The

**calculation**for**determining**the amount of**epoxy**you**need**is a simple volume**calculation**. You simply multiple the length of the pour by the depth of the pour by the average width of the pour and then convert to liters.Also asked, how do you calculate how much epoxy resin to use?

**Amount of Resin Needed to Cast a Part**

- Formula for a Square/Rectangular Piece: Length x Width x Height.
- Example: If your piece is 3" x 4" x 2" = 24 cubic inches. Take 24 cubic inches x . 554 ounces per cubic inch = 13.25 ounces.
- Formula for a Round Piece: Pi x Radius (squared) x Height.

Similarly, how much resin will I need? You **will** require 1 kg of **resin** per millimetre of thickness required over a 1 sqm area. Therefore, to calculate **how much resin** to mix, simply multiply the thickness you require (in millimetres) by the area of your surface (in square metres).

1.6 square feet

If it's a wood or concrete countertop, you will **need** to seal the surface with a **clear** skim coat of **epoxy**. One quart will cover 60 square feet for one skim coat. To apply two coats, we **would** recommend a 2 quart kit as well as the **epoxy** you **need** for the color countertop pour.
