← Back to Epoxy resin. Single or multiple pours?

Working with epoxy resin on projects larger than 100cm can be highly rewarding, but it also brings unique technical challenges. Layering your epoxy pours is the key to achieving a clear, strong, and defect-free finish on grand-scale creations.
Why Layering is Essential in Large Epoxy Projects
When epoxy resin is poured in substantial volumes or over very large surfaces, it naturally generates heat as it cures. In projects exceeding 100cm on any side or when working with more than 8kg at a time, this heat (from the exothermic reaction) can build up rapidly and cause uneven hardening, unwanted bubbles, or even cracks and discolouration. By working in thinner layers and allowing each to partially cure before adding the next, you keep temperatures controlled and reduce the risk of costly imperfections.
Practical Layering Techniques
Success with layered pouring depends on choosing a resin formulated for deep or staged casting. Typically, let each layer start to gel (but not fully cure) before the next pour; this could mean waiting 6–8 hours between layers for many deep-cast formulas. Always follow the product instructions for maximum layer thickness per pour.
- For layers up to 10cm: Epoxytable 10-Ten is engineered for super-deep pours with low exothermic reaction.
- For layers up to 5cm: EpoxyTable 5-Five is a popular choice for deep tables and large river projects.
- For thinner layers up to 2cm: Trasparente multipurpose resin works well for more detailed or decorative work.
Always ensure suitable room temperature and avoid heat sources to help control the cure.
When Layering Matters Most
Layering is especially important if your project exceeds 100cm in any dimension, or if you’re using high volumes of resin. Tall table rivers, thick slab coatings, or extensive artistic pours all benefit from careful staged casting to manage heat and safeguard your result.
