Meeting the proper infill requirements for the turf system you have purchased is extremely important to the appearance, performance, and life span of your artificial grass. Please ask your AGL product specialist for infill requirements. There are many different types of appropriate infill that can be used. Options include: Acrylic Coated Sand, Zeolite, Silica Sand or Crumb Rubber. We recommend using a drop spreader to evenly disperse the proper amount of infill.
