Once Epotec has been mixed and applied correctly it will cure in about 5 – 6 hours, providing the temperature remains about 15 – 20 C. During this curing time, rain and condensation needs to be kept off. If it gets wet within this time frame, a whitish bloom may form on the surface. This may be aesthetically unacceptable especially on the last coat, though it will not affect the curing or performance of the Epotec. It may be left and will usually disappear after 1 – 2 months of usage. Otherwise it may be sanded off and recoated.
