88 years to completely cure if conditions are ideal.
Best thing I've come across is this curing solution/epoxy primer in
one. It's by some chemical company in Philly and I can't remember the name
and I gave the last gallon to my brother-in-law. Applied after final
finishing, it's basically a poly-styrene and polymer mix that totally seals
the concrete. I have a friend who never got around to epoxying the floor
and the curing coat is still going strong a year later - except for the gas
spill. :-) When you want to epoxy, you wash the floor - no acid-etch or
anything - and put on a new coat of the cure/primer and then epoxy on
that. The chemical bond between the cure/primer and concrete is greater
than between epoxy and concrete, as well as the bond between the
cure/primer and epoxy. Good stuff.
