How Much Resin for 2 Inch Depth
A 2 inch deep epoxy pour is common for thick river table channels, chunky mold casts, and decorative inlays. At this depth, volume adds up fast — and the wrong epoxy type will cause dangerous overheating. This guide gives exact volume estimates by surface area and explains which products are safe for 2 inch pours.

1.805 converts cubic inches to fluid ounces. Add 10% waste to the result.
Example: a river channel 8 inches wide × 48 inches long at 2 inches deep:
8 × 48 × 2 = 768 cubic inches ÷ 1.805 = ~426 fl oz (~3.3 gallons)
Volume Table — Common Areas at 2 Inch Depth
| Area (L × W) | Volume (fl oz) | Volume (gallons) |
|---|---|---|
| 6 in × 12 in | ~80 fl oz | ~0.63 gal |
| 6 in × 24 in | ~160 fl oz | ~1.25 gal |
| 6 in × 48 in | ~319 fl oz | ~2.5 gal |
| 8 in × 48 in | ~426 fl oz | ~3.3 gal |
| 10 in × 72 in | ~798 fl oz | ~6.2 gal |
| 12 in × 12 in | ~160 fl oz | ~1.25 gal |
| 12 in × 24 in | ~319 fl oz | ~2.5 gal |
| 12 in × 48 in | ~638 fl oz | ~5 gal |
Add 10% to all volumes for cup residue, mixing loss, and overflow when filling the mold or channel.
Epoxy Type for 2 Inch Pours
Standard coating epoxy will overheat at 2 inches. Only use a deep-pour casting resin rated for 2 inches or more per layer. Check the product's TDS for its maximum single-pour depth.
- Deep-pour casting resin (rated 1–4 in): Safe for a 2 inch single pour. Cures slowly (24–72 hours) with low heat output.
- Standard coating / tabletop epoxy: Maximum 1/4 inch per layer — never use for 2 inch pours.
- Structural / laminating epoxy: Varies by product — check TDS before use.

Frequently Asked Questions
How much resin do I need for a 2 inch deep pour?
Multiply your area (length × width in inches) by 2, then divide by 1.805 to get fluid ounces. For a 12×24 inch area at 2 inches: 576 ÷ 1.805 ≈ 319 fl oz (~2.5 gallons). Add 10% waste. Use the volume calculator for any custom size.
What epoxy should I use for a 2 inch pour?
Use a deep-pour casting resin rated for at least 2 inches per layer. Standard tabletop epoxy is only safe to 1/4 inch per layer — at 2 inches it will overheat, crack, and yellow. Check your product's technical data sheet for its maximum pour depth rating.
