What causes epoxy to crack while curing?
Incorrect mix ratio resulting in higher exotherm, faster gellation, more shrinkage (i.e. too much resin, too much hardener or visa versa) Improper cure resulting in excessive shrinkage (cure temperature too high) Incorrect oven temperature or excessive zoning in the oven (hot spots)

It is water-resistant, not prone to cracking, peeling, or other damage, and it is a highly durable material that will not break easily or shrink once hardened.
Why does my resin keep cracking?
The chemical reaction between resin and hardener as epoxy cures will generate heat. The resulting massive build up of heat can cause the cured epoxy to crack because of the temperature differential between the top and bottom of the container. This uncontrolled heat build-up is called uncontrolled exotherm.
Does epoxy crack easily?
While epoxy coatings themselves do not crack in extreme heat or cold, concrete does. Epoxy coatings cannot withstand the stresses associated with concrete cracks due to settling, dry shrinkage or other factors.
