hello an adhesion test is best done by painting a small 1 ft by 1 ft area then impregnate a strip of polyester mesh fabric into the area.  let dry and coat over the tape leaving about 4-5 inches that has not been coated exposed.  Then once that is dry pull up on the fabric if the coating lifts up then the adhesion has failed. We see on silicone and PVC roofs.

Thank you
