When it comes to choosing the right brush for painting plastic models, there are several factors to consider. Firstly, it is essential to select a brush with a sharp point and good spring back, such as those offered by Winsor & Newton in their Series 7 collection. Additionally, a brush that can hold an ample amount of water is beneficial for maintaining consistent paint flow. While premium sable brushes are recommended for their quality, affordable synthetic brushes like the AK-Interactive series are also a popular choice. Thinning paint with a suitable medium, such as alcohol or glazing liquid, can enhance the painting process and achieve desired effects. Personal preference also plays a role, as some artists prefer the control and theatrical style offered by hand-painting, while others opt for the thin layers and absence of brush strokes that airbrushing provides.

What You'll Learn

Brushes with natural or synthetic bristles
When choosing a paintbrush for plastic models, there are two main categories of brushes to choose from: natural and synthetic. Natural bristles are made from animal hair, such as hog, badger, sable, squirrel, goat, pony, or ox hair. They are ideal for oil-based paints and watercolours as the oil conditions the animal hair, making it more pliable. Natural bristles are also better at holding more watercolour paint and distributing colour more evenly. However, they are not compatible with acrylic paints, which can damage the delicate hairs. Natural brushes are also more expensive and may raise concerns about animal rights and environmental sustainability.
Synthetic bristles, on the other hand, are made from man-made fibres like nylon and polyester. They are suitable for artists of all skill levels and are versatile, budget-friendly, and suitable for various mediums. Synthetic brushes can handle either type of finish but are primarily used for the application of water-based products. They are also better at holding and picking up paint when dyed. However, they may not provide the same traditional feel and shape retention as natural brushes.
For plastic models, synthetic brushes may be a better choice due to their versatility and compatibility with water-based paints. When choosing a synthetic brush, look for brushes with nylon or polyester bristles, as these fibres pick up and hold paint better when dyed. Some synthetic brushes have bristles coloured white, orange, blue, or red.
It is important to consider your needs, preferences, desired medium, artistic goals, and budget when deciding between natural and synthetic brushes. For example, if you are a beginner, synthetic brushes provide an accessible and affordable option to explore different mediums and develop your artistic skills. On the other hand, if you mainly paint with oil-based paints and are looking for a smoother application, natural brushes may be a better investment.
Additionally, the shape and size of the brush are also important factors to consider. Round, fat brushes hold more paint, while sharp, chiselled-edge brushes are better for cutting into corners and crevices. For plastic models, a mix of brush sizes and shapes may be useful for achieving the desired details and effects.

Brush size and shape
For plastic models, it is generally recommended to use a mix of premium sable and affordable synthetic brushes. Sable brushes, made from natural hair, are known for their ability to hold paint well and snap back into shape quickly. They are ideal for detail work and can produce consistent paint flow. Synthetic brushes, on the other hand, offer a more cost-effective option and can be suitable for various tasks, including weathering and working with solvents. When choosing synthetic brushes, look for options that are durable and less likely to shed bristles over time.
The size of the brush is another critical factor to consider. For plastic models, it is often recommended to use fine-tipped brushes for detailed work. Smaller brushes allow for greater precision and control when painting intricate details or small areas. However, keep in mind that smaller brushes may require more frequent dipping, as the paint tends to dry on them more quickly.
Additionally, consider the shape of the brush handle. Some brushes feature a rounded triangular design, which is claimed to provide the painter with better control. This shape may help reduce rotational slippage, allowing for more precise brush strokes. However, the effectiveness of this design may vary depending on individual experiences and preferences.
When choosing brush sizes, it is advisable to have a range of options available. Different parts of the model may require different brush sizes. For example, when painting a T-34/76 model, you may need a variety of brush sizes to achieve the desired results. Additionally, consider the paint type and its thinning requirements. Thicker paints may work better with larger brushes, while thinner paints are more suitable for smaller brushes to avoid excessive dripping.
In conclusion, when selecting brushes for plastic models, consider a combination of sable and synthetic options in various sizes. The sable brushes will provide precision and paint retention, while the synthetic brushes offer durability and affordability. Pay attention to the handle design and choose shapes that feel comfortable and provide you with the necessary control. By having a range of brush sizes and types, you can tackle any painting project with confidence and achieve the desired results.

