The appearance of even a small damage to the paintwork on the body of the car always causes the owner of mixed feelings. On the one hand, it is an inevitable payment for active operation of the vehicle, and on the other hand, a potential hotbed of future corrosion, which can lead to expensive repairs. It is at such times that help comes. chip-paintIt allows to eliminate the defect and protect the metal from aggressive environmental influences.
Modern technologies of production of auto cosmetics have stepped far forward, turning the process of local repair from the lot of professional painters into an affordable procedure for any motorist. A competently selected set of tools allows you to achieve a result that is visually almost indistinguishable from the factory coating, if you follow all the technological nuances. In this article, we will discuss in detail what is included in the quality set, how to choose the right color and gradually perform the restoration of the damaged area.
Ignoring small scratches and chips is the way to big body problems. Moisture, reagents and temperature changes will quickly reach the metal, triggering irreversible oxidation processes. Use of specialized pencil-cloth Or a bottle with selected enamel is the fastest and most economical way to stop the destruction and maintain the presentation of the machine.
What is included in the standard set for the restoration of the LCP
Basic equipment sets can vary significantly depending on the manufacturer and price category of the product. Simple options may include only a bottle of enamel and a brush, while professional solutions offer a whole arsenal of tools to achieve perfect smoothness. Understanding the kit composition will help you choose exactly what is needed for a specific type of damage.
The main component is always the paint itself, matched to the color code of your car. It can be delivered in the form pencil-cloth, a vial with a brush or an aerosol cylinder. For more serious damage, where not only the color, but also the geometry of the surface is disturbed, a polyester varnish or acrylic composition is included in the kit to create a protective layer.
- 🎨 Enamel-based - pigmented composition, exactly corresponding to the factory shade of the body.
- 💧 Solvent or degreasing - necessary for surface preparation and cleaning of tools.
- 🛡️ Lacquer layer - transparent coating, providing gloss and protection from ultraviolet light.
- 🧽 Abrasive materials - polishing wipes or mini-slimes for finishing.
It is important to note that the availability degreaser The kit is critical. Without careful surface preparation, even the best quality paint will not be able to adhese with the metal and will soon begin to peel off. Some advanced kits also include a rust neutralizer that converts the oxides into a stable compound before painting.
⚠️ Note: Not all sets are universal. If you have a car with a metallic or mother of pearl effect, make sure that there is a separate bottle of varnish in the kit. Without a lacquer layer, such colors look dull and do not have a characteristic shine.
How to choose the right color of paint for the car
The most difficult stage in the restoration process is to find the exact match of the shade. Even the same paint code at different plants or in different years of production can have differences. In addition, the paint on the car burns out over time under the influence of the sun, so the new enamel can look brighter than the old coating.
First, you need to find colour your car. It is usually located on a special plate that is attached to the door opening, under the hood or in the trunk. The desired combination of letters and numbers is often referred to as "Color", "Paint", or "Farbe". It is on this code that the main pigment is selected.
What to do if the color code is not readable?
If the plate is damaged or rubbed, the color code can be found in the car service book, on checks from previous body repairs or check with the official dealer by VIN number. There are also online databases where you can determine the factory hue by VIN.
When buying a set, pay attention to the date of production of the paint. Old enamel may have a dissection of components or a changed consistency, which will make it impossible to obtain a qualitative result. Fresh. repair-stock It provides better cover and adhesion.
In cases where an exact match cannot be found, experienced masters use the method of "stuffing". They apply paint not only to the center of the chip, but also slightly go to the edges, and then polish the transition, making it invisible to the eye. It takes skill, but it allows you to hide the difference.
Preparation of the surface before applying enamel
The quality of surface preparation determines 80% of the success of the entire operation. Applying paint on a dirty, greasy or rusty surface is a waste of time and materials. The metal must be absolutely clean and dry to ensure maximum adhesion of the layers.
The damaged area must be thoroughly washed and dried first. All loose particles of paint and rust should be removed. For this, you can use a thin scalpel sting, toothpick or special sandpaper with grain P1000-P1500. The main thing is not to damage the healthy coating around the chip.
☑️ Checklist for preparation for painting
After mechanical cleaning is necessarily used degreaser. Wipe the repair site with a napkin dipped in the composition, and wait for its complete evaporation. Do not touch the prepared surface with your fingers, as the skin fat will also worsen adhesion.
