TotalBoat TableTop Epoxy is a viscous material, with a reasonable amount of working time. The primary reason that TotalBoat Tabletop Epoxy does not self level is that it was not applied under the directed environmental conditions. Always ensure sure the product, substrate, and ambient air are all within the specified temperature range before applying, and ensure that the environmental conditions are maintained throughout the whole. It will flow and level better if it is spread evenly with a spreader, or a straight edge as soon as it is poured. Waving a heat gun or torch over the poured for a few seconds at a time will also help it flow at the same time as bring bubbles to the surface to pop before the working time has elapsed.
