About this product

A casting resin with a long pot life of 8 to 12 hours and a 3 day demold. Thinner pours cure more slowly and thicker ones run hot, so the 1.5 inch reference matters.

Using this specific product

EcoPoxy FlowCast is listed here as the Deep-pour casting resin version for river tables, deep pours, and casting. For casting resin, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Deep-pour casting resin; related versions can use different timing.
  • For river tables, deep pours, and casting, pay particular attention to accurate mixing, mold material, mass and room temperature.
  • At 21°C and 50% relative humidity, for a 1.5 inch pour.

How to check readiness

Check the casting itself for flex or tack before demolding. The sheet gives a tacky stage from 20 to 44 hours. The sheet gives set at 44 hours. Flex the mold away at one edge and stop if the casting bends, tears or remains tacky.

Avoid this mistake

Demold time is not necessarily full mechanical cure.
