I have quite a bit of experience with this having built dozens of displays for zoos. However, I used my own custom mixture and was not worried about weight.



The mixture you mentioned sounds interesting and I'd like to try it someday.



I think it would be very easy to sculpt a form out of high density polyurethane foam and then cover than with screen or lath as a matrix for the mixture.



Then it could be smeared onto the screen and textured.



I made my own molds by pouring a two part rubber compound onto rocks, bark, etc. As my concrete mixture cured I pounded the molds into the curing concrete and pulled it away. I could work my way across a 2 sq. ft. area before the mixture set up too much to be worked with.



But for a small project I think you could use actual rocks, etc. to texture the mixture. Spray vegetable oil onto the rock, pound it into the curing mixture, pull it away and repeat.



I think you could take a plastic box and coat it with screen and this mixture. That would make the inside easy to clean and the exterior would be natural looking.
