What You'll Learn
Washes, primers, and paint types
When preparing a plastic model for painting, there are several factors to consider, including the use of washes, primers, and the choice of paint type.
Washes
Washes are a technique used to add depth and realism to a model. They are typically applied after the base coat of paint has been applied. A wash is a thin layer of diluted paint or ink that settles into the recesses and panel lines of the model, creating shadows and enhancing the overall detail. Washes can be purchased pre-made or created by mixing paint with a medium like water or acrylic fluid.
Primers
Primers are essential when preparing a plastic model for painting. They provide a base for the paint to adhere to and help create a smooth finish. When choosing a primer, it's important to select one specifically designed for plastic, as some primers may contain chemicals that can dissolve the plastic. For example, Rustoleum contains acetone, which will damage your model. A good plastic primer will create a molecular bond with the surface, ensuring the paint adheres properly.
Paint Types
The choice of paint type depends on the desired finish and your personal preference. Acrylic paints are a popular choice for plastic models as they are easy to work with and can be thinned with water. They can be applied with a brush or an airbrush, depending on the level of detail you want to achieve. Enamel paints are another option, offering a durable and glossy finish. However, they require a stronger solvent for thinning and clean-up.
Additionally, when painting plastic models, it's important to avoid spray paints designed for other surfaces, such as lawn furniture. These paints may not adhere properly to the plastic and could result in a featureless, low-contrast finish that obscures the model's intricate details.

Spray paint vs airbrush
When it comes to spray paint versus airbrush for plastic models, there are several factors to consider. Firstly, spray cans are more user-friendly and suitable for beginners, whereas airbrushing may require some skill and practice to master.
Spray cans are a convenient option for priming and painting large pieces, offering a smooth finish, especially with specific products like the Tamiya fine surface primer. They are also more cost-effective, with options available at a range of price points, including affordable choices from retailers like Wal-Mart. However, it's important to choose hobby spray paints designed for plastic to avoid melting the material.
Airbrushing, on the other hand, provides finer control and a more precise finish, making it ideal for small details, weathering, and custom colour mixing. While the initial investment in an airbrush and air system may be higher, it can be more economical in the long run, as you can achieve a high-quality finish with less paint. Additionally, airbrushing allows for multiple light coats, which can be beneficial for certain projects.
When deciding between spray paint and airbrush, consider the level of detail required, your budget, and the time you're willing to invest in the project. For quick and simple applications, spray cans may be the way to go, but for intricate details and custom colours, airbrushing could be the better choice.

Disassembling the model
Firstly, carefully examine the model and identify any parts that can be easily separated or disassembled. This might include removable weapons, antennas, or other protruding pieces. Removing these parts will make the painting process easier and help you reach areas that would otherwise be difficult to access.
Next, using a small screwdriver or similar tool, carefully separate the pieces that can be disassembled. Be gentle to avoid breaking any small or fragile components. Place each piece in a logical order, so you know exactly how to reassemble the model later. It might be helpful to sketch a quick diagram or take reference photos to guide you during reassembly.
Once the model is disassembled, clean each part gently with a soft cloth or brush to remove any dust or debris. This will ensure that the paint adheres properly and creates a smooth finish. After cleaning, you can begin the process of priming and painting each piece.
If your model has complex or intricate details, consider using masking tape or liquid mask to protect certain areas during painting. This will help you achieve a clean and precise paint job, especially if you're using an airbrush or spray paint. Remember to test your paint on a small, inconspicuous area of the model first to ensure it adheres properly and doesn't cause any damage.
Finally, allow each piece to dry completely before carefully reassembling the model. Follow your reference photos or diagram to ensure each part is placed correctly. With a steady hand and careful planning, disassembling and reassembling your plastic model will result in a professional-looking finish that showcases all the exquisite details.

Brushes
When using brushes for painting plastic models, opt for synthetic brushes in a variety of sizes. Synthetic brushes tend to hold their shape and are less likely to fray or split, even with prolonged use. Smaller brushes are ideal for intricate details, while larger brushes can be used for base coats and covering larger areas. Synthetic sable or fox hair brushes are excellent choices. Natural hair brushes are an option, but they tend to be more expensive, and the benefit may not be noticeable unless you are an experienced model painter.
Paint
Acrylic modelling paint is the standard choice for most model enthusiasts. It is easy to work with and can be thinned by mixing it with water. Enamel paint is also an option but remember to mix it thoroughly before use, as it tends to separate when sitting for long periods. Consider the colour and finish you desire for your model, as paint can come in various colours and finishes, such as matte, satin, or glossy.
Primer
Primer is not always necessary, especially if your model is made solely of plastic. However, if your model is made of multiple materials, primer can help produce a uniform colour and improve paint adhesion. White primer is suitable for light colours, while grey primer is better for dark colours. Spray primers are commonly used, and it is recommended to hold the can about 10-12 inches away from the model and spray in quick, even strokes. Always remember to shake the primer can well before use and test spray on a separate model or surface to ensure proper paint agitation and environmental conditions.
Workspace Setup
Prepare your workspace by setting up a stable surface and a base, such as old newspapers, to protect the area from paint splatters. Ensure you have sufficient bright light, ideally natural daylight, to illuminate all parts of the model well. Working outdoors in a well-ventilated area or a room with good ventilation is recommended to protect yourself from paint fumes.

Paint safety
When preparing to paint plastic models, there are several safety precautions to keep in mind, especially when working with certain types of paints and paint thinners. Here are some guidelines to ensure safe handling of materials during the painting process:
Work Area Ventilation:
It is important to work in a well-ventilated area to avoid inhaling paint fumes. Set up your workspace in a room with open windows or doors to ensure proper airflow. If working with lacquer paints, take extra precaution as they have an extremely strong odour. Use a spray booth for fume extraction, or opt for outdoor painting if possible.
Respiratory Protection:
When working with solvents, lacquers, or paints with strong odours, wear a respirator with organic solvent filters. This will help prevent the inhalation of toxic fumes, which can be harmful to your health. It is also advisable to wear a mask when working with lacquer paints to protect yourself from their overpowering odour.
Paint Handling and Mixing:
Always read the labels and instructions on the paint cans to understand the specific safety precautions for each type of paint. Some paints, like enamels, are oil-based and may have a slightly strong odour. Acrylics are water-based and generally have a milder smell. When mixing paints, follow the recommended paint-to-thinner ratios provided by the manufacturer. Use corresponding thinners for each paint type, and mix them carefully and diligently.
Surface Preparation:
Before painting, ensure your work surface is clean and free of any contaminants. Use a dedicated workspace or a drop cloth to protect the surrounding area. Clean the plastic model with warm water and soap to remove any dust or residue. This step will ensure that your paint job is not compromised by unwanted particles.
Spray Painting Safety:
When using spray paint, maintain a distance of 10-12 inches (25-30 cm) between the spray can and the model. Use quick, even strokes to apply the paint uniformly. Avoid spraying in enclosed spaces and always direct the spray away from your body and face. Spray painting should be done in a well-ventilated area or outdoors to minimise the risk of inhaling paint fumes.
Hand Protection:
When handling paint and paint thinners, it is advisable to wear gloves to protect your skin from direct contact with chemicals. This is especially important if you have sensitive skin or are prone to allergic reactions.
