Oh, as often happens - a plastic thing could still serve, but for a long time use lost worthy appearance: frayed, peeled, unpleasant scratches and stains appeared on the surface. It also happens that in the store you have chosen the shape and size you need, but the item has a completely inappropriate color. And about plastic bumpers cars and there is nothing to say. What a bumper! Sometimes you have to change the entire interior color. How to paint plastic? - Paint! What kind of paint is needed? – Paint on plastic! How to choose and paint? - That's what we'll talk about.
Water-based composition
Plastic can be painted with water-based polyurethane-acrylic paints. Simpler - LKM (paint and varnish material) on water based. Even simpler - acrylic enamel on the water.
Most often, such paints are two-component:
- The base part is the paint itself.
- Hardener is a universal solution specifically for acrylic water-based enamels, giving them chemical and mechanical resistance. The universal hardener itself is colorless and odorless.
Under the influence of this polymer, the paint takes on the properties of good varnish coating: decorative, layer uniformity, resistance to atmospheric and mechanical influences, fits perfectly, resistant to fading and ultraviolet rays.
These are compositions of special strength, which use polyurethane additives + acrylates.
Acrylic paints for plastic, combining the functions of a primer and a dye, do not require special preliminary preparation of the painting surface itself. Of course, if it is not very dirty. Painting plastic parts and painting plastic even large area exposed to strong mechanical stress, these types of paint are the right solution.
Matte soft-touch paint
Items that we use frequently should be pleasant to hold in our hands. They should please not only the eye, but also the hand. What paint should I use to paint the plastic of a mobile phone or computer mouse, as well as lighters and pens, a flash card and furniture fittings? How can you paint eyeglass cases and cosmetic boxes? hand tool and a children's toy? What plastic paint will decorate a modest flashlight or high-precision binoculars? – Matte soft-touch paint!
This matte and soft-to-touch material is not only pleasant, it also perfectly absorbs light or sound, and is suitable for making a product decorative. The most popular color of two-component paint with a matte soft-touch shade is black, however, the manufacturer can offer other, brighter and more contrasting colors.

Soft-touch paint for plastic can be used not only for plastic, but it must be taken into account that when painting other surfaces (other substrates) with it, you will have to look for other primers corresponding to the material being painted.
Do not prime any surface to be painted with solutions containing copper sulfate! CuSO4·5H2O forms chemical compounds with acrylic paints that significantly worsen the properties of water-based acrylic enamels, and also deprives them of adhesion (adhesion of surfaces of dissimilar bodies). But thanks to the high adhesion, painting plastic with these paints is so valuable!
Very often, soft-touch is used when decorating a car and its interior parts, because... It not only has exceptional wear resistance, but also makes it easy to paint vertical surfaces, at the same time smoothing out visually sharp corners.
Water-based polyurethane-acrylic paints for PVC
You can paint the plastic with water-based polyurethane-acrylic paints. Conventional, without giving a matte effect, these compositions are used for painting large surfaces. What can be painted? – Siding and sandwich panels, rigid PVC and building profiles, metal-plastic doors and window frames.
These are quality paints! They form a water-repellent dense film, wear-resistant and “not prone” to stickiness, giving the products additional hardness and maintaining their elasticity and elasticity. The indicators for resistance to defect formation and anti-blocking (technological resistance to the adhesion of surfaces to each other after application and drying without loss of original decorative effect) of PVC paints are simply excellent.
Service life is guaranteed to be at least 7 years, but in reality it is much longer. In essence, PVC is colorless, because it's just a thermoplastic polymer of vinyl chloride - a plastic that needs to be given bright, rich colors to make it "pleasant to the eye."
It is for this “joy” that plastic painting compositions are used, consisting of two components (like soft-touch):
- Base acrylic paint of the desired color - paste.
- A thick, milky white liquid – a hardener – with properties that can give paint a soft, pastel tint or, conversely, color painted PVC (and with them) with all the colors of the rainbow.
If texture additives are added to the base paste, then the plastic products themselves will acquire various texture effects (wood, rough plaster, fabric, etc.).
Aerosol paints for plastic
Don’t think that painting plastics from spray cans is only available to decorating gurus. Ease of application, big choice colors, the lack of hassle with mixing and diluting makes aerosol paints and varnishes very affordable means. They are suitable even for a person who is thinking for the first time about such a highly artistic task as repainting or updating plastic with his own hands.

Polyurethane-acrylic enamel in aerosol cans is produced in 2 types:
- The already well-known soft-touch is a structural paint that, when dry, gives a slightly rough, “soft” surface that allows you to hide minor flaws in the painted surface. It is also perfect for creating original, cozy “home” decor.
