If you invest in a good silicone mould for resin casting, you’ll want to make it last as long as possible. Well-cared-for moulds help you achieve better results and save money over time.
Proper Cleaning After Each Use
Once you’ve removed your resin casting, wash the silicone mould gently using mild soap and water. Avoid abrasive cleaners or scrubbing tools that could damage the surface. Make sure the mould is completely dry before storing it; this helps prevent any unwanted mould growth or residue.
Some specialised silicone moulds, such as the “Pure Mould” – Translucent Liquid Silicone Rubber for Mould Making, are easy to clean thanks to their non-stick properties, making upkeep less of a chore.
Safe Storage Techniques
Always store your moulds flat, away from direct heat, excessive humidity, or sunlight. Heat and UV exposure can cause the silicone to warp or lose elasticity over time. Keeping them in a cool, shaded place maintains their original shape and flexibility.
- Lay moulds flat or nest them carefully if stacking.
- Cover with a lint-free cloth or keep inside a drawer to prevent dust buildup.
Gentle Handling for Longevity
Take care when removing your cured resin. Overstretching or yanking can cause tears, especially in detailed or thin-walled moulds. Flex the sides evenly and ease your creation out, being patient rather than forceful. Minor residue can be loosened by letting the mould soak before removal rather than pulling harshly.
When This Matters Most
If you regularly use your silicone mould for detailed resin art, large castings, or items with embedded objects, longevity is especially important to ensure consistency and avoid deformation over multiple uses. High-quality products designed for repeated professional or hobby use, like the “Pure Mould”, offer extra resilience when cared for diligently.
