Custom-made designs are unique to the creator and are impossible to find on the market. That is why knowing how to make silicone molds can set you apart from other crafters.

The best part is that a DIY kit will get you a quick start to making your custom silicone molds.

Check out the section below to discover the exciting methods of how to make your own silicone molds.

How to Make Silicone Molds

Silicone And Liquid Soap Method

What you’ll need:

To make the silicone molds, you can use the silicone and liquid soap method.

To begin, you need to fill a bowl with room temperature water and add a 1:10 ratio of liquid soap with water. Make sure that you mix them well.

After you are done with mixing, now you can add construction silicone to the water.

Now you need to wear a pair of gloves and knead the silicone while keeping it under the water for around 5 minutes. Do it until the silicone becomes loose.

Next, get the silicone out and knead for a bit longer with your palm.

Rest the silicone on a board and place your desired structure into the silicone. You may push the silicone into a cookie cutter to create a defined shape for the outline of your mold.

Let it dry for several hours.

When the silicone hardens up, take out the structure, and your silicone mold is ready for your use.

Silicone And Cornstarch Method

What you’ll need:

Silicone and cornstarch can also help you make silicone molds for yourself.

For this method to work, you need to get construction silicone in a bowl and add twice the amount of cornstarch to the silicone.

Knead them together until they combine properly. Add more cornstarch if the silicone is still sticky.

Then roll the silicone and cornstarch mix to a board and place your desired shape in the silicone. You may push the silicone into a cookie cutter to create a defined shape for the outline of your mold.

Wait for around 20 to 30 minutes for the silicone to dry properly and then take out the item.

Now your silicone mold is ready for the use. This is a quick method to make silicone molds.

Silicone Rubber Method

What you’ll need:

The third method to create silicone molds is to use silicone rubber products created specifically for silicone mold crafting. This will lead to much better looking and higher quality custom molds.

Choose a cookie cutter that your object(s) will fit in – this will be the outline of your mold.

Tape over the opening on one side of the cookie cutter, leaving the sticky side of the tape facing inwards towards the cookie cutter.

Place the cookie cutter with the taped side down, then press the object(s) you are molding onto the sticky side of the tape within the cookie cutter. Ensure they are firmly placed and flat.

For the next step, do this over paper or something you are okay with getting glue on. Hold the cookie cutter down and cover the outside edges of it with glue using a hot glue gun. This ensures a proper seal.

Mix the silicone rubber according to the directions on the package, and then pour it into the cookie cutter until it is filled. Carefully place it in the fridge for a couple of hours.

After you’re done cooling the mold, you may remove the mold and tape from the cookie cutter, and remove the object from the mold. You now hold your own custom silicone mold.

Now that you know the three methods of making silicone molds, you can choose one that works well for you. You can make as many custom designs as you want.

  1. I know commercial silicon mold compounds can be used in a toaster oven for use with polymer clay. Can your first two homemade mold compounds be used in a toaster oven? Or do you recommend strictly for use with resin? Thanks.
