Keeping your leftover silicone glue and casting components in good condition is essential if you want to achieve consistent moulding results and avoid waste. Correct storage extends shelf life and preserves quality for future projects.
Where and How to Store Silicone Glue
Unused silicone glue, as well as the bi-component bases or putties for mould making, should always be stored in airtight containers. Exposure to air, even in small amounts, may begin the curing process or introduce unwanted moisture.
- Keep sealed tightly between uses
- Store at standard room temperature to avoid hardening or separation
- Avoid keeping containers near direct sunlight or sources of heat
Protecting Your Components from Moisture and Sunlight
Dampness can compromise both silicone glues and their catalysts or activators. Always ensure lids are secure and containers are stored in a dry place. Direct sunlight can degrade the quality and consistency, so choose a shaded cupboard or shelf away from windows. For extra peace of mind, you can use silica gel packets to reduce residual humidity inside your storage container.
When Careful Storage Matters Most
Careful storage is particularly important if you purchase silicone in larger quantities, such as with the “Liquid Mould” Casting Liquid Silicone Rubber, or if your workshop is subject to temperature or humidity changes. Consistent storage practice helps prevent premature curing and ensures your materials remain easy to mix and pour when needed.
