RiverPour 3kg Kit - Deep Pour Epoxy Resin

The RiverPour 2:1 Epoxy Resin, 3kg Kit is the perfect size for artists and makers who want professional-grade results without committing to bulk quantities. Designed for deep pour projects such as river tables, decorative castings, and resin furniture, this kit provides the ideal amount of resin and hardener for medium-sized pours, giving you the perfect balance of control, convenience, and quality.

Part of Just Resin’s professional RiverPour range, this 3kg kit delivers the same crystal-clear finish, extended working time, and low exothermic reaction trusted by professional resin artists. It’s a practical choice for those working on smaller tables, casting blocks, or detailed encapsulations, where precision and performance matter most.

The 3kg format is easy to handle, mix, and pour, especially when working solo or in compact studio spaces. You’ll enjoy the same optical clarity, UV stability, and strength found in the larger RiverPour systems, now in a convenient, manageable kit size that still delivers professional-level results every time.

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:

3kg = $49.83 per Litre (standard pricing)
