Norton Foam Masking Tape 13 mm x 50 m (1/2" x 54.6 yds) White. Norton foam masking tapes are easy-to-use, time-saving products to mask door jambs and other apertures like hood and deck lid openings that need to be sealed during the painting process. Foam masking tape produces a soft edge, rather than a hard paint line, so rework is eliminated and productivity is increased. To prevent paint build up at the adhesive edge, be careful in closing the moving part not to roll the foam and expose the adhesive. If the adhesive is exposed, the foam tape must be removed and repositioned so the adhesive is not exposed. FOR REMOVAL: Lift one end of the foam about an inch from the surface then stretch the foam tape parallel to the surface to ensure clean removal. (Do not remove foam at a 90 degree angle as this may cause adhesive transfer). 70735
