Where a field seam makes a radical bend (turns up a wall or down over a perimeter edge), a 15.24cms wide by 30.48cms long piece of Uncured Flashing with Tape should be fixed over the seam. Round the corners of the Uncured Flashing with Tape to prevent accidental peeling. Following standard flashing procedures, install the flashing so that half of the flashing is on either side of the radical bend.
