The Epoxy Volume Calculator helps you figure out exactly how much epoxy you need for your project. Whether you're covering a wooden table, pouring a resin river, or sealing a surface, you need the right volume of mixed resin and hardener. Using the wrong amount can lead to wasted materials, poor results, or extra costs. This tool helps make sure you mix just the right amount based on the area and thickness of your pour.
Formula of Epoxy Volume Calculator
1. Total Epoxy Volume
To calculate how much epoxy you'll need, multiply the surface area by the thickness of the layer you want to apply.
Total Volume = Area × Thickness
Area can be in square meters or square feet, and thickness in meters or inches. The final volume is usually given in liters or gallons.
2. Resin and Hardener Breakdown
If your epoxy has a specific mix ratio, such as 2 parts resin to 1 part hardener, the total volume needs to be split using this formula:
Resin Volume = Total Volume × (Resin Ratio / (Resin Ratio + Hardener Ratio))
Hardener Volume = Total Volume − Resin Volume
Quick Conversion Tips
If you're working in square meters and millimeters, 1 m² with a 1 mm layer equals about 1 liter of epoxy. For imperial units, 1 ft² at 1/8 inch thick needs around 0.0104 gallons.
General Reference Table
| Surface Area (m²) | Thickness (mm) | Total Volume (L) |
|---|---|---|
| 1 | 1 | 1.0 |
| 2 | 3 | 6.0 |
| 5 | 5 | 25.0 |
| 10 | 2 | 20.0 |
| Surface Area (ft²) | Thickness (in) | Total Volume (gallons) |
|---|---|---|
| 10 | 1/8 | 0.104 |
| 50 | 1/4 | 1.04 |
| 100 | 1/8 | 1.04 |
| 200 | 1/4 | 4.16 |
These are average values. You should still use the calculator for precise results.
Example of Epoxy Volume Calculator
Imagine you're working on a tabletop that's 2.5 square meters in size. You want a 2 mm thick epoxy layer, and you're using a 2:1 resin-to-hardener mix.
Step one is to calculate total volume: 2.5 m² × 0.002 m = 0.005 m³, which equals 5 liters.
Step two is to calculate the resin and hardener amounts. Resin volume is 5 × (2 / (2 + 1)) = 3.33 liters. Hardener volume is 5 − 3.33 = 1.67 liters.
This means you’ll need to mix 3.33 liters of resin with 1.67 liters of hardener to get the full 5 liters needed for the project.
Most Common FAQs
Using the wrong ratio can lead to improper curing. Always follow the ratio provided by the manufacturer to avoid problems like soft spots or incomplete hardening.
It's okay to make a bit extra, but be careful not to overdo it. Mixed epoxy has a limited pot life and can get wasted if not used quickly.
You can use a conversion tool to change inches to meters or feet to square meters. One inch is 0.0254 meters, and one square foot is about 0.0929 square meters.
