Ball roll distance on rolled plots was 5 to 11 inches farther than nonrolled plots on a USGA sand green. As the study progressed, a general increase in putting green speed was observed. On a native soil green, roll was also greater for the rolled treatment. Ball roll was 5 to 13 inches farther on the rolled plots.
After the first sand application has gone away and can no longer be seen, then you can do a 2nd sanding if needed. You need about 8 yards of sand to cover a high school size infield. Dry or barely moist sand spreads better and is easier to work with than damp or wet sand.
