Thicker than a good chili, thinner than chunky peanut butter.Slop the mix on top of the mold carelessly, using a tool rather than gravity to get the mold to fill.Another way to get battle damage is to put broken pieces of cured plaster in the mold, then fill the mold with an aggregate thickened mix. EDIT: once set, flick some, but not all of the broken plaster away and you'll have a good rough broken look.Either way DON'T shake or vibrate the mold too much since that will reduce the air bubbles you are trying to get.</blockquote>
