Best Silicone Sprays for Molds for Resin

Resin crafting can be both rewarding and challenging, especially when it comes to intricate designs. The last thing you want is to struggle with resin sticking to your molds. Thankfully, silicone sprays are here to help. These sprays create a barrier that allows your resin to release smoothly, protecting both your creations and your molds during the unmolding process. In this post, we’ll look at some of the best silicone sprays available in Toronto for resin molds and share tips on using them effectively.

Understanding Silicone Spray

Silicone spray is primarily used as a mold release agent. It forms a protective layer between the mold and the resin, ensuring a smoother release. A major benefit of using silicone spray is its ability to lubricate surfaces, reducing chances of sticking and extending the lifespan of both your resin pieces and molds.

However, not every silicone spray is suitable for every project. It's crucial to choose a product that is compatible with both your resin and mold materials. For instance, some silicone sprays can react poorly with certain plastics, leading to unintended damage.

The Right Products for Your Needs

1. Jigaloo

Jigaloo is a well-known silicone spray, commonly found at Canadian Tire. This multipurpose lubricant is popular among DIY enthusiasts and professionals. While many users report positive experiences, it's important to note that some have experienced issues with specific plastics. For example, testing Jigaloo on a small section of your mold first can help you determine its compatibility without risking your entire project.

Resin Remover is also known to efficiently unclog mold vents, as well as helping eliminate most color deposits and stains on the mold.

Tips for Effective Use of Silicone Spray

To achieve the best results with silicone spray, follow these simple tips:

1. Clean Your Mold Thoroughly

Before applying silicone spray, ensure that the mold is clean and dry. Any dust or leftover resin can impact how well the spray works.

2. Apply a Light Coat

When using the spray, aim for a light, even coating over the entire mold surface. Avoid oversaturating, as this can affect the texture and finish of your resin pieces.

3. Allow Drying Time

Always let the silicone spray dry completely before pouring in the resin. Follow the manufacturer’s instructions for drying times to avoid complications.

4. Test First

Perform a test on a small or less detailed mold to see how the spray interacts with your materials. This step is vital to avoid issues with your main project.

Common Mistakes to Avoid

When using silicone spray for molds, avoid these common pitfalls:

1. Overusing the Spray

Applying too much can lead to resin that doesn’t cure properly or finishes that appear tacky. A light coat is usually sufficient.

Using the wrong silicone spray may damage your molds or lead to negative reactions. Always verify compatibility with your mold and resin before proceeding.

3. Neglecting Proper Ventilation

Silicone sprays can emit harmful fumes. Ensure you work in a well-ventilated area or outdoors whenever possible.
