Spread a thin layer of sand evenly over the tops of the pavers.
Sweep the sand into all the spaces between your pavers, starting on one side and working your way toward the other. Use the broom to push the sand between the paving stones, sweeping in all directions until the sand is relatively compacted.
Sweep any excess sand off of the surface of your pavers. Use a light touch, in order to avoid disturbing the sand in between the pavers.
Turn on your hose and set it to low. Using a spray nozzle, spray the pavers with water to help pack down the sand in between the pavers and wash any remaining sand from the surface. Allow the pavers and sand to dry completely.
Start over by pouring more sand over the pavers and repeat the process. This will ensure all areas between the stones are filled with sand.
