Direct application of antigravium on the glossy surface of the varnish without a preliminary wool will lead to detachment of the protective layer and the formation of bubbles under the pressure of the oncoming air flow. Many owners, trying to save time, ignore the need to create an adhesive layer, which is a critical mistake when working with aerosol compounds. Chemical composition Most cans do not allow them to reliably adhere to a smooth lacquer coating, as they are designed for rough soil or metal.

Attempts to protect the rapids or arches in this way often result in the fact that after a few months of operation, the protective film begins to chip together with pieces of factory paint. Moisture penetrating under the detached material triggers irreversible corrosion processes, which are much more expensive to eliminate than initially conducting high-quality preparation. That is why the question of compatibility of components and application technology requires a detailed analysis to avoid expensive repairs. bodywork in the future.

Chemical compatibility of paint coating and antigravityh2>

The basis of the problem is often a conflict of chemical components that are part of the aerosol spray and factory varnish of the car. SolventsThe varnishes contained in liquid antigravity can aggressively affect some types of varnishes, causing them to soften or cloud before the moment of polymerization of the protective layer. This is especially true for soft-varnished cars, which are often found in Japanese and Korean manufacturers.

⚠️ Warning: Before applying fully, be sure to conduct a compatibility test on an inconspicuous section of the body to exclude a solvent reaction with varnish.

On the other hand, if the composition is too inert, it simply won’t be able to penetrate the surface microstructure. Glossy lacquer has minimal porosity, which physically eliminates the possibility of mechanical engagement (cohesion) of heavy particles of antigravel mastic. The result is a β€œglass” effect, where two materials are simply pressed against each other but are not chemically or mechanically bonded.

To ensure the durability of the coating, special archetypal Or you can wrap the surface carefully. Without this step, even the most expensive can of a well-known brand does not guarantee protection. It is important to understand that anti-gravity spray often has a less aggressive formula than professional pistol compounds, which makes pre-preparation of the surface even more important.

Risks of damage to the LCP if applied incorrectly

Ignoring the technology of preparation carries serious risks to the appearance and integrity of the car. One of the main consequences is the bloating of the coating, which occurs due to trapped solvents (locked solvents). When a dense layer of antigravity is applied from above, the solvent has nowhere to evaporate, and it begins to tear the lacquer layer from the inside, forming characteristic β€œcraters”.

Another problem is uneven drying. On a smooth surface, the liquid composition can drain, forming floods, which after solidification turn into vulnerable zones. In (places) most often start chipping stones, as the elasticity of the layer is broken. The damaged area becomes a hotbed of corrosion, and the rust begins to spread under the protective layer, remaining unnoticed until the moment of serious destruction of the metal.

  • πŸ’§ The formation of condensate and rust under a layer of antigravity due to leakage.
  • 🎨 Chemical varnishing and changing the color of the coating at the points of contact.
  • πŸ“‰ Reduced residual value of the car when selling due to poor quality of the thresholds.

Necessary surface preparation before treatment

Quality preparation takes up to 80% of the time of all work and is a guarantee that anti-gravity will last for years. The first step is always a thorough washing and degreasing of the surface. Use special ones. degreaser silicone-based to remove bitumen, oils and wax that may interfere with adhesion.

Next comes the most important step – creating roughness. The glossy varnish must be wrapped. For this purpose, an abrasive material with a gradation of P240–P320 is used. No need to wash the varnish to metal, just remove the gloss and create a uniform risk throughout the treated area. This will create the necessary micro-relief to engage the soil.

After machining, degreasing is done again to remove the dust left over from grinding. If there are islands of gloss on the surface, antigravel in these places will not lie. Also, use is recommended. primer (soil) for plastic or metal, depending on what is under the varnish, if you plan to clean to metal in damaged areas.

Technology of application of antigravity from an aerosol balloon

The process of applying antigravity from a can of canister requires compliance with the temperature regime and spraying technique. The optimum ambient temperature should be from +15 to +25 degrees Celsius. At lower temperatures, the composition becomes too viscous and lies unevenly, and at high temperatures it dries too quickly, without having time to spread.

Before starting work, the canister must be shaken intensively for 2-3 minutes. Inside is a metal ball that helps mix the components. Apply the composition should be from a distance of 20-30 cm from the surface, holding the balloon perpendicular to the plane of treatment. Movements should be smooth, reciprocal.

πŸ’‘

Tip: Don’t try to cover the surface from the first layer. It is better to apply 2-3 thin layers with interlayer drying for 10-15 minutes than one thick one that leaks.

It is important to follow the sequence of layers. The first layer is made thin, almost transparent ("foggy") to provide primary adhesion. Subsequent layers are applied more saturatedly, forming the required thickness of the protective film. Between the layers, be sure to let the composition dry, otherwise the solvents can "boil" and spoil the coating structure.

Comparison of aerosol compositions and professional equipment

The choice between a canister and a professional gun often comes before the car owner. Aerosol options are convenient for local repairs or handling small areas such as door edges or small chips. However, their performance and spray torch quality are inferior to professional equipment.

The table below provides a comparison of key characteristics, which will help determine the choice of protection method:

Parameter Aerosol cylinder Professional pistol
Thickness of layer Smaller, more layers needed High, controlled by pressure
Material consumption Tall (part evaporates) Economical, controlled
Texture quality Depends on skill, often "orange" Uniform, controlled shaft
Cost of processing Low (material only) High (work + material)
Secrets of the professionals

To obtain a texture "like a factory" when working with a can, the last layer can be slightly dusted from a greater distance (40 cm) to smooth out the shaft.

Polymerization time and post-processing operation

Full polymerization of antigravel compositions is a long process. Although the surface film dries in 30-60 minutes ("dust"), the final strength and evaporation of all solvents takes between 24 and 48 hours. During this period, it is better not to operate the car, especially in wet weather or on dusty roads.

On the first day after application, it is strictly not recommended to wash the car, especially with the use of chemistry or high pressure. Water can disrupt the film formation process, leaving whitish stains or matte spots. If the treatment was carried out on the thresholds, try not to go into deep puddles and dirt for the first two days.

⚠️ Caution: Complete crystallization and maximum elasticity are achieved only 7-10 days after application. Until then, the coating remains vulnerable to mechanical stress.

FAQ: Frequently Asked Questions

Can you apply antigravel directly to rust?

Absolutely not. Antigravity is not a rust converter. Applying it to corrosion conserves moisture and accelerates the destruction of the metal. Rust must be completely cleaned to metal, treated with a converter (if there are micro-focals), primed and only then applied protection.

Do I need to seal the neighboring parts with paint tape?

Yes, it's a requirement. Antigravel spray is very volatile. Getting on the glass, chrome elements or the main color of the body, it forms a crust that is difficult to wash. Carefully mask all the surrounding areas with paint tape and cover film.

How to remove antigravel if it is not well?

Fresh antigravity can be tried to remove with a paint solvent or a special washer. If the composition has already been polymerized (more than a day has passed), mechanical removal will be difficult. Often you have to carefully cut the layer with a scalpel and clean the surface again, which can damage the varnish.

How many cans do you need on one doorstep?

On average, 2–3 cylinders of 450–500 ml are used on one threshold of average length when applied in 3 layers. The consumption depends on the manufacturer of the composition and the desired thickness of the "shagrene" surface. It is better to buy with a stock so as not to interrupt the process.

πŸ’‘

The main conclusion: Antigravel paint can be applied, but only after careful matting and degreasing. Direct application on the gloss guarantees the detachment of the coating in the near future.
