Since it has high cohesive strength, it can fill the gap between adjacent rocks.  As epoxy putties are hard and durable adhesive, you can use them in an extreme environment, but the cons of epoxies are, they will look like clay after getting dry.

On the other hand, epoxy resin is an evident and hard adhesive for gluing rocks. The epoxy resin is used in different shapes of rocks that are not adjusted snugly together. The finishing look of this resin is much clear around the application area. The appearance is wet if you look from a distance. As the resin is liquid, it runs faster.
