With proper care and maintenance, silicone moulds can last for years and produce consistent, high-quality results.

How to Keep Silicone from Sticking to Silicone Moulds?

One of the biggest challenges when using silicone moulds is preventing the silicone from sticking to the mould. Here are some of the most common causes of silicone sticking to moulds:

1. Improper preparation: If the mould is not properly cleaned and dried before use, or if it is not properly greased, the silicone can stick to the mould and be difficult to remove.
2. Poor quality moulds: Low-quality silicone moulds can be prone to sticking, even if they are properly prepared. Look for high-quality silicone moulds that are designed for the specific purpose you have in mind.
3. Over-filling the mould: Over-filling the mould with silicone can cause it to stick to the sides of the mould. To avoid this, only fill the mould to the recommended level.
4. Incorrect curing time: If the silicone is not given enough time to cure, it may not fully set and can stick to the mould. Be sure to follow the manufacturer’s instructions for curing time.

To prevent silicone from sticking to silicone molds, it’s essential to properly prepare the moulds before use. This includes cleaning and drying the mould thoroughly and using a food-grade grease or oil to prevent sticking. Applying a thin layer of oil or grease to the mould can help create a barrier between the silicone and the mould, making it easier to remove the finished product. It’s also important to avoid over-filling the mould and to follow the manufacturer’s instructions for curing time.

What is the Lifespan of Silicone Moulds?

The lifespan of a silicone mould can vary depending on a variety of factors, such as the quality of the mould, frequency of use, and the type of material being used in the mould.

In general, high-quality silicone moulds that are properly cared for and used can last for several years. With proper cleaning, storage, and usage, silicone moulds can maintain their shape and durability, producing consistent and high-quality results over time.

However, it’s important to note that silicone moulds are not indestructible and will eventually wear out with regular use.
