as not to leave streaks.
