How much epoxy do you need?

Are you planning to start working with epoxy casting resin and do you want to buy epoxy casting resin ? But do you have no idea exactly how much epoxy you need? We are happy to help you.

Calculate the amount of epoxy required yourself

There is a simple rule of thumb to determine how much epoxy you need. Keep in mind that this remains an estimate, so always order a little more epoxy.

Use the following formula to calculate the amount of epoxy required: length in centimeters x width in centimeters x layer thickness in centimeters x 1.1: 1000.
You multiply the surface area by 1.1, because 1100 grams of epoxy is equal to 1 liter. Then divide the result by 1000, so that you know how many kg you need.
With this formula you can easily and accurately calculate the number of kilos of epoxy you need for a rectangular or square table top. See the bottom of the page for an example of the epoxy required for a table. For a round table top use the formula: 3.14 x radius in centimeters x radius in centimeters x layer thickness in centimeters x 1.1.

How much epoxy needed for silicone mold?

If you are pouring epoxy into a silicone mold and you want to know how much epoxy, jesmonite or plaster you need, you can do the following. By weighing the silicone mold you can determine how much epoxy casting resin is needed. You first weigh the empty mold and then the mold filled with water. The difference in weight is the number of liters that fit in the silicone mold. 1 liter of epoxy weighs 1.1 kg. So you have to multiply the number of liters that fit in the mold x 1.1.
For example, if 200 ml of water fits in the silicone mold, the formula is as follows: 200 x 1.1 = 220 grams of epoxy required.

Example of epoxy needed for table

See below an example of how much epoxy you need to coat a wooden table. How much epoxy you need depends on the desired layer thickness. For tabletops and art projects, an average epoxy layer ranges between 3mm and 6mm. For floor coatings, the layer thickness may differ, but a thickness of 3 mm is usually sufficient.

1. Determine the surface area

Accurately measure the surface of the table or object you want to coat. The table in our example is 160 x 90 cm. So the surface area is 1.44 m² (160x90).

2. Calculate how much epoxy you need

To determine how much epoxy you need, multiply the surface area by the desired layer thickness. This gives the required volume of epoxy in cubic meters. Always add an extra margin of 10 to 20 percent to your calculation to ensure you have enough epoxy for your entire project. This helps catch any errors or waste. In this case it is 1.44 m² x 120% = 1.73 m². We then assume an average layer thickness of 3 mm. 1.73 m² x 3 mm layer thickness = 5.2 m². This table therefore requires 5.2 m² of epoxy.

3. Buy the right epoxy

With the calculated amount of epoxy you can purchase the necessary materials. Make sure you use the correct mixing ratio and follow the manufacturer's instructions carefully for best results. At epoxy store itsOkay you will find high-quality epoxy products for every type of project. We recommend this epoxy for crystal clear coatings.
