How to use this product data

EpoxyCalc currently catalogs this system for river table, deep pour, mold casting. The stored general maximum layer is 50.8 mm (2.0 in). The listed mix ratio is 2:1 by volume. Always measure using the method stated by the manufacturer because weight and volume ratios are not automatically interchangeable.

This page is a planning reference, not a substitute for the current technical data sheet. Re-check the manufacturer guidance before a large pour, especially when temperature, total mass or project geometry is near a published limit. Product availability and prices can also change after the verification date shown above.

Need the exact resin and hardener amounts for this product's published ratio? Use the resin and hardener ratio calculator and keep the manufacturer's weight / volume basis unchanged.

Verified notes

  • The product page advertises 2 in pours.
  • Upstart's FAQ recommends limiting larger projects to 1.5 in per layer, so EpoxyCalc uses 1.5 in for river-table and general large deep-pour planning.
  • Additional layers can be poured after the prior layer reaches a tacky cure, approximately 24 hours according to the manufacturer.
