Using An Air Brush To Paint Scale Models


Introduction to Airbrushing for Scale Models


Airbrushing is a popular technique used in scale modelling to create a smooth and even finish on models. The airbrushing process involves using pressurized air to atomize paint, which is then sprayed onto the model's surface. This process allows for greater control and precision when applying paint, resulting in a more professional-looking finish. Airbrushing has become increasingly popular among scale modellers due to its many benefits compared to traditional brush painting techniques.




One of the main benefits of using an airbrush for scale models is the ability to effortlessly apply an even coat of paint. Airbrushing allows for a consistent application of paint, resulting in a smooth finish with no brush marks or streaks. Additionally, lacquers dry quickly when used with an airbrush, which can significantly reduce the time it takes to complete a model. Airbrushing also makes it easier to paint as you go, allowing for greater control and precision when working on intricate details.


There are several types of airbrushes available for scale modelling, including single action and double action airbrushes. Single action airbrushes have a trigger that controls the air flow, while a knob at the front or back of the airbrush controls the paint flow. Double action airbrushes allow for greater control over both the air and paint flow, providing more precise and detailed results. When choosing an airbrush, it is important to consider the type of model being painted and the level of detail required. Some popular airbrushes for scale modelling include the Iwata Eclipse HP and the Badger Patriot 105.



Preparation and Techniques for Airbrushing Scale Models


Preparation is key when it comes to airbrushing scale models. One of the most important aspects of preparation is cleaning and maintaining the airbrush equipment. To ensure proper functioning, the airbrush should be flushed with water to remove any residual paint, followed by cleaning with an airbrush cleaning fluid. Additionally, the needle, nozzle, and nozzle cap should be soaked in rubbing alcohol and wiped clean. Regular maintenance of the airbrush equipment can prevent clogging and ensure consistent paint flow, which is necessary for achieving the desired results.


Choosing the right paints and thinners is also crucial for successful airbrushing. Acrylic paints are a popular choice for airbrushing due to their quick drying time and easy clean-up. When choosing a thinner, it is important to use one that is compatible with the paint being used. For example, water can be used to thin acrylic paints, while alcohol-based thinners are suitable for enamel paints. It is also important to mix the paint and thinner in the correct ratio to achieve the desired consistency. Some modellers prefer to use premixed model paints that are specifically formulated for airbrushing.

Airbrushing techniques vary depending on the surface and texture of the model being painted. For fine detail work, a thinner paint consistency may be necessary.



Experimenting with different airbrushing techniques, such as varying the air or paint supply, can also create a variety of effects. Practising on natural elements such as rocks or sticks can be a great way to improve airbrushing skills and experiment with different techniques. It is important to note that while airbrushing can produce a smooth and even finish, it is not always necessary, and brush painting can still be a viable option .


Tips and Tricks for Achieving Professional Results



Using an airbrush to paint scale models can produce professional-looking results with the right techniques. Layering and blending techniques are crucial for achieving smooth colour transitions on a surface. Airbrush blending involves using an airbrush to apply several coats of different colours, creating a smooth transition between colours. Zenithal highlighting is another technique that can be achieved with an airbrush, allowing for quick and easy blending and layering of paints. It is important to use thin coats and allow each layer to dry before applying the next to avoid disturbing or lifting a previous layer. Additionally, some ready-to-use airbrush colours may need to be thinned for optimal spray ability, especially for thicker materials like metallics. Experimenting with different layering and blending techniques can lead to achieving professional-looking results.


Masking and stencilling techniques can also enhance the final product when using an airbrush for scale model painting. Stencils and masks can be used to create intricate designs and patterns on a model. It is important to use the right type of stencil or mask for the desired effect and to ensure that the stencil or mask is firmly in place to avoid paint bleeding or smudging. Additionally, using a proper sealant can help protect the final product from wear and tear. Semi-gloss or gloss finishes are commonly used for scale models, but it ultimately depends on the desired effect. Experimenting with different masking and stencilling techniques, as well as finishes, can help achieve a unique and professional-looking final product.


Proper preparation and maintenance of the airbrush is also crucial for achieving professional results. Thinning the paint to the proper viscosity is important for optimal spray ability. Using airbrush-ready liquids can simplify the process for beginners. Additionally, cleaning the airbrush thoroughly after each use can prevent clogging and ensure consistent spray patterns. If the paint finish begins to look coarse or bumpy, it may be due to a clogged airbrush nozzle or paint that is too thick. Troubleshooting these issues and maintaining the airbrush can lead to consistent and professional-looking results.
