Hi,
I am using Dibond panels for my acrylic paintings. I usually sandpaper the polyester coating and then clean it with isopropyl alcohol before applying some acrylic gesso on top of it… Both the panel sides are covered with a poyester coating. One side is glossy, the other is mate. Can I use any of them? Or is one of them better for adhesion? Thank you.
Best regards,
Thomas Ehretsmann
Often times manufacturers coat both sides of ACM with a polyester coating. One may have a matte finish while the other is gloss. In this case either side can be used to apply a suitable primer for painting after the coating has been lightly abraded to provide more surface area for adhesion of the primer.
