The maximum depth that TotalBoat Fathom epoxy can be poured is dependent on the volume of mixed epoxy. When the product is used for river tables and slab pours, the maximum pour depth is 2" per layer. When the product is being used for smaller castings using less than 1 gallon of mixed epoxy, the maximum pour depth is 3" per layer.
For all applications, wait at least 36 hours for the previous layer to cure before applying another layer of Fathom. The minimum recommended pour depth for Fathom is 1", as the cure rate of the epoxy will require a longer period of time to cure.
