INSTRUCTIONS FOR SYRINGE:
MIXING STICK AND TRAY INCLUDED.
1. Prepare Surfaces: Protect your work area from spills. Clean and dry surfaces, removing dirt, grease, oil, and rust with sandpaper or a degreaser for the best bond. Do not use alcohol or any other cleaners that may leave a petroleum residue.
2. Dispense & Mix: Remove the "Snap and Save" cap from the syringe and save for later. Depress the plunger to dispense equal amounts of resin onto the included plastic tray or a clean, disposable surface. Mix until the color is uniform (approx. 1 minute).
3. Apply & Join: Apply the mixed epoxy to one surface, press parts firmly together, and clamp if necessary for heavy objects. Open work time is 25–45 minutes.
4. Cure: Sets in 3–6 hours at room temperature. Fully cures in 15–24 hours.
5. After Use: Pull the plunger back slightly, wipe the nozzle clean and replace the “Snap & Save” cap securely to prevent drying. Remove excess epoxy with a clean, dry cloth.
