What Resin Should I Use to Fill and Reinforce Large Voids?

Deep Pour Epoxy for Large Voids

For substantial voids in resin carts, a deep-pour epoxy such as Epoxytable 10-Ten is an optimal choice. It’s specifically designed for thick applications—up to 10cm in a single pour—without excessive heat generation. This prevents cracking or yellowing and makes it ideal for structural reinforcement within large resin features or decorative carts.

Tips for Successful Void Filling

• Preparation: Ensure surfaces are dry, clean, and free from dust or oils. Seal any areas where leakage may occur.
• Layering: For extremely deep or irregular voids, work in staged pours to control curing and reduce the risk of trapped bubbles.
• Curing: Allow sufficient time for each layer to cure fully before adding more resin. Follow the product’s guidelines for best results.

When This Matters

Using an appropriate deep-casting epoxy is crucial when repairs require both strength and clarity—such as in see-through panels or load-bearing parts of a resin cart. Avoid standard resins, as they may overheat or fail to cure properly in thick sections.