If the chip is deep and metal is visible in it, it is recommended to pre-process it. ground Or a rust converter. The soil creates an intermediate layer that improves the adhesion of the paint to the metal and prevents further spread of corrosion under the coating.
Technology of applying paint and varnish step by step
The process of applying paint requires patience and accuracy. Do not try to paint the chip in one layer - this will lead to the formation of flows and bumps. It is better to apply several thin layers, allowing each to dry according to the instructions on the bottle.
If you use pencil-breakerJust press your nose to the center of the damage and wait for the paint to appear. If the work is carried out with a brush, type the minimum amount of enamel and carefully fill the chip cavity. Movements should be point-based, without smearing at the edges.
| Phase | Action. | Drying time | Tool. |
|---|---|---|---|
| 1 | Applying soil (if necessary) | 15.30 minutes. | Brush/applicator |
| 2 | First layer of enamel | 20-40 minutes. | Brush/pencil |
| 3 | Second layer of enamel | 1-2 hours | Brush/pencil |
| 4 | Lacquer application | 24 hours. | Brush/applicator |
After drying the base color (usually after 1-2 hours), you can start applying the varnish. The varnish is applied similarly to paint - in thin layers. It should completely cover the enamel and slightly protrude above the level of the main coating, since after polishing the volume will decrease.
Apply varnish with a small margin in height, forming a micro-lens. After full polymerization, you level this bump with polishing, giving a perfectly flat surface.
⚠️ Warning: Do not try to accelerate drying with a hair dryer or heating. A sharp temperature drop can lead to clouding of the varnish (the effect of “bleach”) or cracking of the fresh coating.
Finishing polishing and elimination of transitions
Once all the layers have dried (it is better to wait 24 hours for full polymerization), the repair site will look like a bump. It's normal. The next step is to level the surface and remove the transitions between the old and new paint.
Abrasive polishing is used first. You will need a polishing machine or drill with a nozzle, as well as abrasive pastes of different grains. Start with a rougher paste (P1500-P2000), carefully removing excess varnish and paint until the surface is smooth to the touch.
Then move on to the finish polish with a softer paste, which removes the matte and returns a deep gloss. Movements should be smooth, without strong pressure, so as not to wipe the coating to metal. As a result, the transition line becomes invisible.
- 🌀 Abrasive paste - for the primary removal of the layer and alignment.
- ✨ Finish pasta To restore the brilliance and depth of color.
- 🧶 Polishing circles Hard for the first stage, soft for the finish.
If you do not have experience with a polishing machine, you can use a manual method using special polishing wipes, which sometimes come in the form of a stainless machine. chip-pin. This is longer but safer for the beginner, as it eliminates the risk of overheating and rubbing the coating.
Common mistakes in self-repair
Even with a quality tool at hand, it is easy to make a mistake that will ruin the result. One of the most common problems is applying paint to a wet or cold surface. The condensate left in the micropores will later bulge into the coating.
Another common mistake is using the wrong solvents. Aggressive chemistry can eat away at the edges of old lacquer, creating craters or clouding around the repair area. Always check the compatibility of the materials.
The secret to success is multi-layeredness. Better 5 thin layers that dry evenly than one thick layer that will flow and dry for weeks.
Also, do not ignore the temperature regime. The optimal temperature for work is from +15 to +25 degrees Celsius. In the cold, the paint thickens and falls poorly, and in the extreme heat it dries too quickly, without having time to spread.
Can I use regular spray paint?
Using regular enamel from the construction store is not recommended. Automotive paints have a complex chemical composition, resistant to gasoline, oil and ultraviet. Ordinary paint will quickly fade, crack and will not stay on the body.
How much does the chipping kit dry?
The drying time depends on temperature and humidity. Surface drying takes 20-40 minutes, but complete polymerization and strength gain occur within 24 hours. The polish can dry up to 48 hours before polishing.
Do I need to seal the area around the chip?
Yes, if you are working with a brush or aerosol, be sure to paste paint tape around the damage. This will protect the clean paint coating from accidental splashes and facilitate the finish polishing of the transitions.
What to do if the color is different?
If the difference in hue is noticeable, you can try mixing the contents of two adjacent paint codes (if they are available) or using the method of polishing the transitions to make the border less noticeable. Sometimes it helps to tint the varnish.
