Do You Need Mold Release For Silicone Molds.

Silicone is one of the widely used molds for making resin artwork. The ability to be versatile and durable allows the resin to be used repeatedly with losing form.

Resin release allows for ease in removing cured resin art. The resin release prevents resin from sticking, preventing the mold from being damaged. Avoid using silicone-based resin release as this may bond with the silicone mold.

The mold release does prolong the lifespan of your mold. The mold release agent can be purchased and come in different forms. The different release agents are mold-release sprayrelease wax, and PVA Mold Release Lacquer

All the resin varies provided above do the job of releasing silicone from its mold. Still, you must carefully select the correct release agent for the particular task. Applying too much release agent will dull the surface of your mold soft.

Below we will discuss the different types of resin release agents and how to use them in your resin project effectively. We will also discuss alternative release agents if you run out of the store-purchased release agent.

Do You Need Mold Release for Resin In Silicone Molds?

Silicone molds are the easiest way of making resin crafts and allow for proper curing and demolding. Silicone molds are easy to handle and can repeatedly be used to produce the detailed casting. 

It is recommended to use mold release when making your resin craft, as the release agent makes removing the casting from the mold easy.

Using resin release is especially important when taking out a very detailed casting that requires a smooth casting release from the mold. 

The release agent also has the benefit of prolonging the lifespan of your mold. As the silicone mold ages, its surface becomes brittle and hard. Applying for resin release before storing the mold will keep the surface supple and extends its lifespan.

Do You Need Mold Release for Resin In Wood Molds?

Silicone is the most common mold for making resin art. The flexibility and usability allow for ease of use. Wood molds can be used as a substitute for silicone. I won’t recommend using a wood mold for beginners, as the process of making resin art can be unforgiving if not done correctly.

Plywood can be purchased from local stores and improvised to make resin mold. Wood is rigid compared to silicone and requires specialized tools like bandsaws. Plywood is prone to being and skill needed while creating the desired mold.

A release agent is needed before pouring the resin into the mold. Resin is prone to sticking to the wood. The resin release can also be absorbed into the wood if the resin is poured after a period. When purchasing the resin release, read the manufacturer’s instructions to ensure the release agent can be used with wood.

What Can I Use As A Silicone Mold Release?

Mold-Release Spray.

The spray is a combination of wax and aerosols. The spray is suitable for small and detailed molds. The spray can be easily applied and reach the hard-to-reach clavicle and detailed portions of the resin mold.

The aerosol carries the resin release, which, when applied, covers the resin mold. Once the resin release has been applied, the resin solution must be applied immediately. Mold release spray evaporates if left alone for a long time without inserting the resin solution.

Before applying the resin release, the mold surface needs to be prepped. Remove any dirt, debris, or grease that may have adhered to the surface. These foreign objects pose a risk of the release agent not sticking properly to the mold.

Once the resin has cured and is ready to release the final product, the unwanted dirt and foreign objects will meld with the end product. 

One of the most popular resin release sprays is the E206 Silicone Mold Release. The popularity of the spray is based on the versatility and high performance of the lubricant. The spray can be used on mold materials such as rubber, plastic, and wood.

If you are working with silicone, I recommend using other release agents. A better option for silicone is release wax. The release spray does reduce the chance of the resin sticking to the mold causing damage to your resin artwork.

Mold Release Wax.

The release agent comes in a can or container and not in spray form. The release comes in a pastry consistency. The wax can be applied by hand and using a brush or dry cloth.

You can pour the wax on the cloth and apply the wax on the mold. The wax provides greasy coverage on the mold, which can be slippery when removing the resin art once cured.

The mold release agent must be cleaned thoroughly before the next resin art is made. Cleaning the mold prevents the dirt and debris from getting on the mold and results in the transfer of foreign substances to your next project.

Use a clean cloth to remove the excess wax from the mold surface. Have the resin mold dry for at least 24 hours before the resin projects.

PVA Mold Release Lacquer.

 The release agent is best needed whenever the resin is likely to stick to the mold. This release agent is recommended for first-time mold, which has never been used before. 

The release agent can also be used for demolding castings. Most PVA release agents are combined with wax release agents for the best result.

Applying the PVA Release can be applied in different ways. Review the manufacturer’s instructions before applying the release agent. The release agent can be applied using a brush or clean sponge.

What can I use instead of mold release? 

Several alternative release agents can be made from household products. Sometimes you may need more of the suggested release agent provided above. The products used as an alternative to the release agent described above must be used sparingly. The result provided by the alternative resin release produces a different result. 

Vegetable oil: The ingredients in the vegetable oil provide the lubrication needed for ease in removing the cured resin from the mold. The vegetable oil can be applied using a dry paper towel. Be careful to avoid pooling the oil in the lower crevices of the mold. 

Petroleum Jelly: Vaseline can be used as a release agent for molds that don’t have too many details. Vaseline has a wax texture that can be applied using a dry washcloth. Once the resin has cured, ensure the mold is cleaned thoroughly before the next project.
