Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly.

Does humidity affect epoxy?

Epoxies will cure in the presence of moisture brought on by humidity, but in the instance of using table top or the casting epoxy, moisture from humidity will make epoxy cure cloudy and lose clarity (blushing).

What happens if you pour epoxy too thick?
