Make sure there are no large creases in your turf or it will effect the roll of the ball. Small creases will disappear when sand is applied. Sand filling the green will make the turf fibers stand straight up and allow the balls to run on top of the turf. Also, the sand will absorb the impact of shots chipped to the green.

Before spreading the sand, you will need to separate the fibers to allow for easy application and filling. Brush against the grain of the turf with a push broom. You may need to brush it several times to get the fibers prepared for sand filling.

Once you are ready to start filling the green with sand, keep the green completely dry. If the sand or green get wet during this process the sand will clump together and make it difficult for the sand to get between the fiber of the turf.

Fill the drop spreader with sand and start spreading the sand across the top of the green. Start spreading the sand in the middle of the green and working your way to the outside edges. When you have covered the whole green with sand, use a your push broom against the grain of the green to push the sand into the fiber. Be sure not to apply too much sand at one time before brushing. A good rule of thumb is to spread 50 pounds of sand over an entire 12' X 24' area and then brush it in before continuing. You will have to be aggressive as you brush in all the sand to make sure you are getting all sand between the fibers. Your main goal is to get all the fibers of the turf to stand completely vertical. Too much sand can bury the fibers and may cause areas to have more sand than others. Work the area over with your broom until you have evened out all the sand.

Continue the sand filling process until you have no more than 1/8" of the fiber showing on the putting green. Use the bags of black sand last. The black sand is for esthetics or visual purposes only. As it covers the white sand it will make the putting green fibers look denser and deeper. When you feel like you are done try a few putts on your new green. If you putt the entire length and the entire width with no significant hop or bounce, then the ball is rolling true and you are finished. If the ball does not roll true, continue filling the green with sand and brushing it in until you achieve a true putt.
