Many cars have a special plastic lining inside the car. The panel comes straight from the factory in the usual black color. For black or dark-colored cars this is not a big problem, but if your car is silver or white, then the black panel stands out significantly. Therefore, companies such as LRS offer services such as full or partial painting of the car http://lrsauto.ru/pokraska and various car parts.
In addition, time also affects the plastic of the interior; scratches, worn places appear, and sometimes cracks and small dents appear. Polishes cannot help restore original appearance plastic panel. Therefore, painting will be optimal solution. But, many questions arise regarding how to paint plastic in a car interior, and whether it is possible to do it yourself. In this case, the main task is safety and proper adherence to painting technology.
How to paint plastic in a car interior?
Specialized stores and market stalls offer a fairly wide selection of paint manufacturers for interior cutting of cars. The choice of how to paint the plastic in the car interior should be made from two paint options, namely:
- acrylic;
- aerosol.
Please note that the use of durable acrylic necessarily involves the additional purchase of a plasticizer.
Speaking about the regular aerosol version of paint, it is the easiest to use and costs less acrylic analogues. Another advantage is that this paint dries faster. But, it has poor connecting properties (adhesion) with the painted surface. The master has to spend more time preparing the parts and it is not always possible to choose a color that will hide the defects that have formed on the plastic.
Both cylinders and cans can contain grainy or structural paint, which is ideal for painting parts after repair and restoration, restoration work. This option allows you to fully restore the appearance of the product and its structural features. The surface is slightly voluminous, with a slight pimply roughness.
Once the product has been structurally coated, it will be more susceptible to mechanical impact, not susceptible to medium heat and water. We also note that such a substance dries quickly and reduces work time. Does not require subsequent application of varnish. Good producers Structural paint companies are APP, Novol, Body, R-M.
The primer can be purchased separately. Plastic in different cars has different degrees of quality, therefore, for the safety and protection of the panel, you should purchase paint material and primer from the same manufacturer. This will ensure good adhesion between the coating layers.
DIY car interior painting
The plastic material can be painted in any desired monotone or bright color, matching the shade of the car. You can also use different colors to make the panel not only refresh its appearance, but also stand out even more. By purchasing some paint and materials for the job at a specialized auto parts store, your plastic trim the interior will be painted in just a few hours.
If you decide to paint the plastic inside your car with a spray can, you need to prepare and purchase some products from the list, since working with car parts is more difficult than painting a car sheet metal. Plastic auto parts include decorative details, door handles, mirror housing and other elements.
But let us remember that the application spray paint For plastic this is not a good idea as the paint will crack, peel and peel within a short period of time.
Do-it-yourself painting of car interior plastic requires the following accessories:
- To remove parts you will need a screwdriver, tweezers, forks, pliers, etc. (when removing, do not damage the fastenings of the elements);
- If the plastic cannot be removed, then prepare protective film, paper, cardboard and tape for covering non-paintable surfaces;
- Paint, primer, plasticizer (if necessary);
- White spirit for degreasing, special wax or anti-grease;
- Antistatic from dust;
- Scratch putty;
- Spray gun, for can paint;
- Sandpaper with a grit level of 400;
- Urethane varnish;
- Brushes, if you are working without a spray gun and a can;
- Painting tape.
Your independent actions can be structured as follows:
- 1. Plastic panels cleaned manually using sandpaper. It is necessary to rub until they are smooth and pale gray. Then wipe the panels with wax or anti-grease to remove dust and fingerprints.
- 2. Secure duct tape and paper around the edges of the area you are painting. Wipe this area again with wax or a special anti-grease to remove fingerprints from your fingers, which can later cause bubbles under the paint.
- 3. Apply a thin layer of adhesion to the body of the product and let it dry for 30 minutes. This penetrates the surface of the plastic and provides surface support. Without adhesion, primer and paint will flake and peel over time.
- 4. Apply a thick coat of primer (if using alone) to the area and allow it to dry for 30 minutes. Lightly rub the surface with sandpaper until it is smooth. Wipe the panel with wax again.
- 5. Apply paint to the area starting from the edge, starting with two thin coats. Again we wait 30 minutes. Then pass over the dry paint with clear varnish, if necessary. We wait 15 minutes between each stage.
