Clean the doll's surface with soap and water
To spray paint plastic doll toys, it is important to clean the dolls' surfaces with soap and water to ensure the paint adheres properly. Here is a step-by-step guide to doing this:
Firstly, fill a sink or a bowl with warm water and add some liquid dish soap. Stir the water and soap mixture until suds form, creating a soapy solution. Then, soak a non-scratch sponge or a microfiber cloth in this solution. It is important to use a non-abrasive material to avoid scratching the plastic surface.
Next, scrub the doll's surface gently with the soapy sponge or cloth. Ensure you cover all areas of the doll, including any crevices or detailed areas. This step will remove any dirt, dust, or grime that may be present on the doll, providing a clean base for the paint.
After scrubbing, rinse the doll with clean water to remove any soap residue. You can use a gentle stream of water from a hose or a spray bottle for this step. Ensure that all soap residue is removed, as it could affect the paint adhesion if left on the surface.
Once the doll is thoroughly rinsed, dry it completely before moving on to the next step. You can use a microfiber cloth or a towel to gently pat down the doll, absorbing any excess water. Ensure that the doll is completely dry to the touch before proceeding with the spray painting process.
By following these steps, you will effectively clean the plastic doll toys with soap and water, preparing them for a smooth and even spray paint application. This process will help ensure that the paint adheres properly to the surface, resulting in a professional-looking finish.

Use a plastic primer
To spray paint plastic doll toys, it is important to use a plastic primer to ensure the paint adheres to the plastic surface and to prevent the paint from peeling or chipping. Firstly, prepare your workspace by laying out some cardboard or a drop cloth to protect the surrounding area from paint. You can also create a single-use spray booth with a cardboard box for added protection. It is also a good idea to wear a painting mask.
Next, clean the plastic surface of the doll toy with a damp rag or a sanitizing cleaner to remove any dirt, grime, or mould. If the doll toy is brand new, you can wipe it down with mineral spirits or rubbing alcohol to break down any sealants. Once the toy is clean, allow it to dry completely.
After the doll toy is dry, use a fine-grit sanding block to lightly sand the surface to a dull finish. This will create some texture so that the primer will stick better. Then, use a dry brush or a large paintbrush to dust away any debris and wipe the surface with a wet cloth. Let the doll toy dry completely.
Now, you can apply the plastic primer. Shake the can for about a minute, until you hear the metal mixing ball inside. Then, apply the primer using thin layers, following the directions on the back of the can. For example, Rust-Oleum recommends applying one thin coat, rather than a heavy coat or multiple coats, shaking the can as you spray. After applying the primer, the surface will be ready to be painted within 10 minutes. Don't forget to invert the aerosol and spray for several seconds once you're done.
Using a plastic primer will help ensure that the paint adheres well to the plastic surface of the doll toy and will prevent the paint from peeling or chipping over time.

Lightly sand the plastic to add texture
When spray painting plastic doll toys, it is important to lightly sand the plastic to add texture and ensure the paint adheres well. Sanding the plastic will help the paint stick better and improve its ability to adhere to the surface. It is recommended to use a high-grit sandpaper, as a lower grit can cause scratches and gouges in the plastic. The ideal grit range is between 600 and 800, with some sources recommending starting at 400 and increasing the grit progressively without going back to bare plastic. This process will help create a smooth surface for the paint to adhere to and improve the final finish.
It is important to keep the sandpaper moist by spraying water on it or using fresh sandpaper to prevent scratching the plastic. This is because plastic is a relatively brittle substance that is easily scratched, and inadequate usage of sanding paper can result in scratches. By sanding the plastic, you are creating a slightly rougher surface for the paint to grip onto, which will help the paint last longer and reduce the likelihood of chipping or fading.
When preparing plastic for spray painting, it is crucial to start with a clean surface. This can be achieved by washing the plastic with soap and water and ensuring it is thoroughly dry before moving on to the sanding process. Once the plastic is clean and dry, you can begin lightly sanding it in preparation for painting.
After sanding, it is important to choose the right type of paint. Some sources recommend using a primer before applying the colour coat to improve adhesion and reduce the likelihood of paint chipping. However, others suggest that sanding alone will not make the paint stick and that a good primer is still necessary. Therefore, it is essential to select a suitable primer and paint designed for use on plastic surfaces, such as Krylon Fusion for Plastic.
By following these steps and lightly sanding the plastic to add texture, you can achieve a smooth and professional-looking finish on your spray-painted plastic doll toys. This process will help ensure that the paint adheres well and lasts longer, reducing the need for frequent touch-ups.

Use a classic spray-painting technique
Spray painting plastic doll toys is a fun and easy way to give them a new look. It can be a great way to save money and extend the life of toys that would otherwise be discarded due to fading or chipping paint.
First, ensure the doll is clean by giving it a good scrub with soap and water. This will help the paint adhere better to the surface. Once the doll is dry, use masking tape to cover any areas you don't want to be painted, such as the eyes or specific details. If there are larger areas you want to protect, you can cover them with plastic bags and then use tape to secure the bags in place. This process can be slow and tedious, especially around curved areas, but it will be worth it when you're done.
Now you're ready to start spray painting! Hold the can about 6-8 inches away from the doll and spray in sweeping motions with a bit of overlap. Apply thin coats and let each one dry for a little bit before applying the next. Keep moving around the doll, ensuring you hit the surface from multiple angles. This technique will help you achieve an even finish.
The paint will dry to the touch in about 15 minutes, but it won't be fully chip-resistant until a week has passed. During this time, be sure to store the doll in a safe place, away from extreme temperatures, sunlight, or snow, as these conditions can cause wear and tear on the paint job.
With these classic spray-painting techniques, you can give your plastic doll toys a fresh new look that will be ready for some new adventures!

Finish with a UV spray
When spray painting plastic doll toys, it is important to consider the impact of UV light on the paint and plastic. UV light can cause plastics to break down and discolour over time, especially when exposed to sunlight. This process is called photodegradation and can cause the plastic to release toxins. Therefore, it is recommended to finish spray-painted plastic toys with a UV spray to protect them from UV light and prolong their lifespan.
There are several products available that can be used as a UV spray for plastic doll toys. One option is to use a clear UV-resistant spray paint, such as Krylon UV Resistant Spray Paint in Clear. This will provide a protective layer over the paint and help to prevent UV light from damaging the plastic. It is important to follow the instructions on the spray paint can and take the necessary precautions when working with spray paint, such as working in a well-ventilated area and wearing a mask.
Another option for a UV spray is to use a varnish, such as Tamiya Flat Clear Spray or Krylon Matte Finish. These products can provide a protective layer over the paint, similar to a clear coat. It is important to apply thin and even coats of varnish, as applying it too thickly or in humid conditions can create a cloudy surface. Allow each layer to dry before applying the next coat for the best results.
Additionally, when using spray paint on plastic, it is recommended to use a primer to aid in bonding the paint to the plastic surface. A bonding primer with fusion technology can help improve adhesion and create a premium finish. It is also important to clean the plastic surface before painting to remove any dirt, grease, or debris that could disrupt the paint job.
By following these steps and finishing with a UV spray, you can effectively spray paint plastic doll toys and protect them from the damaging effects of UV light. This will help to prolong the lifespan of the toys and maintain their appearance over time.
