Our love-hate affair with plastic is a modern-day conundrum. No matter how much we detest plastic, it’s still an ubiquitous entity that makes up most of our lives.
And since we really can’t do much about plastic, we can surely upgrade the older pieces to reduce the environmental impact of producing more plastic.
Because of its smooth and non-porous nature, it’s nothing unimaginable to think of the question: Can you spray paint plastic?
Here’s your short and simple answer:
Yes, you can spray paint plastic, but you need to use a special type of spray paint that is specifically designed for plastic surfaces. Regular spray paint will not adhere properly to plastic and will likely peel off.
But we’re definitely not leaving you in the middle of nowhere. We’ve got some tricks up our sleeves to help you overcome the challenge of painting plastic that is notorious for being sleek and impermeable.
Let’s learn how you can be a part of the upcycling movement!
Supplies For Spray Painting Plastic
Just as they say, “A craftsman is only as good as his tools.”
Here are some supplies that you need to make your job easier:
- Spray paint: Choose a spray paint that is specifically designed for plastic. There are many different brands and colors of spray paint available, so you can find one that will match your project perfectly.
- Sandpaper: Sanding the plastic will help the paint adhere better. Use fine-grit sandpaper (180-220 grit) to avoid damaging the plastic.
- Primer: A good plastic Primer will provide a smooth and long-lasting finish to your spray paint.
- Drop cloths: Drop cloths will protect your work surface from overspray.
- Painter’s tape: Painter’s tape will help you create clean lines and prevent paint from getting where you don’t want it.
- Gloves: Gloves will protect your hands from the paint.
- Newspaper or cardboard: Newspaper or cardboard can be used to protect your work surface from overspray.
- Rags: Rags can be used to clean up spills and drips
- A well-ventilated area: Spray painting should be done in a well-ventilated area to avoid inhaling the fumes of the paint.
Steps to Spray Paint Plastic
Here are the basic steps that can help you upgrade all your older items to completely new:
Step 1: Preparing the Plastic Surface for Painting
Proper surface preparation is the key to a durable and flawless finish.
Start by cleaning the plastic surface thoroughly with soapy water to remove dirt, grease, and any existing paint or coatings. Once it’s squeaky clean, allow it to dry completely.
Next, it’s time to give that plastic surface a bit of a rough-up. Sanding creates a slightly textured surface, providing better ‘teeth’ for the paint to grip. Use fine-grit sandpaper and go easy – you don’t want to gouge the plastic.
Step 2: Apply a Layer of Primer
A layer of primer is important to avoid chip-off in the future.
Make sure to select a primer spray based on the size of the object you want to paint. Each primer spray bottle covers a specific square foot area.
Once you have the primer, shake the spray paint and apply one even coat on the plastic surface. After applying the coat, wait at least 10 minutes to let the primer dry (you can wait more depending upon the condition of the primer).
Choosing the Right Spray Paint for Plastic
Don’t just grab any can of spray paint from the hardware store. There are specific paints formulated for plastic surfaces, ensuring that your masterpiece won’t peel off after a few weeks.
Popular brands like Krylon Fusion, and Rust-Oleum Specialty Paint for Plastic are excellent choices. They’re designed to bond with plastic and provide long-lasting coverage.
When it comes to finish, the world is your oyster. Choose from gloss for a shiny finish, semi-gloss for a subtle shine, satin for a smooth, low-luster look, or matte for an eggshell-like finish.
Step 3: Spray Painting Technique: The Art of Light, Even Coats
Shake the can vigorously for at least a minute to ensure the paint is well mixed. Hold the can about 12 to 18 inches away from the plastic surface and move it steadily back and forth, keeping your hand level.
Apply light, even coats, rather than thick, gloppy ones. Thick coats can lead to drips, runs, and an uneven finish. Let each coat dry completely before applying the next.
Bonus Tips for Smooth Finish:
- Your spray bottle should be moving while applying the paint.
- Hold the spray bottle vertically and move it as you apply the paint, ensuring that each pass slightly overlaps the previous one for a smooth, even finish.
- If you’re new to spray painting, practice on cardboard or another spare surface to get the hang of it before painting your main project.
- Use painter’s tape to protect the areas you don’t want to paint for a picture-perfect look.
- Apply light, even coats, rather than thick, gloppy ones. Thick coats can lead to drips, runs, and an uneven finish. Let each coat dry completely before applying the next.
- For a smoother finish, lightly sand the final coat with fine-grit sandpaper once it’s completely dry. If you want to add extra protection and shine, apply a clear sealant.
Here’s a comprehensive guide on how you can avoid paint drips.
Step 4: Let the Paint Dry
Let the paint dry completely before applying another coat of spray paint. Drying times can vary from 10 to 30 minutes or longer, depending on the type of paint. Acrylic and oil paints, for example, may need several hours to fully dry.
To speed up the process, open the windows and door for good airflow. Always let each coat dry completely before adding another, as thicker coats will take longer to dry than thin ones.
Step 5: Seal the Deal
Now comes the fun part – adding color and style with your spray paint! Choose a color that complements the decor of your room or expresses your unique personality.
Apply the spray paint in thin, even coats. Allow each coat to dry completely before applying the next.
For a smoother finish, lightly sand the final coat with fine-grit sandpaper once it’s completely dry. If you want to add extra protection and shine, apply a clear sealant.
Can You Spray Paint Plastic Without Primer
We already know that it’s challenging for paints to adhere to plastics, and you need spray paint specifically designed for the purpose.
However, if you’re spray painting without plastic paint (sometimes that’s all you have and the project is too small to invest in another spray can), you need a medium to help normal spray paint adhere to the plastic’s non-porous surface.
And that medium is primer. Primer helps the paint adhere to the plastic and prevents it from chipping or peeling.
Although spray paint designed for plastic can indeed be used without a primer, we still recommend using one. It’s because primer serves not only to bond the paint to the plastic but also to ensure a smooth, chip-resistant finish.
Troubleshooting Common Spray Painting Issues
Even the most seasoned spray painters encounter hiccups along the way. Don’t panic – we’ve got solutions to common problems.
- If your paint is peeling, it’s likely due to poor surface preparation or using the wrong type of paint. Sand the surface again and start over with a primer specifically designed for plastic.
- Drips and runs can occur if you apply too much paint at once or move the can too slowly. Keep your coats light and move your hand steadily.
- Uneven coverage is often caused by spraying from too far away. Maintain a consistent distance between the spray can and the surface for more even results.
Overspray and Safety Precautions
Overspray, the mist of paint that goes beyond the intended target, can be a pesky problem. To minimize overspray, choose a well-ventilated area to work in and cover surrounding objects with drop cloths or plastic sheets.
When spray painting, it’s crucial to prioritize safety. Wear protective gear, including gloves, goggles, and a respirator, to avoid inhaling harmful fumes. Remember, spray paints are highly flammable, so stay away from fire or open flames.
Avoid exposing the plastic object to heat or direct sunlight. It’s best to spray paint indoors, but if you must paint outside, do so only when the weather is favorable.
