Is a UV Lamp Needed for UV Resin Magnets?

If you’re thinking of making resin magnets with UV resin, you’ll want to know if a UV lamp is truly necessary. Here’s what every crafter should know before getting started.

Why You Need a UV Lamp for UV Resin Magnets

To cure UV resin effectively, a UV lamp is required. UV resin remains in liquid form until it is exposed to ultraviolet light, triggering the curing process that hardens and sets the resin within minutes. This results in a strong, glossy magnet that is ready for finishing almost immediately.

Without a proper UV light source, your resin magnets won’t set correctly and may remain sticky, soft, or prone to damage. Using ambient sunlight is unreliable, especially in the UK, so a dedicated lamp ensures the consistency and quality needed for successful resin magnet projects.

Choosing and Using a UV Lamp

When selecting a UV lamp, look for one designed for crafting or nail art, as these typically emit the required wavelength for resin curing. Lamps with a power rating of at least 36W are popular for small craft items like magnets. To use, simply follow your resin’s instructions, placing your moulded pieces under the lamp for the recommended time—usually 2–3 minutes for products such as UV–Creation Fast Acrylic Resin.

Allow items to cool before demoulding to prevent warping

When This Matters

A UV lamp is particularly crucial if you’re working on fast projects, small decorative magnets, or need rapid, mess-free results, such as during workshops or festive crafting sessions. Skipping the UV lamp can result in poor finishes and project delays.
