If you want to create a thinner coat, well, you’d need less but you also probably shouldn’t try that. Is that thick enough for you? If you are trying to create a thicker coat of epoxy, you’re going to need a lot more. Most epoxies are designed to self-level to create a coat that is 1/8 of an inch thick.
When calculating the average width of the pour, you can measure the width every 6 inches along the entire workpiece and then divide by the total number of width measurements you took to determine the average. 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. The calculation for determining the amount of epoxy you need is a simple volume calculation. These specifications are noted on the packaging. The mixing ratio between resin and hardener varies according to manufacturer and product.
