The best temperatures to apply Hemp Shield are over 50F and under 90F. The dry time will vary depending on the relative humidity. You need the water portion to evaporate for a cure and this can be 2 hours or longer depending on humidity. Old painters have a saying: When applying wood paint just follow the sun. So start off in the morning on an area as it comes into the shade. Work your way around the house following the sun. This will give you a warm dry
surface to paint and a log dry time before the sun hit the surface again.
