Slightly offbalanced Epoxy-Resin: can it be saved? (self.woodworking)

Hey, I am asking here because I found no better community.

I am using Epoxy Resin quite a lot simply for glueing stuff together, not the other type for like transparent furniture and all.

I glued something but added too much resin and too little of the "Härter" compound.

So it stays sticky.

I read heat could help but doubt it. Do I need to remove it and apply again?

With polyester resin, the amount of hardener determines how fast it sets. The hardener works kind of like a catalyst bringing about a change in the resin.

With epoxy resin, you have to get the mixture right. It's two substances that react with each other and use each other up to produce a third, solid, substance. If you don't get the mixture right one of the two liquids will not be completely consumed. If it doesn't set within the pot life listed by the product, remove it, thoroughly clean the mating surfaces, and try again with the correct mixture.

Exactly what are you gluing with epoxy? You may be able to clean the joint and re-glue it.
