Nevell Group used the stucco Santa Barbara finish along with thousands of linear feet of control joint to achieve a look similar to stone. The challenge was to come up with a finish that would model similar to a stone look. NGI performed a mockup on site, which was approved, then submitted a detailed layout of the joints in fully dimensioned drawings. The lathing work was extremely time consuming to get the projection from the adjacent surfaces, line up all the joints and work with multiple radii. The layout of these joints had to be exact so that as you look down the row of columns and arches, the joints are uniform. At peak the barrel ceiling in the church was 63' 7", so NGI engineered a scaffolding system to provide a continuous/tiered platform for the framers, hangers, lathers and plasterers to work.
