Installation Notes

Surface preparation is critical for maximum bond strength — clean, dry, and lightly abrade both surfaces before applying. Dispense equal parts of each component and mix thoroughly on a disposable surface before application. Work within the 5-minute open time and allow the full 1-hour cure before loading the joint. Keep away from open flames during application and work in a well-ventilated area.
