Facebook← Back to Epoxy resin: tips for thick pours of two inches and beyond?
If you’re planning a large or artistic casting that requires a super-deep epoxy pour—anything up to 10cm thick—choosing the right resin is crucial for clarity, safety, and reliable results. Here’s what you should know before you start your project.
Recommended Epoxy Resin for Deep Pours
When pouring epoxy at thicknesses of up to 10cm, it’s essential to select a resin formulated specifically for deep castings. “Epoxytable 10-Ten” is purpose-built for these projects, offering a low exothermic reaction to prevent overheating and maintain clarity throughout thick layers. Its strong UV filters also help keep your work clear and non-yellowing for years to come.
Layering Technique for Large Surfaces
For exceptionally large projects—such as tabletops where one side exceeds 100cm or heavy resin volumes—it’s wise to pour in stages. Instead of a single 10cm pour, apply your resin in two layers, allowing 6–8 hours between each. This controlled approach helps manage heat buildup and ensures a more uniform cure.
Practical Tips for Deep Casting Success
- Always use moulds capable of withstanding both the volume and the temperature of the curing resin.
- Work in a controlled environment, ideally between 18–25°C to minimise unexpected reactions.
- Allow extended curing time—deep pours will set far more slowly than shallow ones.
- The super low viscosity of the recommended resin makes it easier to avoid bubbles, giving your finished piece a professional, glassy appearance.
When This Matters Most
Choosing a resin like “Epoxytable 10-Ten” is particularly important for artistic tables, river tables, and other large, thick clear castings where both structural integrity and optical clarity are priorities.
