I _think_ it's the acidity that prevents a hard set--for example it would neutralize lime. Before, I thot it was a good idea because of the digested fibers in it. I've seen an earthen plaster that had weathered, sifted horse manure added. It had added lime, but I'm convinced it was completely neutralized/useless. It had a hollow/frangible/friable quality after drying. *Lootvik*
