So basically wait a week before re-coating, right?
It can be recoated before 6 hours if used without hardener. With hardener, the recoat time is a little fuzzy. The data sheet says dry to handle in 3 hours and recoat 3 hours to 4 days. With hardener, it doesn't have the caution about lifting of the previous coat, so not sure if that 3 hour to 4 day window is to be avoided.
