The composition and types of paints in plastic canisters, how to apply the spray correctly

Plastic products are usually dyed at the production stage. However, sometimes it becomes necessary to repaint the surface. This is necessary to change its appearance or restore an old coating. To achieve the desired results, you can use special paints in plastic canisters. These substances have a special composition and perfectly fit the surface of the product.

Spray paints for plastic: features and specifications

In order for the coloring of the plastic to be beautiful and even, it is important to choose the right dye and strictly follow the recommendations for its application.

Composition and form of release

Spray paints are available in cans. These materials differ significantly in composition. They can have the following components:

• epoxy resins;
• acrylic base;
• oil ingredients;
• pigments and fillers;
• aqueous solutions.

Scope

Sprays for plastic products can be used in various fields. They can be used to restore objects that have lost their attractive appearance. Also, these materials are suitable for interior decoration. With their help, it is possible to give the product additional strength characteristics - for example, to increase abrasion resistance or to increase moisture resistance parameters.

Aerosols are often used to paint plastic car parts.

All of them are easy to use and do not require any specific skills. This allows the surface to be painted quickly and economically.

Advantages and disadvantages of paint material

Aerosol dyes are considered highly desirable materials due to their many benefits. The main advantages of these funds are:

• No need for additional painting tools.
• Convenience and ease of use.
• The ability to achieve beautiful, even coverage.
• No need for specific storage conditions. Even paint residue does not dry. They can be stored for a long time.
• Can be used for uniform coloring or decorating.
• Variety of shades. There are also on sale dyes that allow you to simulate the structure of different materials - metal or wood.
• Fade resistant. The painted surface retains its ideal appearance for a long time.
• Economic consumption. A pot of paint is enough for a long time.

At the same time, spray paints have some drawbacks. These include in particular the following:

• Lack of dye options. This minus is considered very conditional. Coloring sprays are available in a variety of shades. Therefore, choosing the right tone will not be difficult.If there is a need for a complex color, dyers can create it and fill it in a spray can.
• Risk of drops. Typically, this problem occurs when the required skills are not available. In this case, before painting the product, it is worth practicing on a small piece of plastic of a similar structure.
• Wide spray area. If you need to paint a small area, the rest of the fragments should be protected with masking tape.
• The inability to regulate the consistency of enamel. Therefore, you have to deal with a solution of a certain density.
• The ability to paint external surfaces only under specific conditions. This should be done in warm, calm weather.

Coating drying time and durability

The speed of drying of the surface depends on the structure of the material to be treated, the type and composition of the spray, the conditions of its storage and application, and the number of layers.

Thus, it takes from 40 minutes to 3 hours to dry the acrylic layer. Alkyd mixtures dry in 10-15 minutes. With the multi-coat application of nitrocellulose or alkyd enamel, the drying time is:

• 1 layer - 20-25 minutes;
• 2nd layer - 6-7 hours;
• 3rd layer - 24 hours.

Varieties and recommendations for choice

Aerosol dyes are of different types:

• Polymer - combine the functions of a primer and paint. Such substances are characterized by a high degree of adhesion. They do not require the prior application of a primer coat.
• Resistant to damage - characterized by a high degree of resistance. In the composition of such funds, polyurethane components and acrylates are introduced. They are used for application on surfaces exposed to high mechanical stress.
• Structural - after drying, they form a beautiful surface with a slight roughness. This hides the defects that appear on the plastic. The use of structural materials makes it possible to achieve an unusual decorative effect.
• Soft touch - this dye gives a velvety surface. Objects covered with such enamel give a feeling of softness and comfort.
• Monad - used for PVC plastic. They are characterized by a high degree of adhesion and are characterized by resistance to UV rays.

A large number of substances for coloring plastic allows you to choose the best option suitable for a specific type of surface. In this case, the following criteria must be taken into account:

• Basis of compliance. The instructions usually contain information regarding the type of plastic that can be treated with a certain agent.
• The appearance of the painted surface. When choosing a material, you need to take into account your preferences and the desired result. The moisture resistance of the composition is not negligible.
• Water resistance parameters. Acrylic dyes for plastic are considered the best option. Once dry, they help form an extra protective film that can be processed. However, in high humidity conditions, the additives cannot be removed. In most cases, polyurethane types are used. They have a high degree of water resistance.
• Propagation and masking power settings. The density and evenness of the layer of material on the painted surface depends on this.
• Base compatibility. The plastic colorant should match the material itself or the primer applied to the surface. If this recommendation is violated, the coating will quickly crack.
• Membership. Most formulations provide good adhesion to work surfaces.However, it is important to take into account the composition of the material and the fineness of the plastic to be painted.

