I have tried a few different masks. Frisket, rice tape, low tack blue vinyl, and paper with spray adhesive. All but the vinyl, I used on art paper. Which of course pulls up paper if there isn’t paint on it. Even with paint on it, all of the masking will pull up some paint, and sometimes paper too, on the art paper. On a pre-primed,with acrylic paint, art board, the vinyl masking and rice tape would not pull up the primer, but occasionally(not much) would pull up paint I had sprayed then masked over. Especially CI burnt umber. how do you keep masking from pulling up paint? Should I spray an intercoat if I want to mask an area I have already painted? If so would Createx 4030 work? As I already have some.
