But when asking how long does it take resin to dry, there are some general guidelines:
Many epoxy resins will be dry to the touch within 24 hours of mixing and pouring. It will take seven days for a full cure, but you can handle your project at this point if you are careful. It may scratch or dent (not ding) if you aren’t gentle enough. If you are using a slow-curing epoxy, allow it to sit for 48 to 72 hours to be touchable.
There are such things as quick-curing resins. These are usually polyurethane resins that can cure within minutes to an hour or two. Quick-curing resins are better suited for those already skilled in resin. In other words, these aren’t resins for beginners.
Polyester resins are generally touchable in about 12 hours. Silicone resins vary widely but are usually touchable twenty-four hours post-pouring.
