In this blog post, you’ll learn the basics of making moulds for your epoxy resin crafts, as well as techniques and tips for creating custom pieces. Get ready to explore the world of epoxy resin arts and crafts.

The Key Role of Moulds in Resin Artwork

Moulds play a crucial role in resin art, allowing artists to create intricate shapes and designs that would be difficult to achieve by pouring resin directly onto a surface. Here's why moulds are essential in resin artwork:

Achieving Desired Shapes and Textures

Moulds enable artists to create specific shapes and textures in their resin artwork. Whether it's a smooth and glossy finish or a textured surface with intricate details, moulds help artists bring their creative visions to life.

Consistency and Replication

It ensures consistency in resin art projects, allowing artists to replicate their designs multiple times. This is particularly useful when creating a series of artworks or when selling resin art pieces.

Flexibility of Silicone Moulds

Silicone moulds are widely used in resin art due to their flexibility and ease of demolding. The soft and pliable nature of silicone allows for the effortless removal of cured resin without damaging the mould or the artwork.

Complex Designs

Silicone moulds come in a variety of shapes and sizes, making it possible to create complex designs with fine details. From geometric patterns to delicate flowers, silicone moulds offer endless possibilities for resin artists.


Moulds are not limited to specific shapes or sizes. Artists can make custom moulds for their unique designs or use ready-made objects like containers, kitchen utensils, or even natural objects as unconventional moulds. This versatility opens up a world of creative possibilities.

Creating Custom Silicone Moulds for Resin Art

Making your own silicone mould for resin art is a great way to customise your creations according to your artistic vision. By following these step-by-step instructions, you can create unique moulds that will allow you to explore new possibilities in your resin art projects.

Prepare the Original Object or Sculpture to Be Moulded

Before you begin creating the silicone mould, you need to ensure that your original object or sculpture is clean and free from any dust or debris. You can use soap and water or a mild cleaner to gently clean the surface of the object. Once it is clean, let it dry completely before proceeding.

Construct a Mould Box to Contain the Silicone

To contain the silicone while it cures, you will need to create a mould box using materials such as foam board, plastic containers, or cardboard. The mould box should be slightly larger than your original object and should have enough height to accommodate the desired thickness of the silicone mould.

Mix and Pour the Silicone Rubber

Next, you will need to mix the silicone rubber according to the manufacturer's instructions. This typically involves combining two parts of silicone rubber (a base and a catalyst) in a specific ratio and stirring them together thoroughly. Once the silicone is mixed, pour it slowly into the mould box, making sure to cover the entire original object or sculpture.

Demould and Remove Any Imperfections from the Silicone Mould

After allowing sufficient time for the silicone to cure (usually 24-48 hours), carefully remove the mould from the mould box. Gently peel away any excess silicone and trim off any rough edges or imperfections using a sharp knife or scissors. You now have a custom-made silicone mould ready for your resin art projects!

Other Techniques for Resin Art Mould Making

Making moulds for resin art doesn't always have to involve creating custom silicone moulds from scratch. There are alternative techniques that allow you to create unique mould designs. Let's dive into some of these creative options:

  • 3D-Printed Moulds: With advancements in technology, 3D printing has become more accessible and affordable. You can design and print your own custom moulds using a 3D printer, allowing you to create intricate and precise shapes that may be difficult to achieve with traditional mould-making techniques.
  • Fabric-Based Moulds: Fabric can also be used as a mould material for resin art. By soaking the fabric in resin and draping it over a support structure, you can create unique textures and patterns. Experiment with different types of fabric, such as lace or mesh, to achieve different effects in your resin art.

Tips for Successful Resin Art Mould Making

When it comes to resin art mould making, several tips and techniques can help ensure successful results. From proper measuring and mixing of materials to preventing air bubbles and releasing the resin from the mould without damage, here are some valuable tips to keep in mind:

Measure and Mix Properly

Accurate measurements of resin and hardener are crucial for achieving the desired consistency and curing of the mould. Use graduated cups or digital scales to measure the components precisely. Follow the manufacturer's instructions regarding the resin-to-hardener ratio for optimal results.

Use Mould Release Agent

Applying it before pouring resin into the mould can make demoulding easier and prevent damage to both the mould and artwork. Silicone-based release agents are commonly used for silicone moulds. Petroleum jelly or cooking spray can be effective for other types of moulds.

Create Vent Holes

For complex or deep moulds, consider adding vent holes to allow air to escape during the pouring process. This helps prevent air pockets from forming. Ensures even distribution of resin throughout the mould.

Demould Carefully

When it's time to remove your resin art from the mould, take your time and be gentle to avoid any damage. Flexing or twisting the mould slightly can help release stubborn pieces without causing breakage.


In conclusion, mould-making is an essential skill for anyone interested in epoxy resin crafts. By learning how to create moulds, you can unlock a world of creative possibilities and push the boundaries of your resin creations. Moulds not only enable you to replicate intricate details and designs with ease but also give you the freedom to experiment with different colours, textures, and shapes. With the right mould-making techniques and materials, you can create stunning resin crafts.
