I have used a Winsor & Newton fixative for my pastel works. However, when I touch it, the pastel still comes off. Is there any way I can completely fix my pastel paintings? I sprayed fixative several times during painting, and few days after each time that I used it, I painted the new layer on it. And after the painting got completed I also sprayed fixative for one last time.
I dont do any work with pastels, but my friend does. I asked her what a good one would be, and she said that the Sennelier fixative works pretty well. Its a final fixative, and it gives a matte finish as well. It works best if you use a few thin coats, drying in between. Its about $16, which is the cheapest one, but its also really good. Good luck with your projects!
No fixative will make pastels totally sealed and irremovable, at least not without totally changing the look of the pastels (typically darkening and dulling them). So it is a balance between protection and look. Fixing will make the under layers workable, strong enough to take layers above without too much mixing, but a pastel drawing will always be fragile.
