How long does it take for epoxy glue to fully cure?

Full cure of a two part epoxy can be several days. However adequate strength for further assembly, or packaging can be reached within minutes or hours. To increase full cure speed, heat can be used. The general rule of thumb is for every 10C increase in temperature the cure time is cut in half.

Should I sand between coats of epoxy?

Sanding will not only get out the imperfection but will also serve to provide some tooth between the first and second layers. It will look very scuffed in the short term but do not worry, once you pour the second coat over top, all of those sanding marks will disappear.
