Priming any surface before painting is a necessary stage in the classical technology of painting work. Plastic surfaces are the most whimsical and not all paintwork and primer materials are compatible with them. Therefore, a primer for plastic should be designed specifically for this material. Before buying, you need to read the instructions and make sure that among the surfaces recommended for coating with enamel there is also plastic.
Today, the most common and convenient soil is considered to be quick-drying liquid primer-enamel on an acrylic basis. If you do not apply a layer of soil before painting the plastic surface, then such a coloring will be short-lived. Subsequently, after a short period of time, the paint layer will become cracked and the paint will gradually peel off. The product will acquire an extremely unsightly appearance.

Primer enamel is distinguished by its remarkable ability to create adhesion to the surface of plastic products. In addition, before applying it, plastic is not required to be treated with any other primers. The resulting film is characterized by increased strength and resistance to mechanical and chemical influences. This enamel is suitable for outdoor work related to painting plastic partsexposed to direct sunlight and precipitation. In addition, the acrylic primer-enamel has the ability to tolerate low temperatures without cracking and crumbling.
Using aerosolized enamel primer, you can quickly update the surfaces of plastic parts and give them a well-groomed appearance. This enamel primer is economical in consumption and, despite its liquid consistency, when applied to vertical surfaces, it adheres well to them without leaving sagging.
Enamel primer is sold ready to use. The industry offers the most diverse color palette of this material, so choosing the right color is easy.
Enamel goes on sale in the form of aerosol cans, which allows you to apply it easily and evenly on products with any surface shape.

Primer enamel as a primer is used:
- on any plastic (PVC, ABS plastic),
- polystyrene
- vinyl
- metals
- ceramics
- glass
- to a tree.
Due to its water-repellent properties, it can be used for outdoor work and indoors with high humidity.
Before applying an enamel primer to the plastic surface, you need to clean the product from the old layer of paint and varnish, all kinds of contaminants and oil stains.
Glossy surfaces must first be sanded. After that, after the surface dries, degrease.
So that during spraying of the aerosol surfaces from other materials are not stained, before using liquid primer-enamels they are covered with paper or film.The best air temperature for high-quality painting of plastic surfaces with enamel is between +15 and +35 degrees.
Apply enamel primer:
- Immediately before applying, spray the spray can. This is done so that settled particles of the composition are distributed evenly.
- Liquid enamel is applied from a distance of thirty centimeters from the surface of the product by aerosol spraying. Depending on the need, the parts are coated in 2-3 layers. The interval between the coatings is maintained, allowing the previous layer to completely dry. Before each staining, the contents of the aerosol can must be shaken.
- During the ongoing work, the spray can containing aerosol is held upside down. If instead of the composition gas began to flow, it should be returned to its original position.
Primer "Liquid plastic"
It can be used not only for coating plastic surfaces, but also for metal. It has high water repellent properties.

It is applied as necessary in one or two layers. It has such properties as durability, high strength, resistance to atmospheric precipitation, lies in an even layer, does not crack and does not peel off when exposed to negative temperatures.
The main rule that must be observed when using enamel primers for coating plastic surfaces: they must correspond to the type of plastic on which it is applied. And in the event that after staining will be stained, it is necessary that the paint and primer are compatible with each other.
