Resin and finish planners for woodworkers
Describe your project, not its volume or square footage. Get back a plan you can shop from: how much epoxy or finish, in which container sizes, poured or brushed in which order.
Resin planners
- River table epoxy calculator
Deep pour volume from several width measurements, the number of layers, seal and flood coats, and kits to buy.
- Epoxy resin calculator
Mixed epoxy for rectangles, rounds and odd shaped molds, with layers and batches.
- Bar top epoxy calculator
Seal coat and flood coats for bar tops, counters and tables, edges included.
- Epoxy mix ratio calculator
Resin and hardener amounts for any ratio, by volume or by weight.
- Live edge slab calculator
Board feet and cost for slabs with uneven widths.
Finish planners
- Wood finish calculator
How much polyurethane or oil a tabletop, bookcase or set of doors needs, every face counted.
- Finish coat schedule planner
Every coat timed around your working hours, with light use and full cure dates.
Guides
- Deep pour vs table top epoxy
What each one is for, and why a river table uses both.
- How to measure a river table for epoxy
Length, width at several points and depth, with diagrams.
- How many coats of finish
Typical coats for each finish and when to stop.
- Epoxy mix ratio: weight vs volume
Why 2:1 by volume is not 2:1 on a scale.
Why these tools work the way they do
Most calculators ask for a number you do not have, like the cubic inches in a river or the square feet of a bookcase. These start from the thing on your bench. Every tool works with any brand: the coverage, mix ratio and maximum pour depth fields are pre-filled with typical values, and you replace them with the numbers on your own label. Each page shows the formula and a worked example, so you can check the math yourself.
