- Storage: Store in a cool, dry place, away from direct sunlight and out of reach of children and pets.
- Disposal: Dispose of cured material and packaging according to local regulations.
3. Preparation and Application
3.1 Surface Preparation
For optimal adhesion, ensure the repair surface is clean, dry, and free from grease, oil, dirt, or loose debris. Lightly roughen smooth surfaces with sandpaper for better bonding.
3.2 Mixing the Putty
- Cut or break off the desired amount of putty from the stick. It is recommended to work with smaller amounts for larger repairs to ensure workability before hardening.
- Knead the putty thoroughly with your gloved hands until it reaches a uniform color (typically gray). The mixing process activates the epoxy and hardener. Warming the putty slightly can make it easier to knead.
- The putty will become warm during mixing, indicating the chemical reaction is occurring.
3.3 Application
- Immediately apply the mixed putty firmly to the repair area.
- Press the putty into cracks, holes, or gaps, ensuring good contact with the surface. For filling larger voids, you may need to build up the putty in layers or use a backing material like wire mesh.
- Shape and smooth the putty as needed before it begins to harden (within 15-20 minutes).
4. Curing and Finishing
4.1 Curing Time
- The putty will begin to harden within 15 to 20 minutes after mixing.
- Allow 24 hours for the putty to achieve its full cure strength. Avoid stressing the repaired area during this period.
4.2 Finishing
Once fully cured, the Rectorseal EP-400 Epoxy Putty can be:
- Sanded to a smooth finish.
- Painted to match the surrounding surface.
- Drilled for fasteners or other attachments.
- Taped or machined as required for specific applications.

6. Troubleshooting
- Putty not hardening: Ensure the putty was thoroughly kneaded until a uniform color was achieved. Incomplete mixing of the epoxy and hardener will prevent proper curing. Ensure ambient temperature is within recommended range for epoxy products (typically above 50°F/10°C).
- Poor adhesion: Verify that the surface was clean, dry, and free of contaminants (grease, oil, dust). Roughening smooth surfaces can significantly improve adhesion.
- Short working time: The putty has a working time of 15-20 minutes. Work quickly after mixing. For large repairs, mix smaller batches to manage working time effectively.
