A great value for building containment or sealing door and window openings. The double-sided tape has a painters tape side for sticking to walls and trim, but is gentle on paint and removed. The other side has a duct tape side to grip the plastic and not allow a breach in your containment.Our double-faced containment tape is 150% longer than our competitors rolls -- 90 feet (30 yards) compared to 60 feet (20 yards). This means less waste from the end of the rolls and less trips to the truck.TIPS for use:When tearing the tape (dont use scissors or a knife), stretch it a little to make a tab -- making it easy to grab to peel off the backing.When removing the tape, use a slow pull, rather than quickly yanking it off the wall. This will help it release better from the painted surfaces.Roll: 2 inches wide x 30 yards