- 6. Then remove the masking tape and paper. Allow the panel to dry for 24 hours.

How to paint plastic at home?
Step-by-step instructions for painting plastic
Step_1 Clean the plastic surface from dirt using a sponge (brush) and soapy water. If dust and dirt remain on the product, the paint will not apply evenly and the product will have to be repainted. Heavy soiling, mold and erosion can be cleaned with bleach. Before starting work, dry the plastic product thoroughly.
|
Step_2 To degrease the surface, wipe it with solvent or white spirit, then rinse off the applied composition and dry the product thoroughly. Step_3 To create a porous structure, sand the surface with fine sandpaper or special grinder. Sanding will allow the paint to lie perfectly flat, due to the bonding of the paint and the porosity of the surface. After sanding, the surface will become matte. Correctly selected sandpaper will not give the product unwanted roughness, so it is better to choose sandpaper with a grit of no more than 180. Be sure to remove dust from sanding. |
 |
Step_4 Before painting the plastic at home, cover the areas that are not to be painted with construction tape and remove it immediately after finishing the work.
Step_5 Now you can start painting the plastic with spray paint. Shake the spray in the can for at least 30 seconds, spray the aerosol paint from a distance of 20-30 cm from the surface. You need to apply the paint with smooth, even movements. After the first layer has dried, which will take 15-20 minutes, apply subsequent layers of paint. When painting plastic, it is recommended to apply at least 2 - 3 layers of paint.
Step_6 After the spray paint has dried, apply the varnish in the same way and wait for it to dry. Complete (final) drying takes no less than 2 - 2.5 hours. The product is ready to use!
What to pay attention to when painting plastic?
As we have already said, plastic comes in different types, so it is recommended to carefully choose paint. Ideally, you need to use special paint for plastic.
5 In addition, please note that for aerosol paints in cans there are special tips for convenient regulation of the amount of paint sprayed and its uniform distribution
We talked about the simplest and effective way painting plastic at home using aerosol paints, however this procedure You can also apply it with a regular brush using canned paint.
How to paint plastic at home with a brush?
Painting plastic objects with a brush is somewhat different from the method described above and has its own advantages and disadvantages. One of the features is considered long term drying, which means that the product must be completely isolated from dust on the newly painted surface, which is not so easy at home. This is why the brush painting method is used to paint items that do not require much attention. The technology for painting plastic with a brush at home is quite simple and essentially repeats the process of working with aerosol paint:
Step_5 This is extra step. If you want to further protect the painted surface, you can apply acrylic varnish. Apply varnish ONLY to completely dry paint. In the case of aerosols, we know that the paint dries in 15-20 minutes, but here everything will depend on what kind of paint you use. Varnish drying time 2 - 2.5 hours
What should you pay attention to when applying paint to plastic with a brush?
1 Apply paint in a thin layer, constantly pressing the brush to the surface
2 When taking paint onto a brush, do not immerse the brush completely in the paint.
3 Take into account the painting angle - it should be the same.
4 For even coverage, apply the paint in wide stripes so that the paint fills the pores, and then carefully blend the applied layer.
So, we talked in detail about how and with what to paint plastic at home. You can safely start painting and make sure from experience that it is not at all difficult, and the result is worth the time and effort!

Painting plastic products is not an easy task, because smooth surface causes paint to run off. But it’s actually not difficult to deal with if you properly prepare the area to be treated and use the appropriate application method. decorative covering. We’ll tell you how to paint plastic in this article.
General rules for coloring plastic
First of all, it’s worth finding out which plastic surfaces can be painted and which cannot. Plastic material can be different types depending on the raw materials used in the manufacturing process. Each of them has certain characteristics, which is due to the unique properties of polymers.
If you need to paint plastic based on polypropylene or polyethylene (PE), then you should not waste your time. Coloring composition will flow over the surface without changing color. For example, metal-plastic ones are made from such raw materials. When purchasing them, you need to immediately select the appropriate tonality.
Various parts made of plastic are suitable for painting. Such surfaces are divided into two types:
Read also: Lining the base with artificial stone
Those in need preliminary preparation(PVC, ABS);
Requiring no treatment before applying paint.
