HOW TO CHOOSE ARTIFICIAL TURF INFILL

Raw silica sand tends to have microscopic jagged edges. This is usually fine if the area is lightly used. However if the turf will see a lot of foot traffic, this could cause the sand to wear down the artificial grass blades over time. Sand infill can also be more abrasive if people were to fall and slide on the turf.
