If you’re an artist who uses surfaces of plastic as a canvas, you may have experienced the frustration of your acrylic paint not sticking. This problem can lead to wasted time and materials, but it can be avoided.
In this article, I’ll share methods and insights to ensure your acrylic paint bonds flawlessly with plastic, elevating your artistic endeavors.
Acrylic Paints, Explained
Acrylic paint is a fast-drying, water-soluble paint made from pigment suspended in an acrylic polymer emulsion. These are versatile and can be used on various surfaces, including canvas, paper, fabric, wood, and more.
They are water-resistant and lightfast, meaning they won’t fade or turn yellow over time. Unlike oil paints, this paint is dry to a flexible, durable film resistant to cracking and peeling.
Additionally, these can be thinned with water and easily cleaned up with soap and water. This makes them popular among artists and hobbyists, who appreciate the ease of use and quick drying time.
Acrylic Paint Uses
These paints are widely used for various applications due to their versatility, quick-drying time, and durability.
In the fine art world, these are used by artists for painting, drawing, and mixed media artwork, as they offer vibrant colors and the ability to be easily manipulated with water or other mediums.
They are also ideal for mural and signage projects, as they dry quickly and resist fading and weathering. These are also commonly used in the crafting industry, as they can be used for decoupage, scrapbooking, and home décor projects.
In addition, they are often used by hobbyists and students, as they are easy to clean up with soap and water and are relatively inexpensive compared to other types of paint.
These paints offer a range of benefits that make them a popular choice for artists, crafters, and hobbyists alike.
Does Acrylic Paint Adhere to Plastic Well?
When it comes to painting on plastic, the type of plastic and how you prep the surface can greatly influence the paint’s adhesion. Typically, this paint sticks best to plastics that are smooth, clean, and dry.
However, some plastics, such as polyethylene and polypropylene, can be more challenging to paint on because they have a non-porous, slick surface that can cause the paint to bead up and not adhere properly.
In these cases, it may be necessary to use a primer or sand the surface to improve adhesion. To ensure the paint adheres well to plastic, it’s crucial to follow the manufacturer’s instructions and clean and prepare the surface properly before painting.
Primer and Paint Compatibility
When you’re buying paint and primer, it’s crucial to ensure they’re compatible. If you’ve opted for a primer specifically crafted for a certain surface, there’s a good chance it may not gel well with just any paint.
Still, if you’re ever in doubt, there’s a simple way to put those concerns to rest: a compatibility test. This will ascertain the harmony between your chosen products.
Here’s how you can evaluate the compatibility between your paint and primer:
- Choose an appropriate paint testing surface and apply the primer evenly.
- Allow the primer to dry thoroughly before applying the paint.
- To assess the adhesion of the primer and paint, make a distinct scratch on the surface using a sharp implement.
- Then, cover the scratch with tape and remove it. If the paint remains intact and adheres to the surface, you can now rest assured that the primer and paint have been applied successfully.
Conversely, if the paint peels away, it indicates that the primer and paint have not appropriately adhered to the surface.
List of Plastic Materials You Can Paint with Acrylic

- Clean the pots: Begin painting by cleaning the flower pots with soap and water to remove any dirt, dust, or oils. Let them dry thoroughly.
- Sand the surface: Sand the surface of the pots lightly to create a surface that the paint can adhere to. Use fine-grit sandpaper and sand in the direction of the plastic's grain.
- Apply a primer: To ensure that the paint adheres to the plastic, apply a plastic primer. This will also help to create a smooth surface for painting. Let the primer dry before continuing.
- Paint the pots: Once the primer is dry, it's time to start painting. Use a paintbrush or spray paints to apply the paint. Choose a color that matches your decor or garden. Apply at least two coats of paint, allowing each coat to dry thoroughly before applying the next one.
- Seal acrylic paint: To protect the paint and make it more durable, apply a clear sealant. This will also make the pots water-resistant. Let the sealant dry completely before using the pots.

How to Properly Apply Acrylic Paint on Plastic Surfaces
Necessary Materials
Here is the list of materials you will need:
- Newspapers for protection and cleanup.
