Quick answer
How much resin for a table
For a table, length and width are not enough. You need the real volume of the river, cracks and voids, plus a practical allowance for mixing and finishing losses.
The key is moving from intuition to measurable volume: dimensions, voids, allowance and only then the right resin system.
If the result is large, do not buy resin immediately — first check maximum layer thickness, pot life and working conditions in the TDS.
How to choose
Measure the resin area as a volume in centimetres and convert cm³ to litres.
For an irregular river, split the table into shorter sections and sum them.
Check maximum layer thickness before deciding whether the pour can be done in one stage.
Add process losses
Raw wood can absorb resin, so a seal coat and a small reserve are usually safer.
Choose the right resin
Deep tables need deep-pour systems, not fast art resins designed for thin layers.
How to approach it in practice
Step by step
Measure the real pour space
Do not rely only on table dimensions. Measure length, average width and planned pour height; for irregular wood, split the shape into simpler sections.
Convert volume to litres
Calculate in centimetres and divide cm³ by 1000. This gives an immediate estimate of mixed A+B resin.
Add process allowance
Add reserve for cups, leaks, raw wood, degassing and finishing. Small voids often need a larger percentage allowance than big pours.
Check product limits
Compare the result with the TDS: maximum layer, working temperature, pot life and mixing method. Litres alone do not tell you whether one pour is safe.
Save the result with the project
If you quote for a client, save volume, assumptions and selected resin in the project card. It makes price changes and production easier.
Common mistakes
Mistake 1
Calculating length and width without pour height.
Mistake 2
No allowance for cracks, knots, cups and sanding.
Mistake 3
Buying resin before checking maximum layer thickness.
Mistake 4
Mixing litres, kilograms and A+B ratios without checking density.

FAQ
How many litres of resin does a table need?
Litres equal length × width × height in centimetres divided by 1000. Then add around 5-12% allowance.
Is a calculator enough for irregular wood?
Yes, but split the shape into smaller sections. A natural river edge can change the average width significantly.
Can I pour all the resin at once?
Only if the volume fits the maximum layer thickness and mass allowed by the resin TDS.
