ScotchBlue PROSharp Painter's Tape provides our sharpest paint lines yet thanks to our new Edge-Lock+ technology. Designed to handle both indoor and outdoor projects, it provides 2X better hold than our original Edge-Lock technology, sealing out paint to leave consistently sharp lines across multiple paint types and finishes. Whether you're protecting drywall, trim, baseboards, painted walls, wood, tile flooring, or glass windows, this versatile painting tape can stay on surfaces for up to 21 days and then remove easily without leaving any sticky residue behind, even after exposure to the sun. ScotchBlue PROSharp Painters Tape can be used in a wide range of outdoor temperatures, from as low as 40F up to as high as 100F. Its multi-layer construction and premium smooth backing provides enhanced resistance to tears or slivering and promotes even adhesion to prevent paint seepage, reducing the need for touch-ups and repaints.
