Pour the crushed stone into the area you are going to create your path or patio.
Spread the stone out with the back of the garden rack. it does not have to be perfectly level.
Drag the 2-by-4 across the surface of the stone. This will give you a flattened consistent surface. Hold the 2-by-4 in the middle with both hands 12 inches apart. Slowly drag the 2-by-4 over the stone.
Check the stone for level. Areas that are more than 1/2 inch high need to be leveled. After you have completed this, use the power tamper to pack all of the stone. This device has a large metal plate at the bottom and vibrates. It will crush some of the stone and move the smaller particles into the surface.
