A fixative is a liquid which is sprayed over a drawing to better preserve it & prevent smudging. Artists often question whether drawings should be fixed, as spray fixative can alter the look of a drawing if applied too heavily by darkening or coarsening the color. Framing behind glass is considered the best protection (& in the case of oil pastels, the only option), but isn’t always practical.
Permanent fixatives are used on a finished drawing as a light sealant, while a workable fixative is used during the drawing process to extend the “tooth” of the surface allowing pastel to be built up & is best applied before adding the final layer to minimize the diminishing of color intensity.
Fixative also reduces wax bloom in colored pencil works & prevents loss of fine charcoal particles. Lascaux is the choice of the Wet Paint staff for a permanent fixative. This conservator-quality spray is as clear as water, non-yellowing & resistant to aging. It is suitable for fixing drawings in soft pastel, pencil & charcoal & is used to protect digital prints as well.
