Return Policy

RiverCast is a clear epoxy system designed specifically for woodworking casting applications like deep pour river tables. It produces ultra-clear casts with minimal bubble entrapment. Because of its low reactivity and slow rate of cure, RiverCast can be poured into large inclusions up to 1-1/2'' deep without creating excessive heat or discoloration. Because of its slow rate of cure, it’s not ideal for small knots and cracks—check out MirrorCast (sold separately) for smaller pours.


  • Fill voids up to 1-1/2'' thick in a single pour
  • De-aerates rapidly
  • Contains no VOCs
  • Easy 2:1 mix ratio
  • Use with CastFX Dry Metallic Pigments or Liquid Colorants (sold separately) to create stunning effects!