- Paint the plastic in a glossy bright color that reflects Sun rays, allow monad enamels intended to paint PVC.
This assortment allows you to choose the right aerosol that is needed for one or another type of plastic.
The advantages of the aerosol are obvious:
- the balloon does not require the use of additional molar instruments (brushes, rollers, etc.);
- convenient and easy to use;
- the paint lays down in an even, smooth layer on any surface to be painted;
- the structure of the paint allows you to imitate any desired surface (metal, wood, leather, fabric, mirror);
- colors are not subject to fading for a long time;
- unspent remains can be stored in the cylinder for a long time;
- economical for wide areas of spraying;
- when repainting the product, it easily covers the previous layer.
So that not only you, but also those who will “accept” your work will enjoy painting, we paint plastic according to all the rules. We'll look at how to properly paint plastic using an aerosol below.
Spray painting
How to paint plastic with paint from a can? We keep the aerosol at a distance of 25-30 cm, constantly moving it, without stopping at one point in order to avoid unsightly smudges. It is best to practice on an unnecessary piece or in a place where traces of training will be least noticeable.
Since you have to coat it twice, we don't have to worry about getting a perfect finish the first time. Let the layer be thin with gaps, this will be corrected the second time.
Let the paint dry naturally for at least 30-40 minutes. Apply a second final coat. Examine the fruits of your labors from all sides and, if necessary, “patch up” the areas that are poorly painted by re-applying paint to them after 30 minutes.
Leave the product until completely dry (polymerization paint coating) - 2-3 days. If you decide to change the color of the heating pipes, then most likely you will fail. If the plastic of the pipe is made of polyethylene, then it cannot be painted with polyurethane-acrylic enamel.
The temperature of the paint and the product must be equal. You can also use products painted with paints and varnishes on the street (for example, garden furniture at the dacha or flowerpots at the entrance). When painting soft-touch, make sure that no drops of water fall on the surface, or that the product is not subjected to a sharp temperature change.
Industrial painting
Industrial “gross” coating with water-based polyurethane-acrylic paints is produced by spraying the dye onto the edges and vertical surfaces of the material with a thickness of 80-120 microns. This is quite enough if you apply the paint after treating it with a special PVC cleaner, which removes electrostatic stress from the surface, and also degreases it so that the paint does not burst or peel off.

After the actual painting of the plastic is completed, the product is subjected to forced drying at +50 degrees continuously for 2-6 hours. Drying time depends on the filler and texture of the paint; each type has its own mode.
The answer to the question of how to paint plastic correctly has already been almost received; it remains to add that before painting, the mixture of base and hardener is thoroughly and intensively mixed, achieving absolute homogeneity, if necessary, diluting it with water to obtain industrial viscosity.
This paint can be used for 3-5 hours after preparation; it is applied using a spray bottle and forms a durable coating that is easily cleaned with water.
How to paint plastic at home? Is it possible? - Yes! There are various aerosol enamels for this, you just need to find the one that says: “for plastic surfaces or plastic.”
- The surface to be covered with an aerosol can must be clean of dirt and washed of grease. Ideally, you should use isopropyl alcohol, but regular dishwashing liquid will work fine.
- Decide on the type of plastic you are going to paint and, if necessary, select a suitable primer.
- You should not choose acetone-based paint for plastic, despite its attractive price. Acetone can corrode the plastic, and you will not get a beautiful, noble painted surface. Wait for warm, calm weather if working with paint indoors is not possible.
- When covering a large area, stock up immediately the right amount cylinders of the same batch. Cover the “extra” area with old sheets or newspapers (remember the wide spray spectrum). Shake the aerosol vigorously for a few seconds before starting coloring.
Protective clothing for working with paints
Important! The product to be painted must be dry. When painting, you should use protective equipment - wear a respirator, goggles and gloves.
Many car enthusiasts believe that painting plastic parts car is a simple procedure. However, this opinion is erroneous, because the plastic surface on which paint was applied with a brush or by spraying an aerosol can will quickly lose its original appearance, and the paint will crack and fall off within a short time after painting. Also, some types of plastic require preliminary preparation before painting, which involves thorough degreasing and priming.
Primer of plastic surfaces
Almost any plastic part is painted in several stages. However, it is worth remembering that the painting and drying procedure itself is The final stage, you first need to degrease the part and prime it. There are some types of plastic that do not require a primer as long as there are no visible chips or scratches. To determine this type of plastic, take a piece of plastic of the same type and throw it into the water; if it sinks, then there is no need to prime it. If such a piece does not sink and also burns without soot, these types of plastic require, at a minimum, the application of acrylic putty before painting.
