Sweep Polymeric Sand into Joints

What happens here

Using a stiff-bristled push broom, sweep the polymeric sand across the paver surface. The video clearly shows the action of pushing and pulling the broom repeatedly over the pavers to work the sand into the joints. Sweep in multiple directions, including diagonally across the paver lines, to ensure that the sand penetrates deeply and fills all crevices. Continue this process until all paver joints appear completely filled and compact, with no voids.

Goal: Fill all paver joints completely with polymeric sand.
