I have done several large pour epoxy projects. You can for sure repour over existing layers, in fact I have found that is the only way it seems to work. I can never get one pour to be enough, it is usually 3 pours. My favorite epoxy for large pours is Liquid Diamonds or similar. You can generally do another pour in 24 hours. If you wait much longer you MUST scuff the surface or it won't bond properly...trust me on that one. I have used different (although similar) epoxies over each other with acceptable results.
Live a life worth celebrating!
