QUESTION

What is the best product to use to install resin-backed stone?

ANSWER

Epoxy is the safest choice. You could do a bond test with thinset to see how well it will adhere. Simply install a piece over concrete or concrete board, allow it to dry, and then see how well it is stuck. Some mortar manufacturers are making mortars they claim will adhere to resin-backed stone. If you have a relationship with a representative or a mortar manufacturer, they may have something they will warranty with it. Contacting the stone provider is always your first course of action. If you don’t get answers or test it, use epoxy.
