How long do you let resin sit after mixing?
Cure time refers to the amount of time it takes for the resin mixture to totally finish its chemical reaction and become its hardest state. The ArtResin epoxy resin cure time is 24 hours (hard cure), however you can touch the surface after about 8 hours without it feeling sticky. It reaches its full cure at 72 hours.
