Sanding prior to expoy repair ,maximum time / days between sanding and actually starting to laminate

[Restoration man]

as we all know sanding is a pain but very necessary, ive got a lot sanding to do but can only do it on certain days and I have time restraints as well due to regulations at the yard im in , so sanding and doing the actual epoxy work on the same day is impossible, what’s the maximum time/days you would want to leave parts of the inside of hull I’ve already sanded before actually doing the laminating ? Obviously I will wipe with acetone on the day of laminating, the places that have been sanded are inside on the boat so will be kept clean and dry between sanding and laminating, this is glass on glass no wood etc and I will be using epoxy
Thanks Nick

That being said and a wiping of acetone prior to glassing I see no time restraint withing a reasonable time frame.
Weeks to a couple of months max I guess.
