Resin Project Calculator

Estimate how much mixed resin your project needs and split it into Part A and Part B using the manufacturer's volume- or weight-based ratio.

1. What are you filling?
2. Manufacturer mix instructions
Important: Use the ratio basis printed by your resin manufacturer. A 2:1 ratio by volume is not automatically 2:1 by weight. Density varies by product.

How to use this resin calculator

Measure the area you plan to fill, choose your pour depth and quantity, then enter the exact mixing ratio specified by your resin manufacturer. The calculator adds your chosen waste allowance and separates the total into Part A and Part B.

Weight-based resin mixing

If your manufacturer gives a ratio such as 100:45 by weight, select Ratio by weight. When calculating from physical project dimensions, enter the manufacturer's Part A and Part B densities so the required project volume can be converted into the correct component weights.
