Painting plastic toys can be a fun activity for both children and adults. However, it can be tricky because plastic is not a porous surface, so the paint has little to stick to. With the right preparation, you can successfully paint plastic toys with a variety of paints, including water-based, non-toxic, and acrylic paints. To ensure the paint adheres well, it is recommended to use a primer specifically designed for plastic and to sand the surface of the toy to create a rougher texture for the paint to grip onto. Additionally, cleaning the toy with mild soap and water before painting can help remove any dirt or residue that may interfere with the paint's adhesion.

Sanding plastic toys
Painting plastic toys can be tricky, but with the right products and preparation, you can achieve a good result. Here is a step-by-step guide to sanding plastic toys before painting them:
Step 1: Wash the Toy
Before sanding, it is important to clean the plastic toy thoroughly. Use a non-scratch sponge or a rag and scrub the toy with soapy water. Rinse the toy with clean water to ensure no soap residue remains. For outdoor toys, ensure there is no dirt or mildew remaining. You may need to wash more than once to thoroughly clean the toy.
Step 2: Sand the Toy
Since most plastic surfaces are smooth and glossy, sanding is necessary to create a rougher surface for the paint to adhere to. Use fine-grit sandpaper or a sanding sponge to gently sand the toy. Fine sandpaper, such as #180 to #100, will create a rougher surface without leaving visible sanding marks. If the toy has curved surfaces or small crevices, sandpaper may be easier to use than a sanding block. Remember to pay extra attention to shiny parts, as these will need a bit more sanding for the paint to stick. Sand the toy until the surface feels slightly rough to the touch.
Step 3: Remove Sanding Dust
Once you have finished sanding, it is important to remove all the sanding dust. Use a dry cloth first to wipe away most of the dust. Then, use a wet rag soaked in mineral spirits or isopropyl alcohol to trap the remaining particles and ensure no dust is left behind. This step is crucial, as any remaining dust will interfere with the paint's adhesion.
Step 4: Prime the Toy
After sanding and cleaning the toy, it is now ready for priming. Lay the toy flat on a tarp, cardboard, or plastic sheet to protect your work area. Spray the toy with thin, even coats of primer, moving in one direction without going back over sprayed areas. Use a plastic-specific primer, such as Rust-Oleum Specialty Plastic Primer, to ensure the best adhesion. Allow the primer to dry completely according to the manufacturer's instructions before proceeding to the next step.
Step 5: Paint the Toy
Now that your toy is sanded and primed, it is ready for painting. Choose a paint that is suitable for plastic and will provide the desired finish. Spray paint is generally recommended for plastic toys, as brush painting tends to leave brush marks. Hold the spray can about 10 inches away from the toy, at a 45-degree angle, and spray lightly, building up thin layers to avoid drips. Allow each coat to dry completely before adding the next one. For most paints, three coats will provide opaque coverage.
Additional Tips:
- Always work in a well-ventilated area when spraying primer and paint.
- If you notice any drips while painting, sand them down and wipe the area with mineral spirits before applying the next coat.
- Once the final coat of paint is completely dry, you can add a clear spray sealant with UV protection to prevent the colour from fading.

Removing dust from sanded toys
Painting plastic toys can be a great way to give them a new lease of life. However, because plastic is a smooth surface, it can be difficult to get paint to stick. The best way to ensure paint adhesion is to sand the plastic with fine-grit sandpaper to roughen the surface. This will give the paint something to stick to. Once you've finished sanding, you'll need to remove the dust created by the sanding process. Here's a step-by-step guide:
- Use a dry cloth: Take a dry, lint-free cloth (such as a microfibre cloth) and wipe down the sanded toy. This will remove the bulk of the dust.
- Wet rag: After removing the majority of the dust, use a wet rag with mineral spirits or isopropyl alcohol to wipe down the toy. This will help trap the remaining fine dust particles.
- Vacuum: If you're concerned about any lingering dust, you can use a vacuum with a brush attachment. This will minimise the chance of scratching the surface. However, be aware that a vacuum may not remove all the very fine dust particles.
- Tack cloth: As an alternative to a wet rag, you can use a glue-soaked cloth (also known as a tack cloth) to remove the remaining dust. These are designed to remove dust from sanded surfaces and can be purchased from hardware stores. However, they may not be reusable, and you may not know what chemicals are used to make them sticky.
Once you've removed the dust, it's important to ensure the toy is completely dry before proceeding with painting. Check the paint can for temperature requirements and choose an area that is well-ventilated if you're using spray paint. Lay down a tarp, plastic sheet, or cardboard to protect your work area, and then you can begin the painting process!

