Maximum Pour Thickness per Epoxy Resin

Understanding Maximum Pour Thickness

Epoxy resins are designed for different casting depths, depending on their formulation. If you pour too thick a layer, the resin may overheat as it cures, risking cloudiness or cracks. Here are the safe maximum single pour thicknesses for three popular options:

• Icrystal: Up to 1.5cm per layer – best for jewellery, thin coatings, or detailed art.
• Trasparente: Up to 2cm per layer – ideal for small to medium moulds, crafts, and shallow surfaces.
• Epoxytable 10-Ten: Up to 10cm per layer – chosen for large tables and thick castings where greater depth is needed.

Practical Tips for Layered Pouring

For casts requiring greater thickness than a single layer allows, it’s best to work in multiple stages. Allow each layer to partly cure (usually until it is tack-free) before pouring the next. This approach helps maintain clarity and reduces the risk of excessive heat build-up, especially with larger volumes. When working with deep pours, consider using a product tailored for depth such as Epoxytable 10-Ten for the best results.

When Pour Thickness Limits Matter

Maximum pour thickness becomes crucial for river tables, cast sculptures, or projects needing a bubble-free, crystal finish in a single layer. Overpouring with the wrong product can cause curing issues or visual defects—always check the recommended limits before starting your project.
