FrogTape is a medium tack painter's masking tape for use on the following surfaces: cured painted walls, wood panelling, glass and metal. FrogTape can be removed cleanly from most surfaces for up to 21 days (seven days in direct sunlight). PaintBlock technology sets FrogTape apart from other painter's tapes. PaintBlock is a super-absorbent polymer that reacts with the water in paint to create a micro-barrier in a flash. The result: no colour bleeding and sharp colour edges.