Priming plastic toys
Painting plastic toys can be a great way to give them a new lease of life. However, plastic is one of the more difficult surfaces to paint because of its smooth and non-absorbent surface. As such, it is important to prime the toys before painting to ensure the paint adheres properly. Here is a step-by-step guide to priming plastic toys:
Sand the surface:
Use fine-grit sandpaper to roughen the smooth surface of the plastic toy. This will give the primer and paint something to stick to. Be sure to use a light touch to avoid leaving visible sanding marks.
Clean the surface:
Once the toy has been sanded, use a dry cloth to remove any sanding dust. Then, use a wet rag with mineral spirits or isopropyl alcohol to remove any remaining particles. It is important to ensure the surface is clean so that the primer and paint can properly adhere.
Prepare your work area:
Spray painting is best done outside due to fumes and overspray. Place the toy on a flat surface, such as a tarp or a large piece of cardboard, to protect the surrounding area from paint. If there are areas you do not want to paint, use painter's tape to mask them off.
Apply the primer:
Spray the toy with thin, even coats of primer. Move your arm in one direction, following a close zig-zag pattern, and avoid going backwards over areas you have already sprayed. Allow the primer to dry completely according to the manufacturer's instructions before proceeding to the next step.
Spray paint:
Once the primer is dry, you can begin spray painting the toy with your chosen colour. Again, use thin, even coats of paint and allow each coat to dry completely before applying the next. It is important to be patient and not rush this process, as plastic requires multiple light coats of paint to avoid drips and ensure proper coverage.
Seal and protect:
After the final coat of paint has dried, you may wish to apply a clear spray sealant with UV protection to prevent the colour from fading over time.

Choosing the right paint for plastic toys
Plastic is a tricky surface to paint because, unlike wood, it is not porous, so the paint has little to stick to. With the right amount of preparation, however, you can paint plastic with success.
Firstly, it is important to clean the toy with mild dish soap and warm water to remove any surface dirt. Use a soft cloth or sponge for smooth surfaces. Allow the toy to dry thoroughly.
Next, sand the toy with fine-grit sandpaper. This will rough up the smooth plastic surface and give the paint something to stick to. Be sure to use a fine grit to avoid leaving visible sanding marks. Remove the sanding dust with a dry cloth, and then a wet rag with mineral spirits or isopropyl alcohol.
Now you are ready to apply a coat of primer. Primer will help even out the surface of the plastic and give the paint something to stick to. Spray-on primer will give you a smoother finish, but you can also get brush-on primer. Be sure to cover your work surface and work in a well-ventilated area. Allow the primer to dry completely before proceeding.
Finally, you are ready to paint. You can use spray-on or brush-on paint. Apply a single, light coat, then let it dry for at least 30 minutes. Apply one to two more coats, if needed, allowing 30 minutes between each one.
To protect the toy against paint damage, you can finish with a clear spray coating. This will also make the colours pop. Make sure it has UV protection so that the colour doesn't fade over time.

Sealing painted plastic toys
Painting plastic toys can be a great way to give them a new lease of life. Plastic is a difficult surface to paint due to its smooth and temperature-responsive nature, which makes it prone to cracking or flaking over time. However, with the right preparation and sealing, you can achieve a long-lasting and vibrant finish.
Before painting plastic, it is important to prepare the surface by sanding it with fine-grit sandpaper to create a rougher surface for the paint to adhere to. Once the surface is sanded, remove any dust with a dry cloth, followed by a wet rag with mineral spirits or isopropyl alcohol to ensure there is no barrier between the paint and the toy.
When choosing a paint, opt for a spray paint specifically designed for use on plastic. These paints are formulated to adhere well to plastic surfaces and can often be found with a primer included. If your paint does not include a primer, it is recommended to use a plastic-specific primer first to improve adhesion and ensure a more durable finish.
After painting, allow the paint to dry completely before reassembling the toy if necessary. To seal and protect the paint job, apply a clear spray sealant with UV protection. This will help prevent the colour from fading over time, especially if the toy is intended for outdoor use.
Some recommended products for painting plastic toys include Rust-Oleum 2x and Krylon Fusion, which offers a specific paint for plastics. When using these products, be sure to follow the manufacturer's instructions for the best results.
