Tips for Mixing and Layering Resin for Lamps

When creating an epoxy resin lamp, knowing how to properly mix and pour your resin is key to achieving a flawless finish. Deep pours require particular care to avoid common pitfalls.

Should You Pour All Resin at Once?

For most lamp projects, especially those involving deep castings, it’s highly recommended to pour your resin in multiple layers. Pouring all your resin at once can lead to excessive heat build-up (exothermic reaction), which may cause cracking, yellowing or surface imperfections. By working in layers, you allow each section to partially cure, reducing the risk of overheating and resulting in clearer, bubble-free outcomes.

How to Approach Layering for Deep Resin Lamps

Start by checking the manufacturer’s guidance on maximum recommended pour depth for your chosen resin. For example, Epoxytable 10-Ten can be poured up to 10cm in a single layer in suitable conditions, while other resins may require 2-5cm per layer. After pouring a layer, allow it to partially cure (until it is firm but slightly tacky) before pouring the next. This ensures good adhesion and reduces visible seams.

Practical Tips for Mixing and Pouring

Use a clean, dry mixing vessel and measure your resin and hardener precisely.
Stir slowly to minimise air bubbles, scraping the sides and bottom thoroughly.
Allow bubbles to rise before pouring—using a heat gun can help release stubborn ones.
Pour each layer gently to avoid disturbing previous layers.

When Layering Matters Most

Layering is especially important for projects over 5cm thick or with large surface areas. It not only guards against overheating, but also gives you better control over effects, inclusions, and decorative elements in your lamp design.
