A flexible mud pan or trough constructed from a structurally supporting material, within which is held a volume of a viscous and settable compound. Upon setting and drying of remnants of the compound not applied, the pan is collapsed or otherwise folded/twisted, causing the flaked remnants to be forcibly disengaged from the flexible surfaces of the pan, the pan subsequently returning to a pre-existing physical configuration reconditioned for future use. |