And now in more detail about the methods of priming plastic parts of a car before painting. For example, you have parts that need to be painted. As already mentioned, some types of plastic are subject to mandatory application of a primer; if you have plastic that does not need to be primed, then you can get by with final putty and thorough degreasing of the surface, followed by painting in desired color. However, if you have plastic parts complex shape, it is very difficult to paint them well in a garage, otherwise they may be damaged. In this case, you need to contact specialists.
Now let's consider another option for painting a plastic part that needs to be given its original appearance after slight damage in the presence of small chips and scratches; in such cases, it is necessary to resort to applying a special primer for plastic, which will hide all defects. In this case, it is necessary to apply the primer to the previously degreased surface in thin layers until all defects are hidden, however, it should be remembered that applying too thick a layer is not permissible, otherwise the paint may crack during the period of operation of the part. When applying this primer correctly, it is not necessary to sand the surface, but before painting it is necessary to thoroughly degrease it.
If, after applying the primer, it is still necessary to carry out plastic surface, then it is better to do this with an abrasive of 240 and higher, and then repeat the application of the primer.
Sanding a plastic part after applying primer before painting
For final sanding, it is better to use 320 abrasive if you plan to paint with regular enamel. If metallized enamel is used to paint a plastic part, in this case it is necessary to use sanding in two stages and finally use 450 abrasive.
In the process of preparing for painting, it should be remembered that after applying each layer of primer, it is necessary to dry the surface and degrease before each application of the next layer.
Final sanding with fine abrasive must be done using water.
Putties for plastic can be used in one or two components, but the shade should be different from the shade of the paint.
What are plasticizers and acrylic paints?
In terms of complexity, the process of painting plastic parts is no different from painting metal elements car body. Painting plastic is done with a tool called a spray gun. coloring composition must consist of enamel and plasticizer. Painting with aerosol paints is also possible, but it is worth remembering that the surface will not be elastic enough, which will subsequently lead to cracks.
There are situations when motorists and owners of houses or apartments decide to change the usual interior and color of a room or car, as a result of which they face interest Ask: how to paint plastic and what materials can be used for this?
Painting plastic
As a rule, the technology for performing painting work for any surface remains the same. But besides general requirements, there are also some subtleties, without which it is simply impossible to perform a high-quality finish. That's why such additional information It's worth taking into account.
Types of paints for PVC products
Painting plastic
On the market today paint and varnish materials there is a huge variety of paints that can be used to cover high-quality pvc structures. They can be either in the form of an aerosol or spray, or in the form of conventional paint for application with a brush or roller, which can be either matte, glossy or pearlescent.
Technical characteristics of paints suitable for plastic are given in the table.
- Maraplane – wonderful example for work on PVC structures.
Finishing work with this paint is carried out using a roller, sponge, brush or spray. If such paint on plastic is applied at a temperature of 20 o C, then after 20 minutes you can begin applying a second layer, and after another 4-5 hours the product will be absolutely ready for use. Maraplan paint is very resistant to ultraviolet rays and is also resistant to mechanical damage. But it is better not to subject the film to mechanical overload until the coating has completely dried.
- Rainbow-180 is an absolutely white glossy coating for PVC sheets.
This plastic paint is used to decorate windows, window sills, baseboards and other hard plastic, which can be used for both exterior and interior finishing. In addition to PVC, the aerosol is also suitable various surfaces, as well as putty and wood. You can work with this paint at 15-75 o C, and the next layer can be applied after 1-2 hours. This paint is great for exterior decoration.
- Snezhka is an acrylic-based enamel for decorative framing of hard PVC and other materials.
According to advice experienced craftsmen, it is better to apply this coating in 2 layers. After applying the paint, the surface of the plastic will be matte after 5-15 hours, and this coating can be used for both external and internal work.
- Akmilight is a coating that can glow in dark room blue or green.
We paint plastic with our own hands
This paint is widely used for work on PVC, ABS, polystyrene and polypropylene. She has increased level strength and weather resistance. This paint has proven itself well in the restoration of pots, furniture, souvenirs, window and door blocks using a spray or by dipping from 1 to 3 layers, as indicated in the instructions for use of the material. Before you start painting work, as well as during the process of their implementation, the paint must be thoroughly mixed all the time, because additives tend to settle, and the time for drying the finish varies between 2-4 hours.
- Gamma – acrylic paint, presented as an aerosol.
In the palette of this finishing material There are about 25 shades that can be applied to plastic, wood and steel, and it is also great as a spray for applying graffiti. Obtained in this way decorative coating will be weatherproof, have deep color and subdued shine. For achievement best result it is better to choose a white base (if we're talking about about the fluorescent version - this requirement is mandatory). Sometimes it is necessary to apply the material in 2 layers to increase contrast and enhance color, but reapplying the material is allowed only after 30 minutes, so that the bottom coating has time to dry properly.
