Hi Maryann,
You'll be right to put it on.

Maryann, what are your concerns? Are you worried that applying more finish could prevent the first coat from completely hardening?

As long as you can apply the second application with no trouble of your brush or spatula sticking the first one, you're fine to go ahead with it.

How long has it been drying for maybe you have to mix it better and equal parts. Just apply over top you will be fine

You can add an additional application any time after the first. A couple hours or a couple days. The less well set the first is, however, the more careful you've got to be in particular if you're applying with a spatula. You don't want to dent/cave, etc., the first. A little tackiness is of no concern.

Maryann, I thought that might have been your concern from reading earlier posts.

Epoxy is different. It is a chemical cure. It doesn't need air to cure. The chemical reaction generates heat and heat makes the epoxy cure even faster. The thicker the coat the more heat is generated and the faster the whole coat cures. So putting new epoxy over partially cured epoxy actually makes the entire coating cure faster. Once the epoxy cures for roughly 48 hours the next coat doesn't form a chemical bond. So it really is better to recoat as soon as you can....without undo sacks and such of course.

If you are the type to enjoy experiments......mix up a batch and pour some on aluminum foil so you have a thin coat. Take the other half and pour it into a tall thin container like a test tube. Put the test tube somewhere safe because in a very short time it might get so hot it shatters. The stuff in the test tube will harden MUCH faster.
