Liquitex Fluid Airbrush Medium is a pre-filtered, read-to-use medium that easily thins any acrylic, water colour, or gouache to the right consistency for spray application. An excellent choice for colour washes and water colour techniques when used with acrylic colours. Mixes well with other mediums to adjust the body and handling properties. Maintains integrity of acrylic even at high dilutions, and decreases airbrush clogging and paint build-up. How to use   Fully intermixable with all Liquitex products. Start by using in a 1:1 ratio with Soft Body Acrylic or Acrylic Ink, adjusting levels according to color chosen as each varies due to pigment size and and concentration. Airbrush nozzle size and spraying pressure will determine your ratio, so experiment to get the optimum mix. Stir gently until the mixture is fully blended - if bubbles appear, leave it to sit while the bubbles rise and disappear. If using with Heavy Body, strain once mixed to remove any particles of undissolved color. Clean out immediately after use before acrylic has a chance to dry -Do not allow paint to dry in the airbrush - always wash it through with warm soapy water, a water/ammonia mixture, airbrush cleaner or alcohol. Do not shake. Do not use with any non-acrylic media.   Use with Liquitex Acrylic Ink, Liquitex Heavy Body and Liquitex Soft Body Acrylic colours.
