cure

Due to damage and rot, as well as discovering that the brick veneer has an inadequate footing under it, I am removing a 16 foot section of an exterior wall, pouring a footer and then framing a new wall which will be finished ultimately with siding. I'll have a temporary support wall holding up...

Just getting ready to pour a 30 x 50 gargage floor, and the contractor recommends I apply a curing agent rather than try to keep it wet for a week. Does anyone know approximately how much I'll need for a 1500 sf slab, and what I can expect to pay for it? Any other advise is also appreciated.
