A Complete Guide to Evaporative Cooling Infill for Synthetic Turf

Ideal Settings and Uses for Temperature-Reducing Infill

Application Guidelines and Quantity Planning




Standard silica sand simply holds heat absorbed from the sun and radiates it back upward, making turf surfaces dangerously warm. Moisture-activated infill actively works against heat buildup by storing water and releasing it through evaporation, effectively pulling thermal energy away from the turf surface and delivering a noticeably cooler feel underfoot during the hottest parts of the day.
During dry summer periods, a brief, light watering every two to three days is typically sufficient to keep the evaporative cooling process active. Natural rainfall will recharge the particles on its own, meaning upkeep during wetter months across the Bay Area is minimal and effortless.
Yes, this type of cooling infill is non-toxic and completely safe for pets. It is particularly well-suited to dog runs because it helps keep paw pads cooler on hot days, supports good drainage, and can help manage odor — all qualities that matter for a pet-friendly outdoor turf environment.
In most cases, yes. You can add HydroChill Turf Infill to an existing lawn by using a drop spreader and working the granules down into the turf fibers with a power broom. Our team can advise on proper application rates for retrofit projects.
Using the standard rate of three to four pounds per square foot, a 500-square-foot area will require somewhere between 1,500 and 2,000 pounds of infill. Simply bring your measurements to our San Jose warehouse and we will calculate the exact quantity for you on the spot, so there are no surprises or shortfalls mid-project.
