This includes acrylics, watercolours, oils, enamels, automotive finishes, alkyds. For paints that include aggressive solvents i. Rubber is normally replaced by PTFE for such applications. Cleaning is quite straightforward. Then spray through with the suitable solvent until the airbrush is thoroughly clean.
It is essential to be very careful between colour changes to ensure there is no residue left. If using dark and light colours together it is worth considering having 2 or more airbrushes to eliminate cross contamination of colours. At the end of your session, clean your airbrushes thoroughly.
Many manufacturers supply ready made airbrush cleaner in aerosol form. Masking is possible using masking tapes, frisket which is a self adhesive masking film or other proprietary films or stencils.
You can use a compressor of which there are many types but it must have an adjustable regulated output or a propellant can with a regulator or a spare tyre with a regulator. You will need a minimum of 0. Pressure setting is adjusted to suit your application. Visit our Books section for a wide selection of modelling titles. Alternative YouTube is excellent platform for airbrushing tip and techniques. Read and understand the Health and Safety instructions from the manufacturer of the product you are spraying.

This depends on your application. Airbrushes come in 2 main types:- Single Action — where pressing on the trigger simultaneously turns on the air and sprays the liquid in the paint cup. Airbrushes work by feeding paint into a stream of air, and then focusing that stream on the surface that you want to paint.
The Master-branded airbrush I recommend here is a gravity feed airbrush, meaning that all you need to do is put some paint in the jar and it will find its way down and into the stream of air on its own. Use a few drops of thinner to keep it flowing. You could also mix them in the pot right on the airbrush, but that risks bending the needle. This Master airbrush is a dual-action airbrush, meaning the trigger has two functions.
Press down on the trigger to get the air flowing, and pull back on the trigger to increase the flow of paint. To avoid getting paint stuck to the nozzle — which can lead to paint splatters and jams — begin and end every press of the brush with air.
The pattern should go like this:. Start with black primer, and go slow. It will take some time to get the feel for how much paint is going onto the model. Remember to hit the model from all angles — including from underneath. What you should be left with is a fine coat of black primer. Stick with that black primer for as long as you like, and prime a good half-dozen or so minis before your pot runs out of paint.
The miniature is also dry and ready for additional layering much more quickly. Cleaning an airbrush is a real pain, which is why I like to paint big batches of miniatures a single color at a time.
Smooth, quick-drying coats of primer are just the beginning. There are a lot more advanced techniques that an airbrush is good for. Zenithal highlighting is another excellent technique, but one that takes slightly more specialized materials.
Basically, you start with a dark color and then apply a lighter color from above — as though the miniature was being lit by the sun at its zenith. You can also slip a coat of gray in between to give a more gentle transition. Trouble is that when you apply your base coat, you need to be able to see this high-contrast layer through it.
A good option that I recently stumbled upon is using Citadel Contrast paints. Once inside the airbrush gravity continues to assist by pulling the paint into the atomisation chamber where it is introduced into the high pressure air flow and is atomised into a fine mist.
A siphon feed airbrush holds the paint in a jar underneath the airbrush body and uses the pressure of the compressed air passing through the airbrush to draw the paint up from the paint cup via a paint tube. When the paint reaches the end of the paint tube it is introduced into the airflow to atomise and be sprayed onto your work.
A side feed airbrush is one that has the paint cup positioned directly to the side of the airbrush body, and could be considered both a siphon feed and gravity feed airbrush depending on how you use it.
A single action airbrush is labelled as such due to the single movement capability of the trigger, in that it can only be pressed down and this will provide a fixed amount of paint. It essentially works exactly like a can of spray paint does. On a single action airbrush the amount of paint that sprays can be controlled, but rather than this be dictated by the trigger it is altered by turning a part of the airbrush that adjusts the opening of the nozzle so that more or less paint can flow through.
A double action airbrush is labelled as such due to the double, or dual, movement capability of the trigger, in that pressing down on the trigger delivers air and pulling back on the trigger will deliver successively more paint as the trigger moves backwards.
The further you pull the trigger back on a double action airbrush the more paint comes out, allowing for greater paint control especially during detail painting where you may want more or less paint on the fly.
A double action airbrush is often considered better for detail work, however a single action airbrush can also manage very good fine detail albeit with potentially more manual adjustment of your hardware. Internal mix refers to where the paint is mixed with the high pressure airflow, with the mixing occurring inside airbrush body in what is called an atomisation chamber.
