Ornamental plastering is alive and well. The following pictures are from St Mary's Church in Marietta, Ohio. Besides extensive renovation of the existing plaster, the designer wanted to add ornamental plaster. The first set of pictures are of the curved arch added at the upper dome windows. These shapes were run on a bench and stuck to the existing plaster walls.

Running and sticking the pieces was a relatively easy way to add decoration to the wall.

For the area just under these windows, the designer wanted to add an extensive amount of the same shape. To accomplish that, the contractor made a rubber mold and cast the pieces using a thinshell method. This cut down on weight and made handling much easier. This is the way to go if there is adequate quantity.



The last picture in this set shows the cast pieces in place with the miters completed and ready to be painted.



Preparing for a rubber mold. The designer needed twelve more medallions to complete the project. Although they look fairly large and heavy, the casting method allowed them to use light filler so they would not be so weighty.

This picture was taken before the job started. Notice the imperfections in the existing surfaces.

All the plastering was done with craftsmen from Dayton.

The Dayton Bureau for Lath and Plaster is funded by contractors through the Dayton area Plasterer’s Union. It seeks to promote quality work through the use of trained craftsmen. If you have project details or specifications, Ken Oren is available for questions. There is no charge to architects when the project in question is offered to local bidders. The Bureau has purchased ASTM Section C and AutoCAD LT for reference and convenience in addressing design issues. If you wish to email an item for review to, your query will be promptly addressed.
