Liquitex offers the broadest range of acrylic mediums to inspire creativity at every stage of the painting process. Liquitex offers a variety of specialty products including Fluid Mediums, Gel mediums, Texture Gels and Additives which have been specifically designed to achieve various techniques, applications and special effects. Liquitex Airbrush Effects Painting Medium is specifically formulated to thin acrylic colors for airbrush application. Mixing colors with Airbrush Medium will ensure that the colors do not lose their flexibility, durability and adhesion. This low viscosity, ready to use medium is pre-filtered and pre-reduced to the required consistency for airbrush techniques -- add as much or as little as desired. Formulated for maximum flexibility and adhesion, will not chip or crack on canvas. Can be applied to any material or surface that will accept traditional acrylic media, such as canvas, paper, wood, etc. Liquitex Texture Gels are lightweight, non-toxic, and dry to a water-resistant, non-yellowing surface. APPLICATION: Mix Liquitex Airbrush Medium into Soft Body Artist Color; there is no need to strain. Mix Liquitex Airbrush Medium into Heavy Body Artist Color and strain to remove any undissolved color. Start by mixing 50% Liquitex Airbrush Medium to color and mix thoroughly. Add further Airbrush Medium as necessary to facilitate flow through the airbrush. Each color may require a different percentage of Airbrush Medium to color, due to variation in color pigment size and concentration of pigment. Airbrush nozzle size and spraying pressure (PSI) will determine the ratio of Airbrush Medium to paint mixture. Larger nozzles allow for greater amounts of paint in the mixture. Keep airbrush wet during use ;do not allow paint to dry in airbrush. Clean airbrush with water water/ammonia mixture, Liquitex Professional Acrylic Ink Pen Cleaner, airbrush cleaner, or alcohol.
