What is the working temperature for this product? And does humidity affect the mixture?

Epoxy resins are affected by temperature and humidity – so the cooler and drier your work area is – the better the results. Warmer temperatures lead to faster curing and a too-humid environment may lead to moisture entering the mixture. Ideal conditions are room temperature of about 75 degrees (with a maximum of 90 degrees) and humidity levels of 85% or below.