Specificity of use

Surface preparation

To properly paint the surface, you need to pay attention to its preparation. It includes the following steps:

• Surface cleaning. Before painting, the plastic should be washed with water and detergent. To get rid of deep dirt, it is allowed to use a stiff brush. Don't be afraid to damage the plastic. With subsequent sanding and enamel application, it will be possible to level the surface. If you don't get rid of all the contaminants, the dye will sit unevenly. As a result, the surface will crack or become covered with bubbles. After the cleaning procedures are completed, the surface should be rinsed with clean water and thoroughly dried.
• Sharpening. To get rid of small roughness, it is worth using fine-grained sandpaper. For large cracks or dents on the surface, it is recommended to use a plastic filler.
• Degreasing. Greasy stains lead to poor adhesion of the enamel to the support. To eliminate them, it is worth using special degreasers. Alcohol-based products do not need to be rinsed off. Other substances should be removed with clean water. After that, the surface should be well dried.
• Padding. This procedure is not always necessary.To determine if a primer is needed, place the plastic product in a large container of water. If it has sunk, no priming is necessary. The additional application of a primer improves the adhesion of the enamel to the base.

Dyeing

Aerosol dyes form a fine suspension in the air, which accumulates on the object to be painted and on other surfaces. Additionally, there is a risk of small dye particles getting into the eyes or respiratory system. To avoid problems, it is recommended to do the following:

• Cover surfaces not intended to be painted.
• Hard-to-reach places that do not need to be painted should be sealed with masking tape.
• During work, use personal protective equipment - gloves, respirator, goggles.

After the preparatory work, the surface can be painted. To do this, it is recommended to proceed as follows:

• Shake the enamel box for 30-40 seconds to mix the dye.
• Remove the cap and release a spray of paint - you can use cardboard as a base. Air can accumulate in the sprayer. As a result, the first pieces of paint will fly off unevenly.
• At the time of the beginning of the release of the substance from the box, it is worth starting to paint the plastic.
• When spraying, the hand should be moved with smooth movements, without lingering in one place for a long time. In case of prolonged staining of an area, there is a risk of drops.
• It is necessary to keep the aerosol at a distance of 20-30 centimeters from the surface.
• After applying the first layer, the material must be dried for half an hour. Then you need to repaint the plastic.Apply the third and following coats if necessary.

Finishing

Although spray paints dry quickly, you can start using the product only after a day. During this time, complete polymerization of the enamel will occur, which will increase the strength of the decorative layer. If you want to achieve a metallic effect, you need to apply a special dye to the plastic.

Material consumption per 1 square meter

Spray consumption is about 200-300 milliliters per square meter. But this parameter is influenced by many factors. These include in particular the following:

• The quality of the material. The composition of the paint affects the quality of the application. Therefore, it is important to buy sprays from trusted manufacturers.
• Paint color. The lighter the aerosol, the higher its consumption. Many coats will need to be applied to achieve an even shade.
• Surface shadow. The darker the plastic, the more coats of paint you need to apply to change the shade. This is especially true when repainting dark surfaces over light surfaces.
• Absorbent characteristics of the material. The consumption of the substance is directly affected by the structure of the plastic. Highly absorbent surfaces will absorb aerosols quite strongly. Therefore, for a high-quality coating, more paint is needed.

Expert advice for economical use

To obtain a high-quality cover, it is recommended to follow these rules:

• Buy bobbins that have replaceable tips. They make it possible to adjust the width of the ink jet.
• It is necessary to apply a new layer after the complete drying of the previous one.
• If frequent use of the product is planned, it is worth applying more layers.

Security engineering

The paints in the canisters are under pressure, so it is forbidden to fill them yourself. Also, do not open, set fire to or puncture the container. The spray should not be stored near heat sources or left in the sun. Storing leftover paint works well in dark areas that aren't subject to heat.

Spray paint is ideal for painting plastic objects. In this case, it is important to choose the right composition and follow the application instructions. Compliance with security measures is also important.
