When it comes to painting plastic, there is a wide range of spray paints available that will adhere well. Depending on the desired finish and application, you may choose either a multi-surface or a plastic specific spray paint.
For a non-glossy finish, a multi-surface paint such as Krylon ColorMaster Paint & Primer is a great option as it is designed to bond to hard-to-coat surfaces like plastic, wood, metal, and more. Simply clean the plastic surface with a degreaser and then lightly sand it with fine grit paper before applying the paint.
If you’re looking for a glossy finish, a plastic-specific spray paint is the way to go. These paints have superior adhesion and flexibility to assure that the finish won’t crack over time. Krylon Fusion for Plastic is a great option and can be used with plastic, PVC, Fiberglass and Resin.
Just make sure to clean the surface of the plastic before painting and you’re ready to go.
What is the paint to adhere to plastic?
When looking for a paint to adhere to plastic, there are many different products on the market. Depending on your application and the type of plastic, different paints may be better suited to the task.
Generally, high-quality 100% acrylic latex paints are the best choice. For exterior applications, make sure the paint has high levels of UV protection and water resistance. If the plastic is a hard type such as polycarbonate, PMMA, PVC, or polystyrene, you should use specialty paints that have been formulated to adhere to these materials.
These paints typically use air-dry systems, so they may require a primer first to maximize adhesion. If you’re working with a soft plastic such as polyethylene or polypropylene, a specialty adhesive primer may be necessary to establish a strong bond between the plastic and the paint.
After preparing the surface for painting, you should make sure to apply multiple thin layers of paint for the best results. Allow each layer to dry before applying another one.
Do you need to prime plastic before painting?
Yes, it is generally recommended to prime plastic before painting it. Primer creates a better surface for the paint to stick to, so it is important for achieving an even finish. It will also help the paint adhere better and last longer.
When choosing a primer, use one that is designed specifically for the type of plastic you plan to paint, such as for vinyl, acrylic, or polycarbonate. The instructions for the product should include the recommended application method, but usually the primer should be lightly sanded before painting.
It is important to follow the instructions and safety precautions carefully, such as to use protective clothing and a well-ventilated work area. After the primer has been applied and dried, the surface should be sanded down again to ensure an even base.
Once this is done, you are ready to begin painting the plastic.
How do you keep acrylic paint from peeling off plastic?
The key to keeping acrylic paint from peeling off plastic is to ensure that the object is properly prepped before painting. This includes cleaning the plastic surface using a mild detergent and warm water, then wiping it dry and sanding it with a 120 to 100 grit sandpaper.
Once the plastic surface is clean and rough, use a primer specifically designed for plastic and apply a thin, even coat. Allow it to dry completely before applying the acrylic paint. You can also increase adhesion by adding an appropriate proportion of a medium, such as an acrylic glazing liquid, to the paint.
Finally, a final sealant, such as a clear coat lacquer, should be applied after the acrylic paint has thoroughly dried. This sealant will create a layer that will protect the paint from peeling off.
Does acrylic paint stay on plastic?
Yes, acrylic paint will stay on plastic. When painting with acrylics on plastic surfaces, it is important to properly prepare the plastic surface so that the paint will adhere correctly. To do this, you’ll want to use a fine-grit sandpaper to lightly scuff the surface, then wipe away any residue with a damp cloth.
Once the surface is prepared, you can now paint it with acrylic paint. Acrylic is an adaptable product that makes adhesion to most surfaces relatively easy. Be sure to use multiple coats to ensure the best finish.
Allow each layer at least an hour of drying time before applying additional coats. After the desired number of layers have been applied and completely dried, the plastic surface should now be properly sealed with a clear coat, such as a polyurethane sealant.
This will ensure maximum longevity of the acrylic paint on plastic surfaces.

Whether you are looking to update outdoor furniture or spruce up a planter, Krylon spray paint is a great choice for plastic surfaces.
How long does Krylon Short Cuts take to dry?
Krylon Short Cuts takes approximately 15 minutes to dry to the touch, but it takes 24 hours for the paint to cure and reach its full adhesion and durability. If you plan on using the painted item soon, it’s best to allow it to cure for the full 24 hours before handling it.
Even after 24 hours, though, it’s best to use light handling for the painted item for at least a week to ensure that the paint has fully cured.
Can I spray paint plastic without primer?
Yes, you can spray paint plastic without using a primer. However, it’s always important to carefully prepare the plastic before you begin painting. Start by cleaning the plastic with a mild detergent solution and a soft cloth.
Remove any dirt, dust, or other debris before proceeding. Once the plastic is clean and dry, lightly sand the surface with 300 to 400 grit sandpaper. This will allow the paint to adhere better. After sanding, use a damp cloth to remove any dust and cleaning any remaining dust.
Now you can spray paint the plastic and you won’t need to use primer. However, keep in mind that final results may vary depending on the type of paint you are using. To make sure you achieve the best results, always check the manufacturer’s instructions before starting.
What paint sticks to plastic not spray paint?
When painting on plastic, the type of paint you use is incredibly important. You can’t just use any type of paint and expect it to stick well – especially not spray paint. Instead, look for a specially formulated paint like a plastic paint, which is designed to adhere to plastic surfaces like plastic toys, vinyl furniture, and outdoor plastic furniture.
Other types of paint that can adhere to plastic include enamels, acrylics, and epoxies. When selecting a paint, make sure that it specifically states that it can be used on plastic surfaces. Some enamels, for example, contain solvents that can damage the plastic and should not be used.
Before you paint, be sure to prep the surface by thoroughly cleaning the plastic and filling any scratches with a filler material designed for plastic. Once the surface is clean and prepped, use a foam brush, bristle brush, or roller to apply the paint carefully and evenly.
Allow proper drying time according to the manufacturer’s instructions before using the newly painted plastic item.
