What is your favorite glue for hanging murals painted on canvas? I am planning on using heavy duty wallpaper adhesive, but any suggestions of brand? or kind?
(mural painted on polyflax canvas with acrylic and varnished with waterbase floor varnish)
Thank you!

wallpaper glue is fine.

btw, why did you coated it with floorwarnish??? it will get yellow intime and brittle also...

use glaze or satin acrylic medium...

The varnish I use is non-yellowing- it's the oil based stuff that yellows as I understand, anyway, it hasn't yellowed yet and I have things 20 years old with it on.
