So, I started mounting my linen canvas onto birch and masonite panels and, one of the owners of an art store, told me not to do that, because the painting will crack over time.
So, I did some research. There's a ton of conflicting answers out there. Right now, I use PVA glue to canvas. Some people say that you should use Miracle Muck. Other's say that you should use Acrylic Gesso. Some people say that Acrylic Gesso is non-archival, so don't use that, it'll crack the painting, later. Some people say "Never mount the canvas", just gesso the board.
Personally, I've gotten to really like the Cassein linen canvas on the board, but I really don't want someone to purchase a painting and 10 years down the line, the painting starts to crack on them. Note: This is only for 9 x 12 paintings. For larger sizes, I use pre-stretched canvas (which, some people say to never do that because the painting will crack due to humidity changes. However, I have paintings that are 6 years old and they have never cracked).
So, before I start going into full production mode to mount a lot of panels, any recommendations?
