What is the best way to cut the 1/2" tile? I want to make a nice fit around the walls in the room.

The best way to cut our 1/2" Rubber Gym Tiles is a sharp utility knife and a straight edge. Multiple scores with the knife a typically necessary, but this is the best way to cut the tiles and keep a nice clean look. You can use a jigsaw on low speed with silicone or water, and this too can effectively cut the tiles with ease.
