Liquitex Airbrush Medium thins colours and mediums to a water-like state. It prepares paint for spray and airbrush techniques, increasing transparency and making paint behave like a watercolour, wash or stain. It is pre-filtered and pre-reduced for use with all consistencies of acrylic paint and mediums. This medium reduces airbrush clogging and paint build-up around the nozzle. Ideal for dry and hot climates.
