Optimum dry time between coats is two to six hours, not to exceed 12 hours. The previous coat should not be wet or too tacky; if there is no transfer of the coating to a gloved finger it is safe to apply an additional coat. If 12 hours or more have lapsed, wait at least 24 hours, and lightly scuff the surface with 80-100 grit sandpaper to break the glaze of the coating and provide a profile for inter-coat adhesion. This 12-hour time frame is decreased in higher humidity areas. It is recommend to wear spiked shoes when applying additional coats to your floor to prevent footprints. Even though the coating is dry to the touch and ready for additional coats, it is not completely cured and may potentially leave footprints if walked on.
