Deep pour resin projects such as river tables, thick castings or large artworks demand careful calculation of the amount of epoxy required. Accurate planning by layer can make all the difference for a successful result.
Why Calculate Epoxy Resin Per Layer?
Pours exceeding 5cm in thickness require a staged approach for both safety and to maintain clarity. Epoxy resin, when used too thickly in one go, can risk overheating, yellowing or even structural issues. Layering the pour—measuring the amount of epoxy needed for each stage—helps you avoid problems and ensures predictable curing and quality.
How to Calculate Epoxy Volume for Each Layer
- First, measure the length, width and desired thickness (height) for each layer.
- Multiply these dimensions to find the volume of a single layer (in cubic centimetres or litres).
- Plan for a maximum single pour thickness according to the resin’s recommended limit—typically up to 5cm per layer for products like EpoxyTable 5-Five, or up to 10cm for deeper formulas such as Epoxytable 10-Ten.
- Divide the total required thickness by your chosen layer depth to estimate the number of pours and total resin you’ll need.
Practical Tips for Deep Pour Success
- Stick to the recommended maximum pour depths for your chosen epoxy.
- Allow each layer to cure as per the product instructions before pouring the next.
- Minimise air entrapment by pouring gently and using a resin formulated for deeper casting.
When This Matters
Layer-by-layer calculation is vital for projects such as river tables, artistic crystal-clear castings, or thick decorative blocks—anywhere exceeding safe single-pour depths. It helps prevent heat build-up and maintains a flawless finish throughout the entire piece.
