SpectraFix Spray Fixative is the ultimate fixative for charcoal, pastels, pencils, watercolours and gouache as it contains no resin varnishes or other chemicals or chemical propellants to darken the value and alter the hue of your work. Also perfect for use to secure underpainting before varnishing or applying oil paint.

SpectraFix is formulated from a blend of art-grade natural milk casein, water and pure grain alcohol to produce a colourless, rapid drying, water-resistant and non-yellowing film. The alcohol evaporates rapidly taking the water with it leaving only a thin layer of casein which dries quickly to a protective and archival acid free matte film. Also protects fragile pastels without colour change!

SpectraFix is not packaged in a pressurized aerosol can as the necessary chemical propellant used may cause unforeseeable effects to colour values and hues, your health and the environment. Instead, SpectraFix uses a finger-operated, fine mist sprayer to produce a vaporous mist that has only a minimal effect on a colour's value and does not change the hue. The colours will remain fresh and vibrant even after several layers of SpectraFix. Safe for use indoors or in the classroom!
