Why do I need infill?

Artificial grass infill is used to help weigh the artificial turf down and cause the synthetic grass blades to stand up straight, creating a more realistic look that is much less matted than without infill.  Also, infill adds another layer of “cushion” to the turf backing improving durability.

How much infill is recommended?

Proper infill installation is critical to maintaining your artificial grass system. It is recommended to use 1-3 lbs. per sq. ft., depending on your application type.

Which infill should I use for my artificial grass application?

Landscape application: For the budget-conscious, silica sand infill can be used for a general front or backyard installation where pets and children are not present. With children and/or pets, a more specialized infill is recommended.

Pet application: Smart Fill® is a round-shaped green-coated sand that reduces fluid absorption and improves drainage. It’s integrated with anti-microbial that helps control the growth of bacteria, mold, and odors. Paired with one of our Microban anti-microbial artificial grass, adding another layer of antimicrobial in the infill will help with odor control.

Putting application: #60 grit silica sand is recommended for most texturized putting green applications. This sand is finer and will fill in between putting green blades better than the coarser sand used in landscape applications.

Playground application: Smart Fill® is recommended because of its integrated anti-microbial qualities. The added level of protection can offer peace of mind as children are tumbling and rolling across the lawn.

Athletic application: Indoor fitness areas using Smart Turf Multi-Sport do not require infill. When Multi-Sport is used in an outdoor fitness application, Smart Fill® is recommended because of the expansion and contraction of the artificial turf in the sun.

Artificial Grass Infill Power Broom

When will I need to replace the infill?

Proper installation of the infill is important to ensure it’s positioned correctly. The infill should be spread evenly throughout the artificial grass and then brushed or broomed into the turf fiber blades. A power broom is recommended to brush up turf fibers and let the infill work down in between the turf blades. Finally, water the entire area evenly with a hose to settle the material.

When using Silica Sand or Smart Fill, we recommend replenishing it every 5 to 7 years. The rule of thumb is to let the artificial grass blades tell you. If they look droopy and limp, more than likely you may need to refresh your infill.

Overall, please note that each application can be unique, and these are general guidelines however Infill is an integral part of any artificial turf system and plays an important role in the success of an artificial grass lawn. A properly installed artificial turf system can be enjoyed for years to come.