It is also worth highlighting a separate category of paints that contain chromium. Chrome is also called " mirror paint» most relevant in mechanical engineering. To apply chromium to the surface of a product, both an aerosol and a galvanic method are used, the difference will be almost imperceptible.
Today, finishes such as chrome (especially in aerosol form) are becoming increasingly popular. Chrome, with its mirror-like features, captivates the eyes of passers-by, which is why motos and car enthusiasts love to use it.
In addition to high strength, chrome can withstand high temperature changes, and it does not matter whether an aerosol is used for application or whether the painting was done at the factory.
Chrome can be gold or silver in color, which can also be an interesting detail when decorating the interior of your apartment. In addition, chromium has excellent physical, chemical features and affordable price.
How is painting work done?
Before starting painting work, the plastic must be pre-cleaned and dried, because it can only be painted if there is a good level of adhesion, which can only be achieved on a degreased and cleaned base.
To prepare the surface and clean it, under no circumstances use familiar solvents or the familiar white spirit. Today, the market offers a wide range of specialized compounds for cleaning plastic.
Please note that not every plastic needs a primer, and sometimes it happens with precision, and, on the contrary, it is impossible to do without it. To understand how to act in specific situation, there are 2 simple verification methods:
- Buoyancy
To do this check, take a piece of plastic and put it in water. If it starts to sink, you won't need primer. If, on the contrary, the material lies on the surface of the water, there will be no need for a primer.
- Combustion
If during arson the material begins to smoke, there is no need to apply a primer, but if it burns “cleanly,” applying a layer of primer is inevitable.
If you need to paint a part that is not new, it may need to be sanded, which will require sandpaper number 320-400 and water to remove cracks and cracks.
We paint plastic parts ourselves
When painting, paint is applied to the surface with brushes or paint rollers on a wool or mohair base. Aerosols and sprays can also be used for small-scale production.
We don’t know about you, but we at the editorial office want to spend good summer evenings on the lawn near our house. Imagine how great it is to sit in a garden or country house with a drink in your hand and look at nature... Only you are sure that you have a nice place, where to sit? Lots of people have these cheap plastic chairs. Before you get rid of them, you can try to fix them! Who knew you could spray paint and have chairs looking beautiful in about an hour? It took about an hour to completely make 6 chairs. So here's how it went:
- We need spray paint that says it's suitable for plastic. You choose the shade yourself, to your taste, of course. Consumption is approximately 1 can per 1 chair. In the example, Painter's Touch paint was used in the Côte d'Azur color and Green apple. If the chair has minor defects, you can choose paint with a hammer effect, this will slightly refresh the surface.
Don't worry too much about shine. 2 were used here different coatings: gloss and satin - but the surface turned out to be approximately the same. So just choose the paint according to its shade.
How to paint plastic chairs
Clean them up: In the example, the chairs were simply washed with a hose under low pressure. If you have the opportunity to wash them in the bathroom with dishwashing detergent, it won’t be superfluous.
Dry them: We let the chairs dry completely in the sun.
Prepare your surroundings: I don't like to clean up after myself after a project, so I try to avoid getting dirty beforehand. It is better to paint directly on the lawn (before mowing, because traces will still remain) or line the balcony/veranda with newspapers, protective film or old rags.
Paint them: Apply to each chair thin layer paints. Hold the can at a distance of about 25 centimeters from the surface of the chair and do not let the can direct the paint to one point for a long time. It must be constantly moved while spraying. Don't worry about getting full coverage during your first coat of paint.
- Advice. It is better to start with the part of the chair that is hidden from view to practice on it. But you don't have to paint the bottom at all.
Second layer: The first coat should be allowed to dry for 30 minutes before applying the second coat. (I believe the instructions say to wait a little longer, but we're all impatient here).
Final coating: You may have a few spots or uneven spots here and there, and the second coat is the time to touch it up. Paint the chair, then walk around it and inspect it from all sides to make sure all visible parts are painted.
Let them dry COMPLETELY.: The only thing worse than the original dull color is smudged paint. So I let them dry for the rest of the day and then waited a couple of days before letting anyone sit on the freshly painted chair.
This is what the chairs looked like after a year. Green paint faded (this was in Southern California, and these chairs were often in the sun).
In response to the question “Is it possible to paint plastic furniture for the street with paint? We answer “Yes!” It works and it counts in a great way freshen up your backyard.
