How each infill works
Zeolite: odor control and moisture management
Zeolite is a porous mineral that adsorbs ammonium from pet urine, reducing smell at the source. It holds moisture and releases it as the turf dries. Zeolite supports a cleaner surface but does not replace regular rinsing.
Coated silica sand: ballast, fiber support, and clean handling
Coated silica sand adds weight that stabilizes the turf, helps blades stand up, and resists matting from paws and play. Quality coatings reduce dust and improve cleanliness. Some coatings include antimicrobial features for added hygiene. Light colored sand can moderate surface temperature compared to dark infills.
Best practice: combine them
- Primary odor control: zeolite at roughly 30 to 50 percent of total infill by weight, concentrated in pet zones.
- Primary stability: coated silica sand at roughly 50 to 70 percent of total infill by weight for ballast and fiber support.
Quick recipe by pile height
- Pile up to 1 inch: total 1.5 to 2.0 lb per sq ft, split about 0.5 to 0.75 lb zeolite + 1.0 to 1.25 lb coated sand.
- Pile 1 to 1.5 inches: total 2.0 to 3.0 lb per sq ft, split about 0.75 to 1.25 lb zeolite + 1.25 to 1.75 lb coated sand.
- Pile over 1.5 inches or high traffic kennels: total 3.0 to 3.5 lb per sq ft, split about 1.0 to 1.5 lb zeolite + 2.0 to 2.5 lb coated sand.
Always verify against your turf specification and local conditions.
When to adjust the mix
Increase zeolite when
- Multiple dogs use the same small area.
- Shade or covered patios slow drying and limit natural rinsing.
- You want extra odor insurance for entrances and play zones.
Increase coated silica sand when
- Wind, slopes, or edges need more weight for stability.
- Large breeds, heavy play, or agility training increase wear.
- Taller pile heights need added fiber support.
Drainage and base fundamentals
Even the best infill cannot fix poor drainage. Build a free draining base and grade away from structures.
- Excavate and compact 3 to 4 inches of clean, angular base rock such as 3/8 inch minus or similar.
- Use a permeable geotextile if soil and base need separation.
- Select turf with a punched or fully permeable backing that fits local rainfall.
- Only use pads or drainage layers that are rated for high flow.
Installation tips that matter
- Pre broom to open fibers and stand the pile upright.
- Apply infill in two or three light lifts for even coverage.
- Power broom between lifts to settle and distribute infill.
- Lightly water after install to seat the system and reduce dust.
- Recheck coverage after one month and top off any low spots.
Maintenance for odor free performance
- Rinse urine areas 2 to 3 times per week in warm seasons. Daily for kennels and heavy use.
- Use a turf safe enzyme or oxidizing cleaner monthly to break down organics.
- Allow full dry cycles after rinsing. Drying helps zeolite maintain adsorption capacity.
- Spot refresh zeolite annually in heavy use zones. Plan a broader top up every 2 to 3 years as needed.
Safety and health considerations
- Choose washed, rounded, low dust coated sands for clean handling.
- Prioritize non toxic coatings and antimicrobial options where hygiene matters.
- Wear eye protection and a dust mask during installation.
Costs and lifecycle
- Coated silica sand is typically the lowest cost per pound and provides long term ballast.
- Zeolite costs more per pound and may need periodic top ups in urine hot spots.
- A balanced mix reduces total zeolite required while keeping odors controlled, which lowers long term cost.
Common mistakes to avoid
- Using too little infill, which leads to matting and faster wear.
- Relying on infill alone for odor control without rinsing and cleaners.
- Skipping a proper base or installing over soil that holds water.
- Dumping infill in one pass instead of building in lifts with brooming between applications.
Quick calculator
For 300 sq ft of 1.25 inch pet turf at medium traffic, target about 750 pounds total infill. Use roughly 300 pounds zeolite and 450 pounds coated silica sand. Always validate against your turf specification.
