🪣 Total Epoxy Volume Needed

0 fl oz

🪣 Epoxy volume formula: Length × Width × Thickness = Cubic inches ÷ 1.805 = Fluid ounces. Add 10% waste for mixing cups, spills, and coverage variations.

💡 Pro tip: Tabletop/coating epoxy (1/8″ pour) uses ~1 oz per sq ft. Deep pour epoxy requires multiple thin layers to prevent overheating. Always follow manufacturer’s recommended pour depth.
