When starting a resin project, knowing how thick you can pour each layer is essential for achieving clear results and preventing problems like overheating or cloudy finishes. The permissible thickness depends strongly on the type of resin selected.
Understanding Resin Pour Thickness
Not all resins are suitable for deep pours. Standard epoxy resins are typically used for layers up to 2cm. For thicker applications, such as tabletops or art pieces, deep pour resins are specially formulated to allow increases in casting depth—sometimes up to 10cm per layer for certain products.
Always check the manufacturer’s guidance on maximum thickness per pour. Exceeding these limits can lead to overheating, bubbling, or incomplete curing, which can compromise the strength and clarity of your project.
Choosing the Right Resin for Your Project
If your project involves casting heights greater than 5cm, look for a specifically designed deep-casting resin. For example, Epoxytable 10-Ten is suitable for up to 10cm in one pour, making it ideal for large river tables and thick decorative castings. Complete kits such as the River-Table Kit typically support up to 2–5cm per application, making them appropriate for most beginner and intermediate projects.
- For layers under 2cm: Standard resin kits are typically sufficient.
- For 2–5cm: Deep pour kits are recommended.
- Up to 10cm: Select specialised deep-casting resin only.
When Thickness Matters
Large furniture pieces, artistic sculptures, or casting in thick moulds demand a resin that can handle substantial volumes. Using the wrong type could lead to trapped air or excessive heat, ruining the finish. For jewellery or smaller pieces, a thinner pour is both safer and easier to manage, like with the Evershine Collection jewellery kit.
