Wear protective gear

Before you begin spray painting, it is important to put on the proper protective gear. This includes a face mask to avoid inhaling fumes, gloves to avoid getting paint on your hands, and goggles to protect your eyes from the paint.

Once you have all of your gear on, you can begin spraying the plastic. Start by holding the can about 6 inches away from the surface and moving it in a steady back-and-forth motion.

Overlap your strokes to ensure even coverage. After the first coat, let the paint dry for about an hour before applying a second coat.

Prepare the area around

Consider the environment in which the painting will take place. If it is a high-humidity environment, the paint may not dry properly and could end up being a disaster.

With all of these things in mind, make sure to test the paint on a small area of the abs plastic before proceeding with the project.

Select a well-ventilated area so air can circulate properly and air-dry the paint

Sand the plastic

If you want to spray paint abs plastic, you need to sand the plastic with fine sandpaper first. This will create a smooth surface for the paint to adhere to.

Make sure to sand in the same direction as the grain of the plastic. Once you’ve sanded the entire surface, wipe off any dust with a damp cloth. Then you’re ready to spray paint your abs plastic!

Apply primer

It is important to apply primer before spray painting abs plastic. This will help to prevent the paint from peeling and ensure a smooth, even finish.

Then, apply a primer specifically designed for use on abs plastic. Finally, spray the paint onto the primed surface.

  • Allow the paint to dry for about 30 minutes before applying a second coat, if desired.
  • Once the paint is completely dry, you can reassemble any parts or pieces that were removed prior to painting.

Clean up the area

When you’re finished spray painting, it’s important to clean up the area around you. Here’s how to do it:

  1. First, remove any excess paint from your brush or roller.
  2. Next, use a clean, damp cloth to wipe down the area around you.
  3. Finally, dispose of any paint cans or other materials properly.

By following these simple steps, you’ll ensure that your work area is clean and safe.


Yes, some manufacturers recommend the use of a primer to ensure the best possible bond between the plastic and the adhesive.

There are a few different types of primers that can be used on ABS plastic, but lacquer is generally considered to be the best option. This is because lacquer provides a smooth, even surface that is perfect for painting or applying other finishes. Additionally, lacquer is very durable and can withstand a lot of wear and tear.

For most plastics, two coats of primer should be enough. However, if you’re working with a particularly porous type of plastic, you may need to use three coats of primer to get a good seal.

If you don’t paint over primer, it will eventually break down and deteriorate. This is because the primer is designed to be a temporary protective layer that will eventually be covered up by paint.

You should always let the primer dry on plastic for at least 15-20 minutes. This will ensure that the primer has a chance to properly adhere to the surface of the plastic and create a smooth, even finish.
