About this calculator
Overview
Epoxy resin is a chemical compound consisting of resin and hardener that, when mixed, creates a durable, high-gloss finish. Because epoxy can be expensive, accurate volume calculation is critical to ensure you have enough to finish your project without significant overages. This calculator accounts for project volume and a waste factor for cup loss and surface absorption.

Pro Tips
Pour in a temperature-controlled environment between 70-80°F (21-27°C) for the best results.
Seal porous surfaces like wood with a thin 'seal coat' before the main pour to prevent air bubbles from escaping.
Always mix for at least 3 minutes, scraping the sides and bottom of the container thoroughly.

Fun Facts
"Most table-top epoxies are mixed at a 1:1 ratio, while casting resins are often 2:1 or 3:1."
"Curing epoxy generates heat (exothermic). Pours deeper than the manufacturer's spec can 'flash cure' and crack."
"The specific gravity of most cured epoxy is approximately 1.1 to 1.15, meaning 1 liter weighs about 1.1kg."
Formula: Volume (fl oz) = (L × W × T) × 0.5541; Total = Volume × (1 + Waste%)
