TL;DR
Artificial turf infill is the material brushed between turf blades. It helps blades stay upright, improves comfort, adds weight to reduce wrinkles and ripples, and can help protect the backing from UV exposure. Most lawns start around 1–2 pounds of infill per square foot, then need smaller top-ups over time in high-traffic and pet areas.
Quick Answer:
Infill keeps artificial grass looking fuller and feeling more natural by supporting the blades, adding cushion, and stabilizing the turf surface, and you may need to top it up occasionally as part of routine turf maintenance.
What is infill for artificial turf
Infill is the granular product placed between the blades of an artificial turf lawn to fill the open space and support the turf system.
Infill helps in a few practical ways:
✔ It supports turf blades so they maintain a more upright position.
✔ It adds cushioning so the surface feels more like natural grass underfoot.
✔ It adds weight (ballast) to help reduce wrinkles, buckles, and ripples.
✔ It can help protect the turf backing by reducing UV exposure over time.
📌Local note: Whether you live in San Diego, Las Vegas, Los Angeles, Santa Ana, or Phoenix, the most common infill questions are the same: what it is, why it matters, and how much you actually need.
What does infill do for turf maintenance?
Infill makes turf easier to maintain because it helps the lawn keep its shape and performance between cleanings.
Here’s what that looks like in real use:
➡️ Less matting: When infill levels are healthy, blades are more likely to stand up after brushing and foot traffic.
➡️ More consistent feel: Infill helps the turf feel less hard in frequently used areas.
➡️ Better stability: Added ballast helps reduce shifting and surface rippling.
➡️ More predictable upkeep: When infill drops, turf can mat faster and feel harder, especially in pet zones.
How much infill per square foot do you need for artificial grass?
A common starting guideline is 1–2 pounds of infill per square foot for many residential installations.
Your “Goldilocks” goal:
➡️ Too little infill: blades are less supported and can flatten faster.
➡️ Too much infill: infill can become visible between blades, which hurts the natural grass look.
How much will a 50-pound bag cover
A simple way to estimate coverage is:
👍 At 1 pound per square foot, a 50-pound bag covers about 50 square feet.
👍 At 2 pounds per square foot, a 50-pound bag covers about 25 square feet.
Practical tip you can highlight
💡 Tip: If you are only topping up (not redoing the whole yard), you will usually need less than the initial install amount, because you are filling in thinned-out areas rather than starting from scratch.
How often do you need to add infill to artificial grass?
Most homeowners do well by checking infill at least once a year and topping up only where it is thinning, especially in high-traffic lanes and pet areas.
Some maintenance guides suggest a 12–18 month top-up rhythm as a general baseline, but usage and climate can change that.
Signs you likely need an infill top-up
The clearest signs are:
➡️ Blades look flat shortly after brushing
➡️ Backing becomes more noticeable in worn areas
➡️ The turf feels harder in certain zones
➡️ High-traffic lanes look more “pressed down” than the rest of the lawn
➡️ Pet areas start holding odor longer than usual, even after rinsing
💡 Tip: Top up the “hot spots” first (pet runs, play areas, gates, and walk paths). That’s usually where infill drops fastest.
How do you put infill in turf without making a mess
The safest method is to apply infill in light layers and brush it in between passes so it settles below the blade tips.
Step-by-step: how to add infill to artificial grass
👉 1. Remove debris first so infill does not trap leaves or dirt.
👉 2. Brush the turf to lift blades and open the canopy.
👉 3. Apply infill in light passes using a drop spreader or careful hand application.
👉 4. Brush again to work infill down between blades (a power brush can speed this up on larger areas).
👉 6. Repeat in thin layers until the turf looks full and even.
Practical tip you can highlight
💡 Tip: Stop before infill becomes visible at the surface. The best look is when infill sits lower in the turf canopy and blades remain the most visible part of the lawn.
What is the best infill for artificial grass if you have pets?
For pet households, the best infill is usually the one that helps with odor control while still supporting blade structure and comfort.
TurFill is positioned as a pet-friendly infill option because it is designed to neutralize pet odor by breaking down ammonia and proteins in urine to address odor at the source rather than covering it with fragrance. It is also described as all-natural, non-toxic, and safe for kids and pets.
💡 Tip: Pet zones are the first places to show infill loss. If one area of the yard always smells worse than the rest, treat that as a “maintenance zone” and check infill depth there first.

Frequently Asked Questions
Is infill necessary for artificial grass?
• Infill is used in many turf systems because it helps support blades, adds cushioning, and stabilizes the surface, but the right approach depends on the turf product and how the space is used.
How much infill do I need for turf if I am only topping up?
• Top-ups usually require less than initial installation because you are refilling thin areas rather than building the full infill layer across the entire yard. A yearly inspection helps you target only the spots that need it.
How much infill for artificial turf in high-traffic areas?
• High-traffic areas often need closer monitoring and more frequent top-ups, because infill shifts and compacts faster where people and pets use the lawn most.
How do you get rid of wrinkles in artificial grass?
• Infill can help reduce wrinkles and ripples by adding ballast weight and improving surface stability, but persistent ripples may point to installation or base issues that need a professional look.
What is “synthetic pitch infill top-up” and is it different from a home lawn?
• Sports and synthetic pitches often follow different infill specifications than residential lawns, so the best practice is to follow the turf and infill manufacturer guidance for that specific system.
