When selecting edges (trim) pieces for the garage floor tiles, please pay attention to the material. The PVC edges only work with the PVC tiles. The polypropylene edges work only on the BlockTile garage floor tiles. In most installations, garage tile edges are used on the entrance of the garage only. Hence, selecting the proper garage tile edge is important. Please note that we make garage tile edges with loops and without loops. For a standard garage, we recommend you to start installation from the entrance of the garage. If you follow our recommendation, please select the edges with loops.
