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 colours for airbrush application. Mixing colours with Airbrush Medium will ensure that the colours 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 Colour; there is no need to strain. Mix Liquitex Airbrush Medium into Heavy Body Artist Colour and strain to remove any undissolved colour. Start by mixing 50% Liquitex Airbrush Medium to colour and mix thoroughly. Add further Airbrush Medium as necessary to facilitate flow through the airbrush. Each colour may require a different percentage of Airbrush Medium to colour, due to variation in colour 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.
