Liquitex Airbrush Medium is a low viscosity, pre-mixed blend of acrylic polymer emulsion, water, retarder and Flow-Aid™. It is ready-to-use, pre-filtered and pre-reduced to the proper consistency for airbrushing techniques. Add as much or as little as desired. It easily thins acrylics or any water-soluble paints to a sprayable consistency while decreasing airbrush clogging and paint build-up during spraying. Liquitex Airbrush Medium mixes easily with all Liquitex paints, mediums and gessos to produce paint with the proper viscosity for airbrushing. It contains specific additives designed to retard drying time and improve the flow of acrylic paint through an airbrush.
