Painting plastic opens a world of creative possibilities. As you unleash your inner Michelangelo, you’re also doing a good deed — like keeping that old, faded plastic lawn furniture out of the landfill.
Fresh paint can revive old patio furniture, upgrade home decor, or add a personality to the models on your shelf.
The trouble is that plastic is less receptive to paint than wood, metal, and many other materials. Your project may become a sticky, peeling mess without proper preparation and technique.
This blog will guide you through the steps of painting plastic like a pro to ensure your project turns out the way you envisioned it.
Everyday Plastic Items That May Need Painting
Outdoor Furniture
After years of exposure to the elements, plastic chairs, tables, and other outdoor furniture can look faded, chalky, and even cracked. A fresh coat of outdoor paint can make them look new or even better than new.

Home Decor
Many home decor items, from picture frames to decorative objects, are made from plastic. Paint can personalize them and better match them to your home’s interior.
Toys & Models
Painting plastic toys and models is an art form for hobbyists and collectors. Whether adding intricate details to a model car or giving a beloved action figure a one-of-a-kind expression, specialized paints allow for professional results.
Kitchenware
Painting old bowls and storage containers can refresh their appeal and adapt them to your kitchen’s aesthetics. Use non-toxic, food-safe paint for surfaces that come into contact with edibles.
Planters
A fresh coat of paint can restore an old pot or planter and provide a protective layer against future wear. Choosing colors that complement your plants and decor helps elevate your container garden to new heights.
You can paint virtually any garden pot, including plastic pots.
Types of Plastic to Consider
- Polyethylene (PE) is durable and weather-resistant. It’s a nonporous material frequently used for outdoor furniture and planters and is challenging to paint without proper surface preparation.
- Polypropylene (PP) often occurs in kitchenware and home decor. Like polyethylene, it’s chemically resistant and smooth. Choose paint products designed to bond with it.
- Polyvinyl chloride (PVC) comes in various forms, from pipes to figurines. It’s less durable than PP or PE, but PVC is lightweight, easy to shape, and somewhat resistant to chemical exposure.
- Polystyrene (PS) is commonly used for toys and models. It’s more delicate than other plastics and needs specific primers and paints.
- Acrylic plastics encompass many plastic materials and are often used instead of glass. They can be difficult to paint without proper surface preparation.
Types of Paint for Plastic
- Acrylic paint works well on all types of plastics. It dries quickly and requires no sealant, making it the go-to choice for many DIY projects.
- Enamel paint bonds well with plastic surfaces but may take longer to dry than acrylic. Some enamel paints require a primer before application.
- Spray Paint offers fast coverage and smooth finishes, making it popular for larger projects like furniture and outdoor decor.
- Latex paint can work on plastic but may not bond as well as other types of paint and may require a primer or sealant.
- Oil-based paint is durable and resistant to wear, making it suitable for high-traffic objects like toys and models. Painting requires good ventilation due to fumes.

Choosing the Right Paint
Different types of plastic require different types of paint, so do some research before starting.
When choosing paint, consider the following factors:
- Adhesion: The ability of the paint to bond with the plastic surface.
- Durability: How well the paint can withstand wear and tear.
- Drying time: This is how long it takes for the paint to dry completely.
- Application method: Choose a paint that works well with your application approach: brush, spray gun, or other tools.
Preparing Plastic Surfaces for Painting
- Clean the surface thoroughly with warm, soapy water and a cloth or sponge to remove any dirt, dust, or residue that may reduce adhesion.
- Rinse the surface with clean water and allow it to dry completely.
- Sand the surface gently with fine-grit sandpaper to create a rough texture for better paint adhesion. Wipe away any dust or debris.
- Apply a plastic primer if necessary, especially for smooth and nonporous plastics like PE or PP. The primer improves paint adhesion and durability.
- Allow the primer to dry completely before moving on to painting. Lightly sand the surface again if necessary.

Painting Plastic Like a Pro
- Choose a well-ventilated area for painting. Fumes from some types of paint can be harmful.
- Begin by painting a small, inconspicuous area to test adhesion and color match.
- Apply thin coats of paint instead of one thick coat to prevent drips and ensure even coverage.
- If using spray paint, hold the can about 6–8 inches away from the surface and use a sweeping motion for even coverage.
- Allow each coat of paint to dry completely before applying additional coats.
- Use fine-tipped or artist’s brushes for detailed projects for precision and control.
Finishing Touches
- A clear sealant can protect against wear and tear and give your project a glossy finish.
- Use stencils or painter’s tape to create intricate designs on your painted plastic surface.
- Consider adding a layer of varnish for added durability and shine.

FAQs: Painting Plastic
Q: Can I use any paint on plastic?
Not all paints are suitable for plastic. Use paints formulated for plastic surfaces. These contain additives that enhance adhesion and are available in spray and brush-on varieties.
How long does painted plastic last?
It can last for several years. Outdoor items may need more frequent touch-ups due to exposure, while indoor items generally maintain their appearance longer.
What should I do if the paint chips?
Lightly sand the affected area and clean it thoroughly. Apply a primer to the exposed plastic, followed by the paint. Finish with a sealant to blend the repair with the rest of the surface.
Q: Should I use a primer before painting plastic?
We recommend applying a primer for smooth and nonporous plastics like polyethylene (PE) or polypropylene (PP) to enhance paint adhesion and longevity.
Q: Is acrylic paint suitable for outdoor plastic items?
Yes, but it requires a clear sealant to withstand the elements. The sealant adds a layer of protection against UV rays and moisture.
Q: Can paint be removed from plastic if I make a mistake?
Yes. The method depends on the paint type and duration. For fresh paint, use a damp cloth or mild soapy water. For dried paint, try a plastic-safe solvent or isopropyl alcohol. Test a small area first.
Q: What’s the ideal temperature for painting plastic?
The ideal temperature range for painting plastic is between 50°F and 90°F (10°C to 32°C) in low-humidity conditions. Extremes in temperature or high humidity can affect drying times and adhesion, leading to less satisfactory results.
Q: How can I prevent paint from peeling off plastic over time?
Ensure thorough preparation, including cleaning, sanding, and priming. Apply paint in thin, even layers and finish with a clear sealant to enhance durability.