Brush cost
The cost of brushes for painting plastic models varies depending on the type of brush and the quality. While some modellers prefer to use an airbrush for a smooth finish and thin layers, others opt for traditional paintbrushes. For the latter, there are various options available, from affordable synthetic brushes to premium-grade natural brushes.
Synthetic brushes, such as the AK-Interactive series with its distinctive orange handle, offer a cost-effective option for those on a budget. These brushes provide good value for money, with some users reporting that they have lasted for years. On the other hand, cheap "dollar store" brushes should be avoided as their quality tends to be inconsistent, and they may not hold up well when exposed to solvents.
For those seeking a natural brush option, red sable brushes offer a moderately priced choice, while Kolinsky sable brushes are considered premium-grade and come with a higher price tag. The Winsor & Newton Series 7 brush is also recommended by some modellers and falls into the premium brush category. However, some users have reported issues with the quality of this brush in recent years, noting that the bristles tend to split and do not hold their shape.
When working with water-based paints, it is advisable to choose brushes designed for watercolours, as these have a sharp point, good snap, and can hold an adequate amount of water for consistent paint flow. These brushes may be more expensive, but they can enhance the painting experience and improve the overall finish of the model.
Overall, the cost of brushes for plastic models can range from a few dollars to premium options costing significantly more. The key is to select brushes that offer the best value for money, providing a balance between quality and affordability to suit the specific needs and budget of the modeller.

Paint type
Painting plastic models can be an intricate process, but it's fun and rewarding. When it comes to choosing the right paint, there are a few options to consider.
Firstly, acrylic modelling paint is the standard choice for most model enthusiasts. It is easy to work with and can be thinned by simply mixing it with water. Acrylic paint is also unlikely to damage your plastic model. However, it may not be the most durable option if your model is going to be handled frequently or subjected to heavy use. In such cases, other types of paint might be more suitable.
Enamel paint is another option, and it is known for its durability and ability to withstand wear and tear. However, it requires more specialised tools and techniques for application and can be more challenging to work with than acrylic paint. Enamel paint also typically takes longer to dry, which can be a factor to consider depending on your project timeline.
Additionally, when working with either acrylic or enamel paint, it's important to mix the paint thoroughly before use. These types of paint tend to separate when stored for extended periods, so mixing ensures a consistent colour and texture during application.
Ultimately, the choice of paint depends on your specific needs and preferences. Acrylic paint is generally user-friendly and suitable for most projects, while enamel paint offers greater durability but requires more specialised handling. Considering the level of detail, the intended use of the model, and your own skills and comfort with different types of paint can help guide your decision.

Paint thinning
When it comes to thinning paint for plastic models, there are a few different techniques and products to consider. Firstly, it is important to select the appropriate type of paint for brush painting on plastic models. Acrylic or enamel paint is typically recommended for this purpose. While acrylic paints are non-toxic and easy to work with, they can leave brushstroke marks. Enamel paints, on the other hand, offer great coverage and a strong paint surface, but they take a long time to harden.
For thinning acrylic paint, the simplest method is to mix it with water. Acrylic paints are available in both airbrush-ready and regular brush-on versions. When thinning the brush-on version, it is advisable to have both types as thinning for airbrushing can be challenging for beginners. Additionally, pre-thinned acrylic paints, such as Vallejo Acrylics, are also available and can be brushed on evenly without the need for thinning.
For thinning enamel paints, a dedicated thinner is usually required. Tamiya, for example, offers a range of enamel paints and their own thinner, X-20A, specifically designed for brush painting. However, some people have found that using Tamiya's thinner can still result in paint clumping or lifting up previous coats. In such cases, an alternative method is to use an impermeable palette and mix a small amount of paint with a few drops of the thinner until it is consistently combined before applying it to the model. It is important to note that lacquer thinner should be avoided for hand-brushing as it can lift up the colour coat.
When thinning paint, it is generally recommended to apply several thin layers of diluted paint rather than a single thick coat, which can ruin the model. Additionally, it is crucial to let the paint dry before retouching and to use long strokes to avoid brush marks.
