If you’ve opened a can of Eterna-Kote Silicone Roof Coating and didn’t use it all, you don’t need to worry—this high-performance coating is designed to be stored and reused when handled correctly.
With the right approach, you can keep your coating in excellent condition for future touch-ups or projects.
Why Eterna-Kote Silicone Roof Coating Stores So Well
Eterna-Kote Silicone Roof Coating is a 100% silicone, moisture-cure coating, which means it only begins to cure when exposed to air and humidity.
That gives you a major advantage:
- Inside a properly sealed can, the product remains stable
- It retains its thick, high-build consistency
- It stays ready for reuse without performance loss
This makes it a cost-effective and low-waste roofing solution.
Best Way to Store an Open Can
Follow these simple steps to keep your coating in top condition:
Open the can, take out what you need and put the lid straight back on
Seal It Airtight
Press the lid down firmly to prevent air and moisture from entering. A tight seal is the most important factor in preserving the product.
Reduce Air Inside the Can
If the can is partially used, place plastic wrap over the opening before sealing. This helps minimise trapped air.
Store in a Cool, Dry Place
Keep your coating out of direct sunlight and away from extreme heat or cold. Stable temperatures help maintain quality.
Keep the Rim Clean
Wipe excess coating from the rim before sealing to ensure a proper closure and easy reopening later.
How Long Does It Last After Opening?
When stored correctly, Eterna-Kote Silicone Roof Coating can remain usable for a long period after opening.
Before reuse, check:
- Smooth, thick texture
- No full curing throughout the can
- Minimal surface skin (which can be removed if present)
If it passes these checks, it’s ready to apply again.
Built for Performance—and Practical Use
One of the key benefits of Eterna-Kote Silicone Roof Coating is that it’s not just durable on the roof—it’s also practical off the roof.
- Perfect for future maintenance or touch-ups
- Helps reduce product waste
- Maximises value from every can
