FrogTape is a special painting tape that is treated with PaintBlock technology for professional results on baseboards, crown moldings, door/window frames and much more. PaintBlock seals the tape edges for sharp lines. This super-absorbent polymer reacts with latex paint and instantly gels to form a micro-barrier to seal the edges of the tape and prevent tape bleed. Medium-adhesion painters tape is designed for use on cured painted walls, wood trim, glass and metal. Multisurface FrogTape will remove cleanly from most surfaces for up to 21 days and seven days in direct sunlight.
