Ty, I copied this from Klass Kote's FAQ page of their website:
10. Are there minimum and maximum temperatures required to apply Klass Kote Epoxy Paints?
We do not recommend using (applying) the product on substrates below 50° F or above 120° F - likewise for ambient (air) temperatures. For optimum results, apply to substrates, and store the product between 50-80° F. Humidity can slow the curing processes, but in most cases, Klass Kote Epoxy Paints are very forgiving. For best results, use product below 70% humidity.
