Painting plastic models is a highly rewarding and fun hobby that can be taken to the next level with the right tools and techniques. The process can be time-consuming, requiring intricate detail work and patience while waiting for layers to dry. Before painting, it is important to clean the model with soap and water to ensure a smooth finish. There are various types of paint to choose from, including water-based and solvent-based options, with enamel and acrylic modelling paints being popular choices. It is also important to select the right brushes, with synthetic sable or fox hair brushes being ideal for small, intricate strokes.
| Characteristics | Values |
|---|---|
| Brush type | Synthetic brushes are best for painting plastic models. Smaller brushes are recommended for intricate details. |
| Primer | Skip the primer unless the model is made of multiple materials or will be handled regularly. If using a primer, use a white spray primer, holding the can 10-12 inches away from the model. |
| Paint type | Water-based and solvent-based paints are the two main types. Acrylic paints are commonly used for plastic models and are good for airbrushing. Enamel paints are also used but can be tricky to airbrush. |
| Paint preparation | Mix the paint for 20-30 seconds before pouring it onto a palette. |
| Model preparation | Clean the model with soap and water before painting to ensure a smooth finish. |
| Base coats | Use as few strokes as possible when painting base coats. |
| Top coats | Many modelers finish with a clear top coat to protect the paint and provide a consistent finish. |

Cleaning the model
Before painting a plastic model, it is important to clean it thoroughly to ensure the paint adheres well and does not chip off easily. Here is a step-by-step guide to cleaning your plastic model:
Firstly, inspect the model for any release agents. If the plastic surface feels smooth, slick, or slippery, it likely has a release agent on it. This can prevent paint from adhering properly, so it is important to wash it off.
Next, gather your cleaning supplies. You will need a mild dish soap, a soft-bristled toothbrush, clean water, and some towels. Optionally, you can also use rubbing alcohol and/or Dettol.
Now, it's time to wash the model. Mix some mild dish soap with warm water to create a soapy solution. Dip the toothbrush into the solution and gently scrub the entire surface of the model. Pay extra attention to nooks and crannies, ensuring all surfaces are thoroughly cleaned. Rinse the model under clean, running water to remove any soap residue.
After rinsing, you can optionally soak the model in rubbing alcohol overnight. This will help remove any remaining oils or residue. If you don't have rubbing alcohol, you can also soak the model in Dettol for a day or so. Just be sure to rinse the model with clean water and dry it thoroughly afterward.
Finally, use a soft cloth or towel to dry the model. You can gently pat or blot the model dry, being careful not to scratch the surface. Make sure the model is completely dry before you start painting it.
By following these steps, you will ensure that your plastic model is clean and ready for painting, helping you achieve a smooth and long-lasting finish.

Choosing the right brush
Brush Quality
It is advisable to invest in high-quality brushes, as they can significantly impact the final outcome of your project. Avoid cheap brushes, as their inconsistent quality may hinder your work. Look for brushes with durable bristles that will not shed or melt when exposed to solvents.
Brush Material
Natural sable brushes are a popular choice for painting plastic models. They are available in premium and moderately priced options. Sable brushes are known for their ability to hold paint well and maintain a sharp point, making them ideal for detailed work. Synthetic brushes, such as the AK-Interactive series, are also an option if you're looking for something more affordable.
Brush Shape and Size
Consider the size and shape of the brush bristles. For miniature painting and detailed work, smaller brushes with sharp points are generally preferred. The Winsor & Newton Series 7 Kolinsky Sable Brush set is a popular choice among many painters. However, keep in mind that the ideal brush size may vary depending on the specific area you are painting.
Brush Type
The type of brush you choose depends on the paint you are using. For example, when using water-based acrylics, consider using brushes designed for watercolours, as they can hold more water and maintain a workable tip for longer. On the other hand, if you plan to use enamel paints, you may need a different brush type that can create a smooth surface more easily.
Personal Preference and Comfort
Ultimately, the "best" brush is subjective and depends on your personal preferences and comfort. Some people may prefer a different brand or type of brush that they find easier to work with. It is recommended to try out different brushes to find the ones that suit your painting style and provide the best results for your plastic models.

Priming the model
Priming a plastic model is an important step in the painting process. Primer helps the paint adhere better to the plastic surface, which is otherwise smooth and may not hold paint well. This is especially important for large or highly detailed models that you will be handling a lot during the painting process, as the oils from your skin can dissolve the paint.
To prime a plastic model, start by choosing the right primer for the job. There are many types of primers available, so select one that is suitable for plastic models. You can test the primer on a plastic spoon before applying it to your model to ensure it will work well.
Once you have your primer, prepare the surface of the model by cleaning it with mild soap and water to remove any dirt, grease, or residue. This will help the primer adhere properly. After cleaning, dry the model thoroughly.
When the model is dry, apply the primer following the instructions on the product. You can use a brush or spray to apply the primer, depending on the type you have chosen. Be sure to work in a well-ventilated area and follow any safety instructions provided by the manufacturer.
Allow the primer to dry completely before moving on to the next step in your painting process. The drying time may vary depending on the type of primer and the humidity in your workspace, so check the manufacturer's instructions for guidance.

Mixing the paint
Mixing paint is an important step in the painting process. Firstly, it is essential to ensure that your paint is thoroughly mixed before pouring it onto a palette. Enamel and acrylic modelling paints tend to separate when left sitting in their bottles for a long time. To mix the paint, use a mixing stick or a spare brush, and mix for 20-30 seconds.
Once the paint is mixed, you can pour it onto your palette. If you are using a wet palette, you may find it easier to mix your paints. A wet palette can be easily made at home and is cheap to create.
When mixing paints, it is important to remember that you should only mix paints of the same type. For example, you can mix two acrylic paints together, but you should not mix an acrylic paint with an enamel paint. This is because different types of paint have different chemical compositions, and they will not mix well.
If you are thinning your paint, it is important to get the right ratio of paint to thinner. This will depend on the type of paint you are using, the temperature, humidity, and the equipment you are using to apply the paint. You can test the consistency of your paint by running it up the sides of a glass. If it runs off too quickly, it is too thin. If it sticks and doesn't run, it is too thick.

Finishing with a clear coat
When choosing a clear coat, you can select from lacquer, enamel, or acrylic options. Lacquers tend to go on very smooth, but they can have a strong odour and a higher probability of reacting with previous layers if not applied carefully. Enamel is a good option if you want to brush paint, as the solvents "bite" into the plastic. Acrylics are better for airbrushing.
If you have used a water-based paint for your model, it is recommended to avoid lacquer, as it can react poorly with the base coat. Instead, opt for an acrylic or enamel spray to finish your model.
Additionally, consider the purpose of the clear coat. If you are applying decals or doing panel washes, a gloss coat is a better option. For dry brushing, heavy oil staining, or a flat finish, a matte coat is more suitable.
Finally, always test your clear coat on a spare piece of plastic before applying it to your model. This will allow you to see how it works and ensure that it does not damage your paint job.