- Tack cloth
- Scrub brush
- Painters tape
- Paint brushes (if using liquid acrylic or enamel paints)
- Spray cans, liquid paint, or enamel paint
- Isopropyl alcohol
- Soap and water for cleaning
- Fine sandpaper
- Clean clothes for painting
- Adhesive tape for masking
- Surface preparation product (primer)
- Transparent sealing material (sealer)
- A plastic object
Step #1: Prepare the Surface
Before you start painting plastic with acrylic, make sure you have all the things you need to keep yourself safe and protected. You should wear clothes that you don’t mind getting paint on and make sure you have a cloth or newspaper to keep your working area clean.
Go to a place with fresh air or open a window to make sure the paint doesn’t make you feel sick. Some paints have bad stuff, like xylene [1], toluene, methyl ethyl ketone, and turpentine, that can make you sick if you breathe it in.
If this happens, you can use a fan or a special mask to keep you safe.
Take your sandpaper and gently rub the shiny surfaces of the thing you want to paint. Don’t rub too hard, or you might scratch it. Plastic is a special type of material that doesn’t soak up paint, so rubbing it will help the acrylic paint stick to the plastic better.
After you are done sanding, wipe the surface with a soft cloth to get rid of any dust. If you want it to be extra clean, you can wash it with soap and water.
Use rubbing alcohol or special cleaning to remove any oils, fingerprints, or dirt on the surface. This will also help the acrylic paint stick better.
Use masking tape to cover up the parts of the item that you don’t want to paint. This will help you paint a clean line and ensure you only paint the parts you want.
Step #2: Add the Primer
Before painting plastic with acrylic, it is vital to make sure it is ready. If the plastic is shiny, you should first put a clear, glossy coating on it to help the acrylic paint stay. You can use a special spray or liquid primer made of plastic.
Make sure to put a thin layer of primer all over the plastic and let it dry before moving on to the next step.
Step #3: Start Painting the Plastic Surface
When you are ready to paint your plastic item, it is crucial to start by placing masking tape around the area you want to paint.
This will help ensure that the paint does not go where you don’t want it to. Then, make sure to choose the right paint for plastic by checking for the label that says “for plastic.”
Once you have the right paint, you may need to prepare it. This could mean just using it straight from the container or mixing it with a thinner. Before you start painting, check the instructions on the paint label.
To achieve a smooth, polished look, you should thin your paint with either paint thinner or water. Then, apply a light coat of paint using a roller, brush, or spray paint. If you are using acrylic spray paint, hold the nozzle about an inch away from the surface and apply several light coats.
Patience is key when painting. Wait a minimum of two hours before layering on another coat. If your paint specifies a post-drying period, resist the urge to touch the item for at least four hours.
Continue adding coats until you achieve your desired appearance, ensuring each layer dries fully before proceeding with the next.
Step #4: Seal the surface
To protect the plastic’s painted surface, it’s essential to use a sealer. Acrylic paint is known for being durable, but it can become chipped or scratched from frequent use over time.
I recommend using glaze or varnish to keep your painted item in good condition. This will help to protect it and make it last longer.
You can either apply the acrylic sealer with a brush or spray it on. Choose the type of sealer you want to use – it can be matte, satin, or glossy. Start by putting on a light coat and letting it dry for about 30 minutes.
I suggest applying several thin coats of sealer instead of one thick coat because the sealer can become sticky if it’s too thick.
Step #5: Allow it to Dry Completely
To make your painted plastic item look more interesting and special, add some extra touches before the paint dries. For example, you can use a paint marker or special paints to create details, characters, or life.
You can use sandpaper to add some texture if you prefer a more rugged look. Remember, there’s no right or wrong way to paint your plastic item as long as you like the result. Have fun and be creative!
Once you’ve finished applying clear acrylic sealers to your item, wait for it to dry thoroughly, following the instructions on the bottle. Don’t touch it until it’s completely dry, and then your work is done.
Acrylic Spray Painting on Plastic in 4 Steps
Acrylic painting on plastic with regular spray paint can be a quick and effortless option. With some spray paints, you don’t have to prepare the surface by using a primer or sealing the paint.
