Can I Craft Resin Magnets Without Using a Mould?

How to Make Freeform Resin Magnets

If you don’t have a dedicated mould, opt for dome-style resins that self-level and hold their shape on non-stick surfaces. To begin, lay out a silicone mat or non-stick baking sheet. Carefully pour your doming resin into your desired shape — think circles, blobs, or abstract designs. Many resins allow you to add inclusions like glitter or small decals for a personalised touch.

Allow the resin to settle and cure as per instructions, then affix a magnet to the back with a strong adhesive. For optimal results, look for doming products such as the “Be Flex” – Transparent Polyurethane Doming Resin, which gives a flexible, bubble-free finish suitable for freeform applications.

Choosing the Right Resin and Surface

Doming and jewellery-grade resins are generally best for mould-free magnet making, as they will spread smoothly while retaining a glossy finish. Ensure your working surface is non-stick to allow easy removal of the cured piece.

• Avoid pouring thick layers; thin pours help maintain shape and clarity.
• Use toothpicks or stirrers to nudge resin into precise forms, or add pigment for a more decorative effect.
• Allow ample time for curing before handling or attaching magnets.

When to Choose Mould-Free Resin Magnet Crafting

Mould-free techniques are perfect for crafters who want to experiment or work with limited supplies. It’s ideal for making small batches, testing resin finishes, or creating organic-style magnets that stand out from the crowd.
