Getting the thickness right is vital when casting with epoxy resin. Every resin has a recommended safe limit per pour to avoid issues like overheating or cloudiness. Here’s how to select the right resin and technique for your project’s depth.
Typical Pouring Thickness Guidelines
The maximum casting thickness will vary depending on which epoxy resin you use:
- Up to 1.5cm per pour: Best for Icrystal resin, ideal for surface coatings and small crafts.
- Up to 2cm per pour: Suited to Trasparente resin, perfect for jewellery, details, and smaller items.
- Up to 5cm per pour: Use EpoxyTable 5-Five for thick tabletops, river tables, and deep castings.
Exceeding these limits can make the resin overheat, crack, or cure unevenly.
Tips for Deep Casting: Multi-Layer Techniques
If your project needs to be thicker than your resin allows in one go, pour in several thin layers. Let each layer cure before pouring the next. This reduces heat build-up and gives a clear, even result.
Avoid pouring resin in a warm environment and never try to speed up the curing process with a heat source, which can lead to overheating and cloudy casts.
When This Matters Most
Getting thickness right is crucial for projects like river tables, large castings, and deep decorative pieces. For flatter objects or jewellery, thinner layers not only cure more safely but also give a more polished result.