Additionally, the drying process is often quicker with spray paint than with traditional liquid paint, making the overall experience more convenient.
Here are the steps to use acrylic spray painting on plastic materials:
Step #1: Ready the Surface
Before you start painting acrylic, it’s essential to properly prepare the surface of the plastic by cleaning, sanding, and priming it. Also, be sure to read the label on your paint for plastic.
Some spray paints require you to shake the can beforehand and between each clear coat of paint. The label will also indicate if using a primer and sealer is necessary for conjunction with the spray paint.
Step #2: Apply Primer
If you use traditional spray paint instead of one specifically designed for plastic, it is crucial to apply a primer beforehand. There are numerous plastic-specific spray primers available on the market.
Follow the instructions on your chosen primer bottle to ensure optimal results. Let the primer dry thoroughly before proceeding with the painting process.
Step #3: Start Spraying the Paint
Before starting the actual painting process, it’s a good idea to test the spray paint on a scrap piece of newspaper, cardboard, or drop cloth to check for the desired color and consistency.
When applying the spray paint, aim the nozzle toward the plastic and apply a thin, light layer. Hold the spray can from a distance of around 8 to 12 inches away from the surface of the plastic.
Allow the paint to dry, then apply the next layer. Again, I’d recommend applying several thin coats rather than a single thick one. When spraying, maintain a distance of about 12 inches and give the object a light mist.
The first coat may not fully cover the object, but applying the first layer too quickly may result in drips. If you have any dried drips, you can sand the surface flat before adding the next coat.
If the plastic still doesn’t look fully saturated after the paint has dried for two hours, you can add a third and final coat.
Step #4: Leave the Surface to Dry
After completing the painting process, let the spray paint dry thoroughly before using the object. I highly recommend placing the object in a warm and dry place for at least two hours to ensure full drying.
Tips for Painting Plastic
Here are a few tips to help ensure a successful outcome.
Use Painter’s Tape to Maintain Clear Lines
Make sure to use high-quality painter’s tape to ensure a clean and precise paint job. Although it may cost more, it will provide better results than lower-quality tape.
The tape will serve as a barrier and protect the areas of the product that you don’t want to be painted. To further cover the unwanted areas, you can attach a piece of newspaper or a paper bag to the surface.
Strip the Tape Immediately After Usage
I also recommend removing the painter’s tape before the paint can dry thoroughly. This is because if the tape is left on for too long, it can peel off the fresh paint, ruining the surface.
To prevent this, it is best to only apply one coat of primer before moving on to the painting process.
Use Sandpaper or Sander Alternatives
If you want to ensure a good bond between your paint and the surface of the plastic, consider using a liquid sander instead of traditional sandpaper. These products can be found at home improvement stores, and some can even be painted over in just 10 minutes.
Slight alterations like painting can increase the perceived value of an item, saving you money instead of having to buy new products.
Painting plastic items can give them a brand-new appearance and even make them look better than they did originally. Changing the color or adding designs to a room can make it feel more lively and welcoming.
Use Primer Alternatives
If you don’t have a particular type of paint called a primer, you can use enamels or oil-based paint as a base coat before using acrylic paint on plastic. However, using a primer specifically designed for plastic will give better results.
Inspect your storage for Materials You’re Not Using
Looking for ways to save money? Why not start by giving new life to old plastic items you no longer use or that have lost their shine? With a bit of effort and paint, these items can be transformed and restored to their former glory without spending much money on new ones.
How You Can Make Acrylic Paints Stay on Plastic Surfaces
To ensure that acrylic paint sticks on plastic, it is important to prepare the surface properly. This includes cleaning, sanding, and priming. To finish the job, you should seal the surface with a waterproof layer for added durability.
One of the main reasons why acrylic paint may peel away from plastic is contamination. Start by cleaning the plastic surface with mild soap and warm water. For objects that are heavily soiled or greasy, use a cleaner or degreaser specifically designed to remove these substances.
You can choose from various options, such as those with low levels of volatile organic compounds or pure solvents. Roughing up the surface of the plastic can also make it easier to paint, and sanding the surface helps the paint bond more effectively.
