In an era when the prices of professional deli- machining reach the heights of space, many car owners are thinking about self-application of protective coatings. Liquid pottery, or as it is often called, liquid glassIt has become a real trend that allows to give the body a deep shine and hydrophobic properties without resorting to masters. However, this process requires not only financial investments in materials, but also serious preparation, patience and understanding of the physicochemical processes occurring on the surface of the paint coating.
Many enthusiasts mistakenly believe that it is enough to simply buy a bottle of the composition and wipe the car with it, but reality dictates its own harsh conditions.
The quality of the final result depends on 80% of how thoroughly the preliminary cleaning and degreasing of the surface was carried out.
If you miss the step of deep cleaning of pores, the ceramic layer will lie unevenly, and in some places may simply not polymerize, which will lead to stains and stains.
In this article, we will discuss in detail the entire technological process, which will allow you to get a result close to professional, while saving a significant amount.
You will learn how different types of trains, what tools are really needed, and what you can do without, and how to avoid fatal mistakes that can spoil the appearance of your car.
Composition selection: applied ceramics against liquid glass
The first step in any body protection project is to choose the right chemistry. The market is oversaturated with offers, and it’s easy for a beginner to get confused about marketing titles and promises.
The main difference lies in the chemical basis: professional ceramics based on silica (Silicon dioxide).SiO2) provides hardness and durability, whereas silane-based budget options are more often a temporary solution.
The service life of professional formulations can reach 2-3 years, while simple spray sealants are washed off after 3-6 months of operation.
When choosing a product, pay attention to the concentration of the active substance, which is often indicated in percentages, although this figure may be conditional.
The thicker formulations require perfect surface preparation and are often applied in several layers with intermediate drying, which increases the laboriousness of the process.
For the first experience, it is better to choose formulations with less polymerization time, as they forgive more errors in polishing.
The secret to SiO2 concentration
High concentrations of silica (90% or higher) do not always mean better quality. Often, such compositions are too quickly grasped, leaving the removed divorces (hols) on a dark varnish. The optimal balance for self-application is compositions with a SiO2 content in the region of 60-70%.
- 🧪 Professional ceramics - requires strict compliance with temperature and humidity, provides maximum hardness.
- 💧 Hybrid coatings combine the properties of wax and ceramics, are easier to apply, but have a lower durability resource.
- 🚿 Ceramics for washing - added to the water during finishing rinse, serves as an express care between the main treatments.
Necessary tools and organization of the workplace
The success of the operation depends on the conditions in which you will work. The ideal option is a specially equipped box with a controlled temperature and no dust, but at home you can do and garage.
The main enemy when applying ceramics is direct sunlight and high body temperature, which cause the composition to dry instantly, leaving no time for high-quality polishing.
It is also critical to ensure good lighting, it is advisable to use cold light LED lamps to see all defects and stains.
Use several light sources, directed at different angles. This will allow you to see the "holograms" and the remains of the composition, which in direct light may not be noticeable.
As for the tools, you won’t need complex equipment, but the quality of applicators and wipes plays a crucial role.
Cheap microfibers can leave micro scratches on a newly treated surface, negating all polishing efforts.
Be sure to prepare gloves and a respirator, as the pairs of some solvents and the ceramic suspension itself can be harmful to the airways.
- 🧤 Nitrile gloves - are required to protect the skin of the hands from aggressive chemical compositions.
- 🧽 Applicators - it is better to use suede or special sponges with microfibre, complete with the composition.
- 🧻 Microfiber wipes You will need tight towels for the initial removal and soft polishing wipes for the finish.
Stages of body preparation: the basis of durability
Surface preparation takes up to 70% of the total operating time, and neglecting this stage is the main reason for failure.
A simple shampoo wash is not enough here, since bitumen spots, metal dust and ingrained contaminants remain on the surface, which are not removed by alkaline chemistry.
The first thing you need to do is to conduct a deep cleaning with clay or a synthetic analog to pull the dirt from the pores of the varnish.
☑️ Checklist of preparations
After mechanical cleaning, a chemical depotaminization step follows, which removes brake dust and rust particles.
If there are static contaminants on the body that are not removed by clay, light abrasive polishing may be required.
The final and most important chord of preparation is degreasing, which removes any traces of oils, polyroles and silicones.
| Phase | Purpose | Materials | Drying time |
|---|---|---|---|
| Washing | Main dirt removal | Shampoo, two buckets. | Depends on the weather. |
| Claying | Removal of interspersions | Clay, lubricant | Not required |
| slug-out | Fat removal | Isopropyl alcohol | 2-3 minutes |
| Suit | Moisture removal | Air, napkins. | Complete drying |
Application technology: step-by-step algorithm
When the body is perfectly clean and fat-free, the most crucial moment begins - the application of the main layer.
