King StarBoard Plastics can be bent to form a large radius or a very tight radius. Begin by using a heat gun to apply heat evenly to the piece of StarBoard you want to bend. Don't hover too long in one place, and take care to keep the heat gun 8-12" away from the surface. If you get too close, the heat will scorch the surface. While heating the StarBoard, bend it slowly to shape it around a large radius. Because the StarBoard has a tendency to relax back to its original position, you may need to over-bend it slightly. Continue heating and bending until you form the desired radius. Clamp the piece in place until it cools. To avoid damaging the surface, use shims under the clamps.
