Proper storage of both uncured silicone rubber and finished silicone moulds is essential for maintaining product quality and ensuring the longevity of your DIY moulding materials.
Storing Unmixed Silicone Rubber
Keep containers of uncured silicone tightly sealed to prevent exposure to air, moisture and dust. Store them in a cool, dry place, away from direct sunlight or sources of heat, as warmth and humidity can reduce shelf life or even cause premature curing. Always ensure the lid is firmly secured after each use. If you’re using a bi-component system, like Liquid Mould Casting Liquid Silicone Rubber, make sure to store components separately and mix only the amount you need for each project to keep the remainder fresh.
Caring for Finished Silicone Moulds
Once your moulds are cured and ready, store them flat in a clean spot, away from sharp objects that could leave marks or cause distortion. Regularly dust off any debris and, if you use them often, lightly brush the surfaces with a small amount of silicone oil to help prevent drying or sticking. Silicone Oil for Mould Protection and Easy Release is ideal for this purpose, as it can extend the flexibility and lifespan of your moulds. Avoid stacking heavy items on top of moulds to preserve their shape.
When This Matters Most
Meticulous storage is crucial if you want your silicone materials to work reliably for multiple projects. Hobbyists and professional crafters alike benefit from reduced waste, easier demoulding, and consistent results by adopting these habits.
