1 Place the tiles on a soft surface and sand any markings off of the rough side of the tile. Wipe with damp cloth.
2 Sand edges of the tile to get rid of chipping and sharp edges. Wipe with a damp cloth.
3 Arrange two brackets on one end of each long tile so that the small part of the bracket is holding the tile.
4 Tighten the brackets to the long tiles. Do not over-tighten, but make sure the brackets are very firmly gripping the tile.
5 Slide the brackets attached to the long tiles firmly onto place on the short tile. Tighten the brackets to the short tile. Do not over-tighten but make sure the brackets are firmly in place.
