In my city, the subway advertisements are made of thick pressed paper, which is nice to draw and paint on. I’ve used it for practicing large composition, mostly with coal, but I’ve also used acrylic spray paint as a primer and painted some with oil or acrylic
The oldest charcoal drawings (maybe 10 years old or so) have yellowed a lot through the years. The ones primed with spray paint and painted with oil or acrylic haven’t yellowed to the point of noticeable changes, but the oldest of those is maybe 6 years old.
I was taught art by my grandmother who would have been well over 100 if she was still with us, so the materials she worked with were very different, and I am new to the concept of archival quality- but my whole family as well as friends, strangers and my partner are all really encouraging me to start selling my art, instead of just keeping piles and piles of paintings sitting around.
And I’ve understood that if someone buys a painting, “my method seems to last for at least 5 years” isn’t what they’re looking for.
I really want to use advertising cardboard as I’ve grown to love the smooth surface, the lightweight feel, and the feeling of participating in a story (for example, I did a series of portraits of the worlds strongest female weight lifters who are all very large women, on the back of the ozempic ads because I felt inspired)
As well, the amounts of this material the city wastes every month on replacing the ads and throwing away the old ones is completely staggering. That process in itself inspires me to never stop painting/drawing.
So my question is, how can I understand how this concept of archival works when it comes to paper? Is gesso good enough of a primer if a few layers are added?
Should I paint dynamically with the yellowing in mind?
