A black glossy car always attracts attention, but this color is considered the most difficult to care for and paint. Any scratch, dust or “spiderweb” on this background becomes visible to the naked eye, turning a luxurious view into a matte spot. Choosing the right one squirrel This is only half of the success, the second half lies in impeccable surface preparation and compliance with application technology.
Many motorists mistakenly believe that it is enough to buy a can in the nearest store and spray it on the body. In fact, professional coating requires the use of two-component systems, where the base is mixed with a hardener, and a layer is necessarily applied on top. varnish. It is the varnish that is responsible for the depth of color and the very “mirror” effect that is valued in black cars.
In this article, we will analyze all the nuances of working with black: from the choice between acrylic and metallic to polishing the finished coating. You will learn why saving on materials is unacceptable here, and what tools are really necessary to obtain factory quality. The depth of black color directly depends on the quality of preparation and drying conditions.
Selection of coating type: acrylic, metallic or nitro?
The first thing to decide before buying materials is the chemical basis of enamel. To obtain a persistent black gloss, three main options are most often considered, each of which has its own characteristics of operation. Acrylic enamel (2K) are the gold standard for garage paint, as they form a strong film that is resistant to ultraviolet and chemistry.
In contrast, nitroemal (1K) dries solely by evaporating the solvent. They give a good initial shine, but over time they can lose color saturation and require a lacquer layer to be applied for durability. If you want to get the effect of depth, you should pay attention to black. metallic, containing aluminum powder.
Modern materials often include special additives that increase the elasticity of the coating. This is critical for plastic body elements that are subject to temperature deformations. When choosing paint, carefully study the manufacturer's technical maps.
- 🎨 Acrylic two-component enamel: requires mixing with a hardener, creates a very hard and chemically resistant coating, ideal for body elements.
- 💎 Black metallic: contains aluminum particles, gives a transfused effect, but requires a mandatory coating with varnish for the manifestation of depth.
- 💧 Nitroemal (1K): One-component, drys quickly but is less durable, often used for local repairs or painting discs.
- 🛡️ Polyurethane formulations: Professional level of protection, high price, used in premium deckling and restoration.
⚠️ Attention: Never mix paints of different chemical bases (for example, acrylic with nitro). This will lead to an immediate reaction, the material folding and the inability to use it further.
It is also worth mentioning the existence of special restoration kits that include all the necessary components. However, for a complete repainting of the body, it is better to purchase materials for bottling, checking the release date. Fresh paint lies smoother and is better polymerized.
Necessary tools and surface preparation
The quality of the final result depends on the preparation by 80%. Even the most expensive squirrel It will not hide irregularities, risks from sandpaper or residues of fat. The process begins with thorough washing and degreasing of the surface with special anti-silicone compounds.
To work, you will need not only a spray gun, but also a whole arsenal of auxiliary equipment. A grinder with different moves of the eccentric will remove the old coating and form the correct risk profile. It is important to use gradations of abrasives consistently without jumping over numbers.
Pay special attention to the repair area. The boundaries of the transition of the old lacquer to the new should be carefully wrapped. If you work in a garage, it is critical to take care of the absence of dust. Use sticky wipes immediately before applying each layer.
☑️ Checklist for preparation for painting
The room temperature must meet the requirements of the materials manufacturer, usually a range of +18 to +22 °C. The cold metal of the body can lead to condensation, which manifests itself in the form of craters or matte spots on a glossy black background.
Application technology: base and varnish
The process of painting a black car requires special discipline. Usually the scheme "base + varnish" is used. The base layer is responsible for color and cover, and the varnish is responsible for protection and shine. They must be applied in compliance with the interlayer shutter speed specified in the technical map.
The first layer of the base is applied with a thin, “swimmering” layer. This is necessary to create adhesion and prevent subtremities. Do not try to paint the surface “deaf”. Let solvent evaporate within 10-15 minutes.
The second and third layers of the base are applied more fatty, covering the surface with wet moctomy. It is important to monitor the uniformity of the spray. Black color is merciless to the "apples" and stripes. After drying the base (it will become matte), you can move to varnishing.
The parameters of the spray gun setting for the base:Duse: 1.3 - 1.4 mm
Pressure: 2.0 - 2.5 atm
Torch: medium or wide
Distance to the surface: 20-25 cm
The lacquer is applied in two layers. The first is thin, to tie the base. The second is the main, glossy, which forms the "body" of the coating. It is important not to overdry the first layer of lacquer, otherwise interlayer adhesion may be broken, and the lacquer will eventually begin to peel off.
