Plaster Crown Duplication

Four separate plaster molds where constructed to reproduce this cornice. A leaking roof caused a significant amount of damage to this decorative plaster cornice or crown. The damaged plaster was removed which helps to determine the linear footage needed for the repair. A reverse plaster mold is then created, in this case four where needed, the molds are cast and are allowed seven days curing time. Generally casting over the footage needed assures extra plaster molding to allow for waste or fitting problems. Once cured, the plaster molds go through a series of trimming and reshaping steps to assure a seamless fit. Bonding agents are used where the new and the old meet making sure theses area’s don’t crack. The new plaster cornice is sanded, blended smooth, and is then ready for primer.  SAM_0504
