Tips & Techniques for Successfully Applying Spray Paint to Plastic
Knowing the right techniques and tips for successfully applying spray paint to plastic is important. From sanding the plastic surface and priming it before painting to cleaning it thoroughly before starting and understanding how to prepare plastic for paint, there are certain steps you need to take to get the best results.
Clean the plastic surface
Before painting a plastic surface, ensure the surface is clean. You can use a detergent or rubbing alcohol to remove dirt and other residues from the plastic surface. This will ensure that the paint adheres properly, lasts longer without chipping or fading, and also help create a smoother finish for your project.
Sand the plastic surface
Sanding the plastic surface is necessary to ensure the primer and paint adhere properly. Use a fine-grit sanding block and apply gentle pressure when sanding the surface to coarsen the surface, enabling both the primer and paint to stick better.
Spray From a Distance
Spraying from a distance is an important technique to ensure the coat of paint is even and uniform. The ideal distance to spray from is usually ten inches away, ensuring the paint does not get too thick in one area or too thin in another.
It also helps to reduce the amount of overspray and create a smoother finish. Spraying too close can lead to uneven coats, which can be difficult to fix without starting over again.
Apply a primer
Primer is an important step in any painting project and can make all the difference between a successful and a failed paint job. Primers are designed to protect the surface from damage, prevent color fading, peeling, or flaking, and provide a better base for the paint to stick to.
Remember to choose the right primer for your project, as it can help you achieve better results with less time and effort.
Shake
Always remember that the paint, thinner and propellant must be mixed properly for the best results. That’s why it’s essential to shake the can before spray painting. By shaking the can, you mix the paint, thinner and propellant so that they are evenly distributed when applied. It will ensure you get even coverage with no streaks or patches of paint on your surface.
Repair the damages
Check for and repair any damages before you start spray painting. It ensures that the paint job looks its best and lasts longer. The best way to repair damages is to use plastic-recommended adhesives or soldiering. Adhesives are used for minor repairs, such as cracks and chips, while soldering is best for larger cracks and holes. Both methods are easy to use and can help you get the perfect finish when spray painting.
Let the paint dry
let the paint dry after spray painting for the paint to cure fully. It takes time for the paint to harden and become resistant to scratches, chips, and other wear and tear. Therefore, it is recommended that you let the painted plastic item cure for 24 hours before using it. Curing helps your item look its best for longer and also helps protect it from damage.
How To Spray Paint Plastic?

The steps
Clean the plastic surface
The best way to clean plastic is to pour rubbing alcohol onto a rag and scrub the surface. Cleaning the surface removes dirt, debris, and any oils or waxes that may be present on the surface of the plastic. Once you have scrubbed away all of these contaminants, wash with a mild detergent and let it completely dry before you start spray painting.
Sand the plastic surface
Sanding the surface is a crucial step in readying it for painting. Use fine-grit sandpaper (220) to roughen the surface so the primer can stick better. After sanding, wipe the surface with a wet rag and let it dry completely before applying primer. Sanding also helps remove dirt, dust, or other particles affecting the paint’s finish.
Apply the primer
Applying plastic primer helps create an even surface and ensures the paint will adhere better. Shake the primer before applying it to the surface for the best results. One thin coat of primer is usually enough, but you can apply a second coat if needed.
Spray paint the plastic
Before applying the spray paint, shake the can for at least a minute to ensure that the paint is properly mixed. Apply 3 to 4 coats of paint for maximum coverage, which will help ensure your project looks professional and lasts longer.
After every coat, let the paint dry for 15 minutes before applying the subsequent coats. If you intend to create a pattern, use masking tape to cover the areas you don’t want to paint. Finally, follow the guidelines provided by the manufacturer for the best results.
Finish with a clear sealer
A sealer is the final step in painting projects and is essential for protecting the paint from wear and tear. It also gives a finished look to any outdoor plastic objects that have been painted. Applying a sealer after painting will ensure your project looks its best for years. The right sealer can help protect against UV rays, moisture, and other elements of nature that can damage your work.
If you have accidentally painted on plastic surfaces that you didn’t want to stain or paint, don’t worry. You can remove them with household items such as vegetable oil or rubbing alcohol.