Use a “control strip” (test card) with the same risk profile as on the body to check the spray gun settings before starting work.
Table of popular shades and codes of black
Black doesn’t always mean just “black.” There are many shades, from warm, going to brown, to cold with a blue tint. In local repairs, getting into the shade is a critical task.
Below is a table with the most common black color codes from different manufacturers. Remember that over time, factory paint burns out, so computer selection with coloring is mandatory.
| Manufacturer | The name of the shade | Paint code. | Type |
|---|---|---|---|
| Toyota | Super Black | 202 | Acrylic/Bazazaz |
| BMW | Sapphire Black | 475 | Metallic |
| Mercedes-Benz | Obsidian Black | 197 | Metallic |
| VAG (Audi/VW) | Brilliant Black | LC9C | pearl |
| Ford | Tuxedo Black | UH | acrylic |
When ordering paint in the tingling station, always call the code indicated on the plate of the car body. It can be on the front of the driver's door, under the hood or in the trunk. Visually identifying color by eye often leads to errors.
Typical defects and ways to eliminate them
The black gloss reveals the slightest flaws of the painter. The most common problem is shashaven ("orange peel"). It occurs due to too viscous paint, improper pressure or violation of the temperature regime of drying.
Another enemy is dust and villi, settled on fresh varnish. Small defects can be eliminated by polishing, but large decays require a careful cut with a blade and repainting of the element. Craters ("fish eye") are often the result of silicone or oil getting into the paint.
- 🌫️ Shagrin: is eliminated by grinding the abrasive P1500-P2000 and subsequent polishing.
- 💧 Subtext: They are cut with a stationery knife after complete polymerization, then grinded to zero.
- 🕸️ Craters: They require cleaning to the base and repainting, as the reason is often due to poor preparation.
- 🌫️ Matness (white coating): It occurs at high humidity, is treated with polishing or, in the worst case, repainting.
⚠️ Attention: Do not start polishing the black varnish immediately after painting. The polish should gain hardness, usually taking 24 hours to several weeks depending on the type of hardener.
To eliminate shavern on a black body, use an orbital grinding machine with a soft circle. Hand grinding can create bumps that will look like waves on a black background. Be very careful on the edges and edges of the body.
Care for a black glossy body
Painting a car is half the battle, the main thing is to keep the result. Black paint heats up more than others, which accelerates the burnout and aging of the varnish. Regular washing and use of protective compounds are mandatory.
Use shampoos with a neutral pH and be sure to apply a two-phase wash (pre-application of active foam). Contact washing with a sponge is permissible only after the main dirt is knocked down by water, otherwise you are guaranteed to leave circular risks.
The secret of “liquid glass” for black cars
The application of ceramic compounds or liquid glass creates an additional hydrophobic layer. The dirt sticks less to the body, and the water rolls down with balls, carrying away the dust. For black gloss, this is the best way to extend the life of the varnish and maintain the depth of color.
Once every 3-4 months, it is recommended to apply wax or synthetic sealant. This will fill the micro-scratch and give extra shine. If you notice that the shine has disappeared and the mattness has appeared, then it is time for a restorative polishing.
The main enemy of black gloss is the wrong wash. Refuse automatic brush washers if you want to keep the body without a "web".
Frequently Asked Questions (FAQ)
How much dried black glossy paint before polishing?
The time of complete polymerization depends on the type of hardener. For standard systems (HS) at +20°C, this is about 24 hours. However, for deep polishing, it is better to wait 3-4 weeks so that the polish finally gained hardness and did not “fail” after polishing.
Can you paint a black car without removing the old varnish?
Yes, if the old coating does not have deep damage and detachment. It is enough to carefully wrap the surface with abrasive P800-P1000, degrease and apply new layers of base and varnish. This is called "place-by-place" painting.
Why do you see all the scratches on the black car?
Black absorbs light rather than reflecting it chaoticly like light tones. Any risk on the varnish changes the angle of reflection of light, creating a contrasting white line against a dark background. This is an optical effect characteristic of all dark glossy surfaces.
Which is the best color to choose for metallic metal?
For high-quality spraying of metallic and obtaining a level background spray gun system HVLP or LVMP with a duse of 1.3 mm. They provide a soft torch and minimize material loss, which is critical for expensive black pigments.
