3M ScotchBlue™ Ultra Sharp Lines Painter’s Tape is a versatile multi-surface painter’s tape with Advanced Edge-Lock™ Technology that seals out paint to deliver ultra sharp paint lines. This innovative poly-tape is different than standard 3M paper painter’s tapes, it conforms to curves, tears straight for fast cornering, and best of all, removes from the surface without tearing or slivering. Great for protecting painted walls, wood trim, tile floors, or glass windows as you prep for a painting project. Tape removes easily after up to 28 days leaving no damage or sticky residue. Core Size: 3"; Dispenser Included: No; Adhesive Material: Acrylic; Backing Material: Crepe Paper.
