Epoxy pour planner
Plan an epoxy pour from start to finish — volume from a river-table outline, a rectangle, a cylinder, or area × depth; mix by volume or weight; the product's maximum pour depth turned into pours and waits; waste, kits and cost; the melamine form with a cut list; plan, section and isometric drawings; and step-by-step instructions.

How to use it
For a quick volume and mix, the epoxy and resin calculator is enough. This planner takes the same maths (it loads that tool’s code) and turns it into a project: the form to build, how many pours, how long to wait between them, what to buy, and what to do in what order.
How to use it
-
Pour — a river table is drawn from the river’s width at equal steps along the table and how far its centre wanders off the centreline (the outline is smoothed for the drawing; the volume uses the straight segments, the trapezoid rule). A rectangle, a cylinder (lamp cores, coasters cast in a tube), or any area × depth also work. Embedded objects takes a percentage off for stones, slabs or inserts.
-
Resin — the product class sets the typical mix ratio, densities and maximum depth per pour (tabletop coating about 1/8", casting about 1", deep pour about 2", extra-deep about 4"); Custom takes your data sheet’s numbers. The depth is split into the fewest equal pours within the limit. The wait between pours is the class’s typical range at 24 °C, stretched for a colder room (each 10 °C colder roughly doubles it).
-
Waste — 10–15 % covers what stays in the cups, drips, and soaks into the wood.
-
Mix — by volume, part A = V·a/(a+b); by weight the volumes follow from the densities so that the masses keep the stated ratio.
-
Cost — kit size and price give the kits to buy and the total.
The Drawings tab shows the plan (the river outline with its widths), a section with one layer per
pour, and an isometric of the form, the slabs and the pours (⛶ Full screen or f; Escape leaves).
Cut list gives the melamine form — base, long sides and ends, with the clearance you set — packed on
sheets; Shopping lists kits, tape, silicone, clamps and buckets; Steps has a step per pour with the
exact amounts of A and B. Print view prints everything.
Product values are typical of each class; your resin’s technical data sheet wins for ratio, densities, maximum depth, recoat window and cure.
Limits
It does not model heat build-up (exotherm) beyond the maximum pour depth, nor resin absorbed by very porous wood. Wait times are typical ranges, not guarantees.
