Occasionally, I will use pencil to sketch on an acrylic gessoed board before applying oil. Because, the oil can pick up some of the graphite I would like to use a spray fixative to keep the pencil drawing in place. Do you think this would affect the integrity of the painting?
As far as I know, that’s part of its purpose. My Utrecht can says"…produces a matte surface that can be worked over easily with most art mediums." I have used it under paintings for years, assuming it’s just a layer of another type of plastic. Lots of information out there:
Thanks Connie for these very useful references.
