RE: Epoxy Finishing Resin?
After 24 hours I would expect that the epoxy resin should be tack free. I don't use anything but West Systems epoxy on my boats so I'm not familiar with the mix ration on the product you have. Sounds like you may have used the wrong resin to catalyst ratio. Let it sit for several days and see if it eventually hardens. Patience will sometimes cure poor mix issues.
