Art fixative sprays from Krylon. Generally speaking, a fixative is a stabilizing or preservative agent, usually a liquid (similar to varnish), that is sprayed over a finished piece of artwork to better preserve it and prevent smudging. Modern fixatives are usually alcohol-based. Certain manufacturers produce fixatives specified for a certain media only, such as soft pastel fixatives. Modern fixatives are elevated in quality in terms of transparency, colorlessness, age-resistance, and UV resistance, preventing yellowing and fading caused by exposure to light. Examples of artwork media requiring fixative include drawings done in pencil, charcoal, pastels. An artist will often fix layers of a work in progress, in order to easily add further layers. Such a technique requires a workable fixative. Fixative is most commonly available in aerosol sprays. All Krylon spray fixatives are made in the USA.
