No, I just poured some asphalt emulsion into a bucket of slurry and cement mix, and then cast it into a panel. No coating, it was homogeneous.
The panel did float without absorbing any water. After eight hours or so I took it out of the water and set it out in the weather. As it weathered the black color faded. At last sight it was doing well, but it eventually disappeared. I suspect a helper tossed it into the mixer along with various pc scraps so it is probably somewhere in my domes now. : )
AE could be just painted onto the surface of papercrete and would make it shed water. Eventually the coating would need to be renewed as the AE slowly washes away.
