Liquid glass for car: what it is, which one to choose, preparation and coating technique

The car should be happy for the owner, but over time or due to some negligence, the protective layer will weaken, the car will rust, stains, scratches, cracks will appear. The protective layer needs our constant support. And in this the best assistant is the liquid glass (ZhS) for cars.

In order to understand its importance, in order for a car to be in excellent condition for a long time, you must first learn the components, capabilities, and proper use of the ZhS that you choose from the market.

What is liquid glass for a car

Advances in technology have made it possible to move from wax to silicon protective polishing. Of course, this is not pure silicon, but complex compositions based on it. During a lightning strike on the sand, glass is formed - silicates, silicon salts. The basis of the high-temperature natural phenomenon is the manufacturing technology of infinite variations of solid glass. But glass can also be liquid if you remove the calcium component during its manufacture. Liquid glass is used to manufacture and create many materials in many industries. Most often silicone-based ZhS - in sodium or potassium alkaline solutions.

Since 2008, SiO2has also been included in the automotive ZhS silicone base. To this is added a special technology:

    titanium and aluminum oxides;
  • surfactants (surfactants);
  • components for the production of polymer films.

Each additive imparts certain properties to ZhS. Titanium oxide (along with the polymer components) forms a heat shielding film. The film of nanoparticles gives light to the body and allows the qualification of ZhS nanoceramics.

Surfactants are responsible for cleanliness - they remove any remaining contaminants from the body's already cleaned surface.

The silicone component prevents oxidation of the body and ensures better adhesion of ZhS to the body surface as well as protection of the latter.

The use of silica significantly increases the durability of the paintwork.

How to make liquid glass

ZhS Manufacturing Technologies:

  • Soda with soda with sand:natural sand and technical soda are mixed, the mixture is specially incinerated. oven (1300 ° C), cooled. The resulting glassy lumps are dissolved with high pressure steam (or crushed to a powder which is then dissolved in hot water).
  • Processing of silicon raw materials: after grinding the raw materials, alkali (mainly sodium) is added, the mixture is placed in a autoclave with a vibrator and at a temperature of 1000 ° C.
  • Hydrothermal technology: Silicon raw materials are dissolved in concentrated alkaline solutions by releasing large amounts of heat, so no additional heating is required.
  • New technology(simple and cheap): silicate is used as a raw material for silicon, which is washed, cleaned of metal oxides, crushed, melted, and turned into silicate monolith. Then boil water in a vibrating mixer.

What features of the ZhS allow you to protect your car body

The formed thermal protection film not only covers the factory paint layer, the film and the paint atoms diffuse. This allows you to:

liquid glass for body coating
  • prevents oxygen from entering the paint layer;
  • prevents corrosive substances from entering the body;
  • repels contaminants, do not leave streaks after rain;
  • Protect the paint layer from direct sunlight while maintaining color depth.

The presence of SiO2in ZhS strengthens the body's factory lacquer coating and prevents minor surface damage. This is facilitated not only by the strength properties of the dioxide, but also by a certain plasticity of the liquid mixture.

What happens to ZhS

After applying ZhS, the following is available:

  • Reduces the need to wash vehicles frequently. It is often enough to wipe off dirt with a damp sponge or cloth.
  • The toner is protected from fading and fading. The factory color restores depth and saturation.
  • The original layer is protected from cracks and loss of appearance.
  • The car is protected from rust because the liquid glass foil insulates the metal surface of the body.

Important:Existing minor superficial lesions are filled with JS and become invisible.

Liquid glass features

The properties of liquid glass are as follows:

  1. Preservation of lacquer-paint coating - diffusion of ZhS and lacquer due to film formationThe sun's ultraviolet does not spread, the increased temperature is not terrible.
  2. Restore the original color. Filling micro-cracks, small bruises and scratches, and increasing the thickness of the paint and varnish layer, which increases depth and saturation.
  3. Body corrosion protection. It does not allow water, dirt, salt, sand and other aggressive substances to enter the metal body.
  4. Water and dirt repellent.
  5. Gives shine, luxury to the look of the car.
  6. liquid glass functions for car
  7. Increased durability - compared to other polishers.
  8. Antistatic. Prevents electrification of the body surface.

The car has a hydrophobic effect (repels water and dirt) and can be washed much less often. And the residue can be removed with a damp cloth and the car will shine again. For cars, thanks to the ZhS, the stains are virtually invisible on the body.

What does liquid glass add to paint when you paint your car

The body surface is protected from aggressive substances, sun, high temperature, water and dirt. Everything increases the duration of the polishing and varnish-paint layer. In addition, surface micro-damage and factory paint aging remain hidden. That is, the car's original appearance is restored.

