Ornamental Fireplace Mantle

Posted on Posted in Cast Plaster, Ornamental Plaster

Greetings from the plaster industry. A family in Oakwood wanted to build an addition with features to match the existing home. These features included a carved stone fireplace mantle and Corinthian column entrance. To achieve this work, the plasterers first coated the existing features with a rubber mold then created a removable “house” (support encasement). This allowed them to take the mold back to the shop and cast new features using high-early cement in a color to approximate the existing.  The job was complicated by the fact that code required the new fireplace to be slightly bigger than the existing one. Therefore, sculptors had to be employed to modify the mold to allow the expansion. The finished work won an award in the Dayton Builders exchange Craftsmanship ceremony.
