You can use acrylic polymer, artist-quality PVA, or acrylic and casein size to seal canvas for oil painting. Be aware that there are over 50 different types of formulations of PVA and only a few are of the quality needed to make permanent paintings, so look for a brand intended for preparing paintings.
Is there a vegan or vegetarian product that you can use instead of rabbit sking glue, for sizing a canvas before applying gesso?