Determine the need preparatory work you can do it yourself. To do this, use one of the following methods:
A plastic part is lowered into a container with water; if it does not sink to the bottom, a primer is needed; when drowning, no pre-treatment is carried out;
If there is such a possibility, then a piece of plastic needs to be set on fire; the presence of soot and black smoke indicates that the material is ready for painting, and if a clean and even flame is detected on a burning fragment, a primer must be applied to the surface.
Materials and tools
To perform painting works you need to prepare everything you need:
Primer composition;
Colored coating;
Fine sandpaper;
Masking tape;
Spray.
Coloring stages
When painting a plastic surface, the following sequence is observed:
Work surface clears away the old protective coating, if available heavy pollution, then it should be washed soap solution;
After drying, clean the plastic part with fine sandpaper, removing small scratches and other flaws;
Read also: Mosaic plaster (photo): advantages, application, application features
To improve surface adhesion, you need to remove dust with a dry rag and degrease alcohol solution(acetone solvent is also suitable);
It is recommended to cover those areas that cannot be painted. masking tape;
Apply the primer to the plastic using a brush (the composition is selected based on acrylic);
After drying, apply paint to the surface using a brush or spray.
Drying is carried out naturally or by force (using a hair dryer). Drying temperature is 18-60 degrees with a humidity level of up to 80%. Polymerization of the applied layer will be completed after a week, so it is not recommended to use the painted part for its intended purpose before this period.
As a primer, you can use primer for plastic, which is sold in car dealerships.
When preparing the surface, you need to thoroughly clean it from dirt and dust. It is equally important to remove oily stains. This can be done using a solvent.
There is no need to apply a primer layer if you plan to use acrylic-based paints for painting.
Painting plastic is a process that can be useful in many cases: from painting parts indoors to tuning your car. If you want to decorate your home, create in it stylish interior, without being too big material costs, the most in a simple way The way to give plastic objects and surfaces a second life is to paint them with beautiful and high-quality spray paint. The article will tell you what and how to paint plastic.
In everyday life plastic materials are called:
- Plastic.
- Polypropylene.
- Polycarbonate.
- Polystyrene.
Plastic, like any material, deteriorates over time, so the question is how to paint plastic, give it aesthetic appearance- always relevant.
Tip: The plastic to be painted should be thoroughly washed and dried before applying the coating. Special attention It is necessary to pay attention to the edges of objects that may become deformed or rubbed due to intensive use.
Before painting plastic, you need to become familiar with some of the nuances of performing the work:
- Surfaces must be cleaned of grease, oil and bitumen stains, and other contaminants using a solvent.
- The parts are treated with an antistatic agent - a liquid that relieves static stress that has accumulated during friction of the plastic. This is necessary to eliminate the possibility of attracting dust and small fluff to the surface when painting, which can harm the process.
- When processing old items, in order to correct any defects, a plastic putty is first applied, which differs from ordinary polyester putty because it is more elastic.
- All irregularities are rubbed down with abrasive, moisture-resistant sandpaper. In this case, mashing is carried out using water. This will eliminate all cracks and cracks.
- The part is thoroughly dried and degreased again.
- Surfaces are primed in approximately three thin layers to prevent drips. The primer provides better adhesion. The material can be used two-component or one-component, with different colors.
- After the primer layers have dried, the surface is matted for paint using abrasive sandpaper, number 400-500.
- Do-it-yourself painting with acrylic paint is done with the addition of plasticizer. The paint is applied from two to three layers with a spray gun. In this case, each layer must dry thoroughly before applying the next one.
- After 20-30 minutes, a layer of varnish is applied, if using metallic paint.
- A wax polishing paste is applied to remove minor defects that arose when painting the plastic.
Preparation of paints and other materials for painting
The produced range of paints allows you to choose any color, as in the photo, suitable for painting a plastic part.
How to paint plastic:
- For painting soft plastic products, it is better to use elastic enamels with a high content of plasticizers.
- Universal acrylic enamels are used for hard plastics.
- To improve adhesion, plastic surfaces are pre-primed.
