What are the best adhesives for attaching resin components to stone bases?

Attaching resin components to a stone base requires a strong, durable adhesive that can bond these two different materials effectively. The best adhesives for this task are typically two-part epoxies, high-strength cyanoacrylate (super glue), and certain polyurethane adhesives.

Two-part epoxy is often the top recommendation. It creates an incredibly strong, gap-filling bond that is resistant to moisture and temperature changes, making it ideal for both indoor and outdoor displays. Its longer curing time allows for precise positioning of the resin piece.

For a faster bond, a high-strength cyanoacrylate glue, especially a gel formula, can be very effective. It bonds quickly and firmly, but works best on smooth, flush surfaces where there are no gaps.

For a versatile option, polyurethane adhesive expands slightly as it cures, filling any tiny voids between the resin and the porous stone. It provides a very resilient, waterproof bond.

For any adhesive, ensure both surfaces are clean, dry, and free of dust or oil for the strongest possible hold. Clamping the pieces together during the initial cure period is also highly recommended.
