To set the stones into the base of stone dust, run the vibrating compactor over the entire stone surface. The compactor will compress the stone into the dust, stabilizing the sheets.
If a fan design is laid, trim the sharp edge. First, using a marking pen or pencil, draw the cut line on the stone. Then rent a portable concrete cut-off saw (about $50 per day) to cut the line where drawn.
Make certain the saw blade cuts entirely through the stones. Now, take the snips and cut the cast-in grid cord to remove the excess stones on the outside of the perimeter.
Safety Tip: Using a portable concrete cut-off saw is dangerous. Use caution and follow the directions provided by the rental center. Wear heavy boots and safety glasses.
To secure the stone perimeter in place, mix up some Type S mortar and trowel an outside edge frame around the perimeter. This will keep the stones from slipping and stabilize the area.
