How much resin for cutting boards
On a cutting or serving board, resin fills a river or a decorative recess, it does not coat the whole wood. What counts is the volume of that channel. Here are the grams by its measurements, which resin handles those depths and how to avoid cracks.
Resin for the board river/section
| Resin section | 1 board | 2 boards | 3 boards |
|---|---|---|---|
| River 25×4 cm · 1.5 cm | 182 g | 364 g | 546 g |
| River 30×5 cm · 2 cm | 363 g | 726 g | 1089 g |
| River 35×6 cm · 2 cm | 508 g | 1016 g | 1524 g |
How to calculate the river resin
Measure the length, average width and depth of the channel in cm. Volume = length × width × depth; convert to grams with density (~1.10 g/ml) and add 10 %. The table assumes a rectangular channel; if the river narrows, use the average width of three points.
Which resin to use
Past 2 cm in a single pour, a deep-pour resin like Artline Wood PRO: it cures slowly to dissipate heat and avoid cracks and yellowing. A thin coating at that depth overheats and cracks. If the channel exceeds the product max depth per layer, split the pour.
Food-safe finish
Cured epoxy is inert, but for direct food contact use a certified food-safe resin and respect full cure (up to 7 days). Even so, cut on the wood, not on the resin: epoxy scratches under a knife.
Example: river of a serving board
- Channel
- 30 × 5 cm
- Depth
- 2 cm
- Volume
- ≈ 300 cm³
- Resin
- deep pour
- Mix (+10 %)
- ≈ 360 g
Note: At 2 cm deep pour is already advisable; a deeper channel is poured in layers with a wait between them.

Frequently asked questions
How much resin does a board river take?
It depends on the channel volume. A river of 30 × 5 cm at 2 cm deep takes about 360 g of mix. Work out length × width × depth and add 10 %.
Which resin for a cutting board?
For the river, a deep pour if it passes 2 cm: it cures slowly and avoids cracks. For food contact, use a certified food-safe resin and respect full cure.
Can I cut on the resin part?
Better not: epoxy scratches under a knife and loses its gloss. The resin is decorative; always cut on the wood.
