Hey. I'm not 100% on the curing time but really just playing that by ear at the moment. The grinding process on the top is complete now and that proxess was useful in order to gauge the state of curing. Really messy job but was able to get it within a few mm across the surface. I plan to pour it toward this weekend which should be over three weeks since it was poured for it to cure so my hope is that will be sufficient. Once the epoxy is on top my hope is that any remaining drying will be allowed for by the sides and underneath that will still be open to the air. I'm aware I'm experimenting here though, so it could prove to be an issue, but ill give it a bash to see how it goes. One thing I'm certain of at this point is the strength is there, even with a diamond cup on the grinder I was barely able to grind away the top, slow going. Whether that means a lot in relation to off gasing is beyond my knowledge to be honest
