If you’re planning a resin project that requires a thick, crystal-clear finish, understanding deep pour castings up to 5cm is essential. Choosing the right resin and technique helps achieve strong, visually impressive results for furniture, stairs, or decorative surfaces.
Which Epoxy Resin Is Suitable for Deep Pours?
For castings between 2cm and 5cm thick, it’s vital to select a resin formulated for deep pours. Not all epoxies can handle the heat produced during curing at this thickness—using the wrong product risks overheating, yellowing, or cracking. EpoxyTable 5-Five is designed for just these scenarios, supporting pours up to 5cm and large surface areas over 100cm, while maintaining clarity and good mechanical durability.
Practical Tips for Deep Pour Casting
When working with significant thickness or larger projects, pour in layers if the project exceeds 5cm or goes beyond 8kg of combined resin. Allow 6–8 hours between layers to manage heat build-up, which helps prevent bubbles and ensures an even cure. Always work in a cool, ventilated space, and carefully follow the resin’s instructions to avoid common pitfalls.
- Use moulds that tolerate the working temperature.
- Mix slowly to reduce air bubbles.
- Monitor curing to avoid excessive heat accumulation.
When Deep Pour Matters Most
Deep pour resins are especially useful for creating river tables, slab furniture, or stairs where a substantial, glassy finish is required. Their slow curing, low exothermic reaction, and bubble resistance ensure a high-quality, lasting result for substantial, eye-catching pieces.
