Why infill matters when you brush
Brushing lifts fibers and relevels the surface. Infill is what keeps those fibers upright, stabilizes the base, cushions footfall, and helps manage temperature and drainage. When infill is right, the lawn rebounds fast, looks crisp, and performs consistently.
What infill actually does
- Support: Holds blades vertical for a natural look and safer footing.
- Ballast: Adds weight that reduces ripples and movement.
- Cushion: Adds shock absorption for play and falls.
- Drainage and cleanliness: Keeps the profile open so water and rinses move through.
Does brushing remove infill?
Normal brushing redistributes infill more than it removes it. Aggressive brushing, high traffic lanes, slopes, and heavy rain can move infill and create low areas. Use a stiff nylon broom or a power broom with light, even passes on a dry surface.
How to tell if you need more infill
- Visual lean or matting that returns quickly after brushing.
- Exposed thatch or backing in traffic lanes or around corners.
- Footprints that do not rebound within a few minutes.
- Divots, ripples, or uneven texture you can see across the grain.
Quick checks that work
- Depth check: Part the fibers and look for consistent infill sitting below the tips. You should see infill supporting the thatch without burying the blades. Follow your turf spec for target depth.
- Weight check: Compare current infill weight to your product spec. Typical landscape systems run about 1.0 to 3.0 pounds per square foot. Pet, play, and sport areas often need more. Always verify the exact requirement for your model and pile height.
How to top up infill the right way
- Prep the surface: Brush the turf dry to lift fibers and reveal low spots.
- Inspect: Check seams, edges, and high traffic lanes first.
- Apply infill: Use a drop spreader or hand shaker for even coverage. Start light.
- Work it in: Brush against the grain, then with the grain, to settle material into the thatch.
- Measure and repeat: Recheck depth or weight. Add small amounts until you hit spec.
- Lock it in: Lightly water to settle dust and help infill nest. Let it dry, then final brush.
Choosing the right infill
- Silica sand: Proven, economical, steady performance for most landscape installs.
- Coated sand: Adds antimicrobial benefits and cooler surface temps. Great for pets and high use zones.
- Odor control blends: Zeolite and coated options help neutralize pet ammonia when used as part of a maintenance plan.
- Performance elastomers: TPE or EPDM for higher impact play or training areas.
Match infill to pile height, use case, and your turf manufacturer’s spec. Consistency beats volume. Aim for even support across the whole surface.
Maintenance cadence that works
- Light brush: Monthly for homes, weekly for high traffic areas.
- Spot checks: After storms, parties, practices, or heavy pet activity.
- Depth or weight verify: Quarterly for homes, monthly for facilities.
Mistakes to avoid
- Overfilling: Buries blades and slows drainage. Add in small passes.
- Underfilling: Causes matting, fiber fatigue, and uneven wear.
- Wrong tools: Skip metal bristles. Use nylon brooms or a calibrated power broom.
- Wet brushing: Moist infill clumps and streaks. Work dry for accuracy.
- Beach or masonry sand: Often too fine or dusty. Use purpose designed infill.
Climate and use factors
- Slopes and edges: Infill migrates more on grades and at hard transitions. Inspect often.
- Heavy rain and freeze cycles: Can shift infill. Relevel after weather swings.
- Pets and play: Higher activity compresses infill faster. Plan for periodic top ups.
When to call a pro
- Widespread matting or low spots across zones.
- Visible backing over large areas or seam exposure.
- Play and sport surfaces that need verified fall height or performance specs.
