Grumbacher Final Fixative Gloss Spray is used to fix and protect dry media such as pastels, charcoal, and graphite. Always test on a scrap surface with a similar media application as your final work before use. Use in a well ventilated area with temps above 65 degrees Fahrenheit and relative humidity below 65%. Follow safety instructions on can. Fixatives may darken media depending on the media, the amount of media, and the substrate. Do not over-apply as it will cause a more dramatic color shift and may cause pastels to dissolve. Shake 1-2 minutes before use. Clear the nozzle by spraying a few blasts onto scrap paper, turn can upside down and spray until only gas comes out. Set work vertically and spray 12 inches from the artwork. Overlap spray about 1/2 inch on each pass with light coats. Turn artwork 90 degrees and wait 5-7 minutes between each coat. Allow to dry completely before touching. Made in USA.
