Finally, after painting plastic with acrylic paint, you may want to seal it with a clear sealer to finish the procedure, although this is not always necessary depending on the surface you are painting.

Step 1: Prepare the Surface

Before you begin spraying the surfaces, you must first ensure that the surfaces are clean. Utilizing mild detergent soapy water, you may thoroughly clean the whole plastic surface. Make sure that all the dirt, grime, and residues have been removed.

If you are using standard spray paint, such as those that are not intended for use on plastic materials, priming the surface is necessary before painting. There are a variety of primers commercially available that are designed specifically for use on plastic surfaces. Once the primer has been applied, let it dry completely before painting.

The primer doesn’t need to have the same color as the paint for it to work. If, on the other hand, you manage to come across a primer that is the same color as the paint, you can use it. Consequently, while picking a primer, exercise caution since you may wind up selecting a primer that is darker than the color you are painting. It is generally recommended that you use a clear primer.
