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.

    1. 60g or 200g is the amount of resin in the bottle. g represents grams so therefore one is a 60 grams bottle and the other is a 200 grams bottle

  1. Hey so my resin seems to be done and it’s been about 10 hours, it’s amazing clear cast and on the edges if I put hard enough it kinda moves but other than that it seems sturdy

    1. Hi Kaydence, it sounds like you need to give it more time. The amazing clear cast resin needs 24 hours for a 90 percent cure. Allow 7 days for a full cure.

  2. Hi there – is it okay to pour additional layers of resin on a layer that has been curing for 24 hrs or more, without sanding the cured layer?

    Due to my schedule I have been creating some pieces the second pour happening a full day later, or sometimes picking up projects weeks later. The final pieces do not seem to have issues, although now all the info I have found online says sanding is a necessity to do this.

    Thank you!

    1. I almost insist on this especially if it’s a board you really care about. If you do a netting with the resin, sand that down a bit and then re-laminate and sand again. You can be assured the repair will last much longer.

  3. Hi! I used the Deep Pour Casting Resin for the first time 24 hours ago and I loved how easily it mixed with so few bubbles while stirring and was so crystal clear! This is my first time working with a slow curing resin and it’s still in the “gooey” state which I expected but my question is: Do I need it to cure the full 48 hours before I can do a second layer or can a second layer be poured while it’s in this stage of curing?