ZhS performs all of the protective and restorative functions described above much better than varnish. The latter has virtually no protection against aggressive substances.

Without the severity of the climate and the condition of the roads, liquid glass would retain its properties for 3 years. Under bad conditions, the average period is less than a year. According to the manufacturers, ZhS must withstand at least 80 washes, ie one and a half years.

Surface preparation

First step. Washing and drying the car outside

If made on its own, it should be noted that neither foam rubber nor a rag is suitable - they hold small solid particles well, which are sure to cover the body with a mesh of the smallest scratches. Required - rubber hose and soft, long bristle brush.

Seal the entire machine and wait a few minutes for the dirt to soak. In a bucket, make a solution of a special car shampoo (just him! ) And dip a brush in it to clean all the dirt, constantly pouring from a hose.

preparing the bodywork for the application of liquid glass

Important:Be sure to wash with shampoo and not hot water. Otherwise, the slightest dirt remains in the pores and cracks, which absorb moisture and then penetrate under the paint. The result will be rust.

First, however, clean all outlets of doors, thresholds, front fenders to prevent water from entering the cavities and causing further corrosion.

And at the end of the wash - remove all drops of water from the squeezed clean suede so that tiny white spots do not appear in place due to the sun’s rays.

To complete the first stage - wipe the entire washed surface with a dry, soft cloth (napkin).

Second step. Degreasing

Anything not dissolved by water will disappear.

The entire surface of the dried body is degreased with a special pungent odor agent, so the room must have a good extractor or work in a respirator. Always wear rubber gloves. First, a solvent is used, and after a while, remove dirt with a soft, lint-free cloth.

Be careful - if the dirt is bituminous, you will need to use a special bitumen cleaner. Never use petrol, kerosene and the like - for varnishes and paints. Only possible on bare metal surfaces. Remove the old paint. In the end, the body is covered with a cleansing solution and everything is washed away.

Cover the car with liquid glass by hand

The coating of the ZhS car consists of several stages, including primary and mirror grinding.

Primary polishing

This section requires prepared rooms and certain skills. The room should have equipment and tools - as in the painting booths. And dust, moisture and sun-free, necessarily well lit.

Polishing is easy. In the absence of noticeable chips without cracks or scratches, simple polishing is carried out - with a microfiber cloth and polisher - by circular motions (10-20) rubbed into a limited part of the body. If you record a large area at once, the layer will have time to dry out a bit and there will be a problem with rubbing.

sand a car before applying liquid glass

Deep polishing. Deep scratches and chips are first sanded with fine sandpaper, rubber bars and water. In this case, the sandpaper is softened in warm water.

Next - polishing with an automotive polishing machine using polishing paste. Of course, the professional model is preferred.

You can buy a cheap model or make it from an electric drill or grinder with special adapters for fixing polishing pads. However, without proper skills, it is easy to damage the paint layer.

With the right skills at this stage, the light damage of the surface is eliminated, homogeneity is restored, a protective layer is applied.

Mirror Painting

This is the main stage of the work. JS is given in circular motions, layer by layer. Optimal - 10-12 layers, minimum - 4. At the end, walk with a clean napkin on the treated surface, remove the whitish coating.

Further drying is a long process (6-12 hours). To achieve complete crystallization.

Machine liquid glass coating characteristics

Remember to follow these rules:

  • The conditions for cleanliness of the room and protection from the sun and rain must be met. Even in ideal weather, it’s better not to take risks and work in a non-open space - any gust of wind and work will be ruined by rising dust;
  • temperature during operation: 15-40 ° С;
  • When degreasing, be sure to remove the old coating;
  • Do not use the polisher at full power - in small areas;
  • do not press hard on the typewriter to avoid causing the surface to heat up strongly;
  • is ​​the next car wash - after 1-2 weeks at the earliest, but can be rinsed once a week.

Advantages and disadvantages of liquid glass

  • has increased.


  • cheap ZhS provides weak protection against alkaline solutions;
  • is ​​weaker in film than in shavings and sandblasting;
  • low plastic properties - may crack in the event of a collision or severe frost;
  • needs proper care, especially when washing;
  • requires certain skills.

Car Owners' Views on Liquid Glass Handling

Car owners have the following opinion about the ZhS:

  • Everyone remembers the bright light, brightness and saturation of the color, the smoothness of the drops. A clear advantage over waxing.
  • Easier to clean, less sticky dirt. In summer it does not fade so much.
  • When ZhS is applied, it dries quickly, the treated area is slightly larger, and everything is ruined. Too bad that quality preparations are very expensive.
  • More reliable than standard paint and better, more durable looking.
