How to Store It Right and Avoid Application Issues
Silicone roof coatings are known for their strength, flexibility, and long-term protection. But even the best coating won’t perform if it’s expired or stored improperly. Whether you’re a contractor or facilities manager, understanding silicone coating shelf life and proper storage is key to avoiding headaches on the job.
In this blog, we’ll cover best practices to help you protect your investment and ensure your coating performs exactly as it should.
What Is Shelf Life?
Shelf life refers to how long a product remains usable after its date of manufacture. For silicone roof coatings, this timeframe can vary based on the brand and formulation.
At Progressive Materials, our most popular products — including the 3200 Series Silicone Roof Coating and FG 400 Series Pro Patch Sealant — have a 24-month shelf life when stored correctly. For all of the technical data on each of our products, click here to find our tech data sheets.
Best Practices for Silicone Coating Storage
Proper storage not only extends shelf life — it also protects product integrity and ensures consistent application. Here are the key guidelines to follow:
- Store Between 40°F and 80°F
Temperature matters. Keep coatings in a controlled environment between 40°F and 80°F to maintain quality.
- Avoid Direct Sunlight
Even though the silicone itself is resilient, UV exposure can weaken the storage bucket, which may affect the coating inside over time.
- Keep It Dry
Silicone is moisture-resistant once applied, but humidity during storage can cause problems. Wet conditions may compromise the bucket seal and introduce water into the product. Always store coatings in a dry, covered location to avoid chemical changes or curing issues.
Use FIFO: First In, First Out
Following the FIFO (First In, First Out) method helps ensure you’re using your oldest inventory first, reducing waste and improving consistency across jobs. It’s a simple inventory management step that pays off — especially with time-sensitive coatings.
Signs Your Silicone May Be Expired
Using coatings past their shelf life can lead to application failure and costly callbacks. If you notice any of the following, talk to your PM Regional Manager before using the product:
- Silicone has cured inside the bucket
- There’s significant skinning on the surface
- The product gives off a strong, unpleasant odor

Conclusion
Silicone roof coatings are a smart, long-lasting investment — but only when the coating is in good shape. Proper storage will help ensure you are getting the most of your PM Silicone. Follow these best practices to make the most of your materials:
- Maintain a temperature range of 40°F–80°F
- Avoid sunlight and keep coatings dry
- Use a FIFO system to rotate inventory
- Check expiration dates and inspect for signs of spoilage
