Our Extreme Liquid and Ultimate Putty are two-part epoxies that deliver extraordinary strength and unmatched versatility with their multi-purpose formulas.

Both form an incredibly strong bond on virtually any material. From heavy-duty repairs to precision fixes, Flex Seal Epoxies create a durable, permanent bond you can rely on for your toughest jobs.

*Lift and strength tests were conducted in controlled environments for demonstration purposes only. Attempting to replicate these tests is extremely dangerous and strongly discouraged. Do not attempt.
INSTRUCTIONS FOR SYRINGE:
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 colour 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.
