Why does resin cracking happen? Cracking happens when resin gets too hot and cools off quickly.
Why does my resin keep cracking?
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)
Does epoxy crack easily?
Do Epoxy Floors Crack? Epoxy floors are very rigid. As a material, epoxy has very little flexibility, so slight shifts in the foundation can lead to cracks forming in an epoxy coating, leaving you with cracked floors that are difficult to repair without recoating with a new layer of epoxy–an expensive proposition.
Why did my deep pour epoxy crack?
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.

How cold is too cold for epoxy?
Because the epoxy will probably go dormant below 35-40°F, but will begin to cure again once the temperature rises.

Take care to avoid heating the surface or any standard epoxy to over 200°F.
Does epoxy dry better in heat or cold?
Warmer temperatures accelerate the reaction, while cooler temperatures retard the reaction and reduce the cross-linking activity of the epoxy molecules. All epoxy resin/hardener combinations go through the same phases of cure. All combinations cure faster at warmer temperatures and cure slower at cooler temperatures.
