Art Mechanique Paper Sealant has been hand picked by ICE Resin creator Susan Lenart Kazmer, who uses it exclusively in her own collage work. When applied to paper that is destined to go under ICE Resin, it will maintain its opacity, instead of becoming transparent, as paper does under ICE Resin. You probably love, as we do, the transparent effect ICE Resin has on paper. The use of Paper Sealer is for those special cases where you want to keep very dark, graphic lines in your collage work, or when using actual photographs, which can have a mottled look under resin because of uneven emulsion. Either way, it's good to have around the studio!.