You need to work in small areas, about 50 by 50 centimeters, to control the process of drying out the composition.
Apply the liquid to the applicator rather than directly to the body to avoid puddle formation and uneven distribution.
Movements must be cross-sectional: first vertical, then horizontal, to cover the entire area without passes.
It is important to monitor the exposure time specified in the instructions for a particular product.
Usually it is 1-2 minutes, after which the composition changes color or becomes matte, signaling readiness for polishing.
The main rule of application: it is better to apply two thin layers than one thick one. The thick layer will dry for a long time and it will be extremely difficult to polish it qualitatively, leaving divorces.
Polishing is done with a clean dry napkin, constantly turning it over to work with the dry side.
If the wipe becomes wet or heavy, replace it with a new one, otherwise you will simply smear the remnants of the chemistry on the surface.
After processing all the elements, allow the car to stand in a warm room for a minimum of 12 hours for primary polymerization.
Common Mistakes and How to Avoid Them
Even with the technology, beginners often make mistakes that affect the appearance and durability of the coating.
One of the most common problems is applying the composition to a hot body or under direct sun.
Under such conditions, the solvent evaporates instantly, and the ceramics crystallize before time, imaging indissoluble spots (chola).
⚠️ Warning: If you notice that the composition began to dry faster than expected, stop immediately. Don’t try to rub it harder, it will only make things worse. It is better to carefully remove the excess and apply the layer again.
Another mistake is not enough wipes for polishing.
Many save on consumables, using the same rag to the last, which leads to the appearance of micro scratches and smearing dirt.
Also often forget about the pasting of plastic elements, rubber bands and glass, where ceramics fall by chance.
Plastic-frozen ceramics can change its color or create a whitish coating that is very difficult to remove without aggressive solvents.
- 🚫 Ignoring instructions Each brand has its own nuances in terms of drying time and temperature.
- 💨 Draw and dust - Working in an open garage can lead to the settling of dust on a sticky layer.
- 🧴 Poor-quality wipes - Pile from cheap fabrics can stick to the ceramics dead.
Ceramics care and extension of service life
After you have spent so much time and effort, you want the result to be as happy as possible.
Ceramics are not armor, but a hydrophobic coating that also requires careful treatment and proper care.
The first 7-14 days after application, it is recommended not to wet the car and not to use chemical sinks, as the process of final polymerization is underway.
In the future, wash the car in a non-contact way, using shampoos with a neutral pH, which do not contain aggressive alkalis and acids.
Brushes and sponges on automatic washings can leave a small risk on the surface, which will be noticeable in the sun, despite the presence of protection.
Every 2-3 months you can use a special activator or spray care for ceramics, which refreshes the hydrophobic effect.
⚠️ Warning: Avoid using "folk washing products" such as Fairy or other dishwashing products. They contain aggressive surfactants that quickly destroy the ceramic layer.
The myth of self-healing
Ceramics do not have the self-healing effect of scratches, like some polyurethane films. Small risks can be visually hidden by filling the pores and optical properties of the composition, but the material is not physically restored.
Regular surface inspection will allow you to notice the areas where the hydrophobe has weakened in time and carry out local updating.
Proper care can extend the life of the coating to the manufacturer's stated term and even more.
Can I apply ceramics to an old car with scuffs?
Yes, you can, but ceramics will not hide defects, but only preserve them. Moreover, on a dark background, scratches will become even more noticeable. It is recommended to carry out a light reductive polishing before applying.
How many layers of ceramics are really needed?
For most of the compositions, one quality layer is enough. The second layer makes sense to apply only after a day to increase the depth of color, but more than three layers apply pointlessly – the coating will not become thicker, but will simply start to crack.
What is dangerous about an overdose of the composition?
A layer that is too thick will not have time to polymerize evenly. The inner part will remain liquid, and the outer will harden, which will lead to the appearance of iridescent divorces, which cannot be removed by polishing without removing the entire layer.
Do I need to polish the car after applying ceramics?
No, finishing polishing with abrasive pastes after applying ceramics is prohibited, as you will simply wipe the protective layer. Pollination is performed only before application, at the preparation stage.
How long does the pottery dry?
Primary drying (when you can touch) takes 1-2 hours. Full polymerization and hardness set occur within 7-14 days, depending on humidity and air temperature.
