After opening a two-part epoxy putty, ensuring its longevity relies on storing the unused components correctly. Here’s how to keep your epoxy putty ready for future repairs and projects.
The Ideal Storage Environment
Both parts of epoxy putty should always be kept in their original, tightly closed containers. Exposure to moisture, air, or high temperatures can cause the putty to harden prematurely, making it unusable. For optimal results, store the containers in a cool, dry place, away from direct sunlight and sources of heat. Garages, utility cupboards, or indoor shelves often work well, provided the area is not humid.
Practical Tips for Resealing and Preservation
After dispensing the required amount for your job, make sure to wipe away any putty residue from the container rims and threads. Replace the lids immediately and ensure they are tightly closed, minimising contact with air. If your product arrived with a seal or foil barrier, reapply it after each use. Avoid swapping utensils between the two components, as cross-contamination can start the curing process inside the tub.
- Keep components separate at all times
- Check for moisture in your storage area periodically
- Label your containers with date opened for easy reference
When This Matters: Protecting Product Performance
Correct storage is crucial if you use your epoxy putty or mastic across multiple projects, such as ongoing repair or restoration work. Since products like the “Magelstick” – Epoxy Mastic are formulated for strong, reliable bonding, improper storage can lead to wasted material and compromised results when you return for your next usage.
