If you want more consistent results from your molding process, you want to use a mold release spray to ensure you experience as little damage and struggle as possible during the release process. While these products are designed around convenience and simplicity, don’t mistake that for a no-thought spray-and-go application.

If you want to get the most out of a product, take the time to learn how to use a mold release spray properly so that you ensure the successful and consistent release of your industrial molded goods time and time again.

The use of mold release sprays is not complicated, but multiple-minute steps can impact the success of this product's protective layer. Following these steps isn’t difficult but can have an outsized impact on the results of your molding process:

Prepare the surface

Thoroughly clean your mold’s surface with an industrial mold cleaning product – or a mild detergent in a pinch. A mold release spray forms an air-tight layer of protection, but any dirt and debris on the mold surface at application can cause poor adhesion or unintended damage during molding. This grime may even accelerate long-term damage like rust and hairline cracks.

Shake the Mold Release Spray Can

Shaking the can of mold release spray will agitate the product inside, ensuring that the pressure of the aerosol is even and high for consistent application across your mold’s surface. This also ensures the product inside is well mixed, reversing any settling since manufacturing.

Apply the Mold Release Spray Evenly

Hold the can of aerosol mold release spray about a foot away from the surface and apply a thin and even layer of the product across the mold surface. Apply this to the entirety of the working surface, but avoid over-spraying that might lead to pooling of liquid or uneven application.

Allow the Spray to Dry

Suppose you were to immediately begin molding after applying your water-based mold release. In that case, it may still be liquified, resulting in an unsightly surface or damage to the resulting molded goods. This time may vary depending on the humidity levels and spray type, so consult your product instructions for a better idea of how long to wait.

Reapply Between Uses

Not all mold release sprays are designed for use between multiple molding cycles, so it is advisable to re-apply after each release. Some of the products might stick to the molded good’s surface upon release or otherwise degrade during the molding process. Simply follow the application process again after each cycle.

Clean When You Are Finished Using Your Mold

Once you have finished your day’s work or are ready to swap molds, clean any leftover mold release spray residue from your mold’s surface using a mold cleaner. If you plan to store this mold for a time, use a rust preventative agent to protect your equipment from oxidation and long-term damage.

Mold Release Spray Tips

While the use and application of mold release can be simple, you can take some small steps to ensure that your application is safe, effective, and successful:

• Choose the Right Spray For Your Needs: Consult our experts to ensure that you use the appropriate mold release product for the materials you use, the process you employ, and the applications your goods are designed for. Water-based and oil-based sprays have very different usage, for instance.
• Use in Ventilated Areas: never use an aerosol in an enclosed area, especially a chemical product such as a release spray.
• Avoid Overspraying: Over-application of a spray can result in pooling, uneven application, or other issues that can result in your process's damaged or poorly molded results.
• Read Instructions: We understand that you might skip directly to applying your mold release spray, but reading the instructions and advice specific to the spray you chose can help avoid costly errors.
• Use Appropriate Protective Gear: During your process, you should use protective gear such as gloves, goggles, and masks to protect yourself from the product. Your eyes, skin, and respiratory system are particularly important and sensitive to chemicals of this nature.
• Store Mold Release Spray Appropriately: When not in use, tightly close the canister of mold release spray and store it in a cool, dry place that is out of direct sunlight and away from heat/flames. Consult your product manual for more specific information.
