Preparation of plastics for painting at home
Before applying the paint on plastic, it must be prepared. Do this by following the step-by-step instructions and following a clear sequence of actions.
Step 1. Using a solvent, degrease the plastic object by wiping it.
Step 2. To avoid dust and small debris after painting, it must be treated with antistatic agent.
Step 3. If the item is old and has some minor defects, they can be corrected by applying the putty.
Step 4. In order to remove all cracks and crevices, the object is rubbed with sandpaper. It should be remembered that the sandpaper should be selected moisture-proof, because the grouting process must be carried out with water.
Step 5. Dry the plastic and degrease it again.
Step 6. We will ground the surface in several layers.
Step 7. After complete drying of the primer, it should be wiped with sandpaper No. 400-500, this is necessary for matting.

The choice of paint for self-dyeing plastic
Not every paint is ideal for plastic, if it is not chosen correctly, then when painting, the paint will lie flat on the surface not evenly. You can buy paint for plastic in a special store, it is also sold in cans and other containers designed for application with a brush.
For plastic, aerosol paints are ideal, they are sold in cans, which makes the application as convenient as possible. To work with the spray can not need additional tools, such as a roller or a brush. Such paint beautifully stains objects even in hard-to-reach places.
It should also be noted that this paint dries quickly and is less prone to fading and destructive actions than others. There is a huge selection of colors for aerosol paint, this will make it easy to pick the right shade. Not completely used in the can, the paint will be stored for a long time, and will not exude a smell.
Having a number of advantages over other types of paints, aerosol also has its drawbacks. The main drawback is that it is almost impossible to mix colors and get a clear boundary when painting, it is also impossible to reduce the density of the paint.
How to paint plastic on your own
Painting plastic products is not an easy task and very similar to the usual painting. Before painting, you should pay attention to the temperature of the paint and plastic product itself - it should be the same, about 20-23 degrees. And the humidity of the room should not exceed 80%.
With a brush or balloon the surface will be painted, it should be remembered that the paint should be distributed evenly in 2-3 layers, making more layers - the formation of streaks is possible. Before applying each layer, the product should be allowed to dry well, but only then proceed to painting the next one. If more layers are applied to the plastic, the product should be allowed more time to dry.
To give a shiny plastic surface, a sealant with a special shiny effect is used. Apply it in exactly the same way as the paint, letting the product dry completely.
After painting, the plastic must dry at a temperature of 17 to 60 degrees Celsius and a humidity of about 65%.In time it will take 3-4 hours. The large thickness of the paint layer can increase the drying time.
