Aqua patch is water-activated and uses a proprietary blend of organic additives that are environmentally friendly, safe, and non-toxic. It produces no hydrocarbon leaching or evaporation into the soil or atmosphere, and can be used in all types of weather – cold or warm, wet or dry. Water or moisture in the repair area is not a problem. Since Aqua patch is water-activated, water actually helps accelerate the bonding and hardening process. No tack coat is required, streamlining the repair process.