This also removes any oxides or films that may be present, which will increase the chance of successful adhesion. Use fine-grain sandpaper, and clean off any loose particles before painting. Moreover, when priming plastic, you can either use a brush or spray.
Just be sure to choose a primer that is specifically designed for the surface you are working with. The drying time and the number of coats required will depend on the type of primer being used. Most primers are applied in a thin base coat to secure the paint to the entire surface.
Sealing Acrylic Paint on Plastic Surfaces
Sealing your plastic surface right after you’ve painted it with acrylics is important. This is because water can affect acrylic paint, and the colors can quickly spread if not protected from moisture.
Since surfaces of plastics are touched frequently, it’s important to secure the paint so that it lasts a long time. Sealing the surface also makes it resistant to water.
There are effective methods for sealing plastic with acrylic paint that I have tried and tested. These five methods are highly recommended for anyone looking to protect their painted plastic surface:
Applying Polyurethane for Longevity
When it comes to protecting your painted plastic surface, polyurethane is a more durable option compared to polycrylic. However, it’s important to note that water-based polyurethane tends to turn yellow after drying and can change the desired color of your project.
But if you still prefer poly, here are our recommendations for the best non-yellowing polyurethanes!
It can also be applied in the same manner as a polycrylic roll-on. Polyurethane is ideal for big projects such as toy cars, figurines, outdoor or indoor furniture, flowerpots, and more, as it is self-leveling.
Applying Polycrylic for a Clear Finish
The primary purpose of polycrylic is to provide a protective barrier for painted surfaces of plastic, making it ideal for indoor projects. It’s available in different finishes, including matte, semi-gloss, high gloss, and ultra-flat.
To use polycrylic on your plastic surface, apply an even coat of the spray solution. You can add multiple thin layers and wait for each one to dry for 2 hours before applying the next. It’s recommended to apply 2 to 3 coats in total to complete the project.
While it’s not as durable as polyurethane, one of its advantages is that it doesn’t yellow over time and dries quickly.
Applying Acrylic polymer for Outdoor Furniture and Paintings
To protect your plastic furniture and surfaces from discoloration, consider using acrylic polymer varnishes, which come in a range of finishes such as gloss, satin, and matte.
If you are a skilled painter, DIYer, artist, or crafter, you may opt for the satin finish, a combination of both gloss and matte. These varnishes are designed with UV protection in mind, helping to maintain the original color of your plastic surface.
Using Acrylic Resin for Detailed Crafts and Arts
Acrylic resin varnish is a strong and durable finish. It is ideal for small projects like costume jewelry and beads that require a robust protective surface. Once applied in a thick layer, the final result will have a bright, glossy luster appearance with no added color.
Using Mod Podge for a Glossy Finish
For a smooth and glossy finish, consider using a mod podge on your plastic surface. This medium-strength, clear permanent glue can be used as a topcoat for paint. It’s a good choice if you want a glossy coating for your project.
Are There Sanitizers and Cleaners That Can Help in Painting?
Yes, several sanitizers and cleaners can help with painting projects. Here are a few examples:
Solvent cleaners
Solvent cleaners, such as mineral spirits or denatured rubbing alcohol, are commonly used to clean brushes, rollers, and other painting tools. They can also clean surfaces before acrylic painting to remove dirt, grease, and other contaminants.
TSP (Trisodium Phosphate)
TSP is a heavy-duty cleaner used to clean surfaces before acrylic painting. It is particularly effective at removing grease and oil stains, making it a good choice for kitchen and bathroom surfaces.
Water-based cleaners
Water-based cleaners, such as white vinegar or dish soap, can also clean surfaces. They are less harsh than solvent cleaners and are a good choice for cleaning delicate surfaces or if you are looking for an environmentally-friendly option.
Disinfectant sprays
After the surfaces have been cleaned and before painting, you can use a disinfectant spray to sanitize the area. This is particularly important in areas with a high risk of contamination, such as bathrooms, kitchens, and hospitals.
It is important to follow the instructions on the label of the sanitizer or cleaner you choose to ensure that it is used safely and effectively.
