Why is RiverPour sold in kilograms, and its conversion to litres.
When measuring both small and large amounts of epoxy resin, it can often be much easier to simply weigh Part A & B on a set of scales in the same mixing vessel, as calibrated measuring cups can be limited in size and not always readily available.

The Just Resin team, have been creating all sized castings for many years, and we struggled when it came to 20+ litre pours, as calibrated vessels are hard to come by for this volume of epoxy. We found ourselves converting the volume to weight and measured on a set of scales. As RiverPour is purposely designed for River Tables and other large casting applications, it was a must that we formulated this system to be measured by weight, for pure ease of use.


We know most Resin Casting kits are usually available in litres, and this can make it tricky to compare between price per litre and price per kilogram.

We went ahead and did the conversion for you, making it easier for you to compare with other products on the market, see below:

15kg = $33.73 per Litre (standard pricing)
