Does humidity effect the epoxy curing process?
Bar and Table Top Epoxy -
As long as the temperature is above 75 degrees, the epoxy will cure just fine. Humidity is not an issue. The warmer the temperature the better. Some thermostats are not 100% accurate so it's always better to put the temperature a few degrees higher than 75 degrees to ensure that it cures correctly.
Deep Pour Epoxy -
You will want the humidity to be 50% or lower when using the Deep Pour Epoxy to maintain ultimate clarity while pouring and curing.