Often different plastic products, which could serve their owners for a long time, lose their original appearance. Noticeable cracks appear on their surface, objects become too dull. Many people cannot decide which paint is best to choose for applying a new coat to things made of plastic.
Peculiarities
As of today construction market There are a huge variety of different types of paint for plastic. The choice depends on what kind of thing you are going to paint and what use it will have. After all, each individual type has its own advantages and disadvantages.
Many people think that painting plastic products at home is very simple. But actually it is not. It is the choice of coating and the application technology that determines how long the part will last. We must not forget that you need to pay attention to the type of plastic. Each individual type of this material has its own exceptional characteristics.
It should be noted that some types of plastic cannot be painted at all.
Objects made using polypropylene or polyethylene have a similar property. The paint from such materials will simply come off. Therefore, it is almost impossible to coat metal-plastic pipes which are made using polyethylene.
Automotive plastics deserve special attention. For some types of such materials, it is necessary to apply the first layer of a special primer-concentrate before painting; for other types, this procedure is completely optional. Today, experts can offer a considerable number of ways to determine the type of material that requires coating with other intermediate layers.
Types and compositions
IN given time specialists can offer consumers a large variety of absolutely different types paints for plastic. They all differ from each other in their characteristics and composition.
These include:
- Waterproof acrylic enamel;
- Aerosol paint;
- Vinyl paint;
- Structural paint;
- Matte soft touch paint.
Waterproof acrylic
This type of material is the best option for plastic. Enamel has everything necessary qualities. It should also be noted that it is quite simple to apply. Acrylic paint water-based is one of the most durable. You can often see such a coating with a bright glossy tint.
Aerosol
Recently, many consumers prefer this particular coating. This paint is perfect for textured surfaces. Different types aerosols can give plastic a wide variety of shades (mirror, golden, silver). It is important to note that certain types of such material have antistatic properties.
Vinyl
It should be noted that this material is one of the most environmentally friendly. Another important characteristic is low cost. But vinyl paint cannot be called wear-resistant. It is completely unstable to moisture, wind and many other external factors.
Structural
Most often, this coating is used for automotive plastics. This paint gives surfaces a slightly rough textured finish. With its help you can special labor hide scratches and cracks.
Such an application will make the part durable and resistant to external factors (wind, dampness).
Soft touch
This matte paint Excellent for plastic products. It is very easy to apply. This material can give the plastic a pleasant matte tint. It is worth noting that such a base is quite pleasant to the touch. Most often, this type of coating is used when decorating street lamps, some mobile phones, binoculars.
Currently on the market building materials you can find completely different coloring compositions:
- Tactile. After application to plastic products, this composition allows you to leave a pleasant velvety base on the surface. This coating also allows you to make the part in an unusual matte shade. As a rule, soft touch paint has a tactile base, which is widely used for decorating various materials.
- Powder. It is important to note that paint with this composition may not be suitable for all types of plastic, but only for those that have high heat resistance. After all, the coating with a powder base is applied in special chambers under the influence of sufficiently high temperatures. Most often, instruments on boats, ships, and steamships are painted with this material to give them even greater strength and resistance to external mechanical damage.
- Abrasion resistant. Such compositions are based on special polyurethane resins, to which additional substances are added. All kinds of additives can make the material even stronger and harder. As a rule, paint with such a base is used for items subject to heavy loads.
- Structural. This composition is ideal for parts with noticeable scratches and damage. After all, paints with such compounds give surfaces a light, rough surface, with which you can easily hide all defects. These coatings are quite convenient for decorating items at home.
Colors
Today, experts can recommend to consumers a huge variety of paints in unusual colors. With the help of such coatings you can decorate almost any thing. The most original and interesting options are gold, brown, black, silver, bronze, silver paints.
Many designers advise using different decorative elements made of plastic paint, which gives the surface a chrome effect. This material can fit perfectly into many interiors and this coating is often used for automotive products.
There are paints that can give different objects a silver tint. They are also used to decorate automobile parts.
Application
Plastic paint is often used for chrome plating parts. Most often, such coatings are represented by various aerosols.
It is best to decorate windows and window sills using aerosols. This application will last quite a long time. The same base is perfect for painting fiberglass. It must be remembered that all kinds of enamels are not good option for similar items.
It is best to paint PVC products with waterproof acrylic enamel.
But it should be noted that before applying the main paint, it is necessary to cover the part with a layer of a special primer, otherwise the surface of the product will quickly lose its original appearance.
Which one to choose?
Today there is a wide variety of paints for plastic. But we must not forget that each type of plastic has its own specific type of coating. Therefore, before painting elements, study in detail the material from which the part is made, as well as the composition of the base on which you want to apply it.
