Can I pour epoxy over epoxy?

Can I put another coat of epoxy over cured epoxy? Yes. Since the epoxy has cured a chemical bond is not possible so what is called a mechanical bond is needed. This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.

All the layers of epoxy cure together in a single fused layer. Epoxy applied over partially cured epoxy will chemically link with it and is a primary bond. The ability to chemically link diminishes as the epoxy cures and it becomes a secondary bond.

Why is my resin bendy after 48 hours?

In most cases, the reason you have resin that bends is due to the fact that the resin needs more time to cure. After 24 hours, ArtResin will be at a 95% solidity rate. If you attempt to curve or move the resin before that 24 hour mark, the resin will likely bend.

Can you spot fix epoxy?

An uneven hardening of your epoxy resin can lead to dull, or even tacky spots.
