English Guide: How to use the Epoxy Calculator?
Mastering the Epoxy Calculator is the secret to a professional finish on river tables, art pours, and flooring projects. Resin is an expensive chemical compound; mixing too much leads to waste, while mixing too little can ruin your entire piece. Follow this guide to use our 100% free solver:
Step-by-Step Instructions
1. Choose Geometry: Select 'Rectangle' for standard tables or 'Round' for clocks and coasters. This changes the volume formula from LxWxD to πr²xD.
2. Input Dimensions: Enter your mold's exact dimensions. For river tables with irregular edges, use the "Average Width" method.
3. Select Ratio: This is crucial! Check your resin bottle. A 1:1 ratio is typical for coatings, while a 2:1 ratio is used for deep casting.
4. Seal Coat Option: If you are pouring on wood, check the 'Seal Coat' box. This adds extra volume for a thin preliminary layer to prevent air bubbles.

Why is the Mixing Ratio (1:1, 2:1) So Important?
Epoxy isn't just glue; it's a chemical reaction. Our resin calculator accounts for different formulations because mixing the wrong amount of hardener will result in a sticky, "rubbery" surface that never cures. A 1:1 ratio resin is formulated to cure fast in thin layers, whereas a 2:1 deep pour resin cures slowly to avoid "thermal runaway" or boiling.
Frequently Asked Questions (FAQs)
How much extra resin should I mix?
We always recommend mixing 5-10% more than the calculated amount. Some resin will always stay stuck to the walls of your mixing cup.
Can I mix by weight instead of volume?
Warning! Resin is heavier than hardener. A 1:1 volume ratio is NOT a 1:1 weight ratio. Check your label for the "Weight Ratio" before using a scale.
How thick can I pour epoxy?
This depends on your resin type. Tabletop epoxy is limited to 1/8", while Deep Pour resins can go up to 2-4 inches per layer.
