| Project Dimensions | Cubic Inches | Total Fluid Ounces | Total Gallons | Part A : Part B (2:1 Ratio) |
|---|---|---|---|---|

| 36" × 10" × 1.5" (Small) | 540 cu in | 2.45 Gallons | 314 fl oz | 209 oz Resin : 105 oz Hardener |
| 48" × 12" × 1.75" (River) | 1,008 cu in | 4.58 Gallons | 586 fl oz | 391 oz Resin : 195 oz Hardener |
| 72" × 16" × 2.0" (Dining) | 2,304 cu in | 10.47 Gallons | 1,341 fl oz | 894 oz Resin : 447 oz Hardener |
Deep-pour formulations must strictly respect maximum single-pour thickness limits (typically 2 to 3 inches) to avoid runaway thermal exotherm (boiling, yellowing, or cracking). Room temperature must be maintained between 68°F and 75°F.
Multiply the length of the river gap in inches by the average width in inches, and multiply by the depth of the pour in inches to get total cubic inches. Divide cubic inches by 1.805 to convert to fluid ounces, or divide by 231 to convert to gallons. Add 5% for container loss.
1:1 ratio epoxies are typically fast-curing table top flood-coat resins designed for thin protective surface layers (maximum 1/8 to 1/4 inch deep). 2:1 and 3:1 ratio epoxies are slow-curing deep pour casting resins designed for deep pours up to 2 to 3 inches in a single pass without overheating.
Quality commercial deep-pour epoxy resin kits cost $85 to $130 per gallon. A standard 48x12 inch river table pour requiring 4 to 5 gallons costs roughly $380 to $600 for resin alone.
Only if the manufacturer specifies weight ratios. Epoxy resin (Part A) and hardener (Part B) have different specific gravities (resin is usually denser than hardener), so a 2:1 volume ratio is rarely a 2:1 weight ratio. Always check the Technical Data Sheet (TDS).
Adheres to certified architectural formulas and standard ASTM D2471 Gel Time and Peak Exothermic Temperature of Reacting Thermoset Resins commercial trade provisions.
Accurate material takeoff requires reconciling nominal plan dimensions with real-world physical packaging and volumetric compaction. This engine evaluates Mold / Cavity Length, Average Cavity Width, Pour Thickness / Depth, Epoxy System Mix Ratio, Mixing Cup Loss Allowance against certified engineering multipliers.
\text{Total Fl Oz} = \frac{\text{Length (in)} \times \text{Width (in)} \times \text{Depth (in)}}{1.805\text{ in}^3\text{/fl oz}} \times 1.05Equation Reference: Thermoset Stoichiometric Volume & Displacement Formula. Calculated results provide both theoretical net volume and practical jobsite gross totals factoring standard shrinkage and trim cuts.
Measure length, width, depth, or gauge with calibrated trade tools. Confirm grade level and structural subbase.
Factor a 5% to 15% allowance depending on job complexity to prevent costly project shutdowns from mid-job shortages.
Round up to whole commercial packaging units (bags, rolls, panels) and compare raw material cost against regional trade rates.
Building departments across the United States reference municipal standard codes (including the International Residential Code IRC, National Electrical Code NFPA 70, American Concrete Institute ACI, and ASTM international specs). Designing below these minimum safety thresholds risks structural deflection, inspection failure, and permit revocation.
