The best product to build river tables is definitely Ecopoxy FlowCast.
FlowCast is a casting epoxy resin that looks like liquid glass. When the two parts are combined, it hardens to a crystal clear, durable finish.
You can use FlowCast epoxy by itself for a crystal clear finish or add liquid pigments and/or metallic pigments to create custom colours and effects.
FlowCast can be worked using the same tools you already have for woodworking such as a lathe, table saw, or belt sander, leaving you thousands of possibilities to create beautiful projects.
This woodworking epoxy is designed to keep a slightly unnoticeable flex, to allow seasonal movement of the wood without cracking.
You can pour FlowCast up to 1.5" (max recommended) in a sealed mold.
We have succeeded in creating a process with which you can build high-quality river tables yourself. Make sure to keep an eye on our blog as it will be posted online in the next few weeks.