Tip: Parts made of polystyrene, polycarbonate, and polyethylene cannot be painted.
For painting surfaces the following can be used:
- Paint for plastic in cans. It is easy to apply, and does not require special work skills; it is enough to strictly follow step by step instructions, which is applied to the material. Special tips are available for aerosol paints, which allow you to conveniently regulate the amount of spray composition and the uniformity of its distribution.
- An ordinary brush when painting a surface from a can. At the same time, the process becomes significantly more complicated due to the need for maximum isolation of the part from the presence of all kinds of dusty elements and fluff in the air, which is quite difficult to do.
Painting with a brush is indispensable if you need to make a high-quality coating on fairly small parts. In this case, the spray can will not cope.
Tip: The best effect when applying paint is obtained by immersing the brush in paintwork one third of its length and fast work, without waiting for the paint to start drying on the brush. During painting, the angle of inclination of the tool should be the same, and excess paint coating do push-ups on the edges of a container with paint.
Dipping a brush into a paint can
- Liquid plastic paint can be used on any type of surface. The coating creates a dense polymer layer that reliably protects the product from external influence and gives it the desired decorative effect. These are, most often, one-component compositions made on the basis of organic solvents, which contain fillers from polyurethane, alkyd or acrylic resins with the necessary plasticizers, pigments to impart color, and complex additives.
To paint plastic you will need:
- Sufficient quantity of plastic or aerosol paint acrylic enamel, its price is slightly higher.
- Acrylic aerosol varnish, matte or glossy - for final finishing details.
- Protective mask or goggles, gloves.
- Newspapers or plastic wrap.
- Scotch tape or masking tape.
- A container of water, rags, detergent.
- White spirit or other solvent.
- Fine sandpaper.
- Putty and primer, if available deep scratches and chips on the product.
Plastic coloring technology
Step-by-step coating of plastic with spray paint:
- The plastic surface is cleaned from dirt with a sponge or brush with soapy water. If there is dust and dirt on the product, the paint will not apply evenly and the surface will have to be repainted. Heavy dirt, erosion and mold can be removed with bleach. After this, the part is dried well.
- The surfaces are degreased with a solvent or white spirit, then the applied composition is washed off and the product is thoroughly dried.
- To make the structure porous, the surface is sanded with fine sandpaper or with a special machine for grinding. This will allow the paint to lie perfectly flat, which ensures the paint adheres to the porous material. The surface will become matte after sanding.
Tip: With the right sandpaper, the product does not acquire unwanted roughness. Sandpaper should have a grit of no more than 180. Be sure to remove dust after sanding.
- Places that are not to be painted are covered with construction tape, and after the work is completed, the material is immediately removed.
- The plastic is painted with aerosol paint. To do this:
- shake the spray in the can for at least 30 seconds;
- aerosol paint is sprayed from a distance of approximately 30 centimeters from the surface;
- The paint should be applied to the surface using uniform, smooth movements. After the first layer has dried, after 20 minutes, the next layers of paint are applied. It is recommended to apply up to three layers of coating on plastic.
- After the spray paint has dried, the varnish is applied in the same way.
The video in this article shows more details about coating application.
How to paint plastic with a brush
Painting plastic products with a brush is slightly different from the previously described method. The process has its own characteristics. One of them is considered to be a long drying time, which requires completely insulating the painted surfaces from dust. This is not so easy to do at home. Therefore, this brush painting method is used only for painting objects that do not require special attention.
The technology of painting with a brush is quite simple and practically repeats the process of applying spray paint:
- The product is washed before painting. Drying.
- Surfaces are degreased, wiped and dried.
- The parts are sanded and a primer is applied.
- Covered with paint.
- An additionally painted surface can be protected by applying acrylic varnish to it, but only after the paint has dried.
Painting plastic products allows you to extend their service life and change the appearance of the room.
Most home craftsmen think that painting plastic parts DIY is a fairly simple task. However, not all types of this material are equally suitable for this. Of course, it is possible to paint these surfaces, and the material will lie on them quite evenly, but the service life of the coating will be short-lived.
Once dry, the paint will begin to peel, crack, and peel.
