If you’re using Gorilla Epoxy Ultimate for the first time, or bonding a new type of material, we always recommend trying a test piece first.
1. Prepare your work area and the Surface: It is recommended to use Gorilla Epoxy Ultimate in a well-ventilated area. Be sure your work area is protected from spills. A mixing tray and stir stick are provided.
2. Mixing Gorilla Epoxy Ultimate: Remove stir stick from middle of plunger. Prior to opening, pull back slightly on plunger to help minimize initial product flow. With tip pointing over a clean, disposable surface, snap closure from syringe. Push the plunger to dispense even amounts of resin and hardener onto a clean, disposable, contained surface. Lightly pull back on plunger after dispensing to stop flow. The package itself can be used as a mixing tray. If you flip the plastic blister shell over, you can use the small well as a starter dish to begin dispensing until both the resin and hardener are flowing equally. Once the flow is even, move to the larger mixing well to dispense your even ratio. Using stir stick, mix the two parts for about 20 seconds, until the color is uniform. As you mix, you will notice that the epoxy warms up. This is a reaction that occurs as the resin and hardener combine.
3. Application: After mixing is complete, apply Gorilla Epoxy Ultimate within 3 minutes. The epoxy mixture will continue to thicken, and the bond strength will decrease the longer you wait to apply.
4. Clamping: Clamp surfaces together and leave undisturbed for 30 minutes. Full cure in 24 hours. Cure time dependent on temperature, humidity and quantity applied.
