The material is sold ready-made in jars or tubes, from which it can be easily applied directly to the surface to be repaired. Before applying liquid plastic, you need to clean the structure from all contaminants and rub the entire surface with fine abrasive sandpaper.

How to choose a degreaser and primer
The choice of degreasing and priming agent is important. They will ensure a high-quality result. Suitable for degreasing:
- Acetone;
- Vinegar;
- Petrol.
You can resort to ready-made types, here they look at the constituent components so that they do not differ from the composition of the paint, this can lead to a reaction.
The degreaser is used on a matte finish; if the surface has a smooth structure, it must be sanded with sandpaper.
Plastic has a low adhesion rate, for this reason the primer solution should be selected with a high degree of adhesion and elasticity.
Professionals note that acrylic primer works better with plastic materials.
The choice of paint and varnish material is made taking into account home conditions and the preferences of the owners. If the item will be subjected to mechanical stress, then it is worth purchasing paints that are resistant to them. For example, when they are going to place flowers in pots on the windowsills.
To obtain a brighter shade, painting should be done in several layers. The factor is also taken into account when choosing. The drying time of the coating is also important; when not a single layer is done, the repair period can increase significantly.
Aerosol
Aerosols are convenient to use; spraying helps to obtain uniform coverage. Spray paints are characterized by a high degree of adhesion to plastic, reliability and resistance to mechanical stress. The following advantages are noted:
- Ease of use;
- No need to buy tools;
- Wide range of colors: brown, black, red, green, gold and others.
How to choose a primer for plastic?
