What You'll Learn
Choosing the right paint
Firstly, it is important to determine the type of material your helmet is made of. Most dirt bike helmets are made of thermoplastic or fibreglass. Look for the ASTM sticker to identify your helmet's material. This sticker will be located on the back or bottom of the helmet.
If your helmet is made of thermoplastic, you can use any paint designed for plastic surfaces. Acrylic paint, designed for use on plastics, is recommended and can be found at most hardware stores.
On the other hand, if your helmet is made of fibreglass, you will need to use paint specifically made for that material. Regular enamel or lacquer paints are not suitable for plastic helmets as they will not bond well.
Before painting, it is crucial to clean the helmet thoroughly to ensure the paint adheres properly. Use a mixture of dish detergent and water, and wipe down the helmet's surface with a rag to remove any dirt, grease, or grime. If you are painting over an existing paint job, sand the surface lightly with fine-grit sandpaper to provide a good base for the new paint to adhere to. However, be careful not to sand too deeply, as this can weaken the outer shell of the helmet.
Additionally, consider using a primer made specifically for plastic surfaces. A primer will help the paint adhere better and give a more even finish. Apply a thin layer of primer and let it dry completely before painting.
When painting, use thin layers of paint rather than one thick coat to prevent runs and sagging. Allow each layer to dry completely before applying the next. Finally, once you are happy with the paint job, apply a clear coat specifically made for plastic surfaces to protect the paint and give it a glossy finish.

Preparing the helmet
Firstly, it is important to select the right type of paint for your helmet. Helmets are made of different materials, so choosing a paint suitable for the specific material of your helmet is essential. If your helmet is made of plastic, opt for acrylic paint designed for plastic surfaces. You can usually find this type of paint at hardware stores. In addition to the paint, gather other supplies, including painter's tape, newspaper, and fine-grit sandpaper.
Before painting, ensure you are working in a well-ventilated area and wear proper respiratory protection, especially when using spray paint. Now, it's time to prepare the helmet surface. Start by removing any removable fittings or parts you don't want to paint, such as a visor or face mask. Use masking tape to cover any remaining areas you want to protect from paint, such as the inner shell and vents. Make sure only the areas you want to paint are exposed.
Next, clean the helmet thoroughly to ensure the paint will adhere properly. Use a mixture of dish detergent and water, or a grease remover, to wipe down the helmet's surface. Remember to wear gloves to avoid leaving fingerprints on the helmet. Once the helmet is clean and dry, use sandpaper to roughen the surface, creating a better base for the paint to adhere to. Wet sandpaper can be used, followed by wiping the helmet with a wet rag to remove any particles.
Now, it's time to sketch your design onto the helmet. You can use a pencil to draw your design freehand or use stencils, stickers, or tape to create more intricate details. Take your time with this step to ensure your design turns out as envisioned. Once your design is ready, you may want to consider applying a thin layer of primer first, especially if you are painting over an existing coat of paint. The primer will help the paint adhere better and give you a more even finish. Choose a primer made specifically for plastic surfaces and let it dry completely before painting.
With these preparatory steps completed, you are now ready to start painting your plastic helmet.

Applying the paint
When it comes to applying the paint, there are a few methods you can use. Firstly, ensure you have selected a paint that is safe for use on plastic helmets. You can use paint markers for intricate details, or spray paint to cover more surface area. If your helmet is made of fiberglass, be sure to use paint specifically designed for that material.
Before you begin, cover or remove any parts of the helmet you do not want to be painted. Use masking tape, paper, or plastic to shield these areas. If your helmet has removable fittings, such as a visor or face mask, simply detach them. If you are using spray paint, be sure to work in a well-ventilated area and wear proper respiratory protection.
Now, you can start priming the helmet. Primer will help the paint adhere better and create a more even finish. Apply a thin layer of primer over the entire area you plan to paint, and let it dry completely.
Next, apply your paint. Start by applying a thin layer of paint over the entire area, and let it dry before applying another coat. Repeat this process until you are happy with the coverage. Remember to be patient and take your time between coats.
Once you are satisfied with the paint job, you can finish by applying a clear coat to protect it and give it a glossy finish. Again, ensure you are using a clear coat designed for use on plastic surfaces. Apply a thin layer of clear coat over the painted area, let it dry for 15-20 minutes, and then repeat this process 2-3 more times for an even finish.

Adding a clear coat
Firstly, it is important to choose the right type of clear coat. Select a clear coat that is specifically designed for use on plastic surfaces. Check the ingredients of the clear coat to ensure it is safe for your helmet. Some clear coats may eat away at the foam inside the helmet, so always double-check before spraying. It is recommended to use a Urethane clear coat for your plastic helmet.
Next, prepare the helmet by covering or removing any parts you do not want to be clear-coated. This includes removable fittings such as a visor or face mask. Use masking tape to cover any parts that cannot be removed, like the inner shell and vents. Make sure only the area you want to clear coat is exposed. Additionally, sketch your design on the helmet with a pencil, or use stencils, stickers, or tape to create your desired pattern.
Now, you are ready to apply the clear coat. Ensure that the paint is completely dry before applying the clear coat. Use a thin layer of clear coat and apply it over the entire painted area. Allow the clear coat to dry for 15-20 minutes, and then repeat the process 2-3 times to ensure an even coating and maximum protection for your paint job. It is usually suggested to apply four layers of clear coat for the best results.
Finally, let the clear coat sit overnight before reattaching any of the fittings you removed. Now, your plastic helmet has a glossy finish and your paint job is protected!

Legal considerations
Painting a plastic helmet comes with several legal considerations. Firstly, it is crucial to check local laws and regulations to ensure that painting your helmet is legal in your jurisdiction. In some places, altering the appearance of a helmet, especially a motorcycle helmet, may violate road safety laws. For example, in Queensland, Australia, painting a helmet is considered non-compliant with AS 1698, the Australian Standard for protective helmets for vehicle users. This can result in fines for the helmet user.
To ensure legality, it is imperative to select the appropriate paint for your plastic helmet. The paint you choose should be specifically designed for use on plastic surfaces. Using regular enamel or lacquer paints is not advisable, as they may not adhere well to the plastic and could flake off easily. It is also essential to avoid paints with solvents that can weaken the plastic or soften the surface material of the helmet, reducing its protective capabilities. Therefore, it is recommended to consult the helmet manufacturer to ensure the paint you select is suitable for the specific helmet material.
Additionally, it is important to consider the existing coatings on the helmet. In some cases, it may be advisable to start with a plain, matte helmet to avoid the need to remove any existing paint or glossy finish. If you must remove existing paint, exercise caution to avoid sanding into the outer plastic or fiberglass shell, which can compromise the helmet's structural integrity.
Furthermore, certain safety standards and stickers, such as the DOT sticker in the USA and the ECE sticker in Europe, must not be painted over or altered. These stickers indicate that the helmet meets the required safety standards, and tampering with them may render the helmet non-compliant with local regulations.
Lastly, if you plan to repaint a helmet for a specific activity, such as motorsports, it must pass the relevant safety tests, such as the ANDRA test for drag racing, to ensure it complies with the necessary safety regulations. Overall, when painting a plastic helmet, it is crucial to prioritize safety and adhere to local laws and manufacturer guidelines to avoid any legal repercussions and ensure the continued effectiveness of the helmet in protecting your head.
