deep pour epoxy

Deep pour epoxy is a specialized casting resin formulated for thick, single- layer pours, making it ideal for projects like river tables, large molds, and deep encapsulations where you want a clear, bubble-free, glass-like finish.

Key Features

  • Deep pour epoxy allows you to pour at depths ranging from 2 inches up to 4, or even 12 centimeters (about 4.7 inches) in a single pour, depending on the product and environmental conditions.
  • It has lower viscosity than tabletop epoxies, resulting in better self-leveling and easier degassing, which minimizes microbubbles and produces a clearer finish.
  • Extended working times and slow cure rates prevent excessive heat buildup—reducing risk of cracking or yellowing during thick pours.

Deep Pour Epoxy vs. Tabletop Epoxy

Property| Deep Pour Epoxy (Casting)| Tabletop Epoxy
---|---|---
Recommended Layer| 2–5 inches, some up to 12 cm (4.7 in) 234| Up to 1/8 inch (0.3 cm) 15
Viscosity| Lower, flows easily and self-levels| Higher, more like thick syrup
Cure Time| 18–72 hours, full cure up to 2 weeks 25| Hours to overnight
Ideal Use| River tables, large castings, embedding| Countertops, bar tops, thin coats
Bubble Resistance| Very high (self-degassing)| Moderate, best in thin layers

Application Tips

  • Pour within recommended thickness for your resin—exceeding can cause excessive heat and defects. For very thick pours, some resins recommend layered pouring.
  • Work in a cool environment to further reduce the risk of overheating. Carefully monitor the temperature, especially for pours thicker than 2 inches.
  • Always mix thoroughly and use the manufacturer’s mixing ratios for optimal results. De-gas with a flame torch or heat gun for a flawless finish.
  • Allow at least 18–24 hours for initial cure and up to 3 days for a solid, usable surface. Full chemical hardening can take 2+ weeks.

Typical Uses

  • River tables and thick tabletops
  • Encapsulating natural objects (flowers, wood, stones)
  • Large jewelry pieces, resin art, and sculptures
  • Scientific or technical applications requiring thick, transparent castings

Deep pour epoxies are essential for thick, crystal-clear castings. Always follow specific product instructions for safe and successful results.
