Estimate river table epoxy cost by resin quantity, deep-pour needs, waste, seepage, seal coat, kit size, and price per gallon.
River Table Epoxy Calculator
Estimate resin for a live-edge river table in one of two modes: a fast average-width estimate, or segment mode for irregular channels. Seepage, the seal coat, and cost are built in.

Next Step
Match the result to the right resin class
Use the estimate to narrow the resin class first. Then confirm product limits, cure behavior, and measurement assumptions before you make a buying decision.
Measurement diagram
What equal-length segments mean
The segment mode divides the full channel length into equal sections and uses one representative width for each section. For a 72 in channel, widths of 4.5, 6 and 7.5 in have a 6 in mean. At 1.5 in depth the raw amount is 648 in³ = 2.8052 gal. The example 12% waste, 8% seepage and 5% seal-coat allowances add 25 percentage points, giving 3.5065 gal. These are editable budgeting assumptions, not measured loss rates. For unequal sections, first calculate a length-weighted mean width or calculate each section separately.
Product data before mixing
Use the exact product documentation for mixing basis, maximum layer depth, mixed batch volume and cure or recoat conditions. A dimensional estimate and a purchase allowance do not supply those material limits.
What this calculator covers
- Switch between quick mode and segment mode depending on how irregular the river is.
- Adds seepage, seal-coat, and waste planning that simple river formulas miss.
- Outputs mixed quantity, approximate budget, layer guidance, and resin-class recommendation.
How to measure or set the inputs
- Mark measurement points along the river every 6 to 8 inches, and take more points where the channel changes direction or widens.
- Use quick mode only for a fast sanity check. Use segment mode when the river width changes materially across the slab.
- Leave seepage and seal-coat buffers on unless the mold, edges, and underside are already sealed and tested.
Common mistakes that cost money
- Reducing an irregular river to one average width and trusting the number too much.
- Ignoring underside leaks, wood soak-in, cup waste, and small leveling errors.
- Buying a table-top resin for a river depth that really needs a casting or deep-pour product.
Project checklist before you buy
- Confirm the mold or surface is sealed before mixing resin.
- Measure depth twice at the deepest point of the project.
- Add extra material for waste, seepage, and edge soak-in.
- Confirm the resin type matches the intended pour depth.
- Prepare cups, stir sticks, gloves, and a level work surface.
FAQ
Questions people ask before buying epoxy
How many width points should I measure?
As a rule of thumb, take a width measurement every 6 to 8 inches along the river. More variation means more measurement points.
Should I still add extra resin if the segment estimate looks precise?
Yes. Precision on the geometry side does not remove real-world loss from seepage, cup waste, and minor edge errors.
When is quick mode good enough?
Quick mode is good for a first-pass estimate or a river that stays fairly consistent in width. If the channel pinches, widens, or bends sharply, segment mode is the safer basis for ordering.
Does this page replace the resin data sheet?
No. Use this page to plan quantity and workflow, then confirm max pour depth, cure conditions, and the epoxy mix ratio against the product you intend to buy.
