We've been in the process of refinishing our pool since end of September. We're finally ready to replaster (with River Rok) but I'm concerned about the weather here in Connecticut. The installation guidelines for River Rok say, "All materials and effected areas should remain above 50 degrees 24 hrs prior and 72 hrs after replacement". The forecast is for a high of 45 on the day (low of 31 for the following few days and only getting colder). Should I be worried or is it okay to finish this now? Thanks for your wisdom.
