How pet turf odors form

Urine breaks down into ammonia. If the turf system drains poorly or the infill traps moisture, bacteria thrive and odors linger. Good infill manages liquids, reduces bacterial growth, and limits ammonia off gassing.

Top infill options for odor control

Zeolite infill

Zeolite is a porous mineral with natural ion exchange that captures ammonium from urine. Rain or a hose rinse helps flush and refresh the media. It is effective as a targeted odor control layer.

  • Pros: Strong ammonia capture, pet safe, easy to add as a topper later.
  • Watchouts: Can hold some moisture, may need periodic recharge rinses, do not over apply to the point of matting.
  • Best for: Home yards, targeted pee zones, dry or moderate climates.

Antimicrobial coated sand

Rounded silica sand with an antimicrobial coating provides ballast and drainage while inhibiting odor causing bacterial growth. It stays stable under traffic and grooms cleanly.

  • Pros: Consistent drainage, low dust when quality coated, durable under heavy use.
  • Watchouts: Higher material cost than plain sand, still relies on proper base drainage.
  • Best for: Multi dog homes, kennels, dog daycares, humid climates.

Other infills compared

  • Plain silica sand: Stable and affordable but offers little odor control on its own.
  • TPE or other elastomers: Inert and clean but do not neutralize urine.
  • Cork or organic infills: Lightweight and cooler surface feel, can absorb moisture and require vigilant upkeep with heavy pet use.

How to choose for your yard or facility

  • Pet load and traffic: More dogs and tight potty zones benefit from antimicrobial coated sand or a coated sand base with zeolite in hotspots.
  • Climate: Humid areas favor antimicrobial coated sand. Arid areas do well with zeolite as a topper or blend.
  • Drainage and base: A free draining base is non negotiable. Fix drainage before upgrading infill.
  • Maintenance style: If you prefer simple rinses, lean coated sand. If you will spot treat and top up, zeolite works well.
  • Budget: Zeolite can be a cost efficient topper. Coated sand is a higher upfront cost with steady performance.

Recommended depths and mixes

  • Backyard pets: 2.0 to 3.0 lbs per sq ft antimicrobial coated sand as primary infill. Add 0.5 to 1.5 lbs per sq ft zeolite in potty lanes and corners.
  • Heavy use kennels or daycares: 3.0 to 4.0 lbs per sq ft antimicrobial coated sand across the field. Add targeted zeolite where dogs consistently urinate.
  • Zeolite only approach: 1.0 to 2.5 lbs per sq ft as a topper over a stable base infill. Plan on regular rinse and periodic enzyme treatment.

Always follow your turf system specification for total infill weight and blade exposure. Keep 0.5 to 0.75 inches of blade above the infill line for natural look and fast drainage.

Installation steps that keep odors in check

Prep base and drainage

  • Grade for about 1 to 2 percent slope away from structures.
  • Install a compacted, open graded base that drains quickly. Add perimeter edging and geotextile where specified.
  • Use subsurface drains in confined areas if water lingers.

Apply infill correctly

  • Spread infill in light lifts with a drop spreader.
  • Power broom between lifts until the target weight is reached.
  • Keep infill out of seams and around edges. Groom to even depth.

Activate odor control

  • Rinse the surface after install to settle dust and hydrate zeolite.
  • For the first week in high use areas, quick rinse after peak potty times.

Simple maintenance that prevents smell

  • Daily to weekly: Pick up solids promptly. Quick hose rinse in potty zones.
  • Weekly: Apply an enzyme based urine neutralizer in high traffic areas, then rinse through.
  • Monthly or as needed: Deep flush with a garden hose for 5 to 10 minutes per 100 sq ft to push residues past the base.
  • Grooming: Cross brush to lift fibers and keep infill evenly distributed.
  • Cleaners: Use pet safe enzyme products. Avoid harsh chlorine that can affect backing and landscape around the turf.

Troubleshooting stubborn odors

  • Hotspots: Add 0.5 to 1.0 lb per sq ft of zeolite to the zone and groom in, then rinse.
  • Poor drainage: Relief cut and rework the base or add drains. Infill cannot fix a saturated base.
  • Infill low: Weigh a test patch. If light, top up coated sand to spec.
  • Deep clean: Enzyme soak, let dwell per label, then thorough flush.

Safety and pet wellness

  • Select non toxic, low dust infills from reputable sources.
  • Wear eye and dust protection during install. Keep bags dry and closed.
  • Rinse the surface before first play to remove any handling dust.

Cost snapshot

  • Zeolite: About $15 to $25 per 50 lb bag. Typical 1.0 to 2.5 lbs per sq ft as a topper.
  • Antimicrobial coated sand: About $25 to $40 per 50 lb bag. Typical 2.0 to 4.0 lbs per sq ft as primary infill.
  • Example 500 sq ft yard: Roughly $200 to $600 in infill, depending on mix and target weights.

FusionTurf recommendation

For most homes, use antimicrobial coated sand as the primary infill for stable drainage and consistent odor control. Add zeolite where dogs prefer to go for extra punch. For kennels or high density yards, load coated sand at the top of the spec and schedule enzyme treatments. If your base does not drain, fix it first. That is the only way to win long term.
