Max Depth Per Pour: This deep cast resin is a slow speed casting system specifically designed for a low exotherm for deep pours (50-100mm thick in a single pour) however pours from 10-100mm are possible conditions dependant , curing times based on overall volumes and conditions will fluctuate 

Usage Advice: For best results, pour at temperatures between 15-20 Degrees C (volume and depth dependent) and below 70% humidity. Like most deep cast resins air bubbles may form on the surface. Air bubble release is greatly enhanced by use of a heat gun or gas torch.

Care should be taken to avoid over heating in one spot – sweep the heat gun continuously across the surface for a few seconds.


Mixing Volume: The cure speed of this product depends greatly upon the volume of product mixed. This product is specifically designed for large volume mixes. Thin casts or applications as a coating will exhibit a longer cure time.
