Schmincke Universal Fixative Aerosol

Spray this fixative at room temperature and move the can from side to side, top to bottom to give the best coverage on your artwork. It is best vertically positioned between 30 and 40cm away from your work, although also works at a slight incline. Ensure that the change in direction of spray occurs away from the artwork. Only use on work that is 100% dry.
The level of gloss given to your work will depend on the absorbance of the surface, painting technique used and the thickness of the film. Applying this fixative as an intermediate layer can be helpful.
Using too much fixative on materials low in binding agents will cause the medium to darken. If too much of this fixative is used on paper it can make its surface more transparent.
Although this fixative offers some UV protection it is always advisable to use high-quality lightfast artists paints or inks.
If the spray nozzle becomes clogged it can be cleaned with acetone.
