How to Choose a Mould Release for Silicone Moulds

← Back to How do you make resin mould release?

If you’re casting resin in silicone moulds, the right mould release agent keeps your moulds flexible and ensures your projects demould cleanly every time. Here’s what works best for silicone moulds and how to use it for excellent results.

Why Silicone Oil Works Best

Silicone oil is widely recommended as a release agent for silicone resin moulds. Unlike some oils or waxes, it creates a truly non-adhesive surface that stops resin from sticking, yet it doesn’t damage the flexible structure of your mould. Regular use of Silicone Oil for Mould Protection and Easy Release – 15ml helps extend the useful life of your mould, making it a cost-effective choice for both beginners and professionals.

How to Apply Silicone Oil

Before casting, apply a light layer of silicone oil evenly across the whole mould surface. You can do this using a soft brush or a lint-free cloth, taking care not to use too much—just enough to create a fine barrier. Allow a minute for the oil to spread and settle before pouring your resin. After your piece sets, you’ll notice an easier, cleaner release with minimal residue left behind, which preserves your mould’s detail and shape.

When This Matters Most

Using a suitable mould release is vital when you want to prolong the flexibility and clarity of expensive or detailed silicone moulds. It’s especially important for repeat use or when working with intricate designs that might otherwise stick or tear.
