Epoxy Resin Calculator

Epoxy resin is widely used for crafting, coating, casting, and construction projects. However, calculating the right amount of resin and hardener can be tricky. Using too little can leave areas uncoated, while too much leads to waste and extra cost.

Epoxy Resin Calculator

What Is the Epoxy Resin Calculator?

The Epoxy Resin Calculator is an online tool that estimates the amount of epoxy resin and hardener required based on:

  • Project dimensions (length, width, height/thickness)
  • Desired thickness or coating depth
  • Resin-to-hardener mixing ratio

It’s perfect for DIY enthusiasts, woodworkers, artisans, and industrial users who want to save time, money, and materials.

Why Use an Epoxy Resin Calculator?

Using the calculator helps you:

  • Avoid wasting expensive resin
  • Ensure even coating and proper curing
  • Plan project costs accurately
  • Save time measuring manually
  • Improve the quality of your finished product

How to Use the Epoxy Resin Calculator

Using the calculator is easy:

  1. Enter project dimensions: length, width, and thickness
  2. Select units: inches, centimeters, or meters
  3. Enter resin-to-hardener ratio: common ratios are 2:1 or 1:1
  4. Click Calculate

The calculator provides:

  • Total resin required
  • Amount of hardener needed
  • Volume in liters or gallons (or preferred unit)

Epoxy Resin Calculation Formula (Plain Text)

The basic formula for calculating resin volume is:

Volume = Length × Width × Thickness

Convert to desired units (liters or gallons).

Then, calculate individual components based on mixing ratio:

Resin Amount = (Volume × Resin Part Ratio) ÷ (Resin Part + Hardener Part) Hardener Amount = Volume − Resin Amount

Example Epoxy Resin Calculation

Scenario

  • Project: 2 ft × 3 ft table top
  • Desired thickness: 0.5 inches
  • Mixing ratio: 2:1 (resin:hardener)

Step 1: Calculate Total Volume (in cubic inches)

Volume = 24 × 36 × 0.5 = 432 cubic inches

Step 2: Convert to liters (1 cubic inch = 0.016387 liters)

432 × 0.016387 ≈ 7.08 liters

Step 3: Calculate Resin and Hardener

  • Total parts = 2 + 1 = 3
  • Resin = 7.08 × (2 ÷ 3) ≈ 4.72 liters
  • Hardener = 7.08 − 4.72 ≈ 2.36 liters

Result: Use 4.72 liters of resin and 2.36 liters of hardener.

Benefits of Using the Epoxy Resin Calculator

  • Accurate material estimation for any project size
  • Avoids costly mistakes or shortages
  • Helps maintain proper resin-to-hardener ratios
  • Saves time in preparation and measurement
  • Supports multiple units and project types

Helpful Tips for Using Epoxy Resin

  • Always measure accurately using a scale or measuring cup
  • Mix resin and hardener thoroughly for proper curing
  • Work in a well-ventilated area
  • Add pigments or dyes gradually if desired
  • Clean tools promptly to avoid resin hardening
