Not all types of plastic are compatible with paint, and vice versa, which is why you should identify the right types of paint that can be used to paint plastic.

Clean the plastic surface

Before beginning with the plastic painting process, it is important to clean your plastic products first. You can use liquid soap to completely remove any dirt or oils that might be present in the plastic surface. This makes sure your paint and primer would be able to stick without any issues. A great way to clean plastic is by washing them with dishwashing soap, as this can clean up all of the oils and dust present in the plastic.

After drying up the cleaned plastic, the next step is to apply a primer coat.

When painting plastic, it is important to keep in mind that different types of paint require different approaches. For spray paint, it is important to spray at least 10-12 inches away from the plastic. For acrylic paint, it is important to make sure you are not using a heavy amount of paint for each layer, as that can cause uneven surfaces. The same goes for paint markers, as excessive coloring can lead to drips and uneven surfaces as well. 

 

Dry and apply finishing touches

The final step of painting plastic is to wait for the paint to dry to apply the top coating. Adding a top coat to painted plastic provides it with a protective layer that would help protect it from dust, liquids, and prevent paint from chipping away. 

Topcoats come in a spray can form, which makes applying it very easy and quick. You can also apply decals and stickers on the surface of the plastic for added aesthetics as well, and then add the topcoat to keep them protected from wear and tear. After letting the top coat dry, you now have the finished product.

 

Key Takeaway

Painting plastic can be a challenge without the use of the right processes and paint. By following these handy steps, you would be able to add the best and most diverse set of colors to your plastic products.