Below we will try to give advice on:
- what kind of plastic can be painted at home;
- how to do it correctly;
- how to paint plastic.
What you need to know about plastic
This product happens different types, and each of them has its own unique properties. Therefore, the coloring process is different for everyone, sometimes radically different. By the way, in your work you may encounter plastics that cannot be painted.
An example would be products made of polyethylene (PE) or polypropylene or polyethylene, from the surfaces of which the paint will peel off in layers. Therefore, it is almost impossible to paint metal-plastic pipes made from polyethylene. So it’s better to immediately select the desired shade.
Automotive plastics can be divided into two types:
- require ;
- not required.
Tip: before completely erasing the paint from the plastic, conduct an experiment with a solvent on small area surfaces.
Before painting, it is necessary to determine the type of material as follows:
- Lower small piece product or its entirety into water:
- if it goes under water, then there is no need to prime the part;
- if it remains on the surface, therefore, the material requires the application of a special primer mixture for plastic.
- The next option is to set fire to a piece of plastic part that has been cleared of dirt and paint:
- will burn with black smoke and soot, which means you can do without applying a primer;
- the flame is even and clean, therefore, it is necessary to prime its surface.
How to paint plastic
Below is suggested detailed instructions which will help you understand this process. Try to stick to it to get the final coverage you want.
Plastic painting consists of several stages:
- Degreasing surfaces with special compounds.
- Application of primer.
- Applying an acrylic-based primer.
- Sanding acrylic primer.
- Surface painting.
Features of coloring plastic products
- PVC or ABS plastics can be painted, but they must first be treated with a primer to increase adhesion (sticking). You can buy them in auto stores, where they are sold under the name “primer for plastic,” or in stores that sell paint and varnish materials, for example, Otex-type primers from the Tikkurila company. These compounds can be applied by wiping the surface or spraying it, after which you need to wait until they dry, usually 1-2 minutes.
- Make sure that the surfaces of the prepared surfaces are free of dirt and oil, and that they are dry..
Advice: you don’t have to lead additional training surfaces for painting, if work is carried out with ABS plastics or polystyrene, on which it will be applied acrylic paint on water based.
- It is desirable that the temperature of plastic products, paint and painting equipment be the same. Ideal conditions can be considered when the room temperature is from 18˚C and the humidity does not exceed 80%.
- Paint in one layer, the thickness of which should be about 60 microns. With a lower setting, the finishing coat may seem fragile and the paint will not be able to stay on the surface of the product for a long time. At the same time, with a thick layer (more than 120 microns), the drying time will increase, which often has a bad effect on appearance coverings.
- Dry the plastic after painting at a temperature of 18-60˚C, this depends mainly on the thickness of the applied layer. For example, with a thickness of 90-120 microns, drying at a temperature of 50˚C and a humidity of 65% can last about 3 hours. Polypropylenes and polyamides can be dried at a temperature of 100˚C in 20 minutes.
- The paint dries completely (polymerizes) plastic surfaces in 5-7 days, but when temperature regime short, high humidity and a thick layer of paint, this time period can increase several times.
Aerosol paint
This is one of the most convenient. The capacity of the can is 400 mm, which is enough to paint windows, slopes and small parts. Thanks to the wide variety ready-made shades, this method most often used in home renovation, although their price is more expensive than similar compositions in banks.
Tip: no need to think about how to remove paint from water-based plastic - treat it plain water, but you need to hurry, otherwise after drying the process will become much more complicated.
Most often, an acrylic universal composition is used, which dries quickly, making it possible to short time transform the interior of the room. The service life of aerosol paint exceeds three years.
Its convenience when applied to the selected surface also plays an important role. You don't need any for this additional tools, and also you do not need to have special professional skills. The layer under pressure is applied evenly to the plastic.
Tip: before you start work, you need to make sure that the room is well ventilated; it is best to open the windows for this. In addition, it is necessary to adhere to basic safety precautions - protect your eyes with special glasses and your respiratory organs with a paint respirator.
Conclusion
Applying paint to plastic products has its own peculiarity associated with the surface property. Before starting work, you should determine its characteristics and select the appropriate materials for the process. The video in this article will help you find additional information on this topic.
