Prior to applying Perma-Zyme, be sure to consider weather factors such as precipitation and temperature.
We recommend applying Perma-Zyme when there is no rain in the forecast for at least three consecutive days (72 hours). If an unexpected rainstorm occurs within the three-day timeframe and the roadway softens, rewet the surface and recompact it (see TROUBLESHOOTING for more details). In the event of a very large rainstorm that completely compromises the surface, contact your sales representative.
Temperature is an important factor when applying Perma-Zyme. If the temperature is too cold, Perma-Zyme will not fully cure and thus will not harden to the desired strength. If the temperature is too hot, the heat will destroy the enzymes, and the product will not work. We recommend applying Perma-Zyme when temperatures will remain between 40°F and 115°F for at least 72 hours after application. Curing may take longer in cool temperatures.
